Tourna Ennox - Electronic Tension Head

Semi-Pro

This seems to be new from Tourna and the exact product that is available on various iterations of the Stringmaster V3 from tennisman.de.
Cost is approx +$200 over a Wise with the advantage of glide to activate and chain vs belt drive (lower noise?).
What do you guys think, would you pay the extra for the Ennox or be more comfortable with the Wise as mature product with easy to access and reasonably priced parts and service?

@mauricem,

For whatever reason, Tourna appears to be using "Ennox", whereas tennisman.de uses "Ennoxx".
Below, I will be using the latter spelling, as it is what I'm accustomed to - based on how the unit was introduced to me.

The Ennoxx tensioner got onto my radar several months ago (as you already know) - back in early February, if I remember correctly.

I was helping out yet another forum member regarding various machine options they might consider.
Over the course of that conversation, I brought up the tennisman.de machines (including the Stringmaster Deluxe).
Tennisman.de had always offered that machine available w/ a Wise 2086 unit (as well as with a standard DW tensioner... or even no tensioner at all, should one prefer either of those options).
That's where I first became aware of the Ennoxx unit (which I think might, just might, actually be produced by Xpider).

At any rate, once the Ennoxx actually became available (I believe that was around late March?), they also began offering a couple Stringmaster machines (Deluxe, & the 4000) with the Ennoxx option (dubbed "V3"), but it's still also available with a Wise 2086... or with a DW... or with no tensioner at all.

As soon as I saw the Ennoxx, I liked certain aspects of it over the Wise 2086 (which I have owned/used previously).
I won't list those specific aspects here, but suffice it to say that - for me - I think I'd be willing to pay the extra $217-225USD for these particulars (* depending on just what hoops I might have to jump through, should the machine need to be serviced).

Note: The $217USD figure above is reflective of the difference in price if one opts to get the Ennoxx tensioner on a Stringmaster Deluxe, rather than the same machine with the Wise 2086.
If the Ennoxx tensioner is purchased, stand alone, the price is about $225 more than the $750 that a new Wise currently costs in US dollars.

In other words, I think the Ennoxx is probably worth the $975 from tennisman.de
However, I wouldn't be willing to pay $1200USD (the price that doittennis appears to be charging) for the "Tourna" branded one.

Furthermore, for anyone who might be considering purchasing a Wise 2086 and then upgrading its linear gripper/diabolo assembly (as @dsp9753 did... see link below), consider the total costs involved.
$750 Wise 2086
$130 Gripper/diabolo assembly from the Chinese online supplier
That's already $880 (not including tax/shipping... potentially twice).

As for myself, if I had nothing already - and was looking to buy new - I think I'd rather throw in the extra $100 to have the chain driven Ennoxx (in addition to its other niceties), over the Wise 2086.


It would likely be helpful for @AnthonyTeaDough to chime in here with his thoughts, since I believe he ordered the Stringmaster Deluxe V3 about 3 weeks ago.
I presume that it would have arrived to him by now, so perhaps he can provide some first hand feedback.
Now that I've invoked his name, he should get a notification regarding this thread/post.

Thanks Wes,
very helpful as always. One of the reasons I made this post was you mentioned you weren't certain the two units were the same but that video and listing should hopefully confirm they are the same product leaving aside the remote possibility tennisman has undertaken some major obfuscation under cover of a typo!

I agree the Ennox(x?) seems to be worth the extra approx $300 AUD over a Wise (or $100 with glide activation) the only slight hesitation arising from unknown service and parts logistics which I'm still trying to confirm.

The Ennox is made by Xpider, and way way better than the Wise.
Good to hear, could you expand on some of those ways please?

@kkm, can you confirm whether the entire tension module is being made by Xpider... or if it's just the linear gripper/diabolo assembly which they are producing?

This is the aspect that I was unsure of when discussing the unit with @mauricem and others.

I had showed them the Xpider video above, regarding the gripper/diabolo assembly, and then also showed them the still photos on tennisman.de
Therefore, I felt somewhat confident that part of the Ennoxx was coming from Xpider.

However, whom/where the rest of the unit was being produced... I'm in no position to vouch for that (and openly/honestly explained this to @mauricem and others).

Thanks Wes,

the only slight hesitation arising from unknown service and parts logistics which I'm still trying to confirm.

Knowing that you're in Australia, that's why I was reluctant to recommend which route (Ennoxx vs. Wise) you should probably go with.

Hence the caveat...
@mauricem,

I think I'd be willing to pay the extra $217-225USD for these particulars (* depending on just what hoops I might have to jump through, should the machine need to be serviced).

Obviously, a bit of further reasearch/investigating is in order to come to that determination.

Cheers, Wes

I’ll put it this way: there’s no way that Xpider is producing just the linear gripper/diabolo assembly.

I missed this thread, but when I e-mailed Dirk at tennisman, he said the module was made by Xpider and that he'd been asking them to build something like this for a long time.

Edit: I only have 3 frames on my machine so far, but I'm liking this unit. The UI is simple enough and doesn't have any head-scratcher choices so far. The glide to activate feature is pretty neat, but I'm getting used to having to hit the knot button before threading the string since it's so easy to activate the tensioner. The rear rocker button feels a little cheap (sloppy), but works as you'd expect it to, so no real complaints there. I'm just used to a little more spring force on the lever. I'm sure it's just muscle memory and/or a process thing I have to get used to.

I assume you’re talking about the clamp bases. Try adjusting them. There’s a good video on the tube.
One other thing, clean the turntable rails with WD40 and the clamp bases move easier.

EDIT: There’s a seal over the 2 allen screws holding the bases on the rails. Some didn’t want to take the seals off but I do so I can clean rails and bottom of the bases easier.

Yeah, I'm referring to the tensioner module being discussed in this thread, the Ennox(x) unit. The activation switch/lever is what I'm talking about.

What’s your impression on the speed of the tension head @diredesire?
As a first impression, I thought it was fine. I only strung on high, though. I was definitely waiting a little bit before popping a clamp at times, but I'm actually a little rusty since I haven't strung regularly for a while. I can tell my movement isn't very fluid, and I'm not really on auto pilot. Even though the clamp action is very similar to the sensor, I am actually finding myself thinking about it more than I'd have expected. I'll post about it in the near future. From a mounted frame with mains in hand, I can still string sub 16 mins, so I don't think the tensioner is dramatically slow, or anything. It'll probably be way out into the distant future, but I imagine I'll be able to get this and the Sensor side by side to do some comparison tests. My good buddy has my old machine, and I'll probably visit sooner or later.

I might also set up a measurement rig for tensioners if I ever get some free time - would be super interesting to characterize stuff like prestretch and overshoot, etc.

What about the overall quality? How does the new rig compare to the sensor in terms of turntable rigidity, smoothness of operation, mounting of the frame, smoothness of base clamp movement and operation, tensioner smoothness and noise level, etc. Does it operate and feel like a pro shop quality machine? This is what i'm most curious about. For example, when i got my first 2 eagnas machines, it was apparent quality was not a priority. Then I got an Ektelon Neos 1000 which did feel much higher quality. Tighter tolerances. Smoother operation of glide bar clamps and turntable. Then I got a Gamma 6004 + Wise which screamed home stringer quality. I say screamed because the Wise was so loud and rickety when pulling and releasing tension. The Gamma machine flexed so much that it was so visible and obvious to my eye. Upgrading to the Sensor, it felt like a pro shop quality machine. Switching to the Ghost 2, it still feels like a pro shop quality machine in every aspect of its operation. Both the Sensor and Ghost 2 have a solidity and overall high level of refinement.

When the captor in my sensor finally died and I bought a ghost 2, I felt that the sensor billiard frame mounts were designed better than the ghost 2. The sensor billiards are lower profile so they allowed the string to be clamped closer to the frame for the center 2 mains. The side frame supports on the sensor were also lower profile and angled off in a way that was less likely to block holes. I also preferred the sensor string clamps because they slid over the hosel rather than into the hosel. With the string clamps sliding over the hosel, there was no way for the string clamp to pinch the hand when you let the clamp drop down onto the base after unclamping the string. Because the shaft of the string clamps on the ghost 2 slide into the hosel, when you hold your hand around the string clamp to catch and move it over when you unclamp the string, the string clamp can pinch the skin between the thumb and index finger. That was annoying for a few racquets until I got used to how far I needed to position my hand to catch it. The sensor string clamps consistently allowed me to clamp closer to the frame than the ghost 2 string clamps on the center 2 mains and the outermost 2 mains. I felt the tension head of the ghost 2 was even smoother and more refined than the sensor’s tension head which was already very quiet and smooth. I also love the electronic auto brake on the ghost 2 vs the manual screw knob brake of the sensor. I preferred the curved rails on the sensor over the straight rails of the ghost 2. Going from straight rails to curved felt smooth, natural and intuitive when I went from the gamma 6004 to the sensor. Took no time to adjust to. Going from curved rails (sensor) back to straight rails (ghost 2) took about 5 racquets to adjust to. I felt like I was fighting the bases on the first few racquets until I stopped pushing the bases and just swiveled them while pushing. Both turntables and towers are plenty sturdy and rigid. I'm certain nothing is sturdier than the sensor, but the sensor's turntable and towers are likely over engineered. Even though the ghost 2's turntable isn't nearly as heavy and thick, it's plenty sturdy as I don't detect any hint of flex when pulling tension. Going from the down press base clamps on the sensor to the switch action lock/push button release base clamps on the ghost 2 took me 1 racquet to get used to. I thought this change would be significant, but after 2 racquets, I wasn't missing the down press base clamps at all. Felt that the ghost 2 switch action lock/push button release bases were actually easier and more ergonomic to use since I would unlock the bases first before releasing the string clamps. If I was taking advantage of the gravity release functionality and releasing the string clamps first and letting the clamps drop into the hosel to auto release the bases, then I feel the sensor would hold a slight advantage.

do you feel it's possible for string to get caught under the lever of the down press base clamp where pulling on the string could accidentally release the base? the sensor base design where the base lock lever is pushed down and sits flush with the body of the base, made it impossible for string to get caught under so it was impossible to accidentally unlock. while the ghost 2 has a lever to lock and string can potentially get caught around the lever (haven't had it happen yet), the base can not be unlocked with reverse pressure applied to the switch lever. The base can only be unlocked by pressing down on the large round smooth button.

I'll go into more detail in a separate thread so as not to derail this one, although, to be fair, if you slapped this tensioner on another tourna machine, you'd basically have an identical setup vs. what I have, so I'll try to answer and be brief. I'd say it's pro-shop quality for the most part. I know exactly what you mean, and I have been surprised in a good way.

Overall quality is actually quite a bit higher than I anticipated. I thought the turntable was going to be thin-ish stamped metal, but it's substantial. Same with the machine base. It's bent and bolted to other parts, so I expect the rigidity is a non-issue. Tensioner is quieter than expected, but I can't even make a qualitative comparison since it's been so long since I've worked with my sensor on a daily basis. I think it's quieter, though.

Clamps are a sleeve, not a shaft, so no pinch. Clamps are slimmer than I recall the sensor's clamps being, so having both at the start of a frame side-by-side is no problem. I actually broke my brake because there weren't instructions for assembly, so still waiting on how to reassemble it - no word yet.

I don't like the curved rails for reasons I mentioned elsewhere, I'll note it in my impressions post. Agreed on sturdiness of sensor. I've always found gravity release to be hit and miss enough where it's annoying to use. Even when the clamps do drop (which I'd say is roughly 50% of the time), they only release the base at best 75% of the time (of the 50%), so i either whack the clamp head down, or I release manually. It's enough to be annoying. There's definitely a lip to the clamp release, and yes, you can manually release by pulling up on the lip (vs. pushing down on the release rocker). I haven't tried to catch a string on it, will note that before posting impressions. I've definitely popped a lever on the clamp head or base before, so I know precisely your concern. More later in the separate thread! I took lots of pics.

:cool:(y) awesome! i knew you'd know what i mean. :cool:(y)

I agree with you on gravity release. you have to "think" about where you clamp the base down so that the string clamp is aligned just right so when you unclamp the string the clamp is able to drop down into the hosel without catching the string...which as you said it hit and miss - mostly miss in my experience. :-D which is exactly why i never used it and just released the base manually.

Wow. How'd you break the brake? o_O When i assembled the Ghost 2, the brake didn't require any assembly. The fact that the brake can be broken so easily doesn't seem to be a well thought out design and is concerning.

Are the screw placements on the Ennox sufficient for mounting onto the smaller blue Gamma X-2 or X-6FC bases?

Highly considering this over the Wise.

I don't actually know.
However (based on what I've seen), I suspect that (like the Wise) it will not mount onto machines with that type of base/platform easily.

I think that the bolt pattern (as well as the "footprint" of the Ennoxx) will likely be better suited for DW machines that have a larger area/platform on which to reside.

Probably machines similar in design/layout to:
Tourna CS-150/175
Gamma Prog. 200/602/602FC
Alpha Pioneer DC+
Etc. etc.

I'm following the discussion with interest to see if anyone eventually retrofits a lockout machine with the Tourna Ennox head (instead of a Wise machine). I'm curious how well it retrofits on various machines.

I've seen the manual.
It's designed to be able to mount on a crank/lockout machine equally as well as a DW.

I presume that you did watch the video in post #1 above, correct? :cautious:

Yes, I did see the video. I guess I'm curious as to how high or low it will be in relation to the stringbed. That drop weight mounting example looked rather low.

I recall that Wise had an adapter for some Gamma machines to raise the tensioner closer to a similar height as the stringbed.

Judging from the video in post #1, the Ennoxx doesn't appear to sit too low on either type of machine (crank/lockout or DW). In both cases, it seems to reside right about where you'd want it to - just below the height of the racquet's handle/grip (so, roughly 1.5-2 inches below the level of the string bed).
In my opinion, you actually want the tension head to be slightly lower than the racquet. This assures that you will have/maintain 360° rotation (as opposed to not having 360° rotation).

FWIW, I would certainly rather have the tensioner a tad "too low", than a tad "too high". "Too high" would mean that you won't have 360° rotation (which invites a host of other problems, see my video below).

I recall that Wise had an adapter for some Gamma machines.

Yes, that's true.
However, the so-called "Gamma adapter" was/is only for (potential) use with Gamma crank/LO machines (furthermore, it wasn't - and still isn't - required).

Therefore, the "Gamma adapter" isn't relevant in regards to mounting the Wise 2086 on any drop-weight machine (even a Gamma DW).
There are a variety (different heights) of "drop-weight adapters" for mounting a Wise 2086 onto DW machines.

The "Gamma adapter" (which is solely for consideration with a Gamma crank/LO machine) was originally an option (i.e. "fix") to eliminate the string rubbing (pulling upwards), against the vertical front edges of the linear string gripper. This was long ago, when the Wise units did not incorporate a diabolo.

So, the "Gamma adapter" (if one were using it) would raise the height of the entire Wise 2086 unit (2 inches) so that the linear gripper would then be at the same level as the string bed (thus eliminating the "string rubbing" issue).

Later on, Wise units incorporated a diabolo (which, when used, also happens to eliminate the "string rubbing" issue), so even if one has a Gamma crank/LO machine you don't really need the so-called "Gamma adapter". In fact, using the "Gamma adapter" will still cause you to lose 360° rotation.

With the diabolo now being standard on the Wise 2086 (for many many years now), you get to have your cake and eat it too.
There's no "string rubbing" issue to be concerned about, yet you still get to have/maintain 360° rotation (plus, you don't have to buy an additional $45.00 item). :cool:

Measured the bolt pattern in case it's helpful to anyone. M8 bolts were measured by eyeball and digital calipers. They ended up with pretty round measurements. The M6 bolts did not, so I gave my best guess.
