Well done Jeff, very nice. I'll tell Jim we just hired our in house speaker stand designer..

Great work Jeff, those stands look great. Can't wait to see some mtm 210's proudly displayed on them.

Did anyone REALLY believe our solution to reduce the Triax weight would be to use the original power-x drivers?..

We bench check each driver before assembly so those were likely bench checked then placed near the power-x subwoofers to be assembled that day.

You know we're dying to know how the weight reduction was achieved. . Spill it!

He mentioned it in the speaker thread, same drivers and amp. The only change was with creative bracing to allow things to get lightened up.

I am curious to hear of what changes were made to the cabs? My guess is Jim was reading some ancient chinese architecture books and figured out how to build super structures with chop sticks.

Wow, they knocked off 75 lbs in bracing alone? Would love to know the details.

That's the rumor...

Weren't the original drivers a last minute replacement because of supplier failed to deliver? They are probably overkill for the Triax.

Easy. The Triax is a sealed sub right? They fill the enclosure with helium.

Or perhaps they removed all bracing and just pressurized the enclosure to add rigidity. Those driver can work hard anyway

Another theory: there's a down-firing driver now and it's powerful enough to provide 75 lbs of thrust.

Yeah once again my reaction is "overkill, what the heck is that"


There's no such thing IMHO when you're trying to get that kind of performance from your flagship sub.

The actual stands are 22.5" tall, with the feet you can add 1-3" of height to the stand. The 210s which will be used on these stands will place the middle of the horn at ear level, my chair places my ears at about 37" so I will adjust the stands to be approx. 23-24" because the middle of the horn on the 210 is exactly 14" from the bottom of speaker cab, this will place my ears exactly at the 37" mark which is the middle of the horn.. If you were to build these it is reco'd to make them about 24", but I added the option to make them 22.5"-25.5" . Thanks for asking my friend.

WOW thats all I have to say about this product. Just got my pair of xv-15se in and with just strictly plug and play (zero placement, calibration, ect) they are rocking my world. Cant wait to get it all set up but just plopping them on the floor setting amp to 80hz, and the amp gain to -1 and the sub gain to about 2:00 and the output over my PB2000 is crazy. I have room for a sub on the back wall and now Iam eyeing up the xv30F-se as size and looks play no role in that location. God Iam addicted to clean tight bass. On a side note .... It's not piano black but I love the finish.

I figured he just quit feeding the Triax other subs for breakfast, but what do I know?

Congratulations on your new subs. I hear what you're saying about getting addicted to that bass, it's pretty incredible. It's audio crack.

Here is a quick shot of the revised Triax. Looks pretty much the same except for the grill change. I'll try to get a shot of the bracing later today.
