That is true, the original Triax desgin was supposed to only weigh 190 pounds

Ray, do you think they will still get that slam factor with the 18"s that the 15"s give with the heavier driver? The 15s were at least 45+ pounds a piece, I remember

I would think so, with the bigger surface area the 18's wouldn't have to work as hard.

I'll have to come over and check them out when you get them

Hey Jeffery could you at least get the subs setup and run REW this time around?

Also Tom mentioned the difference is subtle...

I would not be surprised if Tom is "downplaying" the "subtle" difference.

God, the old days. They were the most fun in a LOT of ways. We would get 12 drivers at a time from FRC(?) all shipped fedex ground. Amps from some place called Something something Akustics? Like 230 watts? I think I still have a shelf full of those in the home shop. I remember now...RCM Akustics!

I think the first 6(?) months was passive only. But we never really sold much until the powered models came out. Of course we had some of the competition insisting the *PC* models would never last because the amp mount compromised the cylinder integrity. Um.....15 years later?

I remember the first two subs(16-46s) we shipped got to the guy in pieces. We had no idea how to properly pack anything. God that was disappointing. Serial number 1 and 2! I can't remember his name but I do remember they were going into his bedroom and he was VERY cool about the damage.

I swear I could write a book FILLED with anecdotes about stuff like this.

haha...i bought the baby 25-31 cs at first then quickly upgraded to the 20-36cs+ that was tunable to 16hz

I remember seeing people with 2 of them (duals was not really a common thing nor known to smooth response) and thinking they were absolute mad!

mind you I was still living with my parents in a 11x11 bedroom lol and it was corner loaded nearfield....so the response must have been sweet!

Cheers Jeff
Three primary reasons for the revision.

1)We are now able to source the Triax drivers from Eminence. So we have a very reliable logistics chain with significantly shorter lead times.

2)Weight savings as the new 18 driver motors don't need significant amounts of "steel" to be able to move significant amounts of air. Factor in the much larger cut-outs on three baffles of the enclosure and some other tweaks and we have the weight down to the 158 range(no grills). This should be a bit easier to move into place for our customers.

3)Subtle performance benefits

The 18s have something like 40% more surface area.

So the overall enclosure size for the Triax will stay exactly the same?

It will have to grow for the T-21 though

Also, still awaiting the first PSA 15" cylinder

Tom feel free to send me one and I'll test out it's weight. I'll be happy to move it into place in my house and let you know how it goes.

Correct, same overall dimensions. No plans on 21s. No comment on anything else..

Very cool Jeff. Looks like you have A LOT to look forward to. And we have a lot of feedback and impressions to get from you once all your new gear comes in.

Congrats and remember to keep moving and ducking, it'll be much harder for your wife to hit a moving target.

Jeff, I wish I could be more like you. Your enthusiasm for this stuff is incredible, and also contagious. I'm not even the target audience for the Triax and I find myself trying to figure out how to get a pair bc of you haha.

I think PSA should put you on the payroll already my friend

I bought one of the early 20-39s and then upgraded to a pair of 20-39 pluses as soon as they became available, driven by a Samson S1000. Subs number 35 & 36 IIRC. I still have them and they are still going strong.
