Yup, got it, thanks!

The big model erinco linked looks ideal.

Man, step away for a few weeks and PSA goes crazy with announcements!

1) I never met or spoke to Jim, but I certainly do appreciate all the work he has done over the years. Best of luck Jim, it’s been a pleasure experiencing your PSA products!

2) New low turned ported sub, can’t wait to see what this beast can do! I love when PSA throws their hat into the ring on flagship products, they are often imaginative and unique (Triax, s7201). Time to grab the measuring tape...

I’m curious how the low bass will be with these high end PA style drivers. Midbass will destroy both my s3601s together I’d bet

Regards,

Sorry Mike, I don't know why I didn't include your full quote in trying to make my point that ULF TR would be increased with the new LT sub "irrespective of distance".....especially since @Chuck 0 is happy with the TR with stacked V18s now........

Hello Randy my friend, good to see you back, it doesn't take long to miss something here as things are just moving at high speeds..............Jim is and will be missed by me personally for a long time to come, he is my friend.......

I'm confident Tom will continue the tradition of top QC and CS that is the benchmark of Power Sound Audio, I don't believe he knows any other way........

Having had both the original Triax and the 7201 in my home it seems the only thing to do is make it 3 out of 3 with the next Flagship......I'm not Meatloaf with 2 out of 3 ain't bad.......
I'll be in touch and hopefully we can talk, it's been too long buddy...

BUT...it can goto into "freeze" mode when pushed. And for whatever reason multiple chats open simultaneously really seems to bog it down.

So I'll be upgrading as soon as I find time to research a solid replacement.

And please don't rely on any forum "pm" to reach me in a timely fashion. I sometimes see those, sometimes not. Email is always best.

I know there is a lot of speculation about the new low tuned sub(s), here's mine.

My guess is that it will be similar to a JTR2400ULF/FV25HP down low; a little better if IPAL's are used, similar if the standard Neo's are used. Above 40 Hz these things will be insane and I wouldn't be surprised if they end up with class leading mid and upper bass output with the lowest distortion of any ID or retail offering.

IPALS's have 20mm xmax, so 40mm for a pair.
Standard Neo's have 16.5 for 33 combined.

If that’s the case, he’ll yeah. Is a 1920 rms module enough though for a a 2 ohm ipal speaker? Are they able to deliver more power and a lower load?Surely those are gonna need about twice the power per speaker. I wonder what he has up his sleeve

Well, actually, with 97/98 db sensitivity, you don't need as much power to get crazy loud. Also, those amps have great burst output, higher than the Speakerpower 2400 watt units. Is it enough to get every bit of performance the IPAL's are cable of? Dunno, maybe its good enough. You don't need as much power down low with a ported setup, and with the efficiency a pair of those neo 18's will have up top....4300 watts of burst power should make some noise.

Bear you beat me to the punch in answering DC's question especially with the sensitivity and power to drive the iPALs... the new 1920 amps are incredible, I don't know what PSA did since bringing them in house but it was noticeable to me right away for the better...the only way I know they're on besides the green LED is the soft relay click, absolutely dead black quiet.....

You'd need quite a few Triax's stacked to compete with the 7201....different ballpark

Except no one will know for sure since there will be no independent testing. Which would be a shame.

I'm packing one of my V3611s right now and paying for overnight shipping just so Shady J can review and test it for me cause without his validation I might as well just give both of them away now......

I finally got my Umik mic and got REW up and running. This app is so cool and found it relatively easy to use when following the guides available from many of you.

Ran some measures and got the results after moving the V1510 all over my room ended up the best response was where I started...lol

Attached a couple graphs for you guys to comment. I ran a comparison of No Audyssey vs Audyssey Reference vs Aud+DEQ and wow DEQ really bumps things up. Anyway let me know what you think and if it looks like I did things right.

In a couple of locations I got huge dips but luckily I dont have anything like that in my best spot. Next up I will run compression tests.

looks good. The house curve with DEQ looks crazy +15db . if it were me, i would use "Aud Ref" or "No Aud". or get a minidsp and make your own EQ.
why is the "no aud" starting to climb at the 95hz? are you running this with another speaker, or was this sub only?

and no need to Avgerage them in the future.

I've been lurking in this thread more than ever with the recent announcement of these new ULF subs Tom will be introducing. This is going to be HUGE if PSA gets this right! The performance of JTR but with the customer service PSA is known for could seriously catapult Tom to another level. My only request is for Tom to really take his time with this new subwoofer and not be influenced by people that aren't patient. Getting the proper size cabinet, driver, amp, tuning point, port size, etc etc to marry well and meet everyone's expectations should NOT be rushed to market. Just my .02

Great post Darian. I too am more than excited to see PSA moving forward with new designs and constantly improving their current ones. With the past experience and proven tract record Tpm had with SVS designs and now with PSA's success, I have no doubt that he and his team have been fine tuning the new designs to the point that they will definitely set new standards for subs.

Good points, however this has been in the works longer then you think so I highly doubt there is any outside influence that would push PSA towards releasing a product prematurely.

Good to see you around too! It has been too long.

And yeah, I have zero doubt that Tom has this under control. I’m already looking forward to the rave reviews and overall excitement when people receive the subs... it’s gonna be a blast!

Thanks @Karami

Yeah those were with Center which pulled 70hz values up when compared with sub only no Audyssey. I also thought DEQ was nuts so going to turn that off. MiniDSP is on my wish list so house curve will be in the plans.

So ran compression tests today. Details below
UMIK - 18DB gain
Level set at 81 for Windows 10 as per REW guide
Running compression tests (attached) and on the last run I get the clipping warning popup
In the image I notice that there seems to be some compression around 13-14 hz but this is after the sub starts rolling off. Is this my compression point? If not how do I configure to get past the headroom limitation? Am I doing something wrong?
I also tried running the sweep from 17Hz and up and I still run into the clipping warning.

Any feedback would be great..thanks

This seems contradictory to what both @Hopinater and Tom posted just one month ago. Why would Hop dip his toe in other waters if the wheels were already in motion at PSA? He wouldn't have and he stated it that PSA had no such plans for the foreseeable future. I believe 3 significant factors contributed to the shift. @imureh 's sub comparison thread, BassEQ, and Hop.

Or were you just alluding to PSA leveraging previous, proven designs (SVS 16-46+ & PSA XV30FSE)? This factor gets my full confidence.

It was more then a month ago and PSA has been prototyping different designs for awhile.

In the image I notice that there seems to be some compression around 13-14 hz but this is after the sub starts rolling off. Is this my compression point?
It appears that this is your compression point as you only saw a 1.8dB average rise (unless you only increased the signal level +2 dBFS). You should still set your UMIK gain to 12dB or 6dB IMO.

How loud to do you normally listen (main volume)? How hot do you run your LFE?

and to add to it, we were discussing this low tuned stuff this past fall. I believe the "no plans" was to keep pressure at bay from customers flooding phone, chat and emails with questions. The main priority was bringing things in house before expanding, then Jim leaving added further delay.

I understand not alerting the forum. But why not alert Hop?

I tried to alert Hop and other members via PM when I knew it was happening for sure.

So ran compression tests today. Details below
UMIK - 18DB gain

In the image I notice that there seems to be some compression around 13-14 hz but this is after the sub starts rolling off. Is this my compression point? If not how do I configure to get past the headroom limitation? Am I doing something wrong?
I also tried running the sweep from 17Hz and up and I still run into the clipping warning.

Any feedback would be great..thanks
its either your sub hitting it's compression limits or you mic cliping.
here is a walk through that help your mic https://www.avsforum.com/forum/155-d...-umik-1-a.html

also can you should run the sub only and not with another speaker, it will give a ture reading about your sub.
