So it does good with movies? Everybody always says ported is the way to go for movie watching and sealed subs are better for music. So is this what you've observed? That's the reason I went with the xv15 vs the XS15.

I find the xs30 is much better all around. My toom is open but not huge either the entire room is approx 30x17x8. With the listening area only 14x17x8. And it has no problem with movies at ref.

I think if the room were much bigger and it was not corner loaded the ported might suit me better. But thats not the case

Agreed as this comment was what I responded to: "That's why I wasn't sure if a sealed sub could work out, with out having to buy a triax!"

Again, agreeing with you, that's why I suggested it's an intrinsic thing as based on the above, I didn't feel comfortable saying, buy two Triax subwoofers with a possible eye on a third in the near future. biggrin.gif

The ULF thread opened my eyes as to what's what with what regarding intrinsic details. Above a four star system and the individual is in the wonderful world of esoteric. If one is wanting to pack their room with subwoofers, in the PSA line of subwoofers, three XS30s should work to get someone into the ballpark of where they're wanting to go.

Are the Power Sound Audio sub amps made in the U.S.A. (nothing is listed under Amplifier Specifications)? Are the amps UL listed?

Well I got my new dual XV15s setup this weekend and I am very pleased with the performance of these fine subs. When I set the first one of them up, I was really disappointed with the sound and overall output of the bass so I knew something must be wrong with my 2800 cft room or the way I was setting things up.

I tried moving the sub to other places like the front of the room but that did not help and I even did the sub crawl test again which pointed me to the original spot of my SVS PB12-plus, just to the right of my couch. I listened to my favorite MC music and something was still not right. It just didn't sound like my old sub.

I was about to email support at PSA when I remembered that I have a couple of peaks and nulls between 30 and 50Hz. I had been able to smooth those out with the PEQ function in the SVS, but I knew the XV15 did not have this option. I then decided to setup the other sub to see if that would help with the sound and that did the trick. I went with a mid side wall location.

Wow! The sound is much improved now with plenty of output and the response sounds smooth overall with good definition in the bass. I have each sub level balanced and the gain set to around 3 oclock for each sub and I got about a 4.5db increase with the combined subs. I then had to turn down the level in my Oppo player to match the main speakers.

I am using analog connections because music sounds so much better to me with my Oppo 105 and this configuration. I also use the analog for movies as well and the results are very nice. I tried some of my favorites MC sacd and dvd audio discs like Steely Dan's Gaucho and Donald Fagen's Morph the Cat. It sounds excellent and I also tried out a couple of blurays like LOTR FOTR opening scene. I get great extension in the bass and Star Trek-Into Darkness opening scene was very good also.

Thank you to Tom and Jim at PSA for making such excellent subs, and I am glad I decided to go the dual route with subs. It was worth the time and effort in selling my old SVS sub which was excellent as well. Glad to be a part of the PSA family now.smile.gif SDC11132.jpg 931k .jpg file SDC11133.jpg 791k .jpg file

Welcome to the family!! Glad your enjoying them. I must admit seeing the xv15 without a base is weird for me haha
post #7236 of 9895
Those XV-15s look so lonely now without their original base wink.gif. I think that is the first in house picture I have seen since they opted to go without the bass. Regardless, I wouldn't hesitate to buy again, I just hate change!

No almost every plate amp is from the land of pollution. Now the Triax sports a speaker power amp that is manufactured in the USA.

Thanks Brian. I really like what I hearing so far with the XV15s. Not having the base plate made it a bit easier to move the subs around since the weight is less now.

Most people probably won't need more than 2 Triax's unless they have a very large room. Or are insane for bass.

The BASH amps (all the subs in the power x line use these) are designed in Canada and I think built in China. The Amplifier in the Triax is built in the United States. Sadly I don't know of any plate amp manufactures expect Speaker Power (the designer of the amplifier in the Triax) that build and offer USA based amps.

For overall heavy bass and slam factor, you can't top a Swedish band called, "Hideous Divinity," specifically the song, "The Servant's Speech." I'm a life long metal head. If you need more recommendations, I have enough to keep you busy until your next life time. PM me anytime

Thanks for those recommendations. I'm almost ashamed to say that I like the sound of Decapitated and Hideous Divinity a bit more than Gojra and Dethklok, which were mentioned previously. I say ashamed simply because of the band's names -- it reminds me of an old parody I saw long ago where a veejay was reviewing totally opaque metal bands, with gradually more disgusting names... It's actually amazing that we can instantly find out about those (relatively) obscure bands as soon as we hear from them just with a Youtube search biggrin.gif

Also, I haven't yet had the occasion to listen to that on my main setup. With my GF at home with our 2-months-old baby, it seems like opportunities to listen to metal in the living room are becoming really scarce. Still, while above average for metal, the bass content of all those suggestions is really not on par with, say, the last Nine Inch Nails or Daft Punk albums for example. In those, the dynamic range seems much better; even the non-synth parts seem to have great, profound bass in comparison.

Anyway, since it seems like my daily commute to work is the only place where I can play loud music that fit my tastes... anybody know if PSA will make a car sub soon? biggrin.gif By the way, I know this thread is really not the place for this, but I'm curious about what anyone here (i.e. experienced HT enthusiasts) have to say about car subs. I have none but I'm considering the option biggrin.gif

I'm strongly eyeing the XS30 but it appears it doesn't come with any sort of base to sit upon? For those of you that own this sub, do you think a) I would benefit from placing it on some type of riser, since it appears to sit flat on the floor (my room has wood laminate flooring), and b) if you use this sub with a riser/platform....what do you use? Thanks all.

Brian you keep updating your equipment list, any projector on your radar smile.gif? just ordered x4000 from AVS to replace x3000, how do you like the x4000?

I am also eyeing xs 30 to replace xv15 before my 30 day return date still, hoping the x4000 can care the port noise from the monument screen.

yea I have had a good run at poker...so I was able to make a bunch of upgrades....

The x4000 is AWESOME!! the xt32 is a HUGE upgrade over XT...i never thought it would be..and am mad I didnt make the switch earlier..

It's this type of talk that needs to outlawed.

If I'm correct, it already is as this type of talk is disruptive and comes under the heading of disturbing the peace. tongue.gif...biggrin.gif

My position, I'm financially close to being able to pull the trigger on a single or pair of FV15HPs but the AVR is in serious need of an upgrade so I can go from XT to XT32 and I can't do both.

More than likely, that will have to wait until my b-day next year. Boo-hoo me. biggrin.gif

was fiddling around with minidsp last night (now that I got the longer USB cord to make changes on the fly inreal time) and added a custom L/T filter...much flatter than the built in low shelf...that thing is awesome for only 100$ highly recommended.

so now I am +/- 4db down to about 8hz eek.gif

i am curious what it will do the headroom though...even though I know I dont need to max out the sub in my room

take a max spl sweep before and after with REW and you will know. 8hz extension looks great on paper, but how much output the sub can put out @ 8hz is more important.
post #7254 of 9895
how do you max spl sweep it?

Using the spl meter in REW, play a test tone, ( use the lowest frequency befor the response falls off +/-3db) turn it up until the sub will not get any louder, then back it down 3db and run a sweep with REW.

I hear ya there. Watched Man of Steel last night and wow! The clarity is shocking and the bass is plentiful.

Ordering XV30f #2 next week! I have to go through a few movies so that I can compare now vs. having both subs in the room.Curious to see what XT32+SubEQ HT can do with a pair of those monsters.

And using the MiniDSP, you can always boost the low-end and trade max output for extension. If you don't listen that loud it's actually a great idea, and the trade-off is easier to perform on sealed subs than on vented subs, where there isn't much one can do below the tuning.

That being said, to be perceptible, a 10 Hz waveform has to be played quite loud, especially if it's played with circa-20 Hz content.

Also it's interesting to stack up response curves taken, say, at 3 dB intervals. That way you can clearly see compression in the lower frequencies (typically due to the limiter).

By the way Brian, user Lecter83 just posted in the SVS owner's thread a pretty interesting graph showing the lower limits of human perception for ultra low bass, allegedly according to an obscure standard:



I would take that with a grain of salt as the only other place where I saw a DIN standard was in Paradigm's specs rolleyes.gif and the curve is suspiciously linear... But if it's reasonably accurate, that means that for a 8 Hz waveform to be noticeable, you'd have to reach north of 100 dB SPL, whereas 20 Hz requires only about 72 dB SPL.

Good news. The people in the control booth, have taken the above into consideration when they tracked the sound track.

As long as you're flat, you're golden.
