For some time now, based on info I've read and on input from guys like bear123 (thanks, bear! smile.gif ), I've been increasingly-seriously contemplating replacing my two Chase SS-18.1s (SS-18s) with dual PSA XV15se's (XV15s). Everything about the XV15s indicates that they're kick-@ss subs, and given that I have a fairly large room (a little over 3,400 cu.ft.), ported subs should work better than sealed.

But there are a couple of things I'm still not clear on and I hope to get some clarification.
___________________________

1. In my room, my old PB12-NSD - which was rated to 18Hz @ -3dB - rolled off pretty hard at ~17-18Hz and my current SS-18s (with PEQ applied to boost the bottom end) roll off pretty hard at ~17Hz. IOW, I don't think I have any room gain at all. (I sometimes think I have "room suck-out" below ~17Hz.)

The XV15s are rated to 21Hz @ -3dB and the advertised 15-18Hz in-room extension is premised on room gain...which, it seems to me, I don't have.

Questions:
- Given the 21Hz rating of the XV15s and the fact that I have no room gain, can I realistically expect useful sub-20Hz performance from the XV15s in my space?
- If 'yes', would it realistically be any better at ~17Hz than what I'm already getting from my SS-18s?
- Or, to put it another way, how much louder (in dB) would it have to be at 17Hz to make it worth the upgrade?
___________________________

2. The recent data-bass.com testing of the SS-18 seems to indicate that it outperforms the previous-gen XV15 (which, according to Tom V., was not that much different from the current version) on a number of fronts:
- Max Burst: The SS-18 surpasses the XV15 from 40Hz and up, and at 20Hz is only 4dB down.
- Basic Response and Full Range Response: The SS-18 surpasses the XV15 at every point on both FR curves.
- Maximum Long Term Output: The SS-18 beats the XV15 down to ~25Hz, after which the FR curves are intertwined.

IOW, I'm not seeing the advantage of the XV15.

(NOTE: In case it makes any difference, I never listen at reference. Regular listening is at -18 to -16dB; bumped to around -14dB for quieter movies; and to around -10dB for demos.)

Questions:
- What am I missing here?
- Am I not reading the graphs correctly?
- What other factors do I need to take into consideration?

What are you looking for? You don't listen loud enough to maximize what you have so the only change needed would be extension. For that you need different sealed subs are a larger more powerful ported sub. I you are looking for more SPL than turn up what you have and see if they can handle it. It seems you want extension and getting another 20hz ported sub won't get you more extension than what you have already. You need something like a LLT or boost the low end more on sealed subs with a LT but make sure your subs can handle it. If not you need different sealed subs.

However, given that I really don't want to spend more than ~$2,500 CDN (all costs - shipping, exchange, taxes - included), I suspect it may not be possible.

So, the XV15 is not that "larger more powerful ported sub"? And a pair wouldn't provide that additional extension (or greater & flatter sub-20Hz output)? That's what I'm trying to figure out.

(I'm pretty sure a pair of them would deliver sufficient over-20Hz output.)

I was acutely aware of that as I was writing my post. wink.gif

-- Edit --
I should probably add that:
- I'm not interested in any other subs. The XV15s are the right size, weight, look and price, and by all accounts so far they deliver on performance. And PSA's warranty and CS rep are solid.
- DIY is not an option. I don't have the tools, the skill or the patience for it.

The XV15se will provide a noticeable increase in 18-30hz output. If your current subs are running out of headroom in that range then yes the SE has you covered. There is no point in comparing the original XV15 data, the SE is going to have much better long term power, lower thd, and much less compression. .

eljay you have the same problem that I have, a large room. Mines is 5,300 cu ft. so I know how hard it is to get room gain and extension. You need larger sealed subs, or some kick *$$ ported subs like the Rythmik FV 15 HP. You also need some type of DSP to help shape the under 20 Hz response like a mini DSP.

You need something that will be OK with the wife and the Rythmik come in nice finishes. They are over budget but, I can't think of a better ID sub combo for the price and looks. The SVS PB 13 Ultra would be a second choice. Most of the other subs just are not strong enough for that space. I had to go to 4 subs to get good extension/spl and use DSP/PEQ. That is the problems with large rooms, it is all on the sub and sub amps so you need power and a lot of displacement.

Above 40 Hz, you will probably lose a little bit of output. However, I can't imagine that you are ever even approaching the output limits that you currently have with music or upper bass. My single XS30 had much more output on music than I would ever use...my amp/mains gave up before the sub did...as in, it played clean, loud and unfaltering up to -5 or 0, but beyond that my mains/avr went into clipping an became very harsh. REW sweeps show major compression at a +5(from mains, likely due to AVR)

When I switched to the XV15, although it has less output than the XS30 over 40 Hz, it gave me the same effortless impression...with more headroom than I could use up to the -5 and 0 MV levels with no signs of running out of steam. And this was with just one. So I don't think you will notice any lack of output above 40 Hz, especially with duals.

What I think you will notice, will be a big improvement in the 16-30 Hz area for movies. Your current subs are tested to be @ 94 dB at 16 Hz and 98 dB at 20 Hz....from what I can tell, the XV15's should conservatively give you double the output in that region. Since they are ported, I think you will be very solid in this region even without a lot of room gain.

For me personally, on a 110 dB sweep, I am at 105 dB at 16Hz, then 110 dB at 20 Hz on out past crossover, tested from about 3m away from the subs.

If you listen at -15, and run the subs 5 dB hot, you are calling on your subs to reach peaks of 105 dB, perhaps higher with bass redirected from the other channels. And at -10 you should be hitting peaks of 110 dB. I would say you are falling quite short of this in the 16-25 Hz region. Have you tried doing sweeps starting at say....-15, then going up 5 at a time until you get compression? This should show you at what point you are running out of headroom.

Thanks, guys, for your replies.

derrickdj1: I'd love dual FV15HPs or PB13-Ultras, but I'm not prepared to spend that kind of money. If the XV15s can provide what I'm looking for, I'm there; if they won't show enough of an improvement over the SS-18s, I'm happy to stay with what I have.

basshead81 & bear123: I get that the XV15 *should* outperform the SS-18s below 20Hz, but I guess I'm having trouble visualizing the Data-Bass ground-plane FR curves as in-room FR curves, and seeing the XV15's 4dB advantage in the max output 16-20Hz range as significant. I know I must be missing something - can you guys tell me what?

Thanks again.

4db more headroom is 60% more output that is very significant. PSA testing revealed the XV15se laying down 108db 2m rms and within 1.5-2db of the FV15HP for most of the frequency range, it also is capable of 5db more output on the long term compression sweep. Of course the FV has more features, deeper extension capabilities and output below 20hz. However I disagree about the finish options that was mentioned. For 1249.00 you have 6 different furniture grade finish options with the XVse.

Edit* I just looked at the data-bass numbers and noticed you are still comparing to the original XV. The XV15se has a 3.1db gain in the 20-31hz average over the old version and is up almost 5db around 20hz. Take the time and look thru the PSA thread, I posted plenty of info there.

Eljay, have you thought about dual vtf15h's? In one port mode, those would extend deeper than the xvs and have a more gradual rolloff to tune (17hz).

The issue for you with the xvse is that they have a more steeper rolloff after 20hz even compared to the XV line, so you will likely not see extension to 17hz in your room. I wouldn't recommend boosting below tune, specifically in your room with no gain, as you open up a good possibility to driver damage.

If you really want to ensure you keep your extension, I think the vtfs would be a good fit or perhaps 3 lfm1-ex at their sales price. They have a 17hz tune as well.

the SE will still extend to 16hz just fine. It may not be +/-3db without some eq but it will still have more output then the original XV according to Tom V. Fyi the tune never changed(18hz) on the XVse, the dsp was changed. So some slight boosting around that frequency should not be a issue.

The XV15se is no doubt a solid performer. I just don't think it's much of a looker. Yes, it does have multiple finishes to choose from, but it just leaves a lot to be desired on the eyes. As long as you're happy with it and you can get it to pass the WAF then more power to you.

Specifically, I am only picking on the looks of the XS15 and XV15. I do realize that PSA's enclosure design probably cuts down on costs and that is part of the reason why they are able to offer such a great product at an affordable price.

Well I prefer the base plate version myself, but I am not sure how you consider the FV15 to be a "looker". Its just a big black box that does not even have rounded corners. I am by no means saying the FV15 is ugly just trying to relate to your post. Fwiw I believe the OP stated the looks were fine so not much else to discuss on this topic.

I just don't see the advantage of the ported PSA as it is not tuned low enough for more output down low. You won't be using everything these have at your levels so for deeper extension you need a deeper extending ported sub or a sealed sub with less rolloff. If you are not using everything your SS's have now try boosting the low end 3 dBs and see.

Based on what you mentioned about your room and the XVse rated number, I do not think you would gain much if any for what you are looking for. I would start saving or if you are close enough to jbrown, ask him to help you build a few subs.

^how would you know?

From my understanding Eljay was not looking for deeper extension he was looking for more output from 17hz on up. The XVse will get him that in the 16-30hz range. I find it funny all the anti-psa are in here recommending different subs when he specifically stated in post#4 that he was not interested in anything different.

Yea well I meant edges but anyhow the point is you are creating a strawman debate to derail the thread from the OP specified criteria. He specifically stated that he was not interested in any other subs and the XVse size and waf factor was fine. So unless you can comment about the extension on the XV15se or offer any further useful information you are derailing the thread. So yes lets please get back on topic.

Is he not running the subs at -15 dBsMV. If this is the case he just needs to raise the LFE trim 3-5 dBs since he is getting 17hz now. He might not have to change at all.


Can we see a response graph? Maybe we can help better.

Basshead,
He mentioned having a ported sub tuned to 18hz that rolls off at 18hz so if he gets a 21hz tuned sub he won't get 17hz based on his room, those graphs sure would be nice.

You're getting defensive and calling people out when nobody is bashing PSA. I'm not trying to push him to buy Rythmik subs or anything else for that matter. I quite often will recommend PSA when it's applicable. I simply said that the XS15 and XV15 aren't exactly super models. My subs are up front by the TV, so aesthetics are somewhat important to me. This is my opinion and not everyone else will share the same feeling.

How would I know? Based on what I said above your post. how do you know the XVse will get him more output at 17hz in his room? based on PSA posted FR: XV15se FR: 21Hz-200Hz +/-3dB (15Hz-18Hz typical in-room extension)
anti-psa? What? I often recommend PSA sub but just not for Eljay and I have not reccommended any sub in this thread. This is why some folks labeled you as PSA soldier.

If you are going to replace the CHTs with the PSAs and get rid of the CHTs, you'll take a good hit on selling the CHTs, too.

If you can deal with the aesthetics, the other option is to get two more CHTs and then collate them (with the drivers pointed out toward you and the feet sticking out--lol--although you could cut them off and paint over it). Then get an EQ to help smooth the response more if you think you need it. Also, you might consider this Dayton amp mod: http://www.seaton-sound-forum.com/po...de-amp-6176968

Or, have you considered ordering a couple of the flatpacks, some drivers, and another amp, and going with two more different sealed subs? That would be nice

Edit: I did get my Dayton amp modded. It definitely helps

I am getting to 16hz with no problems and have plenty of output. I will take another measurement with all three subs level matched. I found out i had my third sub set 2 notches higher on the gain which was limiting the output of my other 2 subs. Should easily do 113-115db @ 16hz. Eq the peak down and the graph would be relatively flat down to 16-17hz. (Take note the graph is no eq, ypao disabled, 80cross, subs only)

Tvoung, the only part of my post directed towards you was the "how do you know". I was not specifically calling you a anti-psa'er, hince why i did not quote you. Also take note folks I use emoticons to try and show I am not being defensive, harsh, or combative. Lets play nice its all fun here.

I took your ^^ as directed toward me. My point again was based on PSA rated FR and Eljay's room, replacing his SS18's with XVse's might/will not be an upgrade for him. Just because the XV15se's do well in your room does not mean it will in Eljay's as he mentioned with his PB12 (rated -3db @18Hz) 17Hz roll off at his place. Do you think the XVse rated -3db @21hz would do him any good for what he is looking for in his room which actually his question. I have been nice and trying to be helpful here
