Which is really crazy
Lol that is insane...hey did you get any new measurements up yet?

Well, my take on it would be like this: If you upgrade all four XV15se's to XV30se's for an additional $2400, you will add 3 dB of maximum headroom. Does that sound like a good value to you? Going from four XV15's to three XV30's would only have cost $1,800 more, but would be a 2ish dB increase?

What do you think?

No, I spent most of the time hanging with the family. I coach my sons baseball team so that kept me really busy this weekend too. I'm hoping to get some free time this coming Sunday.

thanks for the link ..


is it possible to have too much sub woofer output in your room Jeffrey? looks like you didn't deviate from your plan too far.. just need number 5 and 6 .. I read some stuff on another site
someone had 8....

The overall sound quality between the XV15se and the XV30Fse will be very similar. The main performance difference is the extra output of the XV30Fse which isn't dramatic...something like 2.5 to 3.5dB over most of the operating bandwidth. Whether you have four XV15se or three(or two?) XV30se in the room I'm guessing headroom won't be an issue. And in most cases four subs will provide more of a smoothing effect than 2 or 3 subs. So just based on performance, the four XV15se would seem to be equal if not slightly above any XV30Fse option you might have considered?

Don't drive yourself crazy. Kick back and enjoy a new DVD..

What do you think?
4 versus 4, yeah about 2.5 to 3.5.

4 versus 3, about 1dB or so.

I'm not sure if the extra headroom would be beneficial in either scenario. You would have to pushing the limits of quad XV15se which would be difficult in a 3000 cu-ft room.

Thanks Tom, Bass, Mike and Bear for the reality check, sometimes I just lose my mind and start thinking, my first mistake. Tom wait till I have all four XV15SEs dialed in with PSA's new speakers..................

@ Ahblaza, I think you have/will have a pretty ideal setup. Some reading I have done indicates that four subwoofers is about as good as it gets for the smoothest frequency response you can get throughout an entire room. And you should have above reference level output capability down to 15-16 Hz. Not bad for what you have in it.

Why 3dB? If you double the drivers and co-locate them, don't you get 6dB more output?

double the displacement is 3db. Double the displacement and power is 6db.

My XV15's have yet to move at output levels north of 125db. Bass waves are omni-directional, so driver orientation does not make much difference. However a downfiring sub can help mask upper harmonics from higher crossover settings since frequencies above 100hz start to become directional.

When I had the xv15 I never had any movement of the sub...

you can place the xs30 any way you want in a corner...I have mine with the drivers facing the side wall and the console.

but technically my sub is setup sideways...the subs are "supposed" to be front and rear firing, but it doesn't matter one bit

Dual XS30's

Now that my dual XS30's are set up properly in my 12.5' x 17.5' x 8' dedicated HT (with lots of conversations with Tom V), all as I can say is WOW!!! Too bad these are not SE's, however the performance for music listening and BD movies and Concerts is incredible.

Thanks again PSA Team for designing/mfg such affordable products with this type of performance!

PSA provided me with cheap little foam tabs to put under the hard rubber feet for my XV15's as I am on hardwood. I have not noticed my subs moving, but they are definitely not inert like the dual opposed XS30....you can't even tell those things are playing when you touch them.....at least by feeling the cab.

Bear, wouldn't the rubber feet under the XV15SEs keep them in place on a hard floor, I may have to place one of my four on a tile floor over concrete section of my room, that's why I ask about the rubber feet, I was told that the plastic pads are for use on hard surfaces, my other subs on carpet haven't walked a fraction of a inch. I'm going to post some pics of my room and ask for suggestions of where to place the rear two XV15SEs. TIA

The first is a photo from behind the MLP, the others were taken from the front of the MLP and those are my rear placement options. I was thinking of stacking two of them against the back wall where that Rack is sitting, that would place them about the same distance of my front two to the MLP, or I could put them to the far R&L where the dehumidifier is on the right and the night stand on the left with the ports firing towards the rear wall about 7' from it and about7-8 feet to the MLP. Other option, move the big chair on the left and place them on either side of that putting them about 4-5' from rear wall. What do you guys think, I'm really leaning towards stacking them against back wall, this way they will be almost the same distance with the front two to the MLP. I would really appreciate all input, thanks Guys.
Cheers Jeff

Disregard the clutter, I'm going to change the front of the room and tidy up all the wires and do something with the ET stand. I'm making new stands as well for the new PSA speakers I'm still waiting on the fourth XV15SE to get here.

Talked to Tom last night about getting an XV15se and finally sealed the deal with him late this morning. Coming from a PL-200 I'm pretty excited to see what kind of performance one of these subs will give me. If it turns out as well as I hope, I may end up buying another one next year!

The XV15 is built just as well as the XS30. The difference is the XS30 is dual opposed which cancels out cabinet vibrations.

Correct the difference is due to driver configuration, not in the quality of the enclosure.

Please post up your results. I'm looking at the exact same swap, just waiting for the money to catch up. From everything I've read here, you're in for a treat!
