That's actually a good question I think. I don't have this problem really but with two 4kW subs what do you guys do? Are they on 15A circuits? I guess you use two separate 15A circuits? Each will have a max RMS power of 1800W; that is well below the RMS rating of the Triax' amp. That being said, in audio it's mostly transients and the circuit can provide much higher peaks.

So do you plan on upgrading to dual 20A circuits?

Wow I have an 818 too and didn't even know that ajusting the trim levels in the options was only temporary. This is awesome, thanks.

Good luck with that... some rattles are rather easy to tame but I think the ones in my room are caused by the air ducts in the (finished) ceiling. Fixing that would be... complex.

Thanks for the great advice Tom. I think I like the idea of what we talked about earlier.... getting a single XS30se now and then later on, possibly getting another. An XS30se's dimensions are only slightly larger than the XV15, however, I think the footprint would be less because I wouldn't have to make room for the port.

I am reading Jerry's guide and as I read farther I saw that the ASIO drivers were needed for the HDMI. Thanks for the links Jeff, much appreciated.

The performance of a single XS30se will be similar to dual XS15se. The main advantage for the dual XS15se would be the potential for smoothing room induced peaks/dips. The main advantage for the single XS30se is it leaves you an easy upgrade path....just add a second.

That sounds like fun, however, I am wondering why you would chose to compare the PC-12 plus (which is ported I believe) against a sealed subwoofer design?

I think it'd be an interesting comparison to check out the SB13-ultra and the XS30se.

Similar price and don't forget the PC-12+ can be sealed. Also want to compare sealed vs ported in my room.

Oh I see that makes sense. I didn't know that the PC-12 could be sealed. That sounds like a neat idea... would be interested in hearing your impressions on the both of them. My initial thought is that the SVS will likely create more output and probably will have a smoother bass response.

A more likely result is the same bass response, since that is primarily dictated by the room. I have had PB2000, a XS30, and an XV15se in my room, and the FR is the same for all of them except for different roll offs below 25 Hz. And I would say that the XS30se would have more output, except maybe around a small window near port tune.

Nice...I recently had the pleasure of comparing my XS30 alongside a SB13U...since then....I traded up to the "SE" drivers. Another member did an excellent write up comparing the same subs....we shared a few email exchanges but that review was instrumental in aiding my final decision. I will say this... though.... the new "SE" would have made my decision a lot easier....lol.

I liked both very much but for different reason...the new XS30se is certainly one fine sub.

Ha...I believe a local guy(acquaintance) was looking to go with dual XS30se from his PB12 plus...I wonder if he has taken shipment yet? I know TV is not at liberty to say, I might need to give him a shout(Steve that is)...to see whats up.

Anyhow if you do compare both..I'd love to read your thoughts...here is the review I was alluding to earlier...

Sealed up the PC+ isn't going to add much to a XS30se. Look at how the output capabilities of the PB13ultra were squashed when put in sealed mode.


http://www.data-bass.com/data?page=system&id=55

Then use the "system measurement comparison" dropdown and select XS15se. You can see the XS15se is a bit smoother/flatter and has more clean output. That is $799 vs. $1999(?)..

Now, figure the PCplus being what 2-3-4dB under the Ultra version? Let's just use 3dB. So on average the PC+ is 3dB under the Ultra which is about 1(?) dB under the XS15se. That puts the PC+ about 4dB under the XS15se. The XS15se is about 4.5-5.0dB under the XS30se.

So....that puts the PC+ about 9dB under the XS30se on average from 16-100hz with the PC+ in sealed mode.

You might see a 1-2dB increase best case but the PC+ would be running out of headroom so much sooner. If you try this, putting the PC+ closer to the key seating should work best.

Match a XS30se with another XS30se...and you'll be much better off in my biased opinion.

This might be the wrong place to ask this, but does anyone have experience with having their sub's on a concrete floor in a basement? I am planning on building a dedicated theater room in my basement and am really worried about losing that tactile feel of my XS30. I am planning on getting another one down the road.

Thoughts, suggestions??? Thanks fellow bassheads!

Not sure what you were on previously, but if you are worried about losing tactile feel you could always build a suspended floor and you'll likely have more than ever before

My XS30SEs are on carpet over concrete with no ill effects, I did make feet for them that raised them about 2" off the floor but I don't think it has any effect except I can move them around a lot easier as there are sliders under the feet. I think a lot of us have the same conditions with no problems.

I'm in a bonus room above a garage right now. That is a great idea but my basement ceiling height in only 7 1/2" feet, and that is concrete to floor joists. I also plan on doing 2 layers up 5/8's drywall with channel and clips, so that's going to chew up some room by itself.

Thanks Jeff, don't you have like 900 subs though....

I have 1 (yes ONE) XS30. Although I hope to add a XS30se....on that topic, would they blend well together or should I plan to upgrade the existing to a se also?

Going from a room over a garage to a concrete bunker....yeah, you're gonna lose a ton of tactile feel. You can build a suspended floor like Fatty suggested (only really need an inch or two) to get it back in spades.

Or there's always transducers....or more subs.

my living room floor is a concrete slab with carpet. I get awesome tactile sensation with nearfield placement. I just posted a few pages back of my subs producing a 7.2 reading on the vibrometer app.

you DEFINTIELY lose tachtile feel I went from suspended living room floor with my dual xs30's to a basement...and the tactile feel is gone. (well diminished quite a bit) I even put noe near feild, and it ws disappointing. SO I bought a buttkicker...helped a bunch...

I wilol build a very low platform to get the feeling back once I complete my HT down there

Panasonic 65VT30 | Panasonic AE8000 HD PJ | Denon x4100 ATMOS 5.2.4| Emotiva XPA-5 | PSA MT110 x 3 FL/C/FR | PSB B4's | DUAL PSA XS30 | OPPO 103 | minidsp | Buttkicker LFE

Non SE and SE products will perform very well together. The non SE won't have quite the headroom or
composure as you near the performance limits however.

Then use the "system measurement comparison" dropdown and select XS15se. You can see the XS15se is a bit smoother/flatter and has more clean output. That is $799 vs. $1999(?)..

Now, figure the PCplus being what 2-3-4dB under the Ultra version? Let's just use 3dB. So on average the PC+ is 3dB under the Ultra which is about 1(?) dB under the XS15se. That puts the PC+ about 4dB under the XS15se. The XS15se is about 4.5-5.0dB under the XS30se.

So....that puts the PC+ about 9dB under the XS30se on average from 16-100hz with the PC+ in sealed mode.

You might see a 1-2dB increase best case but the PC+ would be running out of headroom so much sooner. If you try this, putting the PC+ closer to the key seating should work best.

Match a XS30se with another XS30se...and you'll be much better off in my biased opinion.

Great information, thanks! I see in that comparison they compared the NON-se version to the SB-13U and found the music capability to be not as good. Am I safe to assume that comparing the XS30SE to the PC-12 Plus, they would be closer in music performance?
