I just find it strange because I've listened to other bass heavy movies at higher volume and never had a problem. I turned the gain down hopefully never heared that sound again.


Most likely the receiver sent an unusually large voltage spike(a sudden bass peak) to the input on the XV15 amplifier. So it may have had a very brief (fraction of a second) "clip". This often sounds like a "clack". The driver cannot "bottom" and make this type of noise in our designs.

Have you calibrated yet? If not, that tends to help minimize this type of problem. If it only happens "once a month" or something like that I wouldn't worry too much about it. If its more like once a day....time to calibrate and or try a different location for the subwoofer too.

Yes I calibrated the system with audyssey xt. The xv 15 has been sounding great. This is the first time I've heared it make the clack sound. I just wanted to make sure I wasn't doing anything wrong. Thanks for the quick response.

Hey Tom...This brings up a good point.
Are we safe to assume that for the most part the DSP in the amp will prevent us from damaging the sub by pushing it too hard. EG, turning up the gain too much to get more spl.?

Short answer, yes.

Please don't take this as a challenge but it would be *very* difficult to damage any of our products under normal operating conditions. This means typical source material (not steady state test tones) with SOME semblance of proper setup/calibration. And of course I'm also assuming the listening environment isn't ridiculously over sized for the product. For example, you can have a single XV15 calibrated.....but if its in a 25,000 cu-ft area 10 meters from the seat. It may just throw up the white flag before long.

Also, the DSP front end on the amplifier serves many purposes during the engineering process. It's more accurate to think of the entire system "synergy" preventing damage. Get the driver or enclosure/ enclosure tuning, a little "wrong" and no amount of signal processing upstream will save you when the going gets tough..smile.gif

I'm gonna write a full review probably tomorrow when I get on my computer. I'm usually posting on here with my phone. But I'll give you my first impression.....this thing scares the s**t out of me!

Going between 2-channel stereo, and "Pure Direct" (No subwoofer) on my Yamaha. Its incredible what these subwoofers add to the mix. They bring an atmosphere to Tom Waits that i only ever got from headphones. Happy owner.

Can any XS-30 owners give me your impressions on this sub?
im considering buying one within the next few weeks.
i just sold my 2 rw-12d's klipsch subs and im still researching

To preserve the intimate nature of Tom Waits, in my opinion, one needs headphones. Just saying, short of live, I don't think "any" Home Theater/Music system will do Tom's recordings justice.

I live near this route; Yuba City, Live Oak, Gridley and Chico. Yuba City grew up. Marysville tries, Live Oak and Gridley have tried to grow and continue to hang by the side of the road on a Walnut grove tree branch with 99 going up the middle and without Chico State, Chico would be the same, hanging by a rice hull husk. And North of Chico, into the dark, the road rolls onto more of the same.......Los Molinos. cool.gif

Hammer, to be more helpful to you, is there anything specifically you would like to know? We could all tell you we love our XS30's but if you have any specifics just as your listening habits, what you want to get out of the sub we can probably be more of assistance. It probably wouldn't hurt to get a hold of member SmokenAshes, he returned the XS30 and went with the XV30. Might get his take on it as well. I upgraded from the JBL sub 12, to the XV-15, to the XS30. Very happy with the upgrades! You are coming from duals...are you going to continue with duals? I know a lot of the members with duals have been more than happy!

the subs will be used for music and movies equally
the subs i sold just didnt have the deep clean bass i was looking for
and yes im going to go with duals
I also read a nice review on the XS-30 http://www.hometheatershack.com/forums/home-audio-subwoofers/64133-power-sound-audio-xs30-first-impressions.html#axzz2JxsUt6me


I wish some of the PSA owners would post some videos on youtube, there's nothing

Brian, i purchased the XS30 more to future proof as its in a fairly small room right now. I definitely notice a difference, however, I had my XV-15 in a bad spot as my listening position was in a null. I moved my XS30 right next to the couch and it is earth shattering. Had the XS30 not come out within 30 days of the purchase of my XV15, I still would have been completely satisfied with the XV15. I think the XS30 is a little more discrete because its an inch shorter. The lows are about the same but there is definitely a kick to the mid bass and that was my reasoning for purchasing. I figured most of the lfe content is in the mid bass range so why not go for the XS30.

Would you say the XS30 has more mid-bass slam than 2 XS15s? I know you have no way to compare, but I'm curious as I'm thinking of adding an XS30 to my 2 XS15s. cool.gif

Personally, I believe an opposed, dual, 15" driver based XS30 would be a perfectly delightful add to your system.

What specifically were you looking for in the video? Just an overall overview or you want to see things shaking and rattling...
