Upstart home audio company Power Sound Audio’s entry into the internet direct subwoofer arena a few months ago with the PowerX line of subwoofers has been accompanied by lots of speculation and excitement. Their middle model in the PowerX line, the XV15 subwoofer, is a large 15” down firing vented unit weighing in at a substantial 92lbs, with a 500 watt class D BASH amplifier, heavily flared Aero-port, black sand textured finish, heavy duty U.S. made driver and a 5 year comprehensive warranty. Additionally the PowerX line is assembled in the U.S. from U.S. made components with the exception of the amplifier. Somehow the price for the XV15 is held to just $799 and that includes shipping. We found that the XV15 sounded clean, composed and dynamic with music, while possessing extension well below 20Hz in room with plenty of headroom to make its presence felt in a large space on movie night. Even more important than the impressive parts list of the XV15 is the manner in which those parts are tuned to work together in a well rounded finished system. Highly recommended.

Yeah… the standard finish is quite nice, I've seen it in person….much nicer IMHO than the traditional flat or faux black finish you often get on competitors products. Curious to hear read your thoughts once you have it all set up.

Just a FYI, we can send out samples of the wood veneer AND the Black Satin free of charge. Just send me a note to one of our email boxed.

Unboxing the XS15se

Well I got the sub (very fast shipping BTW!) Here are some photos of the unboxing. While it was not double boxed it seems to have travelled well.

That would be the gentleman in the above post TV…IIRC he mentioned that chat line(pop up window) has become his preferred line of communication when dealing with the public.

Congrats on the new sub…

I too popped onto the site as I was looking into possible units to replace my Carver sub with. I spoke with a knowledgeable source who suggested a XS15se in lieu of the VX15se I was initially there to get more detail on. Based on my media room size 2400 cu ft and the fact it is sealed with no opened walls (only a door), my new receiver (Denon AVR-X4000) and mains (Infinity Kappa 7 mk IIs) the sealed sub would be plenty and benefit greatly from the smallish-sealed room. I rarely listen at reference levels so that may have driven the suggestion as well.

Anyhow I was greatly impressed with the knowledge from the Chat person (can't recall the name).

Looking forward to picking my PSA sub, receivers (Denon AVR X-4000 and X3000) and my Panasonic projector (PTAE8000) up from the local Fedex store tonight!
