XS30 Powered Subwoofer
  • The Power X line wouldn't be complete without a dual driver, sealed subwoofer. At 111lbs, the XS30 is moderately sized with a midbass "slam" factor that will leave you gasping for breath. In all but very large rooms, the XS30 will extend into single digits, creating a realistic sound field from almost any source material. The 725W DSP amplifier is specifically programmed to produce an unsurpassed transient response to minimize ringing and one note bass. The combination of a rigid MDF enclosure and a carefully engineered brace, the XS30 remains acoustically inert even while producing bass levels that will leave your home shuddering. The XS30 strikes the perfect engineering balance between remarkable performance and contemporary styling.

    * 2 meter ground plane (1/6 Octave smoothing)



    * The two curves in the graph depict the difference between a simulated in-room response and the measured ground plane response. The XS30 experiences a shallow 10dB/octave roll-off starting at 30Hz when measured in a ground plane (quasi-anechoic) environment. Once the XS30 is placed in a medium to large sized room, true extension to 9Hz-14Hz is typical. This boost in low end output is due to the phenomenon known as "room gain".
  • Todd Anderson gives his first impressions along with a detailed review of his dual XS30 setup. Please click the Home Theater Shack logo to read the entire review.
    "HOW DO THEY SOUND," you ask? Let's just say this: Incredible."
    "What I’ve found through my hours of movie watching is an extremely even, tight, and smooth bass. It’s not localized or one sided in it’s presentation - not in the slightest bit."

    Dave Upton, in his recent review of the XS30, has claimed it as "one of the finest values available in home theater today." Please click on the Home Theater Forum logo to read the review.
    "I listened to these albums for close to two hours and was thoroughly impressed by the articulation and natural sound of the XS30."
    "Overall, the XS30 delivered usable response down to the mid teens with clear, powerful and heavily visceral bass reproduction. Once I had it dialed in, the results were astounding."

    Thank you for the incredible subwoofer!

    I had no idea a sub could sound this good.

    My wife "approved" the purchase within 15 minutes of the first movie. She typically doesn't prefer the 5.1 audio "extra sound" while watching TV. Well, the audio has been used a lot more since adding the XS30. She explained the sound as much more natural. Your product description is so true "realistic sound field".

    FINALLY got my XS30 hooked up & calibrated! Rest of system is: PSB Synchrony Ones, PSB Synchrony One Center, PSB Synchrony two's for surrounds. My previous sub for last 8 years was another creation of yours, an SVS 20-39 PC+. Marantz AV8801 pre/pro - (also new!), B&K Ref. 200.7 amp. Room approx. 3000 CF. I calibrated with XT32, had all "the usual suspects" bass demo blu-rays lined up ready to go.....One problem: I said to myself "I'll just check it out with some music for a few minutes to make sure everything is working" I sat there for 4 hours, amazed at how clean & tight the XS30 was! I dug out DVD-A's & SACD's, and it was better than hearing them for the first time.

    When I finally got around to the blu-rays, it was more of the same. The way the XS30 just underpinned everything was astonishing. I'm 54 years old & have been interested in audio & video since I was 12. I have had a few components come through my hands that haven't been worth the money; many more that I thought were a good value for the money spent - and a precious few that returned much more enjoyment than the purchase price I had paid - with the XS30 topping this last category.

    Be well, and please continue to amaze us!!!!
