  3. SVS - PB-3000 Subwoofer - Black Ash - Front_Zoom

    Model: PB-3000- SUBWOOFER - BLACK ASH
    SKU: 6315938
    Top comment

    "But, no problem, because through the magic of Bluetooth and my cell phone using the SVS app there was no need to move the speaker to get to the controls. What I am not sure of is whether using two SVS 2000 or two SVS 1000 speakers would have given the same results. ...I also realized that if I move and am able to have my subs showing, the black ash would match my floor standing speakers better. So, to not spend much more money than the SB 16, I figured a pair of SB 3000s would be the ticket in black ash and would easily hide in wife's decor. "

  6. Bose - Sub1 Powered Bass Module - Black - Front_Zoom

    Model: 840918-1100
    SKU: 6448577
    Top comment

    "I purchased this sub 1 bass unit to compliment a pair of SPro Plus PA speakers. The speakers alone sound pretty loud, but once you add the sub1 you truly hear and feel the fullness of what this 3piece Bose system can do. ...This was a great addition to a pair of Bose S1 pro Bluetooth speakers. Really makes them shine when you use the S1 filter on the sub. "

    See all customer reviews

    Product Description

    A powered, portable bass module, the Sub1 subwoofer combines with virtually any portable PA and delivers low-end performance down to 40 Hz. Its unique 7” × 13” high-excursion RaceTrack driver allows for an ultra-slim enclosure, delivering performance that rivals a traditional 12” woofer without the cumbersome size, freeing up room in your vehicle and on the stage. Compared to the Sub2 subwoofer, Sub1 is the more compact subwoofer option for the Bose L1 Pro32 system, combining seamlessly via single-cable SubMatch connectivity. You can stack multiple Sub1 subwoofers for even more low end — or to unleash Cardioid Mode for directional bass. With a Sub1, you get a subwoofer that goes virtually anywhere and effortlessly fills out your sound.
