    I upgraded supercube 2000 with the 4000 a few weeks ago and I'm extremely happy with the upgrade. The supercube 4000 completely fills in the mid and low range even at half power. The sound is clean and natural. Having the remote is a nice option

    Best sub I’ve owned. Perfect in the 75 - 80hz range. Not using for home theatre so can’t comment on its capability there. Great for stereo speakers with good lower mid base. Using with bohlender graebener 520. Terrific deal at Best Buy too!

    I was so please with the Definitive Technology SuperCube 4000 subwoofer that I purchased two of them to add to my Hoe Theater System. Loved the wireless capability allowing me to move them around the room to the spot that sounds best.

    As advertised, the sound of every individual bass note in music playback is clearly delineated. In home theater use the LFE impact and depth is more than sufficient for small to medium size rooms.

    Legit subwoofer that's not overpowering to the theater. Can adjust the bass to your own preference. Def tech speakers are my favorite bc they are clear and immersive throughout my whole 2 story family room.

    You need two of the speakers depending on the size of your leaving Room. Small leaving room, one is ok, but a huge leaving room two is better.

    The SuperCube 4000 8" is one of the best subwoofer. Very low distortation and very high out put. It is very impressive and worth every dime.

    sounds great for its size. It does not fill my room with really deep bass like I wish it would. I have fairly tall ceilings and large open floor plan.

    Sounds great until it blows. Had this blow on me twice. Had it fixed once and returned it the 2nd time. Needs woofers that can handle the power this thing puts out.
