Bought 2 pieces of this and drove together with Ken Kreisel Quattro Q125 systems.
However, left them back after a few weeks of use.
Fine construction quality with subtle design. The compactness makes it easy to install. Unfortunately growled both units. Not loud, but enough so annoying sometimes. Other subwoofers in the exact same plant has never behaved so. EQ I was not going to work as advertised. The question is if it ever did any good in my room. However, I note that this subwoofer goes deep and is quick off the mark. It can play very strong, especially one experiences it as if it has two. Can do wonders if you have the right kind of room and facility.
Got considerably better uniform deep bass with two Monitor Audio Apex AW-12 subwoofers instead I switched to. Suspect in my room makes front-firing subwoofers perform better. Although the AW-12 is technically easier and cheaper, the difference in perceived audio quality great. The room dictates the reslutatet over the subwoofer itself.
