The front firing 12″ bass driver can pack some serious bass punch when demanded. Don’t underestimate its conservative 400W per channel because when demanded the Q401e can really rock. Rated to go down to 25Hz and work up till 125Hz, the Q401e with its wide array of controls can be paired seamlessly to any speakers you have. It was very easy to fine tune it to the point where the bass notes was just “coming through” the main stereo speakers it was paired with and not drawing attention to where it was placed. There was no “bloated” overlapping in the mid-bass area like some subs with lesser control features. We found the Q401e to be more “musical” than a similarly sized Velodyne or JL Audio sub. It may not have the hard “punch” as the other two brands but it delivered enough to get us nodding happily. It was its easy ability to blend naturally with different speakers we had it paired with that really impress us.
Cosmetically, the sub is in very nice shape. Minor scuff marks and here and there but nothing major. We do not have the original packaging but will securely pack it for safe shipping. Manual is available online.
