But even without it the bass is powerful and musical. What makes this speaker special, aside from premium parts, is that its engineered by someone who really knows what he's doing. They do not have a bright, analytical sound like many audiophile-approved speakers. But I have heard detail with these that I ve not heard on very expensive stuff. Acoustic bass sounds better than on my Magnepans, which I d have thought impossible.
Voices sound very natural.
If you want accuracy and resolution without exaggerated sibilance or bright, aggressive treble, these are the ones. In other words you know what live music sounds like. The negatives, well they are black boxes with tweeters on top. Bass is good to somewhere in the lower 40s not 20s or 30s. But a 6.5 in woofer can only go so low and so loud.
