Yea, in terms of electronic music bass is of highest importance. Some initially "warm" music styles, like jazz/blues will benefit from it.
The way rock/metal is played , on bassy system sometimes seems too bulky and muddy for me. Like it is just long "booooom", through which no rhythm guitar can be heard, as well as solos sound like the are distant.
It is possible. So out of specs it seems I'll get 6.5" woofers instead of 5.25". Does it tend to improve mids (that's where all guitars are) and not drown them in excessive bass?
If budget is stretched to 6000F's, then they fall in the same price category as RP-280F's, so here comes the new challenger.
