After running them for a few weeks, I have gotten to like them very much.

Even more so now that they're hooked up to my newly acquired ol' school Sima (SIM AUDIO) W-3050 amplifier.

At normal to moderately loud levels they can impersonate a larger pair of speakers, but there is so much you can accomplish with a 6.5 inch woofer.
They SB woofers start to sound funky, when asked to play low n loud and bottom out, not long after that.
Another thing i noticed was I prefer having the enclosures sealed, rather than ported. I lose a bit of low end, but not much....but above 90hz SQ is noticeably improved.

Ideally I will need to build or purchase an amplified sub to assist with low-end frequencies. (later this fall or winter)
This smells of processing and multiple amplification..mini dsp, to the rescue?
