Nice, thank you! No complaints about the extension, only SPL capability.
With regards to overall SPL output (if you don't mind more totally sloppy informal measurements) in my 200sqft den, they were able to put out a comfortable 80-85dB average (according to my cheap-o $12 SPL meter) on actual music, with decent room left over for dynamic peaks.
The was with my Emotiva A-100 (50W into 8ohms, 80W into 4ohms) with the volume knob at around 75% IIRC.
I didn't try to push them too much further than that as I rarely listen that loud... that was more than loud enough for me already. I would guess they had a few more dB to give but probably not too much more.
It certainly smokes the Pioneer, though, and at a very good price.
In terms of bass, absolutely. The Pioneers are nice, especially crossed over to subs. And they can be crossed over at 60hz instead of 80hz in my experience, which is nice. But without subs, the Pioneer's bass output turns into a flabby fart machine at higher SPLs. All flabby midbass hump, no deep extension. Nice at lower SPL though.
