Ha! AT-1 not too sensitive @ 87.5 dB (accounting for 6 ohm instead of 8ohm if comparing to other 8 ohm speakers).

In general, for high sensitivity like over 93 dB you'll need to see larger drivers, larger box size, and less extension.
This is a medium size box, with extension that is pretty deep into subwoofer territory. Two 5.25" drivers is too little displacement for that kind of extension AND good sensitivity.

So, the latter suffers.

So...the use-case for these speakers are...2 channel (no sub)?
