1. suppose a 10 in. LF driver and a 12 in. LF driver have the same rated FR.....

why does the 12 sound better ? is it because of the added mass/radiating area moving more air ?

2. Whats up with all these 6.5 in LFs now ? They produce lots of bass. What has changed , letting smaller LFs produce like the older / larger LFs ?

I have AR powered towers in my HT system and the pair of un powered 8's with powered 8's in the rears produce incredible bass .

So why are the smaller drivers producing what we used to expect from 8's or 10's ?

Most forum members don't apparently like the smaller drivers , judging by how many here have 15's and 18's .
