I have collected for about 32 years while I listened to my LE15a 375/2395 setup with 2441 diaphragms. I cant remember how many tweeter ideas never worked out. JVC Zero 3 ribbons, BG ribbons, 2405 etc

7 years ago I added a pair of 2245 subs so concert DVDs play like real. Always used electronic xover RANE AC2/3 and bi/tri amped.

Finally two years ago I replaced the 375 with the 476Be.



Now I have been playing the Harman video game, http://harmanhowtolisten.blogspot.com/ It has made me think about the bottom end.

It sounds great but is there anything more I can do? I have woofer choices. Keep the LE15a or use a pair of these.... ?
2235 1500AL 1501AL

then the subwoofer choice...
Keep the pair of 2245 ported 8 cu ft or use 4 smaller subs? I have 8 of the REVEL 15" woofer from the sub30 (?) and the PR15 passive radiators

I am leaning towards the smaller subs because the 2245 cabs are so large I had to pair them together straight in front of me. Then cross over at 70 Hz to keep from noticing where they are. There are deep nulls. How is this avoided in a normal room except with multiple subs

I intend to keep the three way configuration, any opinions? Seal the 15 box so the "unused port" does not interact with the subs?
It playes plenty loud, I am more concerned with improving LF imaging.
