I have assembled a small assortment of drivers, and I have my prototype imperial.  When I get some time, I will make some adaptors to mount a 12” driver over a 15” hole, and see how a 15” driver plays with a 12” driver in the imperial.

I am mainly curious if a 15” driver will bully a 12” driver due to the air interaction though the throat.

What I will be playing with:

Zenith 12” speaker
OEM 12” speaker http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=5802237164&rd=1&sspagename=ST...

Goldwood 1558
Profile J15

I am also curious what a mismatched pair of 12” speakers in an imperial will sound like.

School is getting stressful, so the experimenting will happen soon, it helps me relax.
