How much more bass from 2 JBL D123's?

[rudy sesztak]

I'm using 1 JBL D123 on a 3/4" open baffle board 24" high by 36" wide with a 077 tweeter 7 KC up. It sounds GREAT!! But the low end is weak.If I would put another D123 on the same board mounted next to the first one(horizontaly)How much would the low end improve? Would the OB airy, open sound suffer from the side by side usage of the D123"s? Thanks in advance for any advise from any of you. Most people on this forum aren"t in to Open Baffle sound, you should try it, the mid's ,low"s sound so open,airy and so CLEAR!!-RUDY

I don't think that you are going to get any useful bass from D123s on an open baffle. Even if you do improve the bass, you will be hurting the dispersion by putting two drivers side by side like that.
