So the real downside is by cutting our amp in half to power the highs and lows seperatly, we our putting a limit on what can come out at the lower frequencies......
(this is 2x true if we go 4ohms x 2 bridged to 4ohms x 4 biamped with a 4channel amp which some may be thinking of doing)
IMO it makes more sense to use say, 60watts for the lows and 40 for the highs... (or some varation like that)....
that said my aim might be to look for a pair of matching 60/40 4ch amps and bridge em down for a killer 2way biamped system...

Glad that we finally all agree
have a good weekend!

I would agree, active is a much better choice when you have the option (as I do in my personal car). Although the 3db gain is a little over stated in my opinion. Each passive crossover will be different. I've built some were I'm sure on the average you would gain much more then 3db and other where the gain would be at a minimum. The quality of the parts you use in a passive crossover will also help determin how much "power" your going to loose.
I've heard the Lynn product. I cant really say what the best is though, if you looking for a really nice affordable ($2500) and efficient monitor I would suggest listening to the MM DeCapo-i. Probably the best in the world for the price. The best speaker I've ever heared???????????????? Lots of nice stuff comes to mind, Meadowlark make some really nice products as do Avalon and Revel. There are just too many to name. I guess that's what nice about audio, there is something for everyone.
My stuff is good too. LOL.
