Default Active Crossover?! what?

I'm planning for a 4-way horn speaker. horn bassbin (midbass) + horn mid-range + horn tweeter and a supwoofer for lower frequencies. I'm going to use active Crossover but I have no idea what to use. sure drivers have different sensitivities and I'm gonna use L-pad to attuanate them to balance the sound.

I want your opinion about active XOvers. I'm pretty a newbie to this issue. thanks alot

Active speakers don't need and hence don't use L-pads.

rgds, sreten.

4way active speaker have 4 power amps, one fore each speaker
you control the level of each from the 4way crossover/preamp
most PA power amps are also built with level control at input

even your speakers are 4 way, it does not necassary mean active crossover has to be 4-way...it can be two way, split the signal for subwoofer and the rest, two amps per side required, and passive crossover for rest

or get a 3-way active crossover, you need three amps per side, and only have mid and tweeter passive crossover, (often just one cap)

if you decide 4-way active, maybe digital crossover is best option, than you (only) need four amps per side, no passive parts between amps and speakers

good luck!

lots of options...
