Hi Fred,
How much eq you would need would just depend on your drivers. I needed some EQ on both midbass and midrange to get it to meet my crossover targets. Here's my JBL 2225 in its sealed enclosure along with my target and the eq needed.

Thanks John... I'm curious as to what Active XO/DSP software, and what amps for multi-amping, and source/s you use.
The convenience of changing XO settings on the fly to hear the differences is really nifty..
Regards...
Hi Fred,
It sounds weird, but I use an old Mark Levinson car amplifier I have that has an AD Sharc built in along with 16 channels of discrete amplifiers. I'm using Crown amps for the low frequency channels. I have a miniDSP setup that I eventually want to transition to that will let me use FIR filters in addition to parametric ones. Then I'll have to find some different HF amps to go with that. I do all my filter design and measurements with Matlab.
Hi John.. Thanks for the details, miniDSP seems like a good affordable kit for relative new comers to active-digital.. That's actually cool, ML car amps. If they're relatively old, I'm also a fan of Madrigal Audo Labs designs, even if I still havr a bias for glassware. I guess you have the Harman setup for the mids and up since HK owns both JBL and ML these days.. Nice, I've seen a few folks use new Crown amps for the LF and low mids.
Thanks again.
Regards....
