I won't argue about if the speakers will sound noticeably different after some use or not. But if you really want to exercise them in I would consider using Pink Noise instead of music. This way you hit the entire spectrum evenly and continuously.

I have TAD 4002 drivers on all my 402s (4 of them). You still need plenty of EQ for those CD horn/driver combos. When I was using passive networks I used an Ashly 31 band analog EQ on the tape monitor loop of my preamp. That was a very satisfying solution and was able to successfully flatten the response. I eventually did introduce a digital crossover but that is another subject. If you are using 402 horns you need EQ...........or some other horns.

Crown Drivecore XLS line up. Perfect for your application.

You could have purchased it all and sold the amp. Missed opportunity.

I bet the schematic is somewhere here on this forum. I got one from an old forum member "Father Bill", who used to build them. I eventually sold it. It is like 3 resistors, a pot, a terminal strip, and a couple of RCA jacks in a small enclosure. He charged me $20 I believe.

I use QSC PLX2 amps on bass cabinets and subs. but I was not satisfied with them on the top end in active systems nor for use with passive networks due to the top end. They are just not as resolving as better amps. I have a Crown XLS 2002 that easily bests the QSC amps for every application I have tried it on. It is a class D with plenty of power. You could get away with one of those on the mains and probably be happy. Decent amount of detail.

My cornwalls have very prominent bass. So something may not be right with your setup or room. it may also be that nothing at all is wrong and your other speakers just had more bass.

Are you able to take any frequency response measurements? You would be able to spot the issue pretty quickly that way.

I agree. There's a guy looking for an NBS for like a year now. That could be gone later today.

I wanna see a sasquatch.

Yes, Pfohl's many times. I really liked the original Hurricanes with Mark Bosch (guitar), Arthur Nielson (guitar), Renny Xosa (bass) Dan Hickey (Drums), Duane Evans (keys), and Linda Miller (vocals). This was a damn serious rock band. Later, he got a less serious group together...........a bunch he could control easier. The group above were seasoned professionals that wanted to be paid like professionals. I was at Longbranch Park and Weedsport Speedway where it all started, then Landmark Theater, and everywhere else he went. Pfohl's was the start of every summer. Then there were the Christmas shows.

A Syracuse staple. Saw this guy and his "hurricanes" many many times over the years. Great live performer.

Interesting. I have never seen a 402 clone. Will you tell us about them?

Really nice!!
