Super smooth sound on those!

Robert brought an Usher 2-way designed by Dennis Murphy. Sad we can’t buy those drivers anymore.

Ron brought an active 2-way using a PE 4 ch amp module.

JR shows why he is the king of getting the most out of budget drivers. These were stunning!

By far the most colorful speakers in the room! Ani’s girls did the custom artwork on his all active design.

—————

Nick’s sub/sat speakers are typical Nick - amazing sound & visual quality.

Bill did an amazing job on these. Just great top to bottom!

Kyle brought a pair of 1987 Speakerlab kits that he restored.

Kelly brought a Neil Blanchard transmission line design that uses SB drivers.

Dr. Scott recycled some abused little floorstanders and made a speaker most of us would have loved to have during our college days.

Craig brought his latest creations Rival woofers in the lowers and buyout SB mids and HiVi planers up top.

Here come the monsters! Glad these guys have strong backs!

Those 4 anarchy 7’s and seas ceramic coax? Curious being a seas fan boy.

Saw that too, and that is what it looks like to me.

You are correct, sir! These were very well received. A few of the group were still listening to them when I called it a night at 11:00.

Is there another set of passives on the other side?

Yes - I think he said they were the Dayton RS passives. More than enough bass for that room!

Each side: 1x Seas King Coax, 4x Anarchy, 4x 10” Dayton PRs and a massively complex XO. A lot of late night fund blasting at 100% all sorts of crazy bass tracks, trying to break either the amp or speakers. At end we gave up!

Disclaimer: no drivers or electronics were harmed in the process, not due to lack of trying.
