"Today was the very last time "I'll lift anything heavy, Doc, I swear!"
Having them on wheels makes it easier to finagle wiring, clean, etc in that busy part of the room.
The lifting was to replace metal studs with casters (the grills are getting Neodymiumed, also) as I my back really is shot. Legs have a bad case of the 'slows', too.
Golden Years, my ass!
Oh, you noticed the 4Pis are still on bricks? Those aren't bricks, they're the keystones for my Mausoleum. Thay stay.
While I was at it, I swapped the .625 light gauge coil for a 15 gauge Jantzen, 0.55mH. Steel core for air core. Most of the boominess I had is gone. The remainder is room-related.
For a treat, I'm playing the 2Pi Towers as mains. So far, they've done Tchaikowsky, Bonnie Raitt and Count Basie. It's a Buffet!
You know, it's not just about Eminence not being in the same conference as JBL; as good as the SB-29 Tweeter is, it can't keep up with the 4Pis horn. Before the H290C, I will now reveal, that wasn't true. The SB-29 is still very good, but it's not a horn.
Wayne, you really should buy a room at RMAF just to piss in the industries cornflakes. Maybe a Kickstarter?

Cmon Bill!
You big spkrs are like my little spkrs!
I can't wait to get cabs built for my 1501Fe's. Approx 4.2 cu ft tuned to 32Hz per JBL (4365 system).
They are like 2226's but with lower bass response and just slightly less spetacular midbass/midrange response. And 4 db less efficient.
Right now they are in 3 cu ft tuned to 36 hz.
You will have a reason to come to Ohio and listen to them.
Sorry for hijacking your thread!

Bill,
Yeah, I love the round wooden tractix Edgarhorns.
I have tried Yuichi horns and other non-round horns and just can't give up the 3-D holographic imaging!
These are the 350Hz and x-over will be approx 700hz to 1200hz to be determined as I go. I'm using a dbx driverack Pa + and 300B SET on the horns(2445/Be).
SS Mosfet amps Adcom 555 II or Soundcraftsman "shoebox" PM-860. Both amps are 200 wpc for the 1501Fe's.
My cab builder is one who likes to remain anomymous. I have several cabinets that he built and they are solid and dense with no box sound!
Regards, Ron
