Hi there,

For the cost of dinner for two you can buy a Behringer 2310 XO. So much control for so few $, it's hard to beat. It's what I am doing for my 604-8H's

Thanks Guys for the advice so far.....

AB.... I'll attempt to PM Donald Patten

Ron.... I know splitting the "Simplified" crossover is quite "simple",he he, but I really want to split the stock dual attenuator Altec unit. I will build and use the woofer section of the "Simplified" if I must, but it would be a last resort.

Cal... I've owned and used a number of electronic crossovers, but always seem to go back to the passive ones. I'm not sure if they add or subtract something, but I always get the impression they change the sound, and not always for the better. Could be just me and my prejudices though. This is my home vinyl rig, and purity and simplicity seem to = more natural sound.

I'm including a pic of my shop rig in this post....Sorry to have to show it with it's JBL parts.I'll repent and try and be more Altec in the future! It is my experimenting setup....I built the 828 cabs with a lot of help from this board a few years ago, I don't think I ever posted a pic of it, so here it is.

828 cabs..... Dual layer 3/4" mdf inner walls, 2"x2" hard maple stringers, 3/4" oak ply outer wall, solid 3/4" white oak trim, solid horn flares.Weigh in at about 400 lbs a piece.Virtually no resonances, The detail from the 515B's is amazing..... The rest...

288B with 1005 Horns

JBL 2405 slots phase aligned on aluminum brackets above the horns

Jbl 2245H 18's... stereo sub cabs, Greg Timbers design.

At this particular moment, (and it changes almost daily)

845 triodes into Hiraga crossover for 288B-515B's

845's also power the slots through JBL 8000 khz crossover with L pad

Bryston 4B into Reckhorn crossovers for subs.

This is about the simplest electronics I use, and also sounds the best... I have quad amplified at times. A bugger to set.

Sorry for the mess, but its a working shop... I listen to this rig basically all day every day, needed something to compete with the db's from the power tools, and this setup wins every time!

Cheers.... Scott
