Gentlemen, I picked up a pair of these speakers, 10 inch woofer and dome mid and dome tweeter.
Real heavy and good looking but bad surrounds on the woofers.
I`m really wanting to replace the surrounds and keep them if they sound good. trouble is i wont know till i replace them.
Anyone have or have used them?
Thanks.

The 91 used the descendent of the AR1/AR3/3a woofer. The AR92 used the 10" that descends from the AR-2/2ax/5.Think of those as an AR3a in a tower cabinet with improved drivers and the felt "acoustic blanket around the mid and tweeter.
The AR91 woofer is really more like an 11", based on cone diameter, so it needs a rather special surround. I'm pretty sure the AR91 woofer frame is the same casting as the AR1 with two flatted sides on the rim.
A very nice speaker.
the 92 is the closer to the AR-5, the 91 to the AR 3a

Very good speakers! They use the same upper range drivers as the fantastic AR-9s. They don't have the bass of the AR-9 or 90, but they are quite good. You'll be very happy that you repaired them.The crossover caps need replacement for sure, but the coils are air core so leave them alone.
Do NOT add any more stuffing to the box. The amount of stuffing was very precisely calculated and controlled by AR, too much stuffing is not good.
Get the woofers refoamed and checked. Millersound (Bill Miller -- 215-412-7700) is a real good place to check with on the driver repairs.

Get 'em fixed up, and enjoy them!!
the direct successor in that genetic line. The AR-5's were perhaps the best of the entire single digit AR line, despite the fame of the 3 and 3a.
Attention to the xover components and layout can't hurt. Even taking it out completely into a plastic or wooden box, and even then try dry sand. IIRC a number of folks considered the 91's to be a slightly more lightfooted spkr, with deep bass, and more suitable to smaller rooms than the 9's / 90's.They can do layering in depth, but just not much.
If there are any ferrite core chokes on the mid and treble, and you can match them for ESR with air coil chokes do it, also replacethe caps with goodish metallised film caps, solens for the mid and bass and better than that in the treble.
If you wanted to biwire, do it between the bass and mids!
IF - when you are inside - the stuffing does NOT fill the box, think about going to a good bit more down near the bass driver. Add some cross braces, down there at least, and some bitumen pads on the walls near it, too.
Cones - or spikes - that bolt-through from the inside of the box, with a 'stiffening exterior bottom-plate' can't hurt either. Use ply for the plate! and put some nice chamfered timber edges on it so it becomes a plinth.

Don't jump to conclusions Tim. The AR verticals have excellent imaging capability - especially with better xover caps.
lose the ability.Every Allison tower or AR9x series I've heard still revealed the layering back of orchestra sections.
The little Allison cubes were VERY good at this, if you were in the near field. I sold a lot of them with NAD 7020 rcvrs plus A's eq box. SAF!!!!!!!
I just found the 3d-ness a little shortened is all.
I knew that better xover bits ought to really help though, as does removing them from the box.
