I have a pair of acoustic research "active partner" speakers in need of a power adapter. Above the entrance of the plug in print it has DC 11.5 V. Need a compatible adapter.

DC 12v adapters are common and I think that would work. The similar "Powered Partner" speakers used a 14v DC adapter. Just check the size of the plug and the configuration (center pin is +). Radio Shack and other sellers have universal adapters.

Core in center of speaker is dented

It's just a dust cover. If it is not affecting the sound quality, just leave it alone. You may make it worse by trying to fix it.

JBL Subwoofer - Intermittent operation

Sometimes bad caps show a lifting or rounding of the top of the cap, sometimes this top will split from heat and pressure and sometimes it will not show any sign of damage but will be dry inside and its capacitance value will drop to a very low value. Replace the big power supply caps and test again. Get the same size, value and voltage rating. You can go higher on voltage rating and a bit on value. Getting a similar size or something that will fit in the same space is important also.

Jbl eon

the eon woofer is designed to fit the small frame of the inside cabinet. The EV woofers look too deep to fit but you can try. I do think that the built in amps were set to work with only the JBL woofers so there might be a signal problem using the built in amp. The eon face seems to have their own screws to hold the grill so if they aren't holding you can drop some cement to help hold the srews in place. The front does not allow removal of the woofer so it seems whatever you do should not effect anything.

Jbl distortion! frame warped?

Nope. WE have about 50 of these with no problems. Please describe the type of distortion that you have. It may be as simple as a bad transistor in the power amp.
