SRS with Dayton drivers

Any thoughts on this? Seller says he bought the speakers new and replaced to original drivers with the Dayton 4 ohms and that they sound good.

What do you guys think?e1hr5io6ntjo.png

    They are 1.2 TL's because they have SL 3000 tweeters and a couple of RD0 198's. Criminal what they did to them.

    I'm betting he's not the original owner. Hoping he's not anyway. If he bought these NEW, he probably paid close to $3,000.00 for them. These were an audiophile purchase. If so, being an audiophile, he should have enough sense to know what he had and not to $%^& 'em up. I agree with Nightfall wait for another pair.

    They probably don't sound very good that's why he is selling them.

    I think the seller is lying through his teeth. Unless he is letting them go for a hundred or two, run away, fast!

    Just going to throw this out.

    IF they're truly 1.2tl then they used 4 each of mw6503 and mw6511. Now those drivers had different parameters so if they are all the same 4ohm drivers with the same parameters then right off they're wrong.

    MW 6503 1.82 5.24 N 3.55 E - 3N/M 6.54 Ohms 29 Hertz

    MW 6511 1.405 4.34 N 3.496 E - 3N/M 3.13 Ohms 29 Hertz

    Run away do not look back.

    I mainly found these looking for an Adcom GFA-555. Hes selling the speakers together with amp and tuner (both adcom 555) for $1500.

    Without the interconnect?
    Those would make a great PA system.

    And because he didn't use an AI-1 transformer, he ruined the Adcom's! Wow, unbelievable.

    You cannot use mono blocks, dual mono or non-common ground amplifiers with SDA speakers without using an isolation transformer on the SDA cable. Damage to the speakers or amp(s) or both will occur otherwise.

    You might be able to strap the negative binding posts together with those amps, but looking at what he's done to them I think not.

    Some Adcom amps had a bad problem with caps leaking and ruining the boards. If that happened it may never of been a speaker problem.
    If he ran them with no cable there should never have been a problem. Only when the standard cable is used is when problems arise.

    I believe it may of been early gfa 565 monos that were problematic.

    My guess is that relay-less Adcom sent dc to the original drivers and that's why the junk replacements. Burnt voice coils on the originals, possible crossover issues now and a fire hazard Adcom amp. I see a pile of parts for way too much money.
