Help with JBL c60 Soveregin s8r speakers???

Hey Guys.

I recently came across the craigslist find of a lifetime a set of JBL c60's with the s8r driver package. I would love to talk with anyone that has experience with these. So far the sound is pretty good and i know it is to be some of the best. The giant 375 mid horns are ear piercing loud, i have played with the crossovers and tamed them a bit but still... I would like to ask about the best way to run these i read alot about tri amping and using a active crossover and cutting out the lx5 and n7000. My first try at listing was thru my pioneer sx-1050, with a moscode super it phono pre that did not go well at all. Now they are hooked up to a adcom gfa-555 sounds better but not great. A am starting to fear i cannot afford these speakers, meaning yes i have them, great, but now what.. The gear to run these guys well may be out of my reach. Again please let me know if ya know anything about these JBL's.. Thanks for your time
Zack

Hey thanks for the repley. I have read of others saying the same thing. I do not have the skills to custom build a set of crossovers. And your right i dont want to mess with the original crossover.. What i was thing of is getting an active crossover and bi anping.. Would i need one ss amp for the woofers an adcom gfa-555 that i have for now and and one tube amp for the tweeters and horns. Or do i need two tube amps one for tweeters and other for the mid horns. Someone i know has a mcintoch 240 he wants to let go of, do you think it can drive the 2 075's and the two 375's with just 40 watts per channel. I am new to tube amps and juct can not understand how a 40 watt tupe amp can compare to a 150 watt or so ss amp.

Thanks for your help.

Hey guys, thanks fo the great info.. They do sit on carpet, so that is a plus.. I do not have the jbl lens's on them. they were damaged. I just picked up a set on the bay. I think that will also help..

Yes i think the way to go is the bi-amping. I listen to mostly 70's and 80' rock and i like it loud.. All on vinyl.

I did get the Mcintosh gear, he told me to take it and play with it. It has been sitting in his attic boxed up for over 26 years. His stuff is from around 1968 it had some service info dated 1969. He has a mc 240 amp, a c 22 preamp, and a mr67 tunner, no wooden cases..

I made up a home made power supply from a box with a dimmer switch to a box with a receptacle to slowley bring the gear up to power. I took off all the covers and looked for anything that did not look right. Then powered it up ..

WOW what a difference the 240 made with the sound. The highs and mids are sweet. The bass is lacking when the volume is pushed, the reason to bi amp. But i can get a feal for what they have to offer, They are definitely NOT getting parted out..

I know the mc gear needs a full tune up by someone. I was thinking classic audio in NY i know nothing about them but have seen others talk about them. Do you guys have any sugestions. The amp worked great the pre amp powers up and all looks good but when i hook it to the amp i get a real lound hum no music. The amp sounded great with a low level adcom pre. Cant wait to hear it with a good pre. I have no clue what is wrong with the c22 pre. And the tunner powers up but has a cracked tube so i did not want to run it. All are a one owner set, and rate around high 7 to low 8 on a scale of 10 in looks. He wants $4,000.00 for all. I dont know with the c-22 not working right. Any thoughts??
