Hi Guys,

Me and my father have been getting his original S8R system up and running again. His LE15A's needed both foaming and reconing, as one of the voice coils were toast.

We are still getting the rest of the system back in order. We used to have an SA600 integrated amp driving the system. It seemed to match the system very well. Now we have a Marantz 7T and 15. I have fond memories of the SA600 driving the speakers, and the 7T / 15 sound well, but the low frequency stuff seems too prominent, especially in a certain area 20 - 25 feet away from the speakers...like it hits a resonance or something. If I place the 50 hz filter on the 7T in line, it doesn't help much, but if I place the 100Hz in line, it does get better.

Just wondering if by having to recone LE15. is the PR15 now out of tune with the cabinet? How about the crossovers? Or, do you think the 7T/15 has flatter response further down low when compared to the old SA600. Wish I could just try the SA600 to compare, but it's caps are all dried out.

7T and 15 were just gone thru and returned to OEM spec by a Marantz expert, so they are up to date.

Regards,
Rich

Can't help about the electronics, but I would get both of your LE15As reconed and then your speakers should be good to go. The PR15s are tuned to that cabinet. Their tuning should not be changed.

Looking forward to you telling us how great they sound!

Thanks Widget. Sorry if I wasn't clear... they are already reconed and refoamed. I'm wondering if the recone is somehow causing the extra boom down low. I remember these from my childhood being fantastic.

Hi, Rich,

Sounds like you and your Dad have a fine project in the works. Where, may I ask, did you get your woofers reconed? If you didn't use an authorized JBL Service Center, and the wrong parts were used, that would very probably change the TS parameters of the woofers, and then the entire tuning would be off, hence a possible source of your booming bottom end. Since you are in Southern Cal., I hope you used our own Edgewound, who is an authorized JBL Service Center, or maybe Orange County Sound. Good luck with your system, and have fun. Take care, and God Bless!

Every Good Wish,
Doc

Hi Doc,

I in fact used a local JBL Authorized... OC Speaker. I wasn't aware of Edgewound. We were very concerned about who did the work. Dad has been stressing over getting it done for years (not playing it either) - I finally took them out and had it done. I hope it works out OK.

I think I should assume OC speaker did their job, right? We used the JBL factory parts, or so I paid for.
