Get a carpet! I removed a rug from in front of my Hartsfields for cleaning and the sound quality declined. I'm listening to a pair of L-300s right now in a carpeted room and they sound perfect.

This week I find a moment to open my L300s and what a bad surprise to find a boomer JBL n°2135 (8ohm)!!! ,no 2231A or Le15, for mid 2420 (16ohm), for high 077 (8ohm). I think that I've found this big problem but now I have another one : Wich bass speaker must I buy , 2231A or LE15 ? and are the other speakers the good one ?
Waiting yours answers

The fact that you have a 2420 in there along with that woofer puts the entire system in the suspect category. You obviously are way beyond the niceties of sequential serial numbers... you have a pair of L-300s that have been resurrected from the dead using the Frankenstein method.
The 077 is correct. A 16 ohm 2420 is perfectly fine too, electrically and acoustically equivalent to the 8 ohm LE85 that should be there. (There are many threads explaining this elsewhere on this forum.)
The proper woofer is the 136A. An equivalent woofer is the 2231A, if you can't find either of these, a 2235H will also work well.
Due to the other changes, you should look at the crossover to make sure it is correct, and I would want to make sure the diaphragms in both the 2420 and 077 are correct.
I like your explanation , tomorrow I will call Frankenstein. I will buy new woofer but I'm not able to test the others speakers and I don't know how verify the network ?

The 2135 (D130) should be able to take a C8R2235 kit.
Is there a number written in chalk on the back of the 2135 cone?
Are both low frequency transducers 2135's?

I forgot about the 2135:o You might have something there, Giskard. I bet they did recone them. Still a Frankenstein though.Originally posted by Giskard

Hopefully a well done Frankenstein, however it is only a success if the end user likes them.
Who knows what kit though. It could be a real hack job. What does the dust cap look like? What does the surround and cone look like? Obviously something is quite wrong if he doesn't like the sound. A 2235H sounds great in an L300 or 4333. In any case, he has two decent cores if the mags are still strong.Originally posted by Mr. Widget

"Obviously something is quite wrong if he doesn't like the sound."
Well, sorta... not everyone likes the L-300. There are those that prefer, say a Klipschorn, or a whack on the head
Finnaly, I sell them yesterday. Now I will buy maybe a beautiful pair of 4350 A in mint condition. I post a new thread about this subject.
