JBL L300

AFAIK, the 2231A was the professional equivalent to the 136A. Then the Alnico / cobalt crisis hit, and the magnets were converted (along with some magnetic gap geometry refinements) to the ceramic / ferrite magnets, leading to the 136H / 2231H versions. The 136A or H were the consumer versions used in the L300. The 2231H continued for a couple of years, then advanced to the 2235H with some minor changes to the coil / cone and possibly mass ring IIRC. The 2235H is the recommended recone and driver replacement per JBL. All 136 and 2231 recone kits were long ago exhausted and not renewed.
 
I see. I think I will try for a pair of 2235H, but if the others come along for the right price, o may jump on them. Thank you sir, you are always helpful.
 
What a great thread! L300's are my dream speaker for my living room but it will remain just a dream. Good on you for hanging in there on these.. Patience is a virtue!

Let me know if you need the 2235's, I've got plenty.

I would love a pair, thank you. I sent you a message, when you have time.

The lenses definitely take care of the beaming of the horns, the sweet spot is much wider now too.

Could anyone upload a few pictures of the original grills? Measurements would be great, but what I really am wondering about is the makeup of the framing, and the corners where they are attached. There are just not very many pictures of the back of the grills on the webs. Thank you.

Don't ever sell them, there really is no point...let me know if you need a hook up to make some grills...

If your offer still stands, I would like some pictures of how the grills are made, I don't have much to go on. Measurements would be great too, thanks.
 
@mech986 In post #103 of this thread, you mention that the original JBL configuration is reverse phase (positive to red pulls the woofer cone inward). Is this true for the 2235H as well?

Just preparing for when the woofers arrive. :)

IMHO you have there a pair of the finest loudspeakers from that era. They've certainly had a hard life. The woofers in them were made during the heyday of the car audio industry and the brand name "Rockwood" was an effort to establish brand recognition as being a hybrid of "Rock"ford Fosgate and Ken"wood." These products were sold at flea markets, bazaars, and liquidation events. Performance products they were not. Interestingly, Rockwood wasn't exclusive in this naming strategy - Alfine and Kenford were others.

What a buy. Once you've refurbished them you'll have a pair of speakers that are keepers for life.

This means the subwoofers are white van, right?
 
Thanks to mech986:

I m now the proud owner of a pair of 2235H.

:banana:

First listening impressions are: Wow!

Second: Imaging! Let me tell you about imaging. Vocals are rock solid, the only thing moving around is my arm hair. :) Things are being heard around here. :)

We are in the process of moving things around at our house, I will upload more pictures when I am moved into my new listening room.
 
Wow faber12! A two-year process and you finally got it all together. That's just awesome, congratulations :-)

I imagine from your comments that the wait was well worth it. Judging from your initial price of entry, along with the cost of the lenses and woofers, it seems like you've landed yourself a pair of fantastic speakers for not too much outlay. A great example of "bang for the buck" ;) That's one of the things I love about vintage audio, you can achieve really high quality sound without spending huge amounts of money!

I'm looking forward to hearing more about your listening impressions. Reading the thread makes me want to pull out my JBL L36s and get them refoamed. Nowhere near an L300 of course but you know..

DO IT Canuk!!!!!
 
As I said, I am in the process of rearranging our house. I used to have a 22 x 14 room upstairs that was rather hot in the summer and cold in the winter. We are going to use that room to make two bedrooms for the kids (with heating and AC taken care of). I will now have an 11 x 12 approximate room downstairs for listening. It will work out well, I am purging a lot of excess gear, and will be able to listen more often.

Unfortunately, for the next week or so, I can't listen to the L300s, as I have removed the woofers and lenses and repacked them until the L300s are carried down the stairs. :(

Such is life.

Worse things have happened.

We are going to be OK. :)

I am actually rather excited, as the new room will be very listening focused, instead of being my workshop as well. I will be using a room in the basement for gear storage and workshop.

I will upload pictures as soon as I have the new room set up properly, and you can all admire my lava lamp collection as well. :)

Yes, Valveglow, I will upload to your lava lamp thread, and I will also be prominately displaying a valve amp or two. :)

@canuckaudiog , get those JBLs repaired! :)

Also, when ready, I would love to entertain some local AKers for some DSOTM, or, if that is too stereotypical, whatever you want to hear. :)
