These are not ribbon transducers in the true sense of the word. They are planar transducers with a flat voice coil fixed to a substrate. A ribbon...

Hi Pos, Really glad to see the DCX2496 used - and able to be used in the position of a DSP Network for M2 Rebuilds, close or not.. I have read...

Received tuesday (12 days, nice) the LP Gear N75ED Type 2 stylus for the M75ED/R-1000 EDT cartridge. Trip was different and cheaper this time, USPS...

Are the resistors for higher Q ts ?

Thank you! According to the posted specs the LE111A has nearly 1.2 ohm higher DCR than the LE111H. The L110 has (with 033, LE5-10 and LE111A...

Hi Anti K, if talking about THD, 2nd harmonic of 10kHz is 20kHz, so I will not pay any attentions about that. Be aware that 1W would produce over...

Requested DCR specs for LE111A Min. 5.5 - Max. 6.5 Ohms, Aquaplas on the back of the cone

I agree but it looks odd. Where is the black wire connected?? Almost looks like a jumper has been cut out. What are the "green" things? Wonder what...

Other than Harmon Cardon actually being Harman Kardon, ;) looks like probably a simple low pass filter for the subs ... Can't hurt to keep the high...

Hm, I think if I could get the 12-18 year material, I'd start there and maybe try to measure my way to the right foam compression level. Long process...

Very interesting information, thanks for posting this.

One of the things that has always perplexed me about these foam plugs is that the idea is to control or reduce unwanted resonances. To that end JBL...

Not quite having stock 4333B's, I replaced the 2235H's with 2216Nd's. Crossovers were replaced with the Pass charge coupled units. I did not A/B...

Looking closer at foam specs, they have huge variance in "typical lifetime", from very short up to 18 years, as best I could find. ...

Hi Dazzlingmd, we at this time have 21 pcs in the registry, but none of them with fabrication data. yours seem to be some of the oldest with...

Glad to own a piece of the heritage. Cant wait to get it reconed and hear the alnico smooth sparkle.

I got a really nice deal on my 18ti's from a member here. Built just as well as full size JBL's and in VG condition... mostly bought for spare...

That SA is really well built . Didn't know I had one , still has price sticker from a thrift = $8.95 (probably got on a 50% day :) ) Have 2 or 3 of...

That's all I need to hear...

Thank you very much, you helped a lot. :) If you have a little time to take look at LE111A woofer specs and post it here.

Oh, thanks for the clarification grumpy. My Marantz pre has a 30hz filter option that I'm not using because the Ashly XR1000 claims to have a 20hz...

I added the comments on the list LE 261 (might be LE26-1? no LE 26 on the list), 3.4-4.3 ohm, Plastic Flange 116H 4.8-5.6 ohm 033 3.6-4.4...

Hi Gavin, First, welcome to the Lansing Heritage. You can't have it both ways, hi-fi sound with some drivers being pro, and as you say some...

nice job on the L7. The original base is atrocious, as it is on the L5, but the weight of the L7 makes it unmanageable.

Wondering about 2216Nd as a current/serviceable replacement, possibly an improvement... seems like someone may have tried this in an L300 (not far...
