Hope I'm posting this in the right part of the forums - if not someone can yell at me, and I'm sure they will...
Does anyone know offhand what the L100 boxes are made from - is it chipboard with...

Often wondered about this one. Would it cause a huge problem if you used a pin to pierce the dustcap and then (again using a pin - with the end bent maybe) to pull/pop the dimple? Does the dustcap...

Who cares what's inside - just admire the woodwork... That really is a work of art, and yes I found a timber merchant (yep that's what they're called here) who has Bubinja and all kinds of other...

Yo!!! Now that's what I've been looking for - the diagrams even look like they are for the crossovers in your Project May postings... Sorry for the delay in responding - I've been away on a "somewhat...

Hi Viking
Attached as promised are two quick and dirty scans from the orignial JBL manual. I will submit the whole thing for upload in a week or so - don't have time just now, but maybe this will be...

Thanks Gordon. Certainly the only labelling I can see on Don C's posting (in the Project May thread #44) is as you say - L100. Can't even see the value of the caps, probably because it is tucked away...

Hi Viking
Sorry - I don't have either the boxes or the book in front of me right now, and I cannot find any illustration on E-Bay that is good enough for me to advise you - but I think mine have a...

Thanks for your help - I couldn't find that info anywhere, although rummaging around the i'net I did find a table that showed generic values. Is N311C JBL's disignation for the L100 crossover?...

I have a relatively early pair of L100a - and the "owner's manual" for same. The manual simply states that you should set the brilliance and presence controls to the "laboritory standard" (marked on...

On the same line - L25s sold to vendor on eBay last week 91.00 a pair - now he is selling them, or some very very similar at 89.95?? I really don't follow it, but maybe I'm just slow.:blink: But not...

Thank you for the comprehensive reply - and for sharing so many of your trade secrets! My L100's are in pretty good shape, but if, and when, I get around to rebuilding some that have been...

Oops - sorry Don, I should have checked to see who did the work on those crossovers. Humble apologies....:banghead:

Had a nasty noise from my old L100s last night - sounded like a capacitor dischaging...at least I hope that is what it was, otherwise it could be something expensive happening inside there or in my...

Does that mean - when "the studio monitor version was frequently mounted elevated and thus inverted" - that the technicians were yogaholics?

Just noticed something while browsing various bits on interesting information on the Lansing Heritage website... The L100 is shown in the original catalogue illustrations with the low-frequency...

Thanks Don - maybe I will do a Project May-style renovation on them. The cabinets themselves fine, but the foam grills were replaced with cloth by JBL in Australia years ago, and the agent is...

I have a pair of L100 in quite reasonable condition - purchased NEW in 1978, and just let do their thing ever since. However, now we are starting to play around with these things - I guess it is time...
