L100

[Rusnzha]

I have a pair of L100s. They have the 123A-1 woofers. I also have a set of the 123A-3s. Is the porting the same or different for each of these. Would the -3s be properly tuned If I put them into this cabinet?

Well why not just try?? I would think you would be fine. Curious but do the -3 have a larger pot structure??

I did just stick them in there -- sounded good. I discovered somewhere on this site (I wish I could remember where) which boxes went with which version. The early L100 had one box. The -1 and the -3 woofers had the same box. My guess is that this means that the box I have is fine for either. Thanks -- Russ

You're not alone! Always try the Search function button - quite useful! , but the architecture of the Forum is everyday a bit more blurred amongst the parses that were envisioned...

I have a set of L-100 Century, the one with all three drivers in a straight line. The port on these is just a hole in the baffle with no port tube at all. On another set that I had a while back, there was an elbow shaped plastic tube in the port. The ones with the plastic tube had the 123A-3 woofers, and they did not say Century on the baffle.

Interesting! Mine came with the -1 woofer, have the elbow shaped port and have "century" on the crossover.
Rob -- The size of the pot (magnet structure) seems to be the same. The frame is more massive.-- Russ

That, is the first-iteration of the L100's. They later migrated away from the "linear array" configuration (if they only knew what we know now... ) and started the cluster approach, and added length to the duct.

I'm nearly positive a one "Giskard" here would be able to recount all that history, and how!

Here's that first L100 (third from Left) with the LE20 tweet. The lineage here is (L-to-R) the 4311, later iteration of the L100 (circa 1973), Original L100, and Don's Favorite - the oh-so-rare 4310....
