Hello World!
This is my first post here, been a member for a long time though.
First of all, I'm in Iceland so parts are scarce; gotta make things work! hehe
Ok, I'm gathering up some components and parts for a pair of two-way, 10" or 12" studio monitors.
I've been looking at opinions on the JBL 4410A and 4412A and have come to the conclusion that the 10" driver from them (127H-1) might be the business*.
*unless someone convinces me otherwise.
I've just bought a pair of vintage JBL 3110a Crossovers, albeit their x-over freq. is 800 Hz (I would've aimed at the upper 1.8 KHz, but then again I'm a novice!)
It was sort of an impulse buy; the HF output is "ideally" for a 16 ohm Compression Driver / Horn...
I'm interested in ribbon tweeters, but have learnt that they are limited to really high frequencies.
Except for the original Heil Air Motion Transformer; used in one two-way design from Heil?
Today I found a beat up pair of old SEAS 403 which have a reflex port and quite possibly the drivers from them are useable, who knows.
But I was mainly eye-balling the cabinets; they have nice dimensions, adequately deep in my opinion.
(I don't mind a plate over the HF hole; á-la 4331 😉
Thanks,
any ideas or pointers?
Sorry for the long write up!

Greets!
Why choose a driver that's so old even its OEM repair parts are long since discontinued, though hopefully these generic? replacements are good enough?
The retail/aftermarket folks tend to make ~replicas of popular designs, so a good one to research.
Regardless, probably best to (cross) post on the Lansing/Heritage Forum.

Hey GM, thanks a ton for the reply 🙂
I don't have this written/carved in stone hehe
Just trying to get some guidelines for this idea...
Theoretically, if one were to use a 10" driver with a 800 Hz crossover; what would be used for the higher frequencies? (in a two way system)

This might work above a 10 or 12": https://www.diyaudio.com/community/threads/acoustic-horn-design-the-easy-way-ath4.338806/ 🙂
(combined with a compression driver)

You're welcome!
Historically, a large horn 😉, one or two wide range tweeters or even a tweeter array or fast forward some decades to a (not so) short line array, though nowadays a true co-ax or tiny 'FR' driver are the 'hot ticket' for DIYers.
