I have been pondering for a while on a new speaker project.
Having bashed the idea of a two way there are some benefits.
They can be quite sensitive and usable on a range of amps.
A two way is also not so demanding of less than perfect recordings and can be easier to listen to.
So my idea stems from looking at some of the JBL 2532-3 1.5 inch horns and using the 2435 be driver as the horn/driver.
For woofers I was looking at 15 inch cores reconed as 2234's or similar.
There are other variations using eighteensound horns and drivers and even a Le leach horn. Other woofers might include GPA 416 drivers.
This should provide some interesting discussion.
