Question 15" Or Larger 2 way coaxial drivers were there any 18" Coaxials made?

I an interested as well as my other loudspeaker projects for this year in building a large 2 way coaxial system.

Drivers that interest me as well as the Tannoy and in particular two models from Great Plains Audio their model 604-8H-III and the 604E series 2 look ideal.

The main problem is the cost of getting them over to the UK and future aftercare as I don't want to get involved in shipping to and from the UK if there is a problem

Hence my search for drivers available in the UK

Questions

Other than the Westrern Electric 4181a and the BTH K-10A 18" Coaxial Drivers, were there ever any other 18" Coaxial units made?

What UK available alternatives could I consider? I propose a system using around a 8-10 Cu Ft enclosure

Thanks

B&C makes great coaxials, and they are in Italy.
18" would have rather compromised midrange in my opinion.

This fits the bill the BTH K-10A 18" Coaxial Driver but far too much coin for me.

I wonder if there is a modern equivalent of them?

Yes, a search would help.

P.Audio used to make an 18" coax in their Blue Monster series. I've heard 2 pair, and worked with them some. Amazing driver, difficult crossover.

yeah ...... usual thing

Americans are fascinated with EU oldies , while EU boyz are fascinated with American oldies

so - Tanns are preputium priced in US , while Altec (and similar) are preputium priced in EU

just buy any 15" Tann ( patience and careful search on all add places) and enjoy

Altecs aren't better than Tann , and vice versa

Try to get some of the new Martin coaxials. They seem well designed.

One nice thing about the 18" coax is that the woofer cone is actually large enough to work as a decent horn/waveguide. 15" can be OK, but 18 is better.

That is along the lines of my thoughts
