TL using a B200, Phillips dome and T27

[jbelvede]

About 40 years ago I built a transmission line speaker using the b200, a Philips dome for a midrange and a t27 tweeter. The design was a kit from a place called Gladstone Electronics, in Toronto, Canada. I loved them. The speakers and the information are long gone. I have been scanning the internet to try and find out about the kit. I am considering trying to make them again. The system was based on a UK magazine that had the diy instructions . Any help appreciated!

There was a similar project called the V3 by David Lyth. However, it seems to be bass reflex. On pg 81 here:

Thank you! That is not it but is good info . The midrange dome is the same.

I remember Gladstone, haven’t seen that line. That surprises me.

The article is a relex with a Volt woofer.

They were alright. I built two other systems for my cousin back then. One a T line and the other a reflex and both used the b139.

I skimmed the article and completely missed the Volt driver! It did mention a B220, though that is still not a B200.

I remembered that project because it mentioned Yamaha NS-1000 as a point of reference. At this time I had only read of the Yamaha, and it was many years later that I first heard it.

Shaun, I wanted thank you again for the link as well. I did some more digging and there is a huge amount of information. It brings back many good memories. I had never seen that website. Many thanks again.
