Tannoy Brute Force OB ….. now Absolute WAF Tannoy OB

If you search in my previous posts , you’ll find enough details about this OB ;

Now just few general things – drivers used are Tannoy K3808 and Beyma SM115/N

Xover , still temporary (bean-counter’s drawer parts) , basically original Tannoy Pepperpot xover style with few changes and heavy iron choke for Beyma bass helper .

Baffle – multilayer of whatever I had , frame of square iron tubes , grills made of ply and anti-mosquito metal net/grid/whatever , fixed to spks through small Neo magnets.

I didn’t bought these ….. I had enough dead/bad HDDs , so just took Neos out and cut them in pieces with end- cutting nippers.

Sound …… not on par with my ref. RAC LC1B but certainly good enough for Audiophool Retirement (when one is becoming Musicaphile instead).

Still to do – final iteration of xover …… but I’m not in a hurry ……
