I have personal experience with a one-off crossover rebuild that Danny
performed last summer on my circa 1988 Tannoy FSM speakers.
The speakers sounded pretty good before I brought them to him.
He measured the existing frequency responses, cabinet resonances and crossover components. They performed poorly on the tests. He started over from scratch.
Once the new parts burned in -400 hours- the sound was much better. He also
sold me some no-rez for the insides and suggested adding bracing inside
in a couple spots.
Was this worth the $200 he charged? Heck yes.
I also had the opportunity to hear his open baffle system
with his amazing Dodd gear. The $4k his smaller Open baffle kit sells
is a steal. I don't think there is an $8k speaker that comes close.
Let's hope he is in business to make money otherwise
his doors would close. I bought one of his power cables
just to support his business. For the $300 I spent I have
no complaints.
He is one of the more Legit people in the industry.
I love his exposees on brands people think are "High Quality".
He shows the crap they use inside. Other Reviewers need to
learn some of his skills.
He is the Real Deal.
