I've been building speakers of one kind or another for 30 years, mostly as a hobby, starting in high school. Professional design and installation for 3 years before going into a different business.
I've built direct radiator boxes, bandpass, ported, all of them. I did not like horns until I came across the BFM designs. Updated horns to take advantage of new driver technology is a vast improvement over the horns of yesteryear. Smaller, better, more efficient. Harder to build, worth the effort.
Been in business for myself for over 25 years. Customer satisfaction and prompt action are hallmarks of my businesses.
