As a result of your post I found some links to a DIY build for BMR philharmonic audio speaker including the kit and flat pack. The flat pack is the easiest construction I've ever seen. Maybe my next project.
Good deal on the find.
Care to post a link in case others are interested, too? [After I posted this response, I decided to do a bit of sleuthing and rediscovered Dennis Murphy's "MurphyBlaster Productions" website.] It's been a couple years since I last visited this site. http://murphyblaster.com/content.php?f=main.html
Any connection/direct experience with RAD or their products?
Some good parts shown, but much of the site is undeveloped and out of stock. Tough time for a start up. Note that it's a Canadian company. Pretty sketchy web site. I sent them a contact email. We'll see.
Good morning, JLM.
In the past several months, I've run across a couple reviews and a couple mentions of Rival drivers, but no personal experience. The mentions and reviews were positive. I don't recall where I read them....perhaps one place was on a FB Group(?). The prices for the two two-way kits w/front baffle included sure are enticing - $349, and $294!
