12" Utah Pandore Open Baffles

Another project finished this week is the Open Baffled 12" Utah Pandore speakers.

More bass than the 8" Realistic Americana Open Baffle speakers that I did 2 weeks ago, there is also a compression horn driver for the highs.

these speakers sound very natural and I do not miss the boxed bass that are part of every other speaker.

The results of this project came out much better than my expectations. I am pleased as punch with theses speakers and will most likely keep with the 12" open baffle designs. Although I still have a few 8" coaxial driver that will be featured soon.

And of course these are being driven by a SET tube amp.

Very impressed....

Realistic Americana Open Baffle Speakers

Another idea planted in the depths of November is to start making open baffle speakers using vintage Utah, Realistic, Electro Voice, Knight and Lafayette full range, co axial and tri axial speakers.

The first one I  built was with a full range 8 inch Realistic Americana. I used a nice 3/4 inch plywood with a light mahogany veneer. These are drivers from the late 1960's into the early 70's. Made by Utah and re branded as Realistic. The frequency range is 45-18000hz with pretty high sensitivity.

The legs are from a pair of children chairs that I found at a thrift store.

I got a chance to sit back and listen last night and I liked what I heard. I had to bump the bass and treble for my taste. I found that they worked best around 2 feet from the back wall. I have read that it is best to do an open baffle with full range speakers, simplicity is the key with no crossover phase shift, or in other words coherent.

More to come later on my sound impressions, so far I prefer it to boxed speakers.
