No Baffle over Open Baffle Full Rangers

[Poultrygeist]

No baffle four inch neodymium full range drivers over open baffle 17inch Sansui full range woofers. System is bi-amped with SET tube amp for upper frequencies and solid state for lower frequencies.

What's the advantage of no baffle instead of open baffle?

[Poultrygeist]

If you physically attach a speaker to a board there will be some resonance and coloration. The idea here is to minimize these for the main driver. I would also like to try magnet mounting the Alphas without a solid attachment to the lower baffle and an 8 inch wide bander in the "hanging by a thread configuration".

I've heard the "no baffle" speakers in the link below and they were outstanding. They were best enjoyed with eyes wide shut. :-)

These inexpensive 8 inch full rangers from Parts Express sound much better than the 4 inchers. Next I'll try a pair of 4.5 Fostex full rangers.

Would a Tripath chip amp adequately drive these? Redefining bang-for-the-buck.

The SET amp I use for the main driver makes all of 2.5 wpc. Full range high efficiency speakers love T-amps.

So how does the fostex sound in this configuration?

[Poultrygeist]

The Fostexs are better than the others, more detailed and the vibes from "Jazz at the Pawnshop" CD floated all over my garage this evening. I pulled them out of the Frugal Horns MkIII where they really work best and now they must go back.

Yes... Donate all your projects to me... :devil:

Ajani lives all the way in Jamaica...I'm in California so it only makes sense that they should go to me first :devil::thumbsup:

If you guys were motivated you could build better than my humble efforts. Being retired with a garage and a few tools helps.

I'm interested in combining art and audio. A flat open baffle speaker could make a nice canvas.
