It's been an interesting day. Darrel (Ro-Blower on the Decware Forum) brought his new prototype open baffle speakers over today. These are a very retro looking speaker that is definately not your run of the mill speaker. They are actually quite cool looking. Here's some pics.

The bass goes somewhat deeper then my own EV open baffles (with my subs off). Theye are down about 4.5 dB at 50Hz. Bass was clean with a natural, uncolored sound, with that certain boxless quality that OB's do so well. The mids were a nice, not overly forward sound that one could listen to all day without listener fatique (we did listen for a good part of the day). The highs were clear and matched the rest of the sound nicely. They had the big soundstage that all OB's seem to have. These speakers are very efficient at about 100dB sensitivity. Drivers used are 15" Eminence Alpha and Pyle bullet tweeter.
For those interested, here's a thread on the Decware forum with more details.

All in all, I had a fun day listening to these.

Dave

Hi Dave,

Sounds interesting. Alpha 15's have real high Q, so I'll bet they sound good on those open baffles. I couldn't access the pictures from the link though, so I couldn't see 'em. Yahoo photos was asking me to sign in to view. Maybe you can set them to be public?

I think I should have signed out before copying the link.

If the link to the Mini Planers didn't work, try this.

That did it! Wow! Those are super cool looking! What tweeter is that? What crossover did you use?

Hey Wayne,
Thankyou so very much for the compliments!
The tweeter is made by Pyle pro ,
I used only the cap. that came with it as the cross from mid to high.
Also run an L-pad to help balance the 106 db sen. of the tweeter to the approx. 98 of the Eminence 15"er. Also doped and tweeked the 15 and foam /felt wrapped the rear of the tweeter. Sort of turned this coaxialy mounted tweeter assembly in a pseudo phase plug of sorts.Seems to do the job. This speaker has been designed to serve as an intro level audiophile speaker for budget conscious music lover.
I have gone over more construction detaild on th Decware forum.
Thanks again
Darrel

Wayne,

The tweeter is a Pyle pro bullet tweeter. The builder and designer of these nice OB's is Darrel Hawthorne, a regular over at the Decware Forum. Here's a thread that I started there.

Hi Darrel,

Sounds really neat! What size capacitor comes with the tweeter?

Hey Wayne.

Here is the spec. on that tweeter:
Partsexpress #272-115
pdbt28
correction* 104 db.sen
The assemble is all wrapped up (foam /felt)
but if memory serves me it came with 3.3uf cap.
I ran thru several tweeters and stoped with this one as it had the least compromises/ most potential in the price range I wanted .
Thanks again for the nice words Wayne
Darrel
