need help picking a planar speaker

lochness · 28th May 2007, 08:11 PM

Well currently I plan on making some new two-way speakers for my stereo system. After listening to a friend system at school I decided to use planar-magnetic tweeters. Now I like my speakers to not only sound good but for the speaker drivers to match.
The specific tweeter I plan on using (though it isn't set in stone) is the Dayton PT2B-8 (it was the one that my friend uses so I know I like the way it sounds). Does anyone know of an affordable planar midrange/woofer that would work well with it?
I am willing to change the tweeter I am using so long as it is still low cost.

You might want to take a look at the Bohlender Graebener (aka BG Corp) transducers at Parts Express:

Some testing of the big RD-75:

You need a standard woofer (not a planar, aka ribon). What idea do you have in mind?

Zaph has published some very useful tests of planar and ribbon tweeters here: http://www.zaphaudio.com/nondomes/. Of the ones he tested he liked the Bohlender Graebener Neo3 PDR most. The rest of nondome tweeters had relatively high distortion at lower frequencies which would force you to use a higher crossover point. This in turn suggests a smaller woofer that has a relatvely high crossover point and careful crossover design. Zaph also documents this issue here: http://www.zaphaudio.com/Givler1.html

The Soundon audio maybe is a good choose for you.

Hi denbo123,
do you work there?
do you have a distributor (in small quantities) for the West?
do all the speakers have technical specifications, with them being tested in the factory?
Just asking.
