Planars?

[flecom]

I was looking at building a pair of speakers and was thinking about doing something a bit wacky... has anyone heard the planars they sell on parts express? those Bohlender Graebener ones... either the smaller ones or the insanely large ones?

ex. Parts-Express.com - Search Results

i found a few projects online using the smaller Neo-8 in both single and line-array configurations... and then all sorts of insane projects using the RD75 75" planar driver with line arrays of larger drivers next to them etc...

anyone ever actually listen to any of these things? lol

thanks

Well you just got me interested in building speakers. Damn you.

hehe... it seems like a really good deal considering how expensive the speakers these drivers are found in...

i just wish i could listen to them before i consider buying some of the larger more expensive drivers

My current speakers use the Neo3, sound fantastic... got them for a steal too. Talked to the designer and apparently a new model is coming out soon.

Too bad I can't take these beauties to school with me. If I can come up with something cheaper than the Monsoon speakers I might be looking at a build (have a t amp coming anyway). The floor space of the Monsoons are pretty fantastic though.

Have never heard these drivers, but there's something about planars in general (my old Apogees, for instance) that I just can't get away from.

well i picked up a pair of the Bohlender Graebener Neo8-PDR Planar Transducers to play with... figure worse case scenario im out $125

700hz-20khz is pretty impressive... lets see if it sounds as impressive as the reviews make them out to be

Sweet.

Yes, do please report back, impressions, etc.

Someone went ahead and done dewed it.

[flecom]

uh huh... i dewed it

well i couldent bring myself to buy a pair of rd-75's (only $750/ea! ) so i figured this would be a good way to get my feet wet

[malldian]

Links to some of the projects you found?

For a while I thought of building this kit for it's ease of build, good price for value relationship but as with most diyers, I am looking for something better. Perhaps a small bookshelf that uses the B&G Neo8 or RT2C.

from what i have read online most people either run them naked - in a dipole configuration... or in a small cabinet (the datasheet measurements were made with a 6x6xlength of the driver enclosure)

there are a few projects online that use the giant RD75 drivers along with some larger drivers in a line-array configuration next to the planar driver... like this parts express project...

http://www.parts-express.com/projectshowcase/indexn.cfm?project=Colossi

there are some designs (including commercial ones) that use the RD8's in a line array configuration... im going to see what they sound like coupled with my existing speakers...

if they sound good im thinking coupling it with an 8 or 10" (non subwoofer) driver in a sealed enclosure with this planar mounted above it, either in its own enclosure or naked in a diplole configuration as some have suggested online also... but im wondering about strange reflections and interactions doing that...

if i do end up doing that 2-way config im going to use my macintosh 2105 to run the woofers, and my macintosh 2505 to drive the planars... should be pretty sweet
