Genesis 300 transducers


I recently bought a pair of Genesis 300's. After setting them up in my room and making a bunch of measurements I noticed about a 10dB difference between the right and left speaker around 10kHz. At first I assumed that the tweeters had something funny going on, but after more study I noticed a difference in the planar transducer attachments.

One speaker has a red and black wire coming out of the transducer with two wire connectors connecting it to the wires coming off the cross over. The transducer also has a Bohlender and Graebner sticker on it.

On the other speaker (with lower output) there are no stickers and the wires coming off the transducer are gray and white. These wires are soldered to the wires coming off the crossover with heat shrink on them.

If there are any Genesis 300 owners, or 350's for that matter, out there. Could you tell me which is the original transducer? Also, does anyone have any suggestions on how to balance the sound of these two beasts without buying 2 new RD-48's from parts express?

It helped quite a bit. The imaging is much better. The only problems now are a bit of boom around 30 Hz and a slight lack of high frequency clarity. I think some room tweaks will improve these problems.
Svcan, I did find that the BG ribbons enhance the speaker's performance. Although most of the midrange attributes were very similar to the older ribbons, the dynamics and mid bass were improved considerably. For me, this was most notable on something like a firmly plucked bass string or a solo acoustic guitar.
Scvan, I would talk to Christos P. Skaloumbakas about the Genesis 300 speakers. He runs the Greek audiophile society in Greece. He's has the Genesis 300 speakers for like 15 years and knows everything about them. He's also had his Genesis 300 modified.
I would talk to him.
Here's his website where he talks about the Genesis 300.
His system is also on Youtube.
I put the links to both below

From what I gather, my Genesis 2's have the Carver ribbon on them. Anyone certain of this ? Also, does anyone have any information or copies of reviews, or manuals on the Genesis 2 system. Your help is appreciated.
