Default FS or Trade Beyma 8BX new 8" coax driver pair

Hello

Up for sale or trade a pair new (never mounted or used just tested if they work right) Beyma 8BX Coax drivers
Beyma 8 BX/N
These are high quality great sounding drivers!
With one driver you can get from 25Hz to 20KHz.

-This loudspeaker is a single unit, two-way system, comprising of an 8” bass driver and a concentrically mounted tweeter. This provides a single point source and reduces phasing problems in the crossover region. The bass unit features a 1”3/4 (40 mm.) voice coil attached to a polypropylene cone and copper ring on the pole piece. This provides a smoothly extended frequency response up to 7 kHz, with reduced harmonic distortion. The compression tweeter shows excellent efficiency and fast response to transient attacks.

Now I have to tel you when I received the drivers for some reason one tweeter sounded a bit louder.
For that reason the tweeters diaphragm was replaced (both driver) and I have a extra pair (new sealed in box, comes as a matched pair) tweeters diaphragm .
To access the tweeters diaphragm needed to cut a hole on the Beyma sticker.
Since I didn't planed to sell I didn't ordered new stickers.
You can see the price, these was ordered from Europe.
I ask $250US or
Trade $300 value Turntable Tonearm or a pair Tang Band W4-1337SD 4" Titanium Drivers and $100 cash.These drivers must be great condition! Also interested on a pair 7" Scan speak 18W/4531G00/ 4 Ohm or similar 8 Ohm drivers 18S/8531G00 / 18W/8531G00
Drivers must be good condition, not abused etc.
I have the original Beyma box to.
I think the asked price is fair, you will get the extra set diaphragm to.
Do not forget the inside tweeter diaphragms are NEW(was replaced and now sound both the same)!
In case I do not get offer I'll keep the drivers (really great drivers) The reason want to sell them I did started to many project I have no time for it also need some found to finish some of those I started already.
From 65-70L BR you can get 30Hz to 20KHz.
Buyer pay for the shipping or pick up.
For trade pick up would be the best. Pay pal OK but please ad 3% for pay pal fee.
Thanks for the interest

Greetings Gabor
