Proac Response 4 Drivers

210.50.30.4

Posted by Terry Demol on September 17, 2001 at 15:33:18

Hi all,

I am auditioning a pair speakers cloned on
Proac R4. I would like to verify how close these are
to original Proacs.

Drivers used are:
Bass drivers - ATC SB75-234 (cant see SC or LC)
Mid drivers - ATC SM75-150 std (not special)
Tweeter is Scanspeak D2905/9000

Any one know what the original driver compliment was?

Anyone know Xover component values or brands of
caps. I have mapped the Xover circuit out.

The speakers sound reasonably good but a bit
bright in upper mids lower treble. Mid drivers
look like they need re-doping.

Thanks for any help, you can contact me
direct with any of this info.

Regards,

Terry Demol
