I recently purchased a pair of SDA-1Cs to upgrade my system (previously SDA-2Bs). I was expecting a minor difference, but the new speakers are superb.
That said, when playing back some reference tones through the speakers, they sound quite different. The Right speaker is noticeably "flat" (even with the test tone), with less bass. Testing with the SPL meter, it is coming out ~2dB less than the Left speaker.
I have tested with an alternate set of speakers to verify the problem is not with my amplifier, and I don't have an interconnect cable. (I intend to build one given some free time).
It's going to be a couple of weeks before I can break out my toolbox to open it up so I can examine the internals. So in the meantime, does anybody have any suggestions as to where the problem may be and where to focus my troubleshooting?
(Side note: DarqueKnight, if you happen to read this, how do I go about ordering a copy of the SDA Compendium if I can't PM or e-mail you?)
