Well, I think the system I am going to finally end up with will consist of components in the doors, 6x9's in the rear deck, and two AURA Bass Shakers mounted under the rear seat. (for anyone unfamiliar, bass shakers are transducers that actually vibrate the surface they are mounted to, not speakers).
So my question is this: Since the bass transducers are really only felt, not heard, will I see their "frequency" reproduced on the RTA, or should I tune assuming there is really more percieved low-frequency information than is showing on the display?
The question is really moot anyway since I usually tune by ear (butt), I really just use the RTA to find trouble spots. I haven't tried any of this yet, the qustion just struck me as curious because of the way transducers work and the fact that an RTA works off of a microphone. Since subs are actually moving air, a microphone will pick up their frequency and register it on the RTA, but a transducer is just vibrating body panels so it may not necessarily be "heard" by the RTA's microphone.
