I'm aware of the pitfalls of 70v systems, where I'm getting hung up is how (from other postings) there is virtually no low frequency information below xx Hz depending on what transformer is used. That being said, if you use a...
to feed the subs, AND there is virtually no LF information present at that point, what good are the subs? It's like connecting a fire hose to an empty hydrant.
Hello,
I don't know where you've gotten the opinion that there is NO LF information present when using these transformers... there is definitely less LF, in typical gear, but, it is not non existant. Secondly, Subs designed to work with 70v or 100v systems have larger transformers, they will reproduce much of the LF.
Demo a few different Subs.
If you really need to shake this dance studio, then, you may need to step up to the low impedance gear. (and you may need to double, triple or more your budget) But, since you're already into the 100v gear, try adding some demo subs. It may be exactly what you're looking for.
Try it... then, come back and tell us what you think.
