I see the SRX818SP has a built-in fan. I want to use this in a studio environment. Can you hear the fan running at low/no volume?
A shopper on Jun 24, 2016
BEST ANSWER: The fan is not silent. It can be heard in a quiet room. It is not very loud, but it is clearly noticeable.
What kind of cables does it take to connect?
A shopper on Jun 25, 2016
BEST ANSWER: You can connect audio through 1/4" inputs or XLR inputs, both are on the rear of the unit.

Great Subwoofer!
Pros: Good Power Output,Great Sound Quality,Easy To Set Up,Attractive Design

Gives great bottom end for a fuller professional sound. Perfect for bands or dj's. Is also one of the lightest, if not the lightest of the 18 subwoofers in the top brands. It is easily carried by two people or even easier with a rolling cart.
