What are the sonic differences between…

"Stealth Sub" Cannot be heard. ;)

Stealth Sub, cannot be heard, or seen on radar. I'd opt for the Velo. I have 3.

I kept my questions general because I wanted a full range of responses. (But, regardless of the forum involved, I get tired of the responses which begin with: “It depends…” or “I have not tried it, but… ”.) I already have an Infinity Intermezzo 1.2s. I have an opportunity to purchase a used Velodyne DD 18 (2007) for $1,700 or purchase a new Paradigm Sub 1 for about $2,200. This conundrum is a matter of opportunity.

My point was, if the subwoofer didn't make an audible sound and just put out the waves, how would you know which one was better? It would make a difference in that the less distorted waves would be the better of the two, but I didn't know if that could be easily determined.

The answer is that the waves are quite audible. The differences in subs are audible as well and can range from subtle (when comparing very good ones) to immense (when comparing for a example a good one to a boomy home theater one).
