4 Velodyne HGS-15's or 2 Velodyne HGS-18's?


Given this choice, which route, and why, would you go?
Building a theater and will either go with a pair of HGS-18s on either side of the center, and on the insides of the outter speakers, OR 4 HGS-15s. They would be placed in the same position, but 2 HGS-15s would be stacked on each other!

Thoughts?

For what it is worth, a single 15 would probably be sufficient for the room, but isn't 75% of what we buy overkill anyway?

Thanks for the insight.

I use a pair of HGS 18's and that's what I would suggest. The HGS 18 sounds (and tests) better than any sub I know of and I've heard and tried most of whats out there. The stacked 15's might be about as good, but would not be any better.
Good luck,

Good way to rid the house of rodents and cockroaches. I have a Mirage with (2) 12 inch drivers that shakes my house, but hey, I get more if I could. Overkill is the way to go. I'd get the 2 HGS-18's. Is 4 HGS-18's an option?

I used to have a pair of HGS-18s and loved them. Went to a pair of Aerial SW-12, but heading back to Velodyne! The 18s are great, was just curious about the 4 15's.

Funny enough, 4 HGS-8 is an option! Ridiculous, but an option!!
