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

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!!

I'm using 3 HGS-18s across the front of my main theatre. I tried the 15s as well. I highly recommend the 18s over the 15s for a more literally 'stunning' result. Was using M&K 5000s and 350s. The 350s are on the sides and rear channels now and the 5000s are in the master bedroom system. Room tuning/treatment became more critical with the larger driver Velodynes than the M&K dual 12" design.

I wouldn't stack the 15's and I would suggest putting the subs outside the main speakers. Almost no manufacturer reccommends the inside the main setup. If you want four subs put them in four corners. The Velodyne 18's are great so use em. I personally have two Revel sub-15s and they fantastic both for music and HT. In the scene in Matrix where the helicoter hits the building these things are bone jarring.

Get the 18's and put them in corners (or close to.. if you cant tame them) and make sure your homeowners ins covers
structual damage from non-natural sources.

Get a Earthquake Supernova MK-IV 15 or a pair and get ready to be stunned.

I had a Velodyne HGS-18 and thought it was the best sub for a HT/music combo. I happened across a deal on a Earthquake Supernova MK-IV 12 at a divorce sale for only $400 so I picked it up.

WOW!!!!! It was so much better than my Velodyne that I placed the HGS-18 up for sale a week later.

The Supernova 12 is just stunning in it's shear power that it makes some movies scary. It is not as good as a REL for music but just as good as the Velo.

I finally feel vindicated by the glowing review from Stereophile GTHT. No one ever believed me when I said that this sub is better than the HGS-18 until they heard it themselves.

The Supernova MKIV 15 is better than the 12 I have but I don't think my house could take anymore pounding.

I do like the idea of using a pair of subs since the room I have responds much better. I used to use 2 subs for left and right and the Velo HGS-18 for the center/surrounds/LFE but since adding the Earthquake I only use it and a old Kinergetics research sub which is hidden under the coffee table in the center of the room.

The Earthquake Supernova subs are the real deal and you would be making a mistake if you don't compare it to the HGS-18. I am sure you'll be a convert too and save a lot of money to boot.
