Help choosing dual subwoofer

tapotti

Hi,
I have a VTF3 mk4 Hsu research sub.
I want to add a second sub, but I'm not sure if I should get a second mk4 or just go for the vtf 15 mk2
They don't sell the mk4 online anymore. Opinions?
Thanks.

                        Will the old and new subs be positioned the same physical distance from the listeners?  If so, having two with very similar performance capabilities is the best approach.  If you have latitude with regards to placement than you can frequently get away with having disparate subwoofers, provided you balance them carefully.

                        My sub is located in the front right corner of my room, about 12 feet from listener.
My second sub, I wanted to place close to the seating in a back corner, with the intent of "feeling" the bass more. So the subs would not be equidistant from the listener.

                        How big is the room? What is it you are wanting from dual subs over a single? Usually you want to get a second identical sub if possible. In this case the closest would be the updated version, the VTF-3.5.

                        My theater room is 13 feet L x 15 feet W x 10 ft H. The room is not an enclosed room.
I have my VTF-3 mk4 in the front right corner.
I wanted to place the new sub next to the seating with the intent of "feeling" the bass with the low frequencies. I am about 60/40 movies/music. I thought that the VTF15 mk2 would be the best choice because of its output below 20 Hz. Given that it is only 70 dollars more right now, I have no concerns regarding budget.
Thanks.

If the room is not enclosed than you can expect some output to be lost into the area not associated to your theater room.  There's nothing that can be done about that I'm afraid, it's just how physics works.

The sub with the least capability needs to be closest to the listeners.  That way proximity helps to overcome any performance variation between them.
