Two subwoofers

Simple question: If you have two subwoofers in the same system properly placed apart and balanced in the room, should they be exactly the same models, amp types and and have matching power outputs? Is it possible if you have two different types that they could be out of sync? For example, if one is a class AB analog amp at one power output and the other a class D digital amp at a higher rated power output, could they be out of sync even slightly?

I am assuming when you mean out of synch, you are referring to out of phase? I am guessing one sub set at 180 and the other 0. I pondered similar issues a few years ago. My old 15" sealed 1000 watt sub watt (B&W Nautilus ASW 850) has been a workhorse in my system. I wanted to get a replacement but of course they are not made anymore. After researching and doing comparative analysis (Internet sources and manufacturer products), I opted to get another 15" 1000 watt sealed sub, from HSU. It had all of the basic functionality of the B&W in terms of specs and controls. It was easy to blend both of these subs with a Velodyne SMS1 sub eq. Excellent room response. I have them configured directly to the right and left of the main speakers. You will need to level match them first in order to ensure that the volume is the same for a given output.

Good luck,

Where you get the SMS 1's? It is not for sale on the Velodyne website anymore. I want to use two for my setup.
Thx.
