Integrating Two Unmatched Subs

[Chitown2477]

I currently have a Klipsch Sub-10 and an Elemental Designed A3-300 on order. I am considering keeping the Sub-10 and running it with the A3-300. The reason is that everything I read says two subs are better than one. However, these are two very different subs. The Sub-10 does not go as low as the A3-300 so I am thinking about trying to use the Sub-10 from say 60-30hz and the A3-300 from 60hz all the way down (assuming a AVR crossover point of 60hz). I will have to get some sort of EQ for the Sub-10 to make this happen.

Does this sound at all possible? Is attempting to integrate two very different subs just a bad idea?

Otherwise, I will sell the sub-10 or save it for a 2.1 system in my bedroom.

Thanks

If I were in your boots, I'd just sell the klipsch.

Two subs can be better than one, but not necessarily.

First of all, you're going to have to see if and where nulls occur in-room.
Second, you have to compare the two subs. Is the SQ of one way worse than the SQ of the other? If so it will be audible.
Third, you need quality variable phase. 0 and 180 just might not work out properly.

You can get some benefits from two subs, but it’s best for them to be identical. The problem with mixing a capable sub with a poor performer is that the latter ends up “dumbing down” overall response to its level. For instance, you have two subs playing in the 40-80 Hz range, and only one operating in the 20-40 Hz range, obviously the 20-40 Hz range will be weak compared to the 40-80 Hz range.
