Doubling up unmatched subs

[Geoff]

I'm after some advice before I do any damage!

I have a 150W Mirage sub that sounds a bit flabby / wooly / rumbly wherever I place it.

My old Infinity BU80 sounded much tighter.

My amp has two pre-amp outs, one of which is delivering the signal to the Mirage Sub.

Will I do any damage by using the other output to connect my old sub?

I want to experiment to see if the power of the Mirage combined with the tight bass on the Infinity will improve the lower end.... but don't want to try if I'm possibly going to do any damage!

Cheers

Pairing a crappy sub with a good sub is not going to create a good sub. But you shouldn't do any damage if your receiver has two pre-outs.

Some subs only have "auto on" (no "hard" on) -- driving two subs halves the signal strength to each, and sometimes auto ons won't keep the sub on -- so you may need to boost yout sub level in your setup menu to compensate.

If you are in too big a volume for your current sub and you have old subs -- use them! Co-locating them is best if they sound different (plus it gives you the most gain).

......driving two subs halves the signal strength to each.......

Uhh, no it doesn't. This has been discussed in numerous threads here and elsewhere.

A consideration if you elect to experiment.
If you place them in separate locations, you will have two different frequency response due to room modes. Some frequencies will add together sounding very boomy, others will be in the basement, nothing as they cancel out practically totally.
You will have your work cut out for you.
If you place them in the same location, one on to of the other, well, it may or may not help much.

Thanks for your replies, folks.

I now have the courage to plug the other one in and see (hear) what happens.

I may end up using the old sub, but will resist!! After all, the new speakers are meant to be an upgrade!! My wife will go ape!!

BTW, my new sub does not have a "hard" on, my old one does.... but I still think the new one is sexier (sorry, moderator )
