one 12in sub or 2 8 inch subs

Hey I have found that even though bass is omni directional that the soundstage presence is improved if the bottom end is as balanced as the mids and high frequencies.
Not to steal your thunder but I am currently running 2-8" self powered subs on both left and right channels. 2- left 2-right. 200w each side and adjustable.
I find the sound stage to be more appealing but YOUR ears are the final decision makers.
Hope this helps.

Hey just curious... Which other speakers are you runnin with the sub.
That will probably help you decide as well. Just an after thought.
