dual speaker

Does anyone got information one the thecnic that consist of putting two speaker face to face.

I've recently trired it with two very low quality 10" woofer and the bass was very boosted But the sound was horrible(well nearly).

Does anyone got info on that.

P.S. d'ont mind my english.
do you mean isobaric?


but the way you describe it, it's maybe a 'clamshell' isobaric:


...but maybe you just put 2 speakers face to face?

usually, one gains a smaller cabinet, some SQ, but no real gain in ouput level if you go isobaric. (actually needs twice the power than just 1 driver)
