Axiom Home Page Forums General Discussion Technical Questions HTR-6190 support 4 ohm speakers

I would say that depends on your desire for bass. The lowest sub will fill the void below your speakers won't reach to, but not as solidly or loudly.

Your room you stated was 17x12 so the EP350v3 should do the trick very nicely from what I have read(must get over to Greg's for a listen) But for a real impactful sub I would go for the EP500 or 600 if the funds are there.
