I'm in the process of setting up our new media room and am disappointed with the bass performance. I pre-installed wiring for four possible locations in the room, labeled "SUB POS. #".

The sub is an Energy ES-10, which I've used for more than 10 years and have been relatively happy with it.

I've tested positions 2-4 (haven't gotten to 1 yet) and they are all very weak at the primary listening position. Position 2 sounds great at the secondary listening position near it and position 3 and 4 are the same.

I've turned the sub up until it sounds as though it's being pushed too much and the primary position never gets enough base. I realize this is primarily due to room acoustics and I plan to test varying the locations, but:

1) Would a different sub help?
2) Will running room EQ, such as Audissey, help?

1) Yes. It's just an axiom that a better sub will indeed be better.

2) Yes. Audyssey helps anytime there are Room EQ problems.

And for what it's worth, Sub Position #2 angled into the corner should produce the most bass for that room.

Thanks for the help! I had given up on a response and just came back today to check :)

I'm also considering a second sub. Maybe one sub at position 1 and a second at position 2. Will it matter if the subs are different models/brands?

Never mind. I should have searched the forum first. I found some info on it.

Ok, a new receiver and corner base traps later and the sub sounds very nice. I also took your suggestion on angling the sub in the corner and it seemed to help as well.

So, for now I'll keep it :)

Still need to run Audyssey, so the results may get even better.
