Home audio SPL help

[bmrbch]

Hello all,

Amateur and budding audio freq here. I've set up a new system and would like some insight into how I can optimize it a bit. Attached is my SPL and looking to see what I can do to improve it. The 30 Hz peak is VERY noticeable as the entire place shakes like the stay-puff marshmallow man is inbound (cool, but not great for movies etc). And the 400 hz dip is very noticeable during a frequency sweep, but I hadn't noticed it other than noticing things are a bit "off" during listening. My biggest beef during normal listening (both music and HT) is that the volume needs to be adjusted regularly. I think it's the peaks and troughs depending on the range of sound (ie lower, bassy songs vs higher or explosions vs ambient high effects).

My system/setup:
Room is 20ftx40ft with 15ft ceilings. Mostly brick and hardwood.

System is Marantz SR7007 with Audyssey MultEQ, DefTech 8060 towers, 8040 center and a SVS SB-13Ultra sub. MultiEQ XT on, Dynamic EQ on at reference, crossovers: front:60Hz, center=80hz, Surround=150hz

Thanks for any help you can give.
-Brian

My first thought is 'What have you got for room treatments?'

Hardwood and brick will not cancel out standing waves. I am far from an expert but I think a few sound panels to make the room acoustically 'better' will gain you a great deal in evening out your readings, especially in the high frequencies.
