Subwoofer boom is too much for me...

Mikeydee: Sure plug the bung hole. Let us know it it works on your subs. 

For music, non ported subs should be next on your list.

I switched from ported (for literally 25 years) to sealed and am much happier with the sound.

There's little, if any, substitution for not locating the subwoofer/s in or very near the rooms greatest bass modes.

Playing a low frequency test tone through a subwoofer placed at the listening position while walking the room noting areas with the loudest bass is a simple means of locating the rooms mode location/s.  

If you insist on front wall corner or next to the speakers location, good luck.  

I take it from your post that you are only running one sub.  I know that many people advocate two subs, but I have had very good results with a single SVS 2000.  Plenty of grunt when called for (by a movie typically) but pretty invisible in supplementing the bass response of my La Scalas, which are not known for great bass.
