Bass in a basement

[rpalme1]

I have a PSW505 and M 70's on concrete floor. All the bass seems to go straight up thru the house. I do not have much bass sound in a seated position. If I stand up i can here and feel alot more.
Any suggestions on placement to help this?
Thanks for any help. CP

Stack your sofas and chairs on 5 foot risers??? JK!!! What size is your basement,any carpeting on the floor at all? What do you have on the walls? Maybe the ceiling is the path of least resistance for the sound waves?

it is hard to get bass that you can feel when you have concrete floor, I know.

You need to have lots of power to get earth rumbling with a concrete floor. I would suggest trying a Sunfire and if that does not work two.

If you can put your sub in your seating position. Then crawl around on the floor until you find the spot that has the most/cleanest bass and place your sub there. You may have to move it around to get it dialed in. You might also want to play with the distance for your sub in the receivers settings. I had my sub right next to my left main, the left main was set at 13' in the settings while my sub had to be at 9' to make the speakers in phase with each other.

Start with this:

* Subwoofer in the corner of the room, opposite the listening position, also aimed at the listening position (if front firing).

* Front speakers straight ahead or aimed very slightly at the listening position, ports 2 inches or less away from the walls (but not fully against the walls).

At this point, the bass should be very pronounced at the listening position, it will have even more presence at the corners of the room and up near the ceiling.

Once that much bass presence has been confirmed, start moving the front speakers and the subwoofer further away from the walls and experiment with different angles until the bass at the listening position sounds the best. The bass will still be even stronger near the ceiling and in the corners of the room. (Good way to check if bass levels will shake walls or even an upstairs floor.)
