Too much Boom from my RT16's

venomclan

Hi Guys,
I have been using a pair of RT16's as my mains for years and really like them. AT first I had them on the factory spikes in a carpeted room and they sounded great. I then moved and now have them in a larger living room with pergo type floors and glass sliding doors and mirrors. I live in a condo and custom made some speaker platforms out of MDF/concrete block, with sand in between to minimize the bass disturbing my neighbors below. I dont use a sub because I think the 16's go down enough.
My problem is that they now sound too boomy. I have them about 2 ft. from the back wall on the platforms. I have updated the factory spikes to Dayton Audio brass cones. Still too boomy.

I then experimented with putting dacron from an older Polk sub I had in the bass ports. This made the highs and mid-range have incredible tranparency, but lower midrange and bass suffered. I have heard that tipping the speakers back a bit will warm them up somewhat, but I have not tried that yet. Any suggestions on how to integrate the bass in better. I am mainly experimenting with stereo playback, but I can hear it with movies too. Thanks for your help.
Best Regards,
Jeremy

P.S. I am using an Outlaw 950 Pre/Pro and Outlaw M200 monoblocks to power them. Using a Sony 200 disc changer.

Have you tried other positioning, i.e. farther off the back wall?

You have to much reflection in your room.

Maybe try using more cloth like materials on the floor and walls, those glass doors and mirrors really create an acoustic mightmare, more so than just ordinary walls...

Mommy hold me, I am having another mightmare

Pretend as if the woofer cones extended all the way to your walls. The point where this imaginery line touches the walls on each side of the room is where you need to hang some kind of tapestry or fabric. Try it out!

Agree on the reflections...

Is the boominess present everywhere in your room, or are you just relaying what your primary position sounds like?

Hi Guys,
Sorry for the delayed response, computer problems. I mainly hear too much bottom end from the main listening position. I have tried to pull the RT16's out from the wall more, but had little change. I recently stuffed them with some dacron, and that seems to lessen the boom some. My room has a lot of hard reflections, in time i will put up more absorbant material. I think that beacuse I have a pergo type floating floor, and that the speakers cannot spike to the concrete directly, that is the cause of the boom. Anyone have large towers on a wood or laminate floor hearing too much boom?
Best Regards,
Jeremy

If it's in your primary listening position primarily, then it's likely a standing wave issue with the lower frequencies and room teatments aren't going to tame it. Speaker location is about all you have to work with unless you have notch filter capability.

I don't see the laminated floring being an issue as you seem to be on the ground floor of your home.
