How to make LSi 9's less boomy

punit

I have a stereo audio set up using Rotel RB1080 amp & Lsi 9's. Until recently they were set up with a distance of 20 inches from the walls but i had to shift residences & the new room where the speakers are placed is quite small (as compared to the previous room) & i can place them max 10 inches from the wall (& one speaker is at the corner wall).

This has made the bass very boomy. With other rear ported speakers the manufacturers recommend placing foam plugs in the bass ports to reduce the bass if needed. But that option is not available with the LSi's due to the Power Port.

So any suggestions to make them sound less boomy ? (for ex. will placing a carpet on the wall behind the speakers help ?)

Thanks

Also one more thing. In my old room the Lsi's were placed on speaker stands whereas now they are kept on a wide table( the hieight of the stands & Table is the same). Maybe the Bass is reflecting off the tables surface ?

Try cutting a piece of carpet to match the footprint of the speaker or setting the speakers on sorbothane blocks. The "boominess" may be resonance from the table you have them sitting on. If that doesn't work, try hanging some heavy fabric on the wall behind the speakers.

My Pre amp has Hi-Mid-Low eq controls. Reduded the low eq control by about 20%, sounds fine now.

Thanks for the suggestions.

Upgrade the crossovers. Also try moving them a little further from the wall.

maybe a sound panel at the rear and sides will help.

The best way to make them less boomy is to sell them and get the Lsi7's. And that's if you dig the Lsi line , other then that it's time for new speakers.
Honestly I think the Lsi9's are the worse speaker in the Lsi line. I owned them along with the 15's Center and FX's . They are exactly what you say here , they are very boomy. They seem like they try to play to low and do a bad job at it.

If you are using a surround receiver , cut them at 80hz and let a good quality sub handle everything else.
