Bass boom

Posted by: Tristram on 18 November 2002

I've got a problem.

Just moved to a new place and the speakers are not realy working as they should. The set up location is the problem, but mostly because it involves an alcove, and a floor that seems to be less "solid" as you move out of it. The alcove creates some obvious constraints although it is fairly large. I've got NBL's and the boom at times is unpleasant. Probably moreso for the other residents in the building. I don't have any other location options so I have to work with what I have.

Has anyone used those pad type sound poles that are in stereo shops to reduce reasonance? I'm wondering if they can help solve the problem.

Thanks in advance. tw

Sound Bases by Mana certainly help.

NBLs? They are very serious speakers, I do hope you've got a minimum of a CDS2/52/135s to drive them, cos that is what they need, imho.

Regards,

Steve.

It's just a pleasure to hear music as it was intended to be heard.

If you refer to these plastic/rubber feet, i cannot recommend them. I don't have any NBLs but compact speakers on massive stands. I once put such feet between the stand levels and the speakers: bass boom got worse! I have the impression that anything made of plastic or rubber even contributes to bass boom instead of reducing it (on any kind of floor, concrete or wooden). Try something rigid, like spikes (,or Mana?).

I've tried three things that help bass boom:

1) going active
2) Mana under the speakers
3) Changing to smaller standmounters

Sounds like you have a problem with speaker siting!

Try moving the speakers further away from the wall ands away from each other and see if the problems dissapear.

I have a pair of Ruark Equinox's and when they are placed too close to the rear and side walls they can really boom but careful placing of them can really open up the sound. Not just in the bass department but in the midrange as well.

I had a similar problem with Proac Response 2.5.

My solution has been a combination of Nordost Titanium pulsar points (in place of the speaker spikes) and Mana sound bases. The result has been spectacular with an almost total elimination of 'boom' and a huge increase in soundstage.

I experimented with spikes instead of the Points but the result was far inferior. It is particularly easy to eliminate all speaker movement using the Points and this absolute stability seems to be very important to the result.
