Boomy sound

ruferto · 13th November 2008, 06:32 PM

Hello,

My current system is a totem arro speakers driven by one Rega Cursa(pré) + Maia 85w (Power).
I have to change the speaker position

and the sound is a little boomy

in the 50Hz.

What should i do to stop this and without losing fidelity

?
I don´t know if this is rigth.
Can i use this ?
Or should i go with an Active filter?

Hard to believe that little thing is boomy.

Have you tried adding stuffing to the ports?

Sure it's the speaker and not a room resonance? I've got lots of those (

), and they can make even a small speaker sound boomy.

sorry I don't know your speaker, but if it's a sealed box you could use this DIY.

It's a 4.5" two way with two rear firing ports

( Have you tried adding stuffing to the ports? )

Yes, it degrades (a little) the midle freq.

Initialy i was thinking of buying the storm Sub. To control the bass but it is to expensive

, so I was thinking there must be a cheaper way

.

Is it ok to try the circuit ??

(sorry I don't know your speaker, but if it's a sealed box you could use this DIY. )

Itï¿½s ported like this one.

Sorry, it has only one port.

Sorry for the confusion, I didn't know the lower port was for weight only.

"the Arro is a narrow rear-ported 2-way tower with a lower faux port for sand or shot filling and an upper acoustic port with a 4.5" diameter multi-layer mid/woofer and a ¾" soft-dome tweeter [above]."

50hz really isn't a boomy sound. Thats more like a deep low end sound.
4.5 in. speakers means you need some bass (a sub). Is there eq on this or is everything flat?
