Horning Eufrodites - help needed with boomy bass

Try using mechanical grounding devices under your speakers and components they work. They direct mechanical resonace and energy stored within the component to ground. Less boom and blurr.. Tom

It sounds to me like the speakers are getting a lot more boundary reinforcement in your room than what the designer anticipated, and reducing the amount of bass they put out may be a lot easier than changing your room's acoustics.

I have zero experience with the Eufrodites, but eyeballing the speaker, I see four woofers and a big port, and the description sounds like it's a transmission line variant. You might try attenuating the port's output via damping materials. Open-cell foam, polyester batting, a bath towel, whatever you have on hand. The idea is to find out if this general approach makes a net improvement, and then you can fine tune it from there. You might get better results (tighter bass with decent impact) by solidly sealing off the ports completely, turning the bass system into a sealed box, perhaps even with that damping material inside.

Duke,
That is a good idea for a ported speaker.If that does not work or if it partially solves the problem would some degree of bass absorption benefit him?

These have been around for 15 years or more and they work.

MB Quart had them as well as Audio Concepts

Hi,

So further positioning trials have somewhat improved the boominess.
And then, following Duke's post, I stuffed towels into the woofers' ports and I think this is making an important contribution to the battle!
For sure, right now, I can listen to music and enjoy it.
Big step forward. Thanks a lot.

What material would be best to use for an appropriate stuffing?

Other than that, from the positioning trials I came to spread the speakers even further apart from each other which opened up the sound stage and brought in a lot of space between the instruments. So way to go for this collateral benefit.

Tom, how would you reckon the Variovent be installed in my speakers?
It seems that large speakers require a few of those. How would that be done, any idea?

Thanks a lot to all the contributors so far. It's helping a lot.

Regards from Paris.
