Horning Eufrodites - help needed with boomy bass

I own the Eufrodites. They are in my living room (huge) powered by 10 watts of SET. With the preamp volume set to 11:00 the bass begins to overload the room.

There are 8 sensitive bass drivers per side, which for the most part are rear-firing. They are very dynamic. They need a lot of room to breathe. Also, I suspect that there are room nodes to deal with- you need to treat your entire room, not just the glass wall. Absorption, diffusion, bass trapping, first reflection, etc.

You can work on your other components and experiment with footers, but I suspect that none of that will have any effect on this particular problem.

Any sort of manipulation of the ports will be a step in the wrong direction. The structure and function of the ports is intrinsic to the design and voicing of this finely tuned loudspeaker.

Hope this helps!

Spiritofmusic, thanks for your advice. As you know, I live in Paris, France and therefore benefiting from the free trial offered by Spatial in the US isn't that musch of a given. As far as I can tell from their web site, they don't have a global distribution network, but I can ask them just to confirm.

Psag, thanks for your comment. Can you tell me what, if any, are the room treatments you have used in your living room?

You're right, no free trial outside US. I live in London, England, and actually took a risk which paid off.
Beyond this unit, no other room treatments, other than a woolen rug on my wooden floor between me and the spkrs.

Some back round here.

Happy Fathers Day. Tom

While waiting to see what to do with the Eufrodites, I had to listen to music, which with the Eufros wasn't possible.
Called up a local guy here who was selling some 70's stars, the Celestion Ditton 66, which I had already owned in the past.
550 euros, just as a place holder until matters are sorted out with the HH.
They arrived 2 hours later, delivered by the seller, ugly as hell.
Put them just there, where there was space, hooked them up, music on. Halleluiah.
No boom.
Fast bass.
Speakers completely, but completely disappear in the room.

Yes, the highs aren't as refined and maybe even it's time to replace the tweeter but this is 550 euros of pure musical pleasure.

Now we can calmly solve the HH issues.
