Horning Eufrodites - help needed with boomy bass

Amuseb, My Hornings are less than one foot from the rear wall. Maybe the fact that the room is huge is counteracting that. It is a large room with a 16 foot ceiling, slate floors, untreated.
Amesub, if you are using the stock plastic footers they may be contributing to the problem. The speakers benefit from greater clearance from the floor. I can suggest an alternative if you need one.

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!

Amuseb, To answer your previous question: Alas they are in family room, and I am prohibited from using room treatments. So I can't claim to be enjoying audiophile sound, but then again these aren't really audiophile speakers. In the past I've used ASC room treatment products with great success.

Amuseb, I've also spent time with Marten and TAD speakers, and I would regard those as audiophile speakers. The Hornings may not have quite the resolution, bandwidth, and flat frequency response of those others, but they are more than respectable in those areas. For me, the magic of the Hornings resides in the midrange. The fact that you can also have deep bass with just a few watts of tube amplification makes these so nice for flea/SET amp users. In my room, the bass is articulate and well-integrated with the rest of the speaker's output.
