Horning Eufrodites - help needed with boomy bass

Cones with sharp points are intended to couple the speaker/stand to the floor so that energy is transferred to the floor. If that floor is sitting on something like a concrete foundation, this huge mass will dissipate the energy without that much being re-radiated as sound. If the flooring is wood suspended on floor beams, that might result in the floor itself acting as a kind of sounding board. This could exacerbate a problem with booming. Whether one approach is better or the other (absorption in a compliant pad, or the fooring doing the absorption) is something that has to be tried.

But, before even doing this kind of experiment, you should experiment with room placement. You can sort of do this by random movement, or use a more systematic approach. I sort of like the "Sumiko" approach which emphasizes proper bass balance. You can find directions on the internet. When using this approach it is amazing how a movement as small as one inch will dramatically change bass response.

The next thing I would try are bass traps in the corners of the room. The primary downside to bass traps is that they are often ugly and take up a lot of room. The lower the frequency that needs to be trapped, the bigger the trap that is needed. I use double stacks of 16" ASC tube traps myself and they do work well.

I have not tried equalization in my own system, but, I have heard it effectively used in some systems.

Good luck.

Everything mentioned are steps.The first step should be grounding the speaker. Until the grounding is done there will be no stable launch pad. As for the room itself geometric angles and shapes strategically placed will redirect low frequency and help with standing wave resonance. Tom

If you listen near any boundary, floor, wall and even the ceiling you will hear more bass travel along those surfaces than travel down the more central areas of the room. The idea I suggest and one I use is to redirect the energy from those flat surfaces and scoop that energy into the central part of he room. Try to eliminate some or all 90 degree angles as mid bass punch and sound stage integration will be enhanced. Elimination of the 90's can look very cool as well.

I have some small portable angled units I put on the floor to reduce standing wave's that also add acoustic air to the performance. These can easily be added or subtracted when the family requests you to do so. Tom

Speaking of grounding speakers- I just wanted to share my personal experience, that doesn't necessarily will apply to any other speaker/system.
I have tried multiple approaches- spikes, cones (Mapleshade, Audiopoints, BDR, etc.), isolation platforms (Mapleshade maple blocks, Sistrum, Symposium, Herbie's), etc., etc.
Now my search is (hopefully) over- the best solution by far is Stillpoints Ultra 5s on Symposium Super Plus platform.
The results are simply amazing- increase in resolution, articulation. Very natural and relaxed at the same time presentaion, without any downside, as I experienced with other support systems.
The whole listening experience is at completely different level- I get involved in every single listening session, regardless of what is playing- something, that rarely happened before. And that's what counts.
Again, your experience might not replicate mine.
Should I mention how much I hated to pay the admission price? Absolutely ridiculous if you ask me! But the funny thing is- it was totally worth it.
YMMV
