Horning Eufrodites - help needed with boomy bass

Listening along, I find that the stuffing of the ports also takes some good qualities away.
The music is less dynamic, the loss of bass is also making it be missed across the spectrum, overall the sound is more itchy and less musical.
Of course this is just with the two provisional pillows tucked in the cave.
Will check the recommended materials in different configurations to see how they do.
Cheers.

The Horning website is pretty lean of info and pictures. There was a model reviewed on 6 Moons way back and it appears that they have made an attempt to couple the speaker to the floor. You do not want to damp any speaker you want to couple the speaker and provide a specific direction for the resonant energy to travel to ground. In this case the floor. If you impede the flow of energy from the cabinet it will sound different and most likely worse.

You may have an EF5 tornado in a box and your room. The energy is trapped and is trying to make it's way out and you will not be able to stop that energy that you paid thousands for. Why would you want to do that? The end result should be to make a funnel cloud of that 2 mile wide tornado and channel that energy to earth because that is what it is trying to do now. You do not want to stop that flow but to steer that energy full speed ahead to ground. Make use of all that energy make it work to your advantage make it work in one direction. I hope these concepts are of some help.

I myself design and build products that enhance the mechanical grounding of musical instruments that touch the floor. I am also a member of a company that designs, builds and sells similar technology for home and commercial audio products. Tom

Yeah Tom, I figured you had something to offer in this domain.
Where can I see some more details of it?
Thanks.

BTW, I asked Tommy about the damping materials and shutting the bass ports, he said: "all the things you are thinking of doing is against the whole idea of the Eufrodites way of working".

Using absorbent material in the ports isn't the ideal, but if the Eufrodites' way of working isn't working for you and your room, then imo it's reasonable to try to find a solution that is a worthwhile net improvement.

I design speakers too, and most of my designs have user-adjustable ports, because I can't always reliably predict in advance what the room acoustic situation will be like, where the speakers will be positioned, and/or what the output impedance will be of amplifiers they might be used with. I have one customer (a single-ended triode amplifier manufacturer) who went all the way to plugging the ports on his speakers, so they are now sealed boxes. Yeah that theoretically goes against their "way of working", but it's what works best for him, his amps, and his room (speakers up against one wall, listening couch up against the opposite wall, so lots of boundary reinforcement).

As for optimizing the type and amount of damping material, I'm afraid it's a matter of trial and error, and a juggling of tradeoffs.
