Ron’s New System

[Johan K]

The MasterSound components do look nice. With the amps the " tube protection/cages" are integrated artistically into the design, it's ingenious and looks great. The transformers are also I think a strong point in their design. Nicely potted and ample they look the part.

You have already send this twice now, and I did agree with you the first time…

But I guess I can agree once more, it it wasn’t enough the first time.. LOL.. !!

Thanks it was, lol! Not sure how I managed to send it twice.

My dear friend Robbes, a former mastering engineer, has been over to the house countless times. (Fortunately he lives only about 22 minutes away.)

He visited again last night. He proved to me that TubeTraps really do change the sound.

They do, but only do about 5% of the job needed. The problem is standing waves in the room. Tube traps work at certain frequencies by absorbing energy in such a way that the standing wave (usually a null, which is more annoying) is weakened.

But if you want to be serious about this, the thing to do is to break up the standing waves with subwoofers. Since your speakers already make deep bass, IMO/IME you really only need two subs. They must be asymmetrically placed ( in my room, one is to the left of the listening position while the other is to the rear) and not allowed to reproducing anything above 80Hz (else they will attract attention to themselves). You'll find this a far more effective means than tube traps. Once the subs are installed, you'll also find the tube traps to be more effective and useful. To be clear this isn't about emphasizing the bass as it is breaking up standing waves. On doing this, when the bass is right, you may also find the mids and highs to be more relaxed.

One of the better passive subs I've encountered is made by Audiokinesis. Normally sold in groups of 4, this sub is unlike any other I've seen in that its designed to be placed directly against the wall; handy if you have limited space options.

Dont forget that Ron also uses a couple of electrical bass absorbers in his room, probably doing exactly what you want to do with the swarm.

I experimented with that idea some years back. I don't think they do.

There seems to be a lot of positive feedback on them, but of course mostly from people that have already made the investmeent.

Which ones?
If it an active system, then they are nothing like a swarm.
But active absorption can also be a nice thing…

Ideally it is probably… passive and active absorption, and a swarm.

Bass absorbers = subs? Well placed subs will be much superior, bass absorbers are almost always a negative never heard them work without killing music

I have not heard them yet, but i know Leif uses one in his system now, so they must be doing something right.

Think it was these https://www.theabsolutesound.com/articles/psi-audio-avaa-c214-active-bass-traps-review/ but he does not have anything listed. Look somewhere in this long thread.

There CAN’T be ANY standing waves in your room Milan.. LOL..!!!

Whatever waves there is.. They must be broken down into nano particles… regarding the number of subs you have☝… ha ha ha ha !!!

For these things to work really well, you need to precisely identify the standing waves. Use a test track sample.

You'll immediately notice the frequencies with high SPL. Note the frequencies and program the active thing. Another approach is to place phase-shifted subwoofers behind your listening position. They act like a vacuum cleaner against standing waves, but without measuring, this makes little sense.
basically use the double bass array for a clean deep bass.

I have 2 extra towers with 16 12 inch drivers, maybe i should set them up as vacuum cleaners !

 

[Atmasphere]

I found it insanely easy to set up the subs to kill standing waves. Took literally 15 minutes once I had the subs out of the box, including all the hookup.

At the level at which I sometimes use the Gryphon woofer towers these days that room mode is no longer excited. So I don't routinely use the AVAAs presently.

PSI AVAAs have efficacy, Ralph. It is a pro audio product -- not a baffle us with bul%sh*t / I cannot tell you how it works / secret proprietary quantum woo-woo technology high-end audio product at 5X the price.

That is pretty funny, Ron. What do you actually hear when you use the device when playing music in your system?

Could it be that Nordic peoples have a bass fetish? It's probably related to Odin and Thor (lightning and thunder).

I have two or three specific tracks which I believe excite the room mode. When I was using the Gryphon woofer towers in full power mode with the Pendragon ribbon towers, with the AVAAs on, I could hear a reduction in "boom" and an improvement in bass resolution.

Thank you, Ron. It sounds like you found the devices effective in your old system but now your system is different so I presume the devices are off and you no longer use them. Is that correct?
