Subwoofer

A sub may go to 120hz but is not usually a good idea to have one crossed over so high.

That were my first thoughts as well, but I test and compare. At the end the best results count. I have proven that it can bring subwoofers to a much higher level compared to the old fashion way of using it till 40-80hz.

Most subwoofers are too slow to be used this far and second you need a professional system to make the subwoofer one with the speakers.

At the end it is possible and brings it to a new level of integration.

A few years ago I demoed Stealth Low freqency to a surround specialist. He never auditioned something like this and he said: I think you have gold in your hands with this.

What you hear and perceive counts. I never thought that I would sell stereo with a subwoofer to be honest. Till 2008 I hated subwoofers for stereo use.

All the tests I made with Statement Audio Pro measurment did change my thoughts completely.

You need to look further to create new levels of quality in sound.

I have had many discussions with technical people who developed the best highend products. But when I asked them about the properties of the products they use at their shows they could not answer.

So I said; then you don’t understand how the sound and stage is being build what you listen at? They become totally silent. They were not able to answer the question.

I test each part/tool ( amp, cable, speaker, source, condtioner etc.) to find out which properties it owns. I work and think by Total Sound. This contains 8 parts you judge sound for.

This way you much better can control audio and adapt it like you want it. Because you understand why the sound and stage is what you hear.

Another benefit is that you are able to use all the properties a speaker owns. I have proven that I can let people hear that they are missing parts in their set. Thye miss parts of Tru-Fi. All these parts influence our emotion.

When you create an audio set with all the different parts you judge sound for, it will be more complete. People are more exited and feel more emotion during listening.

The acoustics of a room limits the quality of an audio set te most. I can garantee you that most people loose a big part of the quality their system could give in a better acoustic room.

It doens’t matter how expensive the audio system is, the room has a huge influence on the end results. So here you can win the most to create a better end result.

That is why I have done hundreds of tests in the last 6 years regarding the acoustics of a room. I have improved it over and over again. It never stops, because a perfectionist goes on and on....

Over time you have new ideas and they bring it to an even higher level. This is what I love about audio as well. Testing and shootouts is like an addiction for me. It doesn't cost me energy, because audio is like a second nature for me.

How I hear music and instruments in real, I want an audio system to sound like. It is in my head and I create it by colleting properties of all the different parts. It is like a puzzle. You combine different pieces togheter to listen what it does. When you have done this like me thousands of times, you see patterns. They make you understand why the stage and sound is what you hear.

In 2005 I had ideas how a subwoofer should integrate, but at that time I thought it was not possible. But now in 2016 it has become possible.

Time and technique go on and they give us much more tools to create a higher level of realism in sound.

Regarding cone material.....Rythmik’s Brian Ding recommends AGAINST crossing-over his aluminum coned subs at higher than 80Hz (the built-in Rythmik x/o affords as high a frequency as 120Hz, but that’s for the paper-coned sub), going with the paper-coned F12G if needing to do so. The reason for that is the aluminum cones have a lower resonant frequency (the aluminum cone itself, not the sub’s rf) than do the paper---that rf being too close to 80Hz for comfort. He recommends aluminum for higher-SPL applications, as it is stiffer than paper, displaying less cone break-up (non-pistonic behavior) at high excursion.

Ricred1, I was thinking of trying the F110s. Thought it might be a good match with my MGs. I need to look into them further.

Rwwear, I will check out the Velodyne DDs.

Thanks!
