Subwoofer

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!

I understand because the are too slow, and cannot handle more. This is a limitation, you never should choose for audio tools which have limitations. Most tools/products in audio have limitations and that is why you should never buy them.

A full aluminium cone is also not the right material. You can use aluminium, but....just for a part. That is why ceramics with aluminium works better.

When you compare and test subwoofers who are able to be used till 120hz or higher they outperform the paper subwoofer with ease.

Audio needs to be used to find those products which give the best result, all other inferior products does not add anything to the world of audio!

I wish you would stop saying some subs are "too slow" bo1972. Bass is slow because it is supposed to be. I can almost guarantee if the bass is tight and fast it's because the sub is not going down to it's desired frequency. When's the last time you heard a 10' kettle drum or an acoustic bass?
Another thing. All audio components have limitations. Everything built has some limitation. A sub that works up to 120hz is easy. Making one work at 15hz is harder.
