Subwoofer

Regarding how "fast" a sub woofer responds. I do not buy into many of those points. I believe it has more to do with driver motor assembly and the amplifiers dampening factor than cone material and overall weight. I often prefer paper and infused paper for its tonal qualities, never much considered its weight. But have had subs that employ poly and aluminum cone materials that did very well at reproducing natural tones and textures. I never detected any being inferior in terms of pace.

There are way too many factors at play, more than I care to try listing. To sync the subs to every set of mains would be major a feat in itself I would imagine. I would bet most if not all to be off if even by a millisecond or two. Such a minute difference that you wont be able to detect any difference without the use of the multi thousand dollar measuring devices anyway.

Many brands still use drivers with material what is too slow. Even EQ will not solve this limitation.

I also use Ultra Stillpoints, which make a huge improvement in timing and accuracy. Same about using a 100% silver interconnect.

At the end each part you can use to improve response/timing are essential to create a stunning integration.

Because most subwoofers and the way people use them are still too slow for a optimum level of integration.

In the past subwoofers were used more often for multi-channel, but.....these days you have the option even for stereo use to create a superior level compared than any system without a subwoofer.

In 2005 I thought this was not possible. But now I can say; It is possible. This makes stereo so much more appealing to listen to music.

When you still believe paper is the way to go for subwoofers, you would be a fool. To a few Velodyne owners I have proven that their subwoofers are too slow. 

You need to make audio understandable for many people. Shootouts and explanations why the sound is what you hear is the essential key to bring people to a higher level in sound quality.

Even with a 4000 watt amp, a paper driver is still slow in response. Doesn't make sense. 

You need to look further to focus on the best response/timing possible. To create this each part needs to be used to the max. 

Some of the leading speaker manufacturers such as Scan Speak.employ paper, I suspect for good reason. Name calling is childish, I’m not here to debate with the likes of that. Or narrow mindedness. As far as material goes, no one can ever prove which is superior because it comes down to a personal presence, as do many things in this hobby. Enjoy your shootouts.

On another subject, I'm still looking for your comments on the Monitor Audio PL500 speakers?
