Subwoofer: should we even use them at all?

The first time I heard the Velodyne DD18 I was amazed by the roomcorrection system of the sub. He had 2 of them. There was no acoustic problem in the low freq. But the thing I found out was that the timing with the loudspeakers (Revel) was not ideal. This is caused by the lack of speed in response.

Depth is a very important part for the absolute sound. I understand that people like horn speaker for there speed and ability to play loud.

I also can play at extreme levels. With Pro roomacoustic measurement I can play as loud as I want to. My speakers have a spl of 118 db. For a not horn speaker this is quite extreme for a small speaker. But I have an extreme deep and wide stage with a physical intimate stage to die for.

I've had subs for years and just can't get it right. They sit there unused most of the time. A floorstander that can do deep enough bass is so much more satisfying.

Because most of all subwoofers do not have a response what is fast enough. This is why many people are only interested in bigger floorstanders. I had the same thoughts till 2007.

Bo1972,

What do tou use as active crossover, and how is your system set up? I'm looking into this right now. Actually posted a new thread on the Tech Talk section.

I use the crossover of the Monitor Audio PLW-15 itself. Without Audyssey Pro this subwoofer is very difficult to control

I even can choose between 6, 12, 18 and 24 db/octave

24 give the best sound.
