Subwoofer: should we even use them at all?


Dear Community,

For years, I looked forward to purchasing a subwoofer. However, I recently became friends with someone in this field who is much more knowledgable than me. His system sounds amazing. He told me that subwoofers should be avoided because of the lack of coherence that inheres in adding a subwoofer. What do you guys think? I currently use Verity Parsifol Ovations.

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.
