Are big subwoofers viable for 2 channel music?

Wow check this out from SVS... they seem to believe in the big subwoofers = potentially more distortion due to lack of control principle.

"Acoustically, subwoofers with 15-, 18- and 20-inch drivers are more susceptible to boominess and distortion compared to subwoofers with 10-, 12- or 13-inch drivers because the pistonic movement of such a large surface area is harder to control. Poorly designed big subwoofer drivers with inadequate motors don’t produce accurate bass and struggle to start and stop on a dime. This results in low frequency output that can sound smeared, boomy or bloated and detract from the convincingness of an audio experience.

It’s even possible for a subwoofer with a 10- or 12-inch driver to outperform a subwoofer with a larger driver if the motor magnets in the smaller subwoofer can generate greater force and exert better control over the driver. It’s also the reason why a subwoofer’s driver size can be overrated when determining the overall performance. Put simply, a big driver is harder to control, and offers no guarantee of greater SPLs or deeper bass than a small subwoofer."

 As they roll out their 16" subs... I'm a fan of SVS, but c'mon.

How SVS fixed it... 

"The turning point for the 16-Ultra Series subwoofers involved several key innovations. The first was an 8-inch edge wound voice coil, the largest ever deployed in a consumer subwoofer. The massive voice coil girth allows the woofer to exert complete control over the 16-inch Ultra driver and remain accurate and distortion-free with pinpoint speed in transients, even at reference playback levels. Four of the heaviest toroidal ferrite magnets ever used in a subwoofer generate unprecedented levels of magnetic force and machined motor elements produce astounding levels of low frequency output with minimal distortion. The cone material consists of a premium fiberglass resin composite that moves extreme amounts of air and sonic energy without ever flexing or losing control."

As enthusiast enamored with our equipment, in our room, in our opinion we have to be careful not to be closed minded. I do not believe most enthusiast start with a great system. Great systems usually evolve over time. Most enthusiast come to a forum seeking advice and/or to learn from other people’s knowledge and experience.  

     We read, research, hear, or hear about a new way of doing things and we explore the new information. If we are open minded our joy of the hobby and our systems are improved. If we are determined to be closed minded, we do not grow. If we are determined to be closed minded we miss out on possible system improvements.

     If we insist our way is “The” only way we hinder/limit our own growth. If we openly criticize equipment and experiences with no credible experiences we could possibly hinder the growth of others. In those cases we should always remember to include “In My Opinion/Experience” etc.  
 
    I read more than I post. I try not to criticize anyone’s personal preference of speakers etc. I have heard multi-subwoofer setups. I actually considered purchasing a SWARM setup. I have experimented with a third subwoofer in my room. I have also experienced sub-woofer systems capable of Ultra Low Frequencies (ULF). I am very happy with my system but I am also very aware it can be improved.

     None of our systems are perfect. None of us know everything. None of us should attempt to invalidate the experience of someone else based on our own experience. The goal should always be to learn more/understand more. The goal should always be to improve and increase our enjoyment of music and the music playback systems. Some have forgotten this, others never knew it.  

Very well put (indeed above quoted post of yours should be a "sticker" on these pages), and I'm not saying this as someone necessarily complying in my actions with what you point out. I just know of it to be a commendable approach, and one to strive for.

I think it's a little disingenuous of SVS to imply that they're the only ones that know how to use a big driver.
