Well...if you think there are very few decent loudspeakers...try finding a musical sub...slim pickings...there is REL,Sunfire(much to hi enders dismay),M&K, hi end Velodyne...ect...
What's you opinion?
Yes, your opinion does matter. What do you honestly think about subwoofers? What makes a good subwoofer? Are we or is the market tainted by big boomy, mushy woofers and car boom boxes? Does anyone really know what a good sub should sound like and how it should perform? Who makes a truly quality product? Is quality being measured by sound or physical characteristics or both? Maybe some other criteria I did not mention? Tell me what is your ideal subwoofer? Create it. Is it a sub or a subwoofer system? The floor is open.
