It really depends on your priorities. Cleaner records or a more balanced and deeper foundation for the music. I am sure there are many who disagree with me but IMHO 2 subs should be mandatory for a stereo set up. I have the Spin Clean and earlier the VPI 16.5. Apart from ease of use, the Spin Clean is a great bargain. No static is a major plus for the Spin Clean.
The 2nd sub would be the same model REL ?
