The key to Quadraspire versatility is that you can not only add/remove levels, but also swap different column heights should you wish to increase or decrease the height of a shelf. You can also convert a Quadraspire Amp Stand to/from a rack shelf.
Columns Sets may be purchased in lengths of:
Q4 Column Sets are $99/(includes 4 Q4 columns)
SVT Column Sets are $199/(includes 4 SVT columns)
