I use the HD-6 mids in my 3-way speaker system. With a full sound deadening treatment, EQ and time alignment your speakers could sound 100% better. You can turn HD-62 into an MX-Designs 3-way system with one of the upgrade kits, such as this one: CDT Audio MX-2UK 2" | Easy Way Electronics The crossovers give you more adjustments to tune the speakers than what you have now.
