2 type Rs vs 4 type Rs

Alpineuser New member Username: Alpineuser Post Number: 1 Registered: Mar-05	Posted on Sunday, March 06, 2005 - 06:14 GMT I currently have 2 type r 12s dvc 4+4 with a jbl bp 600.1 pushing them. Was wondering would it be better to add 2 more type rs with another 600.1 or sell what i have and buy something different
