Why are only some subwoofers sold online?

We’re sorry for any inconvenience, but our Reference line of subwoofers and the 212/SX are not available for purchase online at rel.net or other online retailers; they are only available through authorized retailers. This is due to the power of these Reference subwoofers and the complexity of high-end systems with which they are often paired. To insure proper setup and integration with these sophisticated systems, professional in-person instruction and setup is required.
