Main Advantages of InwallTech Speaker Selectors are:
Removable Speaker Connectors (No Extra Cost) –Easier Install and firmer connections
Heat Sink Covered Resistors (No Extra Cost)….other makers provide inadequate cooling –Higher (honest) Power Handling
Venting ABOVE and BELOW Resistors (No Extra Cost) — Smarter design = Higher power handling and longer life

The SS4R is a resistor based, automatic impedanced matching speaker selector used for connecting 4 pairs of speakers while maintaining a safe impedance load for your receiver. Each pair of speakers can be turned on or off independently in any combination without concern for amplifier loading.

-Isolated left/right circuit grounds provide safe connections for amplifiers with floating grounds or bridged configurations
-High quality construction throughout provides excellent reliability,
accurate noise-free switching and years of trouble free operation
-Rubber feet prevent scratching and keep selector in place during operation

    Speaker selector works really well. Had an issue at first, but the company resolved it quickly and I couldn’t be happier.
    Thank you, Inwallstore.

    Works great but the little rubber feet just fall off. Not really a selling point in my opinion.

    I’m a professional installer and I’ve used these when I need to drive multiple speakers from a single amp. The phoenix connectors handle 12ga wire, and combining 4ohm and 8ohm speakers is no problem, volume seems to be well balanced and the box is audibly transparent to me. If you don’t need volume control per-zone or have other volume controls installed, these work great.

    Great product & service

  5. CM

    Very impressed with the solid build of the case and paint job. So far it is working as advertised, but I have only tested it with one pair of speakers to date. Only disappointing thing is that the rubber feet are just cheap glue on rubber pieces which fell off after a few minutes in use. And there are six positions for them to fit, but only four were attached (unless the other two had already fallen off). I am only commenting about this because the rubber feet are listed as a feature in the user manual, so had to laugh about that.
