The TRX high-frequency waveguide system provides even 90 by 90° dispersion.The integrated 16W transformer offers selectable power taps and allows the SM42T-WH to be driven by 70V, 100V, or 8-Ohm power amplifiers (available separately). Internal PolyGuard circuitry protects the tweeter without compromising high-frequency performance. A removable cover guards the 2-pole barrier strip input, which accommodates wires up to 14 AWG.

Atlas Sound SM42T Reviews
Great speakers - adjustable 4 & Ohm and wattage
I'm using the speakers in a classroom with the audio output from a projector to a small amplifier and into the speakers. The quality of the amplifier, including tone control, is important to get the most from the speakers, but they're great when matched with a decent amp. I've got no complaints at this point.
Nice punch for the price!
These were installed in a multi-room buffet restaurant. They were easy to install and are inconspicuous against the black ceiling. They are wonderful for background music and are also well designed to push the volume in the party room!
Not for music
worked with @ for sound system for bar. these are what they installed said they put these in all the bars they do. now i dont know much about music systems but I do know what sounds good.These are good for calling bingo, making them fix it but no depth for music. bad.
Big sound, small package!
Installed in my gun club as a PA speaker system, and filled the place with clear sound. Was surprised by the clarity at very loud levels! Adjustable wattage inside is a NICE feature when using some speakers in a large area, and others in small areas. Highly recommend these with a 70.7 V system. Thanks to B&H for affordable packages and FAST ship, you made me look good!
Clean sound, small package
Added a couple of these in a tight spot for some direct sound. Their big brothers took the main area and a self powered sub picked up where these little guys left off. Great little speakers. Dont expect high SPL or full range sound.
I would by this product again
These little 70 Volt speakers are really great. We use them on restaurant customer patios. Easy to install, great sound.
Easy, versatile installation. Nice looking. Good price and very good sound! Can you ask for more? I use it indoor, in my kitchen actually, for ambiance music and sometimes a little more (!)
