Our 7" would be equally at home in a high definition home audio / theater or on your boat. As all the Reference Line are a cut above, this will play down to 35 Hz and cleanly to 20 kHz. The sensitivity is 92 dB so you can play very loudly with little power. Having a 1.5" voice coil, it will handle 80 watts continuous and 300 watt peaks. It has a cast aluminum frame with a special two part coating to guarantee years of trouble free use in all applications. For home audio applications they can be ordered without grills.

This model uses a vented neodymium magnet and needs an additional ¼" minimum clearance behind the magnet.
The N7R's are efficient enough to work with most head units (cd players, tape decks, etc.) pushing 25 Watts per channel. No amp, crossovers or other gear is needed, a true plug & play driver!
If you are looking for a bit more oomph then hookup a good amp, these babies will handle 80W RMS and up to 300W.
Building a box?
Indoor use: we recommend 1/2 cubic foot ported box.
Outdoor use: we recommend 1/2 cubic foot sealed box.
Amplifiers should have a minimum of 25 watts RMS per channel for best performance. Distortion from a cheap or underpowered amplifier will do more damage than a high-powered amplifier used judiciously.
For wiring runs of 3 feet to 10 feet we recommend 16 gauge wire at a minimum, for runs of 10 feet to 20 feet a minimum of 14 gauge wire and for runs beyond 20 feet a minimum of 12 gauge should be used. Larger gauge wire is always better up to a point.
Please take this into account when placing your order and choosing shipping.
