This driver was used in the Rockford Fosgate R300-10
car subwoofer. You can still find them for sale if you do a
search. The system used a 1.3 cubic foot sealed enclosure with
a 300 watt RMS amplifier. Reviews are very positive for this
unit. This is a great sub for people who need some extra bass
in the car, but don't have a lot of space for a big box.

Comment
"This tweeter measures very
well and is by far the most dynamic non-horn-loaded tweeter
that I have encountered thus far with whopping 96db@1m/2.83v
senitivity coupled with excellent power handling and best used
with a 3Khz crossover." Steve Sedmak |
