amplifiers for GR Research's drivers |

|
These
are servo kits based on GR's drivers. There are 3 choices for amplifiers.
Amps for 8ohm drivers and 16ohms drivers are $10 more expensive
as additional wiring preparation is required during manufacturing
processs. A300SE has an output of 300WRMS@4ohms. Both A370PEQ and
A370XLR are new models with an output of 370WRMS@4ohms. A370PEQ
is the only model featuring a one-band parametric EQ for room mode
control. A370XLR is the only model featuring XLR input and master/slave
control between multiple amplifiers. All GR drivers feature light-weight
paper cone for higher xover points. These kits can be cross-overed
up to 120hz. However, one needs to use stereo subs if cross-overed
at above 90hz.
