Help with crossover
« on: 19 Apr 2009, 08:59 pm »
We need help again on our speakers. This time we need a starting point on our crossover and have no idea what to do. A schematic diagram would be amazing if thats possible. We have a 6 in. diameter M130 woofer and a 4 in. diameter Vifa tweeter. Here are the parameters we have for both.

M130:

Resonance frequency-fs   53.0095 Hz                      V-C resistance-Re   5.7 Ohm
Cone Mass-Mmd   6.6331 grams                              V-C inductance-Le   0.3127 m*H
Dynamic mass-Mms   7.1655 grams                         Force factor-Bl   5.5019 T*m
compliance-Cms   1.258 mm/N                                Mechanical Q-Qms   2.4715
Mec. resistance-Rms   0.9656 kg/s                          Eletrical Q-Qes   0.4494
Equivalent volume-Vas   16.1225 liter                      Total Q-Qts   0.3803
Linear excursion-Xmax   3.0 mm                              Reference efficiency-no   0.5183%
Effective cone area-Sd   95 sq cm                          Efficiency-SPL   89.1454 dB-1W/1m
                                                                        Sensitivity-SPL   90.6176 dB-2.83V/1m

Vifa:

Fs   1450Hz
Power   60W
Sens.   92db
Impedence   6ohm
Re   4.6ohm

I suggest a google search for GR Research M130 projects.  You did not identify the Vifa tweeter.  Second, I  would contact Danny at GR Research and run this by him.

Our tweeter is a VIFA D26SG-05.
