BassMunky Posted December 27, 2011 Report Share Posted December 27, 2011 How Can you adjust the subsonic filter. You did not adjust the subsonic you can do this man Subsonic filter is to roll off the low frequencies under the resonant frequency of your subwoofer if you are using a ported design because under the port tuned frequency the woofer excursion is no longer controlled and will bottom out very easily. This does not have happen if you have a sealed box as the woofer excursion is always controlled by the air in the box. For your sub, 30Hz would be about right but other forum members may have other responses. As for th 80 Hz LPF, it depends on how much bass your mids can take. If you have really good mids you can set the LPF 60Hz or so, and then the High Pass Filter for the Mids also at 60Hz. Thats where I set mine. Experiment with yours. The extra bass comming from up front is awesome. I do have very high end mids and 300watts a side however. the "turn counterclockwise until voltage is .707 x max voltage" is setting the -3db point since power is voltage^2, .707 x.707 =0.5 or half power, the -3db point. (.707 = 1/square root of 2) So for the LPF example, the procedure sets the -3dB point at 80 Hz. This would be more accurate than looking at the frequency dial on the knob. you need to have an AC RMS voltmeter. Most DVMs read AC volts RMS.

JEFFYBOI Posted April 20, 2015 Report Share Posted April 20, 2015 Maybe i missed something... Does the CC-1 match subsonic filters or how does one do so when gain matching 2 amps? I am pretty sure you would want both filters set at the same level.

Karkov Posted April 22, 2015 Report Share Posted April 22, 2015 Maybe i missed something... Does the CC-1 match subsonic filters or how does one do so when gain matching 2 amps? I am pretty sure you would want both filters set at the same level. You would set each amp separate as far as SSF's go, but you can set each one to the EXACT frequency you want them at. When setting *Subsonic Filters* you set each amp individually but they will still be identical and not play below XX frequency. It comes with two discs that have a track for different frequencies so that's how you set them. No guessing. No using a DMM. No math involved. Super easy, super accurate, super worth it IMO> 1 Quote 2007 Chevy Tahoe (SOLD) 12 ~ FI Audio X series 10" w/BP option 2 ~ DC Audio 5.0K @0.67 3 ~ DC Audio 5.0K @1.0 2 ~ PPI 3 way sets (not installed yet) 1 ~ RF T400-4, 1 ~ RF T600-2, 1 ~ RF T600-4 4 ~ CT Sounds 5.25" Strato comps (rear fill only) 1 ~ XS Power D4800 1 ~ XS Power D3400 8 ~ XS Power XP3000 160 stock alt, Mechman 370 Elite, 185 DC Power 320+ Sq.
