hi all.. i am putting together a small system. basically i'm feeding 300 rms (underrated watts) to two Kaption 10's (old school ones)..
anyway i am looking into a Harrison PFMOD subsonic filter selectable to 20, 25, 30, or 35hz @ 12dB/octave: http://store.hlabs.com/pk4/store.pl?view_product=12
my 2.072 ft^3 enclosure is tuned to 35Hz. what is the general rule for where to cut off the frequency band? right at the tuning freq? or could it be set a bit lower? these subs are rated for 175rms each, this amp will match that plus a bit extra, so they will be at their power limits. i plan to set my gains conservatively and would like to have my filter set so that they will be safe from playing frequencies low enough to damage them.
does this subsonic filter look like a decent one? i've been researching others but i am trying to keep power draw to a minimum so i hope a passive one like this will do the trick.
any opinons are greatly appreciated
thanks!!!!
) but i find it hard to find info on what gauge wire to run to the SoundStream BX-10 and how much current it uses. i only have a stock 95amp alt and stock battery in my Explorer which is why i was thinking i should go with a passive filter rather than a processor with a subsonic filter that will draw extra power to operate. my amp has 60amps worth of fuses and it's not a Class D so i'd say it will draw quite a bit from my stock system as it is. depending on what gauge wire to use for the BX-10 and how much current it will draw, for the extra $10 or so it might end up being more useful than the PFMOD. only drawback would be the cost of extra wiring but if it doesnt use much current i could shell out the extra $$ for the BX-10. but all in all i dont THINK i need all the bells and whistles that the BX offers. all i really need is a subsonic filter, i dont know maybe if i had a BX i'd end up liking it lol.
