i have 3 Mtx 7000 15 12ohm subs,500 rms each, and the specs for them are
Free Air Resonance Fs 31.7 Hz Volume Acoustic Suspension Vas 2.64 Ft^3 (74.9 l) Total Q Qts .61 Electrical Q Qes .65 Mechanical Q Qms 10.22
the Manufactor recommends that i put it in a sealed box 1.25 cu ft which will give me A f3 of 47 hz and a qtc of 1.12, they have other setup enclosures but this one is rec.
And i was reading about QTC and most people try to build their box aroung .7-.8 qtc's.
i am looking for real deep low bass, will increasing the cu ft to lets say 3 cu ft. of each chamber in the box and making the qtc around .7 or .8 give me that, or will the current setup do it? thank you
