I've said it before and I'll say it again ... I am not a pussy!
This sub is rated from 45Hz - 150Hz.
That falls in line with what my book says and I'm with you so far. This sub was designed to work with some real entry level satellites so the 1.5 mH inductor coil allows a fair bit of HF to come through. I was just wondering about lowering the upper F3 (Fu) by increasing the value of mH to 2.2mH or 3.3mH ...
Resonant frequency and Fu ... this isn't so clear but at least it's got me looking in the book and thinking instead of making asinine remarks all over the forum.
That's what I have and the book says it's a forth-order bandpass subwoofer which drops off at roughly a second order rate (12dB/octave IIRC).
That you have and it's thought provoking and educational as usual. Don't give up on me ... I will walk erect one day!
Active crossovers want external amps.
(more gear/ more money/ more space ... ain't happening right now)
I'm just looking to high pass the signal going to the regular speakers since the sub is already taking care of itself (except for the possibility of a bigger coil
) Actually I'm more interested in the discussion as an educational tool and a past time. Somehow reading the book just murders my spirit.
I'm kind of curious about the load seen by the rec'r with the sub hooked up in parallel as opposed to what it would see if I used speaker connections 'A' and 'B'. I think it might be the same thing with a nominal value of ~ 16 Ohms but that's a guess.
Thanks for the response and for helping me kill a whole mess of time typing out this response ... the research ...
