Looking for a sub to put in my amps loop function
I recently picked up a Peachtree Nova 150 to drive a set of Dahlquist DQ-10 loudspeakers and would like to add a subwoofer into the amps loop function to take the load of the 80Hz and below off of the amp and DQ-10s and onto the sub. I was looking at the rythmic audio F12 but would like to know what other options are out there. Thank you for any and all responses.

@contuzzi, Please read the Vandersteen 2WQ manual: https://vandersteen.com/media/files/Manuals/2wqmanual.pdf You can insert the capacitor to the loop and connect a subwoofer to preout or speaker output as long as the subwoofer has a contour opposite of the low frequency 6dB/octave roll off induced by the capacitor. |
6 dB/oct low pass is too slow for a sub. You will have it running up into the mid range. IMHO 12 dB/oct is the slowest I would use.For example, if the loop input impedance is 10kohm and a 0.2uF capacitor inserted to the loop to create a 6dB/oct roll-off at 80Hz, what you need is the subwoofer can provide a contour inverse of that 6dB/oct roll-off, above 80Hz, it dosen’t matter if the low pass is 12dB or even 24dB. |
