Hi all,Im a noobie here.My first question.Can this circuit of bits and pieces from Elliott Sound Products,work for a subwoofer? First stage a buffer,then a 36dB lowpass,a x2 gain stage and a Linkwitz Transform. The link to the image,is a crude website I just knocked up 10mins ago.Hope its okay?If an image of an angel comes up,click on mikes. Thankyou http://irvingsallsorts.mysite.wanadoo-members.co.uk/
