hi! I just aquired 2 Boston Acoustics passive subs for my home studio (one for LEFT - The other Right), but I am having trouble figuring out how to wire them to my Tannoy system 1200 studio monitors. The Tannoys are being fed by a crown power amp, and each tannoy has an HF and LF bridging option. Do I hook each sub to the Tannoy in the LF speaker out? The passive subs have only speaker-wire inputs-no outputs at all! PLEASE HELP Thank YOU
