How to hook up subwoofer to amplifier with no sub-out? (1 Viewer)

[BlaineG]

First of all please forgive my stupid question, i have searched google and the forums with no luck. I have a marantz pm7200 amplifier hooked up to a marantz dv6500 dvd player, connected to 2 dynaudio audience 52se's. Anyways, a friend just gave me his canton as 22 subwoofer and i cannot for the life of me figure out how to hook the thing up to my amplifier. Do i need some type of extra equipment to hook up a sub to my system? Thanks in advance for any help!

Blaine, does the sub have high level (speaker) input/outputs?

if it does you can connect the speaker output from the amp to the sub, then out from the sub to the speakers. this will also allow you to use the sub x-overs to blend in the speakers with your sub. If the sub doesnt have speaker outs, you will need a Y connector to split the speaker signal

if the sub doesnt have high-level I/O, you may need to connect the sub using the tape monitor out from the amp, but blending the sub in may be a tad difficult.

nice speakers, BTW

Thanks for the reply feisal i hooked it up like you suggested and it worked great. I originally thought that was how it worked but i was too afraid to hook it up like that for fear of damaging my speakers for some unknown reason. Also, am i going to get any degradation in sound quality by running my speakers through the sub? And finally i have no idea how to adjust the sub to the perfect settings so it is not too boomy, does anyone have any links to a guide on that? Thanks again for the help i really appreciate it!

as a rough guide you can set the sub x-over above where your speakers start tapering off at the bottom end (looks pretty low, from here. why do you need a subwoofer again? ok, you got it free... )

if you really want to fine tune it then a SPL meter will help to plot the FR curve so you know exactly where to put your xover
