Setting crossover on Harmon/Kardon AVR120

[Dan2036]

I'm trying to take away as much bass as possible from my speakers (tsi100) and send it too my sub(psw10) but my receiver doesn't seem to have a crossover setting, does anyone have this problem or know what to do ?

The speakers are set to large on the receiver but for two channel as far as i can see their is no way to change this... Help ?

Thanks,
Dan

I'm assuming Tsi100's shouldn't be set as large being that they are only bookshelf speakers and i have a sub
