How to add a subwoofer to a 2 channel stereo


Hi, I run into a strange issue here. I have purchased an used Mcintosh HT2 subwoofer. It is a great passive sub. However, If I run this sub together with my tower from same amplifier, this sub sounds great, but not that powerful. However, if I run as bi-amp, and power this sub with a dedicated sub amp, I can hear and feel all the punch, but the sound is not that solid. Did I do anything wrong? Help!

this is why a good powered sub or 2 makes life (and the music) better and easier

I believe the HT2 may have been designed to be used with McIntosh amplifiers/receivers that use their autoformer output stage which has 8 and 4 ohm positive and negative speaker binding posts. 

If your amplifier only has left and right + and - binding posts and your stacking both your tower speakers and the subwoofer cables, this may be responsible for the lower output your hearing.

Refer to the McIntosh HT2 manual as well as a McIntosh amplifier manual or contact McIntosh directly for assistance.
