Hi  - A quick question about connecting a subwoofer to my SE34.2I / HDT setup.  I know I’ve seen the answer to this before but cannot find it in the archives.   There is some discussion in one of Steves papers about the WO sub, but I just finished the HDT’s and have to take a break from speaker building for a while.  I thought I saw that this can be done using the speaker level inputs/outputs (pic attached).  How is this accomplished?  I'm a slow learner, so the simplest method is preferable. Thanks so much.

Thanks Zygi - So just to be clear, run a set of wires (+ and -) from either speaker to the speaker level input on the sub.  The speaker level output on the sub goes to where?  I'm just a little confused by your last statement "I wouldn't however, run the wire from the integrated amp to the sub amp, and then run a set from the sub amp to your HDT's"  

Any sonic advantages/disadvantages to this route.

Thanks so much

The L & R sub amp outputs are connected to the L & R sub amp inputs through 2 large capacitors.  This forms a 6 db/octave high pass filter at about 100 hz.  This will block the lowest frequencies from ever getting to your mains (HDT's).  This will substantially reduce the amount of work your mains have to do, and will prevent the mains from "fighting with" the sub at frequencies below 100 hz.  Some people prefer this (like me).  Other people prefer to run their mains direct (full range).  Your choice.
