Incorporating Sub into two channel stereo

Rel subs, and I assume other can hook up directly to your power amp. Small gauge wires that do not make hooking up the speaker wires to your B&W's a problem. I have always thought this was the best way to hook up a sub. I am sure others will disagree.

Good luck

i can't believe they would not put you a sub out on that equipment, but krell is not about sub woofers, with the 804s i don't know why, but we all have out listening needs and sometimes want to explore, as i have many times, so in saying that , use the record out and use a bw sub to try and match crossover...if your speaker goes down to 40 , then put the crossover on the sub at 40...hope this helps...record out should give you an output to the amplified subwoofer

The record out is fixed level and will be a royal PITA to set the sub level manually for each listening session. Any sub that has a high level (speaker) input will work.

If you use the balanced outputs from the preamp into the amp you can use the unbalanced preamp outputs into the sub. Some prefer using speaker connections and others prefer preamp connections. If you have the option, you should try both to see which works best for you.
