2 channel with sub woofer out?

There are several ways to add a subwoofer to a two-channel system.

1. Send a full-range signal to the sub and use the sub's internal high-cut controls to set the roll-over characteristic. send a full-range signal to your mains as well. This requires a pre with two main-outs per channel or using a signal splitter to get two feeds from each channel. I like to let the main speaker's low frequencies roll off naturally and add the subwoofer so it augments this natural roll-off rather than employ a bass-cut on the mains.

2. Send a full-range left-right signal to the sub and use the sub's cross-over to send the signal to your main speakers. Most subwoofers have connections for this sort of set-up. I find that this can degrade the mains signal but depending on the sub the effects can be very slight.

My own preference is for TWO subs; one for each channel rather than one mono sub getting both right and left feeds. Two smaller subwoofers can be placed in a room more conveniently for better response in terms of room interactions and more believable transient attack.

At our price point - less than $3K - you have many options so your budget shouldn't be a limiting factor.
