Now... onto subs...
To the folks in The Lounge.....
Yes, I've started a few threads here, but we wish to get back to other projects, so we've recently made several purchases for the proposed A/V room -- and most of them were influenced by posts we received right here, on the AAF, so many thanks to any and all who've helped us along. Okay, now that we have our physical media players, our new B&W center, a good A/V pre-pro and, just today, our new multichannel (MC) power amp, there's only one hole that needs to be filled: a decent subwoofer. Bearing in mind that we now have seven channels of Mac amplification, it doesn't seem imperative to purchase an active subwoofer (sub). Although we only recently installed the soundbar and active subwoofer that we purchased with our LG OLED TV -- and have clearly heard the difference they both make -- we're still only looking to set up a 5.1 system, so we have two extra channels of amplification to work with. Are we correct in assuming that one of said extra channels can be designated for use with a passive sub? In general, thoughts on passive and active subs will, as ever, be greatly appreciated and read with much interest.

I am not a fan of passive subs because they need DSP in addition to amps.

Dsp?
Kal..... Please remember that we're talking 'Audio for Dummies' here. Does DSP stand for Digital Signal Processing?

It’s not one hole - it’s two, as you need TWO subs.

Now... onto subs...
Active subs make things much simpler, as Kal says because of the need for DSP. I missed the post where you identified your pre/pro, but I’m assuming it has a sub output, in which case it’s providing a processed signal to the sub. Also in a home theater setup, the bass can often require large bursts of power for those dramatic special effects, and a good powered sub will be optimized to provide those quick bursts without putting any strain on the main amp. Most of the reasonably priced subs out there are powered anyway.

One vote for active an active sub

Okay, so no need to fear the lightning when it comes to [active] subs...and, if they're easier on our Mac amps, so much the better.

Pre-Pros
Kal..... Yes, the promise has been made. Luckily, we found a mint condition example for short money. The decision about pre-pros was driving me insane, quite frankly.
