Why aren't subwoofer specs listed?

I've got next to nothing for a setup right now. I'm looking to buy, starting with a receiver, and will ask the topic question first before moving onto the rest. The receiver I'm leaning towards is the Onkyo 706.

I simply never see subwoofer specs mentioned when looking at a receiver. Am I missing them? I'm taking their absence to mean that it's not important what the receiver sends out because you need an amp to make it worthwhile. If that's the case, let me know. I know that's the case in cars, but don't know that it's the case here. If an amp is needed for subs and I just never saw one before, let me know.

If it's neither that I'm just missing it or that and amp is needed, please explain the other situation as I'm not even presently aware of it.

Now, for what I'm doing. I bought a $250 HTIB a few years back for an apartment and hated it. With all the research I've done recently, duh. I've since moved into a house with wired surround and will just deal with whatever wires they installed behind the walls/ceiling. The components I CAN control are the receiver, speakers, and wiring between the receiver and the sub(s) and hub.

The first part I'm looking for is the receiver as I can test it's workability and functions with the leftover speakers for the time being. Even though my setup is for 5.x, I'm wanting to be future-proof. I've done a day's worth of reading so far today and had done more a few months back, settling on Onkyo. If there's something that'd be good to know about this unit, specifically drawbacks, please specify. Thanks for your help.

Standalone receivers (as opposed to ones in HTiB systems) practically never have power for the sub, because the assumption is that you will get a powered sub.  Because of this you hardly ever see passive subs sold standalone either; subwoofers you see on the market nearly all have their own built-in amp.  Or they come packaged with an amp for installation in a rack, for some of the higher-end ones.

The Onkyo is a very nice receiver.  I have the 705 (last year's model) and I'm very happy.

Most subs have their own amps built in.  All the receiver does is send a signal.  Since the sub generally need way more power than the other speakers, it makes more sense to do it this way.

For subs that do not have amps (passive subs), you supply your own external.  These are becoming very rare.

That's where my confusion came from. With the 'thing' I bought, the sub signal was sent over speaker wire, just like the rest of them. When looking at the back ends of the different receivers now, I don't see a terminal pair for subs, so the difference is why I couldn't tell what's going on.

So, as long as the speaker set I buy contains a powered sub with a connection identical to the back of this unit, golden.

Newegg's got a sale at $550 going until tomorrow. Will I be happy? Is there something I should know? It's a TXSR706B - B just mean later/upgraded model?

B means Black.  The other one is Silver. $550 is a great price.

Yes, most any modern sub will work.  Just make sure it is powered.  Be sure to check in here before you buy - there are a lot of great internet direct companies that are great values.
