With respect to the Onkyo 5509. I can concur with Bo that this is a great DSP for HT systems - it worked great in my 7.1 setup. When you have 7 speakers in one room you definitely need a clever DSP with something like Audyssey XT32 or other room EQ software. I am completely sold on that concept. The room is a huge problem and getting a balanced totally clear clean sound is a huge challenge with so many speakers creating LF modes and reflections everywhere. The 5509 with the calibration microphone fixes everything in less than 20 minutes - brilliant.

That said, I prefer two channel music listening without any DSP at all. Although the Audyssey XT32 room correction sounds very good - to me pure two channel still has the edge but it might be just my room (in another less favourable room perhaps DSP two channel might have the edge)

Many Full Range capable speakers are set up in rooms that do not support 20 hz. Meaning...... they can’t hit the notes or the notes are way too low in DB for the room. This could be for a number of reasons; the room space itself, and/or the constraints in how the owner is allowed to place the speakers in the room; the amp, etc...

The speaker manufacturers know this. It’s a very old story. They have a choice to make. They can EQ their main full range model, with woofers to handle EQ; or they can leave well enough alone, and bring out a new speaker - the subwoofer - to add to the bottom line both financially, and music wise. The subwoofers provide the additional benefits of allowing optional placements to fit bass into the room better with the main speakers.

.... unless you’re Bo1972, whose business model we have seen, is to place the subwoofer beside the main full range speaker butted up against the wall. Then EQ the hell out of it. And hey ...why not.... For the average person whose gear - no matter what gear - needs to placed along the front wall, this business model works out.

But put that same person in a room where the speakers are placed, and amp’ed as designed; and that person, depending on how audio crazed he/she is after hearing; will be looking for a new place and/or spouse.
How far do you want audiophilia nervosa to take you?

"With small 8" woofers obviously you need a subwoofer."

I guess Jim Thiel (RIP) did not get that memo. The CS5 he designed used 8" woofers and measured flat at 30Hz, -3db at 25Hz, and -5db at 20Hz.

With small 8" woofers obviously you need a subwoofer.

Not necessarily. The Infinity RS1-B speaker system used 8-inch woofers, and it surely didn't need a subwoofer. To be fair, it did use six of them per side.

I didn’t mean say you can’t use 8 inch woofers - just that they are inadequate to properly do the highest end true full range. I guess I should have added - at realistic volume levels! Of course the limited excursion of 8 inch can be used down to 20Hz but you won’t get much useful SPL out of it....as it needs to move linearly for several inches to have any meaningful output.

Agreed that 8 of 8 inch woofers is probably equivalent 2 x 15 in area but still won't be as good at powe handling or large excursions (won't get as high SPL)
