I'm a huge proponent of buying the biggest woofer you can possibly afford. My theater is 1200 square feet and I have (13) 18-inch subwoofers in it. My bedroom is 16x16x12 and has (4) 15-inch subwoofers in it. Solid, tight, controlled, bass is all about moving air effectively. The more cone area and amplification you have (i.e. big power, big drivers) the less you have to increase gain. The less you have to increase gain, the less those drivers have to move for the same amount of sound. The less those drivers have to move, the more controlled those super low notes become! I have response clear down to 6Hz in my theater and it's amazingly controlled. If I had the money for 24" drivers, I'd have those instead. So yes, buy the bigger drivers because no one has ever set up a listening room or theater and said "you know, I wish my subs were smaller", LOL!

Great to hear that Chris is still part off Paul's team. Note to Paul. We need to see more of Chris.

“Two 8 inch drivers have more square footage than a single 12” This is not true! A 12 inch driver has about 10% more surface area than two eight inch drivers.

I emailed Paul years ago about adding a subwoofer to 2-channel system.

And that is why I have an 18" subwoofer.

In case this information is useful: my experience of running large PA systems (usually with 10 sub cabinets per side, for scale context) I’ve noticed I needed a mixture of sub sizes. We have subs with dual 18” drivers that have, surely, lots of low end, but because of the physical sizes of the woofers, getting them to move quickly and catch transients is difficult. So we also add in cabs that have 15” and 12” woofers. They can “kick in” faster and catch transients more quickly, so therefor give a clearer low-end representation. The higher drivers handle the 160 down to 60Hz range, the 18” drivers handle the 60Hz downward range.

Note to Chris: Please check Paul's calculations and resulting confusions before you let him turn on the camera.

This guy is cool, and not cool at the same time. Bless his heart

That 8” in a nice horn enclosure. 👍🏻

Morning Paul. Great info.

Paul seems like such a hard worker, it’s inspiring.

Hi Paul. I am glad to listen again. I've been wandering off in the land of historical sewing. I keep wondering about home construction, especially insulation and how that has impacted fashion design. I'm sure it has also impacted home acoustics over time as well.

Good quesiton and a good answer!

This was good insight. Xmaxx and power to move the mass next 😍

I guess Paul meant 2x 8" is a larger area than a single 10".

Great talks , thanks dear

Cool drivers that they use.

I have used the likes of kef and rel before. But wasn't too keen. I went for a bk electronics 12 inch woofer paired with my monitor audios for my hifi. Built by a smalll company in the uk (essex) with the optional high pass lead. Sealed design and find 12s are the perfect balance in my room. Nice tight controlled bass, not interested in extention when it comes to music. Just tight a clean.
