Default best 15" or 18" Driver?

I've been looking at the TC Sounds, but see they are no longer selling there full range.

I'm looking for a 12" or larger driver to go down below 20hz -3db.

Hi,
Fs<40Hz.
Loud requires large Xmax and large cone area.
Q is selected to suit your box/no box style.

Remember that small size/high efficiency/low bass cannot ALL be got from one speaker.
You must choose your prioity, one of which is low bass. Now choose which of the other two is more important.
If you go small size you will need lots of power and a driver that can handle that power. This will also require some EQ, so more electronics skills are required.
If you go for high efficiency, you will need to build it big and choose the driver to match those specification criteria.

Yep, a very nice driver.
I'll add the 15" 2235 to the list.

Depends how much you want. I have very good experiences with the 2235. 160L BR shelf alignment, sound terrific no less. Ok these are oldies but still fantastic drivers, both of them.

They're a bit rare and expensive here, so I've gone down another path. Soon I'll be using 4 Beyma 18's.

Eminence Magnum series. They have the 15HO, 15LF, 18HO, 18LF. Excellent low distortion drivers with high power handling.

Hi triode 4,

The Aurasound 1808 and the successor NRT 18-8 looks very fine.
Neo, underhung VC, large x-max, good sensitivity and overall good parameters.
I understand that you are satisfied. I'd gladly take a couple of them.
