Correct. This is a 'SPL' only woofer. If people have room, they'd use an 18 for the cone area, if they don't they'd use the 10 or 12. There is not much of a market for the 15 here, as it would be halfway between a round 15 and a round 18.

No, they still make all three sizes. The only thing they've dropped is the Warhorse as of late. Well, that and large 4 channel amps.
Try a 12 X, it will well outperform that 15 L7 you have, especially on that 1500
