HT = Home Theater

Meaning for home use in a home sound system, not a car.

I would also go for 30-34hz tuning, definitely not 21..

Head over to a box calculator like RE's box calc. or the12volt's or one of the other ones and play around there.

HT = Home Theater

Generally you would tune a ported sub box alot lower in a home theater setting than in a car.
