Alpine Type R or S, or something else???

Hi

I have new vehicle and that means new system, i want a SQ system, I'm planning on installing a 15" in a 2.0-2.5 cu.ft sealed box and i have a JBL ms-5001 that have 500W (sonix electronic say it produce 692W@2ohm), maybe i can upgrade the amp later, but that is not priority specially if i like how everything goes.

I think Type S fits the bill nicely, but Type R is in budget reach, i don't want to spend more than $200 on this.

Front stage will be JBL MS-62C hooked to JBL-MS1004, I'll probably run then active.

With $200 budget, 500W and 2.0 cu.ft sealed box, Should i go with Alpine S or R, or should i get something else??
