The new Type-R's have an accordion style surround, so it has ridges and it's made of a newer type of material...Can't remember what it's called though, sorry.
Yea, well model number is SWR-1241 for old and SWR-1242 for new (for 12") for the lode ones they have 1000w peak and a 300w RMS. The new ones will have a 1500w peak and 500w RMS. You can get them from bestbuy but they are overpriced. You can try local stores around your area ortry online stores like sonicelectronix.com
