Its RE .SX. RE is short for Resonant Engineering and .Sx is one of their sub lines. The company gets a bunch of good reviews around this forum, and around some other places. You can check out www.realmofexcursion.com of some hardcore videos of some of their subs . I personally like the sx over type r. RE has laso otehr lines, like .Re, .Se. .Sx .XXX and .Mt with MT being a pure SPL sub and XXX a 1600W SQL sub. Sx's stats are as follows: SX10- $239 SX12- $249 SX15- $269 SX18- $309 Prices are before shipping. SX - 1000wRMS -- DVC 2 ohm The rest of the specs can be found on www.reaudio.com
Hope this helps a little. Check out around the forum, its not hard at all to find stuff on RE
Read the specs bro, I dont ahve the specs for the alpine type R, but for the .Sx 12 there are as follows: s: 30.6 Qms: 4.4 Qes: .32 Qts: .30 Mms: 183 Vas: 47.6 Spl: 88.1 Sd: 480 Cut diam: 11.125" Mount Depth: 6.875" Displ: .16 cuft
I would personalyl get the SX, good company, good name, good products, hit hard and sound great! ! ! Alpine is more of a CC and BB brand, go to any Best Buy and see the first sub they will try to sell you
I dont know lol Type-R is prolly a little cheaper, all I can think of. There is something that was going around here that said that the type-R out-pounded the SX but I dont knwo how true that is. Right after that post somethign else came up where the guy said that he ws deliverign un-even power in different enclosures and stuff. Anyway, I perosnally liek the SX better, but its all up to you. Read more on this forum, you can always learn new things.
The only real way for YOU to decide is to go and listen to both subs and see which one you like most.
