10" 1200W TREIS 300 Series Subwoofer 4 Ohm 2"Voice Coils TSW310

I was originally thinking of getting pioneer 12 inch shallow mounts had them before great sound in a small space but seen these alphasonik 10's similar cone design but better spider and venting and cooler look but also same wattage handling as the pioneer 12's but 10's so smaller box needed under my back seat. They do only have 2 inch coil instead of 3 inch like pioneer but means for faster response in rock type music. For a shallow mounts nice hard snappy bass good sound tone and quality. Alittle lacking on the lows but if they were in a ported box and a touch more cuft box I'm sure they would be even better in that aspect. Definitely worth it if tight on space and want punchy bass and good sound quality.
