Summary: This is an exceptional value. The specs and build quality are excellent. 13mm Xmax and 90db of sensitivity make this a great choice for systems with lower power ratings. I built a sealed wedge box for this that fits behind the passenger seat of my regular cab F150 and is 1.33 cubic feet.
Pros: Outstanding sound, responds well to lower power.
Cons: Spade terminals, unable to find woofer displacement anywhere, manual unclear on box volume requirement as a result.
Summary: Sub looks awesome right out the box! Made my own enclosure according to the specs and I was surprised how hard and loud it performs. This is with all everything turned down/off; amp and receiver. Now I need to upgrade my door speaker amp to match!
Summary: I recently just got these (I traded my focal p30 because one blew in about 3 hours) but even so these compared to the focal subs is no comparison in my personal opinion. 1. The sound of the infinities is a lot louder and a deeper bass.
Pros: Sound, build quality, looks great, shakes the car :)
Summary: I have two of these in a ground shaker sq212 box powered by a kenwood kac5001ps amp and all I have to say is daaaamn. These subs hit hard II'm still breaking them in but have turned it up a lil to see what they can do and I'm impressed with what Ive got.
Cons: Requiring a large box but that's to be expected from these monsters
Summary: I have a 1999 VW Passat, which has a sizable trunk. I'm running the sub off of a Rockford Fosgate R500-1 Monoblock. I have it in a 1 cubic feet sealed box. And I must say, the sound is great for a starter sub.
Pros: Great looking, boomy bass or sound quality bass, flexible, good price, 1 cubic foot boxes are easy to find and cheap
Cons: Make sure you have the right box, a good deck to customize your music, and an amp w/ a gain and bass volume switch in order for you to tweak your sound, or else this will just sound like a regular whatever brand sub
