Pros: Very nice, clean sound. Great excursion, flexible wattage handling, and just looks cool to boot.
Cons: Cheap wire terminals. (the slide/clip on variety) I use low gauge wire for my sub, it was a pain in the neck to find terminal connectors that size. Stick with the spring push terminals Infinity, you're better than that.
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. I was looking at Focal, Hertz, JL, and even the Kappas because I've read that they specialize in sound quality, but I went ahead and saved some money and tried out this Reference, and its an amazing 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
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. They make my suv shake and can make it feel like head is gonna explode.
Cons: Requiring a large box but that's to be expected from these monsters
Summary: I have a basic Toyota Rav4 2011 and upgrade the factory radio and speakers. The reciever is the JVC Kdr-520 with bluetooth adapter included, the seakers are 4 Infinity Kappas 629.62i, I let the two factory tweeters that sound good. Have all hooked to a Firefly 5 channels amp and a 7 band equalizer from BassInferno. I have a Sony sub-woofer but want to get an Infinity sub to match the voices. I am very proud with the good bass punch this sub-woofer produce.
Pros: Good punch bass, prety deep sound, very good construction and a beautiful appearance.
Cons: I only have the complaint that Harman Kardon on this Reference Infinity Series do not use a good connection like biding spots, it use flat metal connections of the same size. I was a little dissapointmen with that and get the plugs connector to this size was a pain. But the connector get tight and you can be sure that them wil not be disconnected from the sub.
Summary: I have one of these subwoofers installed in a compact sealed box. The woofer has relatively tight bass for a 12-inch driver, and a minimal amount of boominess. In other words, I love it! The sound is really smooth and clean, and there is plenty of punch there to remind yourself that you have a subwoofer in your car.
Replaced a 25 year old Rockford sub and am very pleased
23 January 2011
Summary: Bought a Rockford 10" sub back in 1986 and it was going strong...until a BBQ propane tank in the hatch rolled over and killed it. RIP Rockford Sub. Enter the NEW sub : - ) I was looking for a 10" sub so I could use my existing box but things sure have changed since the mid 80's. What took a 1.25 cubic foot box back then now take a .6 cubic foot box. The subs that wanted that size enclosure are all 12's these days, but obviously won't fit in a 10" opening.
