Great Mid-Priced Subwoofer

JohnyC, Crutchfield
14 January 2014
  • Summary: Had this sub powered by a Kenwood KAC-7202 until it was stolen, it was the best system I had of many. At the time I bought it because it was on sale and was tired of the big box store cheapo specials and remembered my friend having a 10w0 back high school that was really good. Please note, I had this set up only a few months before someone broke into my car and stole it so I did not rate build quality.
  • Pros: smooth design, clear musical tones, strong bass
  • Cons: at the high end for a budget oriented system, but you may only need one subwoofer.

Unbelievable SPL and SQ!

  • Summary: I am running two of these 4 ohm subs with a JL Audio XD 600/1 amp. I started with just one of these subs but upgraded to two very shortly after to get it a little louder and it made a HUGE difference. This is without a doubt the best setup I have ever had in my car. I have been through many different brands of amps and subs and JL Audio is top notch! They may not look like much but they hit HARD and extremely CLEAN!
  • Pros: SPL and SQ
  • Cons: Pricey but still worth it.

Buy! but, please read before buying

  • Summary: I read through some of these reviews and some people weren't getting good results . You have to match everything for them to sound excellent! Are u using a proper box and amp? These substances are tremendous. I was disappointed too when I first got them. I went through about 3 boxes. The bass waves were being cancelled by each other when I'd turn it up. Ihad a custom box made and it made these subs come alive!
  • Pros: Great quality sound. With the right set up they get pretty low. They do hit hard
  • Cons: I would like them to hit lower but it's not the subs fault because they're not rated below 22 Hz so it's really not a con per se

Overall Experience

  • Summary: If you want clean deep bass, get one of these in a sealed box. If you want it to be loud, add another in a a sealed box. The biggest mistake I see is under powering subs by people thinking there amp is pushing out 1200 watts. But if your sub/speaker is 4 ohm, you are looking at a few hundred watts rms from the amp, not the max 1200W. If your going to run these subs you must have a proper higher end amp to run one.
  • Pros: Response time for hitting each note. Sound Quality. Deep smooth ever lasting bass. Clean and clear. Bends well with mids and highs so you can't tell the bass is coming from a certain location. Not over powering but enough to give you deep rich quality low notes.
  • Cons: You get what you pay for and this will help you achieve the near pure sound as it should be heard.

Submania

  • Summary: The best quality sub I have heard in an automobile. I installed double 12 alpines in my cousins car and it rocked. I installed this sub in my sons hummer in a single box. It blows away the double alpine in sound quality. Yes it rattles your seat and you can feel it in the back of you neck, but the big difference is in the smooth transition between every bass note and sound. I have two def tech subs in my house. This sounds better than those.
  • Pros: High wattage capacity Quality is excellent True frequency response without distortion
  • Cons: none

Superb

  • Summary: I bought one of these as an open box item. Anyone who says the sound quality of this sub is less than outstanding is using it wrong, it's that simple. I have one sub in a 1.25 cubic foot sealed box, in the trunk of a sedan, firing through the cargo opening between the rear seats, crossed over at 22hz to 64hz with 24db slopes, powered with an Alpine 300W M500 mono amp. Front stage is a DLS Gothia 6.3, 45hz and up powered by two Alpine F300's. Processing is an Alpine H800.
  • Pros: looks awesome. sound is super tight.
  • Cons: give it a week to break in. after a week it sounded way tighter.

  • Summary: These subs slam! I bought two of these in a ported box running at 675 watts rms at being powered by an infinity reference series amplifier.
  • Pros: These sound great with any music at the proper tuning my rear window flexes Cant turn them up all the way they are to loud for me! They provide the extra punch to rock songs and rap it makes my trunk bounce
