Performance Teknique ICBM-5712DX

I would recommend these subs for somebody who would like to wake up his/her neighbors! These subs pound and shake the car! I cannot even listen to them at the highest volume for more than 2 minutes cuz my ears start to hurt. THAT IS A GOOD THING! The cone is deeper than the pictures show. It sinks in about 3.5 inches, meaning that The cone has a really good surface area! The aluminum cone also gives tighter bass, and moves air harder, thus giving a louder sound. I replaced two subs of the same wattage with these puppies, and let me tell you, THESE SUBS ARE TWICE AS LOUD. The magnets in these bad boys are huge! These subs are heavy, so if you are going to order two of these, you are going to need to use a dolly to bring them to your car. The rubber surrounds on these subs are amazingly durable. Seriously, this is the fifth pair of subs I have bought in the past six months, so let me tell you, these subs are the final subs i'll buy because THEY ARE THE BEST SUBS I HAVE EVER BOUGHT!!! BUY THESE SUBS! YOU WILL NOT BE DISAPPOINTED!

These subs are awesome.
I have a good amount of money and can afford almost any sub but I am going with 4 of these.
I've used them since they were released in early 2000.

Incredible price and durability.

Hook them up correctly and give them 300-500W RMS each and you will be set.

I plan 4 with a 1ohm stable mono block class D at about 1200-1400W RMS divided by all 4.

Ive had a pair of these subs about a year ago. No lie they sound very clean and crisp at lower volumes but my short time of having them about 6 months ive blown out 2. The first time i was at the carwash playing young jeezy at about volume 7 on my alpine deck. Next thing u know i hear a loud buzzing noise from the woofers. I then noticed there was a big dent on the face of one of the subs the shape of the voice coils. The last time was the same thing but no dent. The whole time i was using a yzen 400 amp to power them which only peaked 800 watts. Now I have 2 12inch alpine type R subs and a planet audio tq1201 amp and never had problems since. My lesson learned if u not trying to experiment new brands then always go with what u know

this subwoofer is great, this is my 2nd sub and i love it. im getting tired of it and want more bass because im only hitting 400wrms. but this is a great beginners sub . in a couple of months or so i will be getting a pioneer premier 1000w rms. along with a power acoutik bamf. sonic electronix does not let me down and its great

Overall, these subs are AWESOME. They are very cheap for what you get, and seem to be of very high quality. I bought four of them for a friends jeep, and we are running it off a power acoustik bamf 4000 1D at 2 ohms, with a 2 farad capacitor and a 1/0 gauge dual amp kit. It POUNDS. We haven't turned everything right up yet until its kind of broken in, but its hard to handle they hit so hard. The looks of these subs are also quite stunning. I would recommend these to ANYONE who wants some good sounding, deep hitting bass in their ride.
