Pretty Good - Run them at 200 rms and they are fine.

The following review is for HFi12D4, which is a part of the bundle you are viewing.

I purchased one of these speakers at a liquidation, which cost me more.
I built my own box to my specs because i like bass around 20 to 35 hertz.
My box is 3.92 cubic ft with a 4 inch port, tuned it to 25 hertz. with this speaker it really pounds some those low low bass songs.

Songs used: "I'm Goin In" - Lil Wayne, "6 Foot 7 Foot" - Lil Wayne
"It's Goin Down" - Yung Joc "Blueberry Yum Yum(Chopped and Screwed) - Ludacris". Some songs from Birdman, of course "Late Night Tip" - 3 6 Mafia. "Oxycotton(Chopped and Screwed)" - Lil Wyte
"In Da Club " - 50 Cent. "Hypnotize & White Girl" - Young Jeezy

These are just a few I could remember

Great Value

The following review is for HFi12D4, which is a part of the bundle you are viewing.

I own 2 of these, with a sony 1600 watt mono amp. They are a great buy for anybody wanting good sound with a low budget.

Best cheap sub i found for the cash

The following review is for HFi12D4, which is a part of the bundle you are viewing.

I had doubt`s about a sub this cheap. I bought 4 of them and put them in a ported box and all i can say is wow they sound awesome for the price and get pretty loud but they do have limits. I have them hooked to a hifonics brutus bxi1610d in a 2 Ohm load and if turned up to loud you can smell them but for the price there not bad but if you want ground pounding bass look to other subs but if your on a budget & just looking for something to get by with there worth the cash....

eh not to good :/

The following review is for HFi12D4, which is a part of the bundle you are viewing.

i hooked 2 of these up and ran them at 300 watts rms each and the second day of playing them they started to bottom out on a few songs and they almost blew :/ but on low volume these really compliment the music but if your looking for low and loud bass these wont do the job as well as others

Best Bang For Your Buck!!

The following review is for HFi12D4, which is a part of the bundle you are viewing.

For the price, I dont feel you can beat this speaker.
It is crisp, clear, and best of all, HITS HARD IN A PORTED BOX.
I built the box to Hifonics specs with the proper volume and port size, and I am very happy with its performance. I have delt with many high end, high dollar woofers and Im just amazed at this little cheap guy.
I am giving it roughly 600watts RMS and 1000Watts peak with no distortion, just clean hard bass. I was unsure about giving it this much power, but it handles it very well. Its all about the box and amp. Dont skimp on a box, get the proper volume and port size and this sub will impress you. Bass, I love You plays amazing and this woofer can MOVE SOME AIR. Thats all I have to say.

This is a great deal for the price I got two hooked up to a 800 watt kenwood amp giving 230 rms to each sub and its beating up my trunk like you wouldnt believe people even been askin me if they were two 15"s!! I think there loud and meet most peoples expectations, imo great buy you wont be disappointed..planning on buying two more in the future and a bigger amp but for now im defenetly loud with these

I love em

The following review is for HFi12D4, which is a part of the bundle you are viewing.

These subs far exceeded my expectations for how much I paid for them. I have these in a fat ported box in my Civic with a Boss GT1500D. All it does is rattle everything and make everyone laugh. Unfortunately, the frequency response isn't quite up there with Kicker or other top brands. They quiver a bit in hi-bass, the mid-bass in these are great, but they kinda bottom out when it comes to low-bass. Surely, they earthquake on low-bass but its just not quite up there with other subs. But all in all, they are still a definite GO for how much they cost. So buy em =]
