Great value for the money, awesome quality!
I bought both the W8K9D4 and W65K9D2 speakers, can't say enough about the quality and sound. They hit hard, look good and sound great. Basket construction is super strong to support the magnet weight. Highly recommend as replacements or for your next system build.

Great subs for the price
The sound quality for these to be 8 inch subs were very shocking. They were better than I was expecting. Will be getting more to add to the two that I have.

Awesome Subs
The Rockville subwoofers are my pick for sound and power handling. My X8 keep popping tinsel leads. But still great X8 sub repairing it for a final third time. Went with the K9-8 to see if I can poke fun at my X8 history ....lol. The two 10 inch I picked up in February 2019. The 8 inch I bought in October 2019. The bottom two are nice for heavy excursion purposes only. Not bad for the price that I purchased them for. However, I had to repair one of the coils that was bad myself because I believe it had bottomed out. I believe that it was never correctly aligned from the manufacturer. But, it has been hanging hard now for over a year since I repaired it. So much so that it's twin coil is weaker and it sucks in on high pressures. Already purchased the materials and just have to tear it down and rebuild it. It's all being pushed by a hearty and healthy 2500 watts with no problems!!!! Hope you enjoyed my review on your subs and my pics.

Integrity proven
Was running hippo massive 8s in my F150. Regrets cause both 8s failed within months, to my surprise the Rockville 8s W8k9d4s have a very impressive bass and have handled higher volume. Definitely integrity proven, Im happy.

Durable and handling full watts well
Definitely one of the best purchases I've done. It doesn't really explain what each voice coil is capable of handling but I've had my 1000watts amp giving two of these 500w (250 on each voice coil) for a little over a year and zero issuess/distortion after all the music I've played through it.

Awesome 8" sub
Wow, this thing rocks!!!!! Pushing with a Rockford Prime 500 and couldnt be happier. Cannot believe the bass coming out of this little 8" sub, i built the ported box and it was just too much bass so i plugged the port and it is so deep and crisp and clear, i love it. Specs say to cut the hole 7.76, DO NOT!!!!! Its more like 7.26 if you want to build before you get it.
