I am a professional home automation installer for a living and we installed this high end home subwoofer. Unfortunately the homeowner was elderly and did not know how to use the system so after a week or so they had us come and remove all of the equipment. This sub was used maybe 3 times over a week or so of time and then disconnected. Works and sounds amazing !!! Nice high end home stereo subwoofer with great quality sound. Comes with the power cable as well and original manual. I will also throw in a subwoofer cable so you can hook it right up without having to buy any extra cables. Cannot beat this deal as this unit is like brand new. No broken anything, dust free, dent free, scratch free. Get it before it sells fast. Also have a high end Sony reciever that was installed at the same time posted on here if you check out my other items for sale. Here are the specs below: Discover the new Kube 8 MIE with greater accuracy and dynamics. 8 inch active subwoofer Dont let its compact size fool you, the Kube 8b may not take up much space but the bass it delivers is anything but small.

This listing is for a Kef Kube 8b powered 8 300 watt subwoofer. Kef just released an updated version of this subwoofer called KEF Kube 8b-MIE, and to be clear, this is not the newer MIE version. I bought this subwoofer about 3 years ago and it has served me well. This subwoofer has never been dropped or had anything spilled on it or had anything else happen to it that could damage its functionality. I have used it several times recently so it has been tested and still works like its new. I am selling a second subwoofer just like this one for the same price if you are interested in owning 2 of them. Ill be listing some smaller 6.5 Red and Yellow Earthquake MiniMe Subwoofers soon too. Ill stop short of calling it like new or excellent, because it does have some minor scratches on the top which I have tried my best to show you through my pictures, Its performance is still like new though and still sounds excellent. Has not been abused/played at excessive potentially damaging volumes. NOTE - On this particular subwoofer I was able to polish/buff out pretty much all of the scratches/scuffs that were on the high gloss surface. Unfortunately, the KEF logo was removed when I did this. You can still see the imprint of the small logo, which kind of looks like a KEF watermark, which is actually kind of cool looking to me, but I wanted to be clear that the logo paint is no longer there. It doesnt look weird or anything, the surface just looks solid black now. As I am selling another one of these exact same subwoofers on eBay right now, if you decide to buy them both to have dual subwoofers I can buff the logo off of the other subwoofer if you want them both to match. Just let me know immediately if you want this as I do ship items out very fast. I do not have the original box, instruction manual, or any other materials that may have been included in the original packaging. You will receive the subwoofer and the power cord for the subwoofer. The subwoofer has been packaged very safely to avoid any damage during shipping. K2 in the title is just my personal coding system to help me make sure that I ship you the exact subwoofer that you see pictured. I usually ship out on the same day if you order early enough in the day. Thank you for your interest!
