A Very Pleasant Surprise

I had been using a Martin Logan Dynamo 1000w and Sunfire HRS 12 for five or six years. Both are 12" sealed box subs with very similar physical dimensions. I decided that I wanted to upgrade my subs. I was working with four main factors. My new woofers had to be sealed box, front firing, less than 15.5" wide and $1,000/each USD or less. I also wanted to see if there was any benefits to matched vs. mismatched subs. I know who most of the players are in that range. I became intrigued by the technology in the Kube 12 MIE and I have a lot of faith in KEF engineering. So I ordered two Kube 12 MIEs.

The new KEF Kube 12 MIEs outperform my old subs in every way. They are much more detailed. They are cleaner and tighter. They certainly play deeper frequencies. Their frequency response seem much flatter than my old subs. They play frequencies that my old subs seemed to glance over.

Needless to say I am extremely pleased with the KEFs. On paper it might be easy to think that I made a lateral move and not an upgrade by going with the KEF Kubes but that is not the case. They are certainly a big upgrade from where I was. Maybe it has something to do with them being matched.

I believe the Kube 12 MIE are a better sub than the market gives them credit for and they deserve more love and respect than they get.

HIGHEST RECOMMENDATION!

What a Nice Surprise

I decided to replace my two subwoofers. They were not a matched pair (same size but different brands) and I often wondered if a matched pair of subs would provide improvements. I think I found my answer.

I had certain parameters that needed to me met. I wanted two 12" sealed box subs (I am not a fan of ported subs) that needed to be less that 15.5" wide. I was not looking for higher dBs or vibrating things in my 14ft x 22ft room. I was looking for accuracy, resolution and detail. If the went deeper in the bass that would be a plus. Of course I was trying to hit a certain budget.

I looked at all of the major brands and realized many are excellent. I decided to trust KEF technology and buy two KUBE 12 MIE subs. I could not be happier. They made all of the improvements I was hoping for. The have more output in the deepest bass than my previous subs. They are more accurate. They have flatter frequency response. They reveal more details at all volume levels. I am hearing details that my old subs glanced over. Obviously they fit my budget.

In summary, I am very pleased with my KUBE 12 MIE subs. Again, they made all of the improvements I was hoping they would. If you are shopping for sealed box subs that are great for both movie and music, the KEF KUBE MIE subs should be on your shopping list.

HIGHLY RECOMMENDED!
