Tnx for the update guys. I have read the comments and understand now how the UM is a better sub in performance.
I don't want to bash any brand, but I must share my experience with you I have with UM subs of several sizes.
Within 6mo of purchase, I noticed the distorted sound coming from the sub/cone. After removing the driver from
the sub-enclosure, inspection showed the spider had "sagged" and was not straight anymore.
This happened with the driver facing the front of the enclosure, so it was not upright or downward.
When I contacted PE about this, I was asked to send pics, which I did, and I was offered a refund or replacement, which was top notch !
I got the refund and ordered another UM at a later time, sadly, this sub had the SAME issue, as if it was a mfg error.
While I'm not saying all the UM subs are bad, 2 out of 2 were for me.
I live in South America, so it takes quite a while for me to get my orders, but I do business with a reliable freight-forwarder,
my packaging never came damaged.
However, it did however made me think again about buying another UM. While reading the comments-section of the UM subs
on the PE site, I did notice some more buyers with the very same issue. I hope it has since been resolved.
So if the UM is better, I hope the build-quality and their parts are also...
Cheers guys !
