i asked about these subs on the forums about 3 or 4 months back and nobody knew about them. So i took a chance and bought them. Im writing this to help out anybody finding these subs and wondering if they are any good.
I bought a pair of Momentum Flash 12' 4 ohms which handle 400w rms a piece and hooked them up to my JBL 600.1. to tell you the truth they were very very loud and very clear i was very impressed at how good they sounded.
so for about 2 days i rolled around enjoying life but i started to lose that ear busting bass i felt. so i popped the trunk to find out the left one was blown. and i never turned the subs up loud nor my gains it would kill me if i did :p
Didnt have time to tell Cadence then because a icestorm hit texas and i was chilling at home but after it was over i turned up my tunes and noticed my sub had a whislte to them now. poped trunk and bam a hole in my right subwoofer cone out of nowhere....very very upset about my week's worth of speakers.
I have since sent them both back to Cadence and they are going to send me a pair of there Ultra Drive subs instead. Nobody on the boards knows too much about them either so when i get them ill let you know if they are any good and last more than a week.
In summary dont buy the Momentum Subs they sounds great but are none too durable.
thanks for readin
