Okay guys this is my opinion of the x500 with a few pictures added, first off i have to commend cambridge audio on making a seriously powerful subwoofer the x500 sits at the top of the minx range as there flagship and i truly believe it when they say it's 500watts.
I thought i would future proof myself and get the x500, but boy this thing is a monster... when i took it out of the box the first thing that hits you is the quality the weight and also the compact dimensions.
Once i hooked up the speakers and sub i ran the audyssey on the denon, i followed the instructions on the back of the sub by twisting the crossover frequency knob to 120hz which has a min20 icon, after the calibration was finished i checked the crossover settings for the speakers on the amp which was set to 200hz,
I then started to play a few tracks and my word the min20 speakers sounded beautiful, so clear and precise the sound of instruments and vocals were so rich, but the bass from the x500 is enormous and very, very deep!!! I mean this thing hits hard i was getting waves of clean punchy undistorted bass which was effortless in it's delivery.
The downside of this though was that it was and is definately to much for my little flat it got to the point of vibrating everything in my room and was bordering on major overkill it was good but also scary lol...
Today i had to take it back and exchange it for the x300 which i'm pleased to say was a good decision it loses a couple of hundred watts but it also sounds similar to it's bigger brother and kicks like a mule.
For anybody who craves deep powerful bass and has a large room i would definately recommend the x500, for me though i don't feel short changed with going back to the x300 as it sounds incredible for it's dinky size providing a very deep bass but to a more managable level for my flat and for my neighbors.
Heres some pictures of this beast, my camera skills aren't the best and for some reason i can't upload the picture i took showing the forward facing bass driver and passive radiator but enjoy.
