I've used only once and return to the store or the seller was very commercial, I have exchanged against the Wharfedale VS-12X a little more expensive but certainly with sound.
In summary, the XL1350, as said, it's for "j'yconnaisrien" which was my case, because initially, the speakers are very attractive to the eye but its side, treble shrill, not midrange and bass, + it will - but rather - ..
So do not fall into the trap of flashy. If it is on, but it's going next budget y'en for the price, not more.
I was amused to open the beast and am called filter professionally?? a small white plastic cube against Wharfedale in a real circuit with a coil, I think this time is the filter ...
Therefore mistrust.
