I bought two of EV ETX-18SP and two of EV ETX-35P to build the great PA.
The subwoofers have a lot of pressure and it's very easy to use them and adjust.
There are four steerable 100mm wheels on the bottom and you can drive it easy to the stage.
Two of the wheels have a locking device, so that you can stop sub where it should stand.
The front led can be configured on / off or limit display.
It is noticeable that the peak limiter flashes relatively early ( about 120 dB already ) - but this is certainly intent.
And it's really mastered the whole range. 135 dB SPL peak is here definitely not advertising promises,
but real and measured. These are real subs IMHO 50 stars for the pair and highly recommended!
