As there is nothing wrong with sound of the lineup. It covers all the ranges. I only have esthetic changes:

- rounding off the corners verticle corners...giving it a nice sleek look almost B&W Naulilus 'ish

- powder coat black or white alu drivers

- change the rubber color driver to white

- change of front baffle color from the rest of the faces. ie gray front baffle...the rest is warm cherrywood
