One note about pro versions: these use raw MDF painted with a coat of inexpensive black splatter paint. It is irregular paint and is NOT acceptable for a home loudspeaker product. It is perfect for pro where the speakers are in a dark studio room, frequently moved from studio to studio, often scratched during the moving process and never studied for appearance. I’ve had consumer hi fi customer buy the pro versions before and return them when they actually see them.. It easily scratches and hard to repair.
The veneer versions in hi fi are a hand done veneer, inside and out (for pressure balance) and are book matched left to right. This is the part of England of exotic car dashboard manufacturing and the woodwork is top quality. ATC also does high gloss finish over the veneers as an option on 20s on up. The goal with our home product is a lifetime of furnture grade speakers.
The pro client does not want to pay extra for a fancy finish that will get damaged anyway.. The cosnumer client wants them to be at least a nice finish even if its black. We do have a satin black finish in our hi fi line but this is mutiple coats of paint and sanding etc..
