DK Design Group X-Dream - wow

We can debate the veracity of some claims made for DK stuff, but one claim, that it takes three months to machine one enclosure, is absurd. An automated machining facility such as the reviewer cites, ought to be able to knock off several per day, with most of the time taken up by manual setup. If it really took 6 months/pair they would cost a lot more than $25,000.

Marakanetz...Actually, marble isn't good...it rings. It looks nice. A layered construction, for example using styrofoam and sheetrock, is pretty good. There is also a material, the name of which escapes me, which is like styrofoam but with the plastic replaced by metal. This stuff is quite light, can be machined, and is very rigid. But the best way to stiffen any structure, including loudspeaker enclosures, is to curve the walls. Sonotube (used in building construction to pour concrete) is good, even though it is made of cardboard. But, who would pay 25 grand for a cardboard loudspeaker?

Guidocorona...Excellent idea to use Pumice. Similar to my suggestion for the foamed metalic material, but a lot less expensive.

Lrsky...Seriously, if it really takes three months to machine your chunk of aluminum you are not doing it right. Although you may not see a need to lower the price of your product, think of what it would do for your profit margin if you could crank out several per day!

Lrsky...OK, that makes sense. Previous comments suggested that cutting the metal for each speaker took 3 months, which, to anyone familiar with CNC, was obviously wrong. Thanks for clearing it up.
