Getting close to wrapping these up, a few details left to take care of. Will be taking another stab at the crossovers this week in hopes of reducing the part count from my first set. As soon as I finalize the crossovers, I’ll post the crossover schematics.
Figured the name was suitable since this set of 2.1 desktops consist of all Dayton products, including the amplifier. Everything is meant to work together in harmony and the amplifier’s adjustable crossover frequency for the sub and adjustable sub level makes this possible. There’s also a tone control on the amp and I’ll be setting the crossover up to work with the tone control in its middle position. This will allow the end user to tailor the highs to his or her own liking. If you would like it brighter, turn up the tone control, if it’s a bit too hot for you, turn down the tone control.
Now before anyone jumps in and comments “Comb-Filter Nightmare”, let me reveal the true nature of the beast. Drivers for the two cabinets consist of four ND90-8’s, four ND90 Passive Radiators and two ND25FA-4’s. Per cabinet, the top ND90-8 serves as a mid in its own sealed chamber. It’s then followed by the tweeter. Below the tweeter are two passive radiators which help tune the bottom ND90-8 that operates as the subwoofer. The bottom woofer of each cabinet is then wired to the .1 portion of the amplifier in parallel presenting a 4ohm load to the sub portion of the amplifier. Hope this helped to clarify the set up.
Confession: I’ve done a horrific job of documenting this build from a picture standpoint. When I first started the project, was just curious if the build would even be worthy of sharing, wasn’t sure how it would turn out from a sound standpoint. After cutting a quick set of prototypes and working up the crossovers, I really liked what I heard and decided to go ahead and cover them in the veneer. Perhaps I’ll cut another set of cabinets in the near future to do a better job of documenting the entire build.
The veneer is Bocote and it was purchased from Certainly Woods in New York. After receiving it and giving it a good look over, I decided to book-match it for all sides of the cabinets. This definitely adds some time to the overall job, but the end results are usually more striking, especially in a highly figured veneer like this one.
I’ll end this first post with some pictures of the cabinets. They were taken late last night right after installing the drivers. Once I’ve finished the crossovers, I’ll take some more pictures of these on my actual desk. You may notice the amplifier case looks a little lighter in hue, it still has another round of lacquer to go before being finished, and I’ll also be painting the inside of it black.
Thanks for checking them out guys!
