Gravenstein MK1, Tweeter, Woofer, Crossover

            Desperately in need of an audio upgrade at my home office. I had been using KRK Rokit 8 G2s for a number of years, but wasn't impressed with their sound. When I did sell them, I ended up with an entry level set of ADAM audio speakers, but was even less happy with how jarring the treble reproduction was, even dialed back fully using the speakers built-in tone controls. Sent them back, and pulled an old set of DIY Tritrix MT bookshelf speakers I'd build a few years back for another project. Problem, mostly solved, but the speakers have small 5 inch drivers and really can't be considered truly full range even after EQ'ing. 

So back to the drawing board, and instead of going with a known kit I selected two somewhat (ha!) compatible drivers and put the gears into motion. With the help of a great friend, we designed a crossover and now I've mostly got them laid out and will be soldering them together before the end of the week. 

The enclosures are designed and at this point I just need to commit on the wood types and it's off to the races. I'm nearly certain I'll need to adjust the tweeter padding, but I won't be able to do any further tweaking until I hear them in their LARGE ported boxes. They'll be approximately 19.5" / 49.5 cm tall , 12" / 30.5 cm wide and 14" / 35.5 cm deep. Big assed desk speakers. Still need to work out how to decouple them from my desk. Guessing foam, but TBD. 

The idea is that these will be completely full range, pretty flat down to 50 hz with just a -6 db roll off at 30 hz. I just hope I'm not asking too much out of either driver, but not knowing and finding out later how it all works is just part of what makes this fun.
