MKSOUND_HT Posted September 3, 2012 Posted September 3, 2012 Hey all, Well i've decided to design a box after all for my Koda Speakers which have the following speaker sizes: 2x 10" low bass drivers 6.5" Mid Range 1" Tweeter The original enclosures were quite large. But unfortunately I wouldn't be able to make any measurements from them so I may end up having to get the speakers measured out and figures would be put into the calculator. I was thinking about putting the drivers on the side of the enclosed box (each may need to be offset to make sure the magnets don't contact) and doing something fancy with the tweeter/mid range. Any suggestions/photos to inspire me would be much appreciated

Paul Spencer Posted September 4, 2012 Posted September 4, 2012 Firstly the easy part - the box. If you want to have fun with the box there are a couple of things you could do. 1. Make it slim but deep, with side firing dual opposed woofers. Great for reducing box vibrations. Make the box 210 - 280mm wide. The woofers can both go right near the ground for better coupling, but your 6" mid needs to go perhaps a little lower than with the front configuration. Floor bounce with the woofers is avoided. Or you can try various other arrangements, with different pros and cons - front and back, both on the back, each with a different room integration. 2. Drivers arranged in a clamshell isobarik bandpass as used by Jamo. You can do curved sides that way. 3. Same arrangement as now but with curved sides You have a passive crossover, right? Keep in mind that changing driver location will affect the bafflestep aspect of the crossover. Not a bad idea to bi-amp these, but you really need to measure them. Forget online calculators, especially if doing anything passive. A passive is affected by impedance and you need to measure with the drivers in their box. Even with bi-amping, you still need to measure to take account of acoustic slopes in your box, even for a simple thing like crossing a mid to the woofers. Doing it blindly is going into no man's land. There's a million ways to get it wrong and only two to get it right, if going blind - pure luck, or being not particularly fussy.
