So what's it about? Well I've been on a bit of a drive to use all of the components, materials and assorted crap I have lying around. By 'using' it, I mean making cool stuff, and so this project is designed to use the following flotsam:
I like the CX-120s. They're cheap, and they sound good. I like the 'point source' behaviour of coaxials and they work really well in my 3D printed pod style speakers (nicknamed 'Turbine'for somewhat obvious reasons). But they're not exactly huge, and it's fair to say that they sound a little really thin for anything beyond desktop listening. Not so great when I want to use them in my lounge...
Enter the subwoofer. I didn't put it in the system because I want bone-juddering bass or anything - I just needed to fill the hole in the coaxial's response. But then I have to push the sub up into 100hz+ territory, and it just gets weird, as the bass feels a bit seperated from the rest of the stereo image. I also don't like the look of that big black box in taking centre stage in my room.
Exit the subwoofer, enter the Re:Mix!
The idea is simply that by using ported 8" woofers to support the low end, I can give the little coaxials room to breath, get decent bass (though not as deep as the sub, which is fine) and lose the ugly box. Win/win/win.
See above. I envisage a pair of smallish floorstanders (~900mm) with nothing on the front but a slot port and the coaxial. Simple. Monolithic. The woofer will be side mounted down low, and covered with a 3D printed grill painted the same metallic silver as the rest of the cabinet. Not invisible, but subtle. Most of the enclosure volume is given to the woofer, while the CX lives in it's own 3L sub-enclosure at the top of the main box.
