***EDIT***
Here is the final product! Ended up with MTM config, 1250hz crossover 12db/oct.
-------------Thread Start-------------
Hey Guys,
Well my front sound stage build is all done and wrapped now... Been listening to them for the past month or so in bliss. Everything sounds great... Except they make my non pro-audio rear speakers sound like crap.
SO, in the interest of timberal matching, and feeding the DIY bug I am about to begin my build for the 4x rear speakers to complete the 7 channel sound bed. So I will have TPL-150H AMT Tweeters all around me.
This is also going to act not only as my rear speaker but also as a prototype build to perhaps look at selling these as a kit or offer them as finished speakers locally here in Australia. Other people would probably consider these very useful for a main sound stage. But with my mains, these should compliment very nicely.
I am going for two way. Dual 8inch Faital 8PR200 woofers, and the TPL-150H AMT.
1800hz crossover point. 8ohm nominal. 98db/Watt Sensitivity.

Here is the design I have arrived at and the dimensions. I am looking at a box which has a 3db rolloff of 50hz. Flat to 80hz.
Everything will be cut on a CNC machine. I have designed it so it should be easy to cut more and what boxes together in minimal time with good strength. 25mm MDF throughout. These ones are just going to be sprayed with Duratex but hopefully the finish and texture will come out quite nice. I really like how the baffles turned out on my L/C/R speakers with the sprayed finish.
More to come soon! I will try to document this build a little better than my last one.
