My second home speaker build. This time it's a set of bookshelf speakers using a modified cabinet from Gouketsu.
Low down on the design.
Drivers - Arvus 6.5 inch dual 2ohm mid woofer, Arvus tweeter (16ohm), will also test with an additional Arvus super mini tweeter (4ohm).
Box - 2 way bass reflex all MDF, 40mm front baffle, 25mm sides, 18mm back, 18mm horizontal brace through the middle.
Port - 2.5 inch flared at the exit
Crossover - 6db highpass (3500 htz) on the tweeter, nothing on the mid.
Front on shot with bracing visible
Bum shot with rebated port mount
My second attempt at making the tweeter mounts (came out much better)
Woofer rear (DVC 2 ohm)
First test build, note the external crossover/high pass filter (final design uses a different tweeter and the resistor is removed from the high pass filter)
Test build - in lounge
Third and final tweeter mount with final tweeter in place
Nearly final build - in test room
Final build - in lounge

Straw port tuning
A quick test with an additional super tweeter (I definetly like them, but have other plans for them)
RTA response at one meter in my small test room (no EQ applied)
All in all I'm darn happy. First test showed some big peaks at 80htz and 3khtz. Port tuning got rid of the 80 htz peak, and a tweeter swap and minor high pass filter change fixed the 3khtz peak. Now to build some matching floor standers and a sub.
