With speaker auditioning out of the way I am going to talk about the construction of the M-606v2. I love taking things apart to see how they work. I dismantled one speaker as much as possible to reveal the naked truth. The best way is to remove the back plate and disconnect the woofer and tweeter wires. After removing the four hex screws securing the woofer you may have to push from the inside to pop the woofer out.

The speaker box is constructed mostly of half inch MDF panels with the front baffle using 5/8" MDF. I was disappointed by this. I was expecting at least three quarter inch for a box this size. Tapping on the side of the box revealed some resonance, although minimal. The top sounded more solid. A cross brace between the side panels would help a lot. There are wedge bracings throughout the interior. And to further combat unwanted reflections fiber batting at key locations is used.

The exterior corners are rounded over for a softer look. Thin black vinyl veneer covers the majority of the exterior. One of the things I immediately noticed was how poorly it was put on. In a few spots debris got trapped underneath creating tiny bumps on the veneer. But the worst offender would be the port hole which looks rough and unfinished. You can clearly see the raw texture of the fiber board. It is spray painted black but they should have ran the vinyl veneer all the way through the port for a cleaner look.

iKey Audio uses a shallow wave guide with the one inch soft-dome tweeter. Interestingly, the tweeter is enclosed in its own box. This is perhaps to limit the effects of the back pressure from the woofer. I have not figured out how to remove the tweeter but my guess is to pop off the wave guide first.

And below the tweeter is the illuminated ikey-Audio label which lights up red to compliment the overall theme. It is a nice touch.

Woofer dimension seems to be ambiguous from one brand to the next. There appears to be no standard in measuring driver dimensions. According to iKey Audio the M-606v2 has a 6.5 inches woofer. I don't know where they got 6.5 inches but the outer diameter of the surround is about 5.5 inches. The distance between the center of opposing hex screws is about 6.6 inches. I am adamant that drivers should be marketed based on the cone diameter as that is what makes the sound and that is what people care about.

The woofer is constructed with a stamped steel basket and magnetically shielded motor. The cone is a woven glass aramid composite. I noticed the cone on my speaker had a 1 x 0.5 inch scuff mark on the underside. The best way to describe it is as if someone took sandpaper and scuffed up the weave pattern of the cone. I hope this does not have any detrimental effect on the performance. I am trying hard to like ikey-Audio but if they keep smacking me on the face I may have to return the favor.

There is a rear vent and from the looks of it the motor uses two magnets.
