The roller application makes them look like they have a leather texture. Nice.

Read a lot of this thread. I love the simplicity of the MK3 design. Those white ones look great. Is there a consensus on how to choose a driver? I have experience with the Fostex FE103e but not any other fullrange driver. Are the Mark Audio drivers more suited to punchier music while the Fostex excel at acoustic performances? What about for movies?

Probably more well suited to 4" drivers by folks like Fostex / Mark Audio / TB/ Fountek, et al (even perhaps Lowther?) than the FE103.


"punchier" does raise the question of anticipated SPLs and if you include movies in the mix, I think you'd definitely want to use receiver / processor's bass management to XO high enough to adequately protect from LFE impacts ( circa 80-90Hz to start?)

Of the 3-4 drivers I've so far heard in the FH3, my personal favorite has been the FE126E, while the MA Alpair7 / paper coned EL70 work better for me in vented designs such as Pensils, P10microtower, or the *kens.

A gallery / poll of FH3 builds would be interesting.

Is this okay for the 1/2" insulation? Or, do the sides have to go all the way to the back? Can't really tell on the drawing.

That is fine. The purpose of this bit is to halp minimize reflections -- time smeared signal -- back thru the cone.

Thanks Dave.

I'm at the testing stage right now. So far, these sound really good, but need to do the required break in. Bass is nice

Hi guys. a lot of info on these pages. I have decided to build a pair of MK3's. has anyone used MDF all i have read is that people are using plywood of different types. Also with the driver i have a pair of Merrill DCA4 drivers from a Zigmahornet project, how would they go in the Mk3's.

I used 3/4 inch MDF and when I rap on the cabinets the sound is as dead as my granite kitchen counter tops. These were my first MDF cabs but won't be my last.

I heard two pairs at Toppsy's house and made a pair of my own, all three pairs from MDF. I agree with Poultrygeist and would add that I want to listen to the music and not the cabinet walls.
