The martycube has a 20hz tune and its smaller then your design . Your vertical bracing has one extra piece needed.

I have a SI18D2 that's going to be powered by a inuke 1000DSP in bridged mode. I'm having trouble calculating port length for a 20hz tune. I've come up with 3 slot ports that are 32.75" deep x 7" wide x 3" high. The bracing and driver displace .907 ft^3. I'm not sure what to do from here, or how to calculate port length? can anyone offer some suggestions? Thanks for looking.

Thought i would update this with some pics of the completed build. It sounds great, but its really not enough bass for my very large open room. So i'm considering selling it along with the inuke 1000dsp and building two smaller 18's powered by an inuke 6000dsp. My question is does diy audio have a market and how much could i sell this for?

How big is your space? Why joy just build another one if those?

That looks awesome. What material did you use to build it. It looks like solid wood or is it plywood with veneer? Love the dark color, what color stain is it?

Where is your "gap" in terms of bass? Is it below 50 Hz or higher? You aren't going to gain much by putting in two 18's with smaller enclosure if aiming below. Remember that "hoffman's iron law" is pretty much in play here. To put this in perspective...NOTNYT is pretty much the poster child example of the trade between ported/sealed for the lower content.

Price? You'ld be fortunate to get back what you have in it. It's huge, heavy and you'ld have to explain to anyone interested what it is and how to use the amp. Not sure many folks trust something "Homemade".
