Any updates on this build? Seriously considering getting 6-8 of this design  built soon ready for next year. Any measurements made of the loaded box? 18sound recommends k10, what have you powered these with?

A lot of screws, I know... But I want(ed) everything to sit as flush as possible, so I don't need to fill a lot of potential gaps. 


Just....... Wow!

Wili, with that level of precision and deep rebates I don't see any reason to be afraid of air leaks. No need for additional sealing. If your cuts are spot on, dont waste time sanding, except if you are certain that there is a problem. Also you could build without screws...... Fantastic work!

The box is 98% ready. Glued & painted, but still gotta attach the rubber feet and mount the drivers. We will try and do some measurements next week and I will post some photos of the finished box. We will get some Powersoft at a later stage, we don't yet know what we will use for the time being.

Sooooo.... Finally got some measurements done. Here is the frequency response of the sub, if anyone is interested. We ran the sub with a Powersoft X4 amp and through a Biamp Nexia DSP. Measured with Behringer ECM-8000 mic on same level as and about 2 meters from sub into an Audient ID4. Still learning about delaying and phase (polarity) alignment etc. 

Unprocessed (actually forgot to take the +8dB gain away) and processed with recommended settings from the original plans:



With the kick:
