Hi!

The Promo SDX12 kit is ordered and the computer has run hot doing some Solidworks schematics but finally I can see the finished cabinets.

Let´s get to work!

It´s going to be 85liter cabinets, after installing bracing, vents and driver Solidworks calculates the internal volume left and I´m as close as possible to my targeted 75liters maybe 0.5liter less or more because all details in the driver are not removed in the basket.
Qtc: 0,530

I´m using Inuke 6000dsp to power these beasts!

Subwoofers tuned to 23hz with three 70mm ports
Port airspeed kept below 30m/s with 20hz butterworth 2nd order highpass and very safe Xmax with 800rms input. Leaves some headroom for more PEQ :T
One port sealed gives a 19Hz tune and 100dB output @16hz
Two ports sealed gives a 13hz tune no gain there because of the 20hz EQ limitation in the inuke.

I´m going to have a replaceable portplate so the subs can also run as true sealed.

Great job with the Sketchup. How long did it take to do all that? These should look pretty fantastic.

And does that generate a cut list or parts list?

Thanks! Did not count the hours but at least one very long day.

It´s done with Solidworks the program can make PDF outprints from every angel and part sadly that doesn´t help me very much because I still haft to sketch all pieces part by part and then make an assembly with them. The CNC machince is not the newest model and can only take 2D prints so I need to remove fillets as they are done afterwards and I also convert from solidworks filesystem to DWG.

I´m i little bit concerned about the SDX12 thiel parameters they don´t sum up in WinISD to match the numbers on the paper as many drivers do.

QTS and QES are not accurate I guess they are but I can´t manage to get it right.

Tough to beat pro modelling software! About a million times more powerful than Sketchup, but I'm hoping they continue to add features common to CAD systems like Solidworks or NX.

I look forward to seeing how your build progresses!

Yes I was quite shocked when they arrived at my door told the delivery guy to write a note. My first thought was that maybe the boxes got rain on them but they also traveled coast to coast and then airfreight to Danmark and truck to Sweden. The drivers looked fine so nothing to complain about.
