  3. Thank you guy's for the awesome inputs, my apologies for the late reply. Much appreciated for side by side comparison of the ipal and nsw Ricci. Although the NSW offers the best bang for the buck, I might try an external series ipal setup, albeit with some thick ass wires. 6 is kinda pushing it for that amp, even with the 152s...specially if I want the damping factor to remain high Been keeping this box on the dl but it's basically similar to the th18 but slightly modified for 21'' woofers, code named the hornicator, I haven't done any measurements on it yet but it sounds hella goo

  6. Finally got time to spraypaint my one remaining SKhorn today. I used Warnex paint and an inexpensive HVLP spray gun. After to layers it lookes pretty ok I guess. Tomorrow I will turn it over and finish the cabinet. After this and finishing the build, I will also glue some acoustic foam in the back chambers, as Ricci suggested.

  7. I'll just add that subwoofer responses are mostly minimum phase (MP). What this is implies is that the magnitude frequency response (FR) essentially *determines*, the phase and group delay response. They are mathematically interchangeable. If you have a MP system and you have perfectly flat FR, then the group delay (GD) will be perfect *by definition*. Real subs always have at least a low-end roll-off somewhere, and you will usually see group delay rise and peak in the area of the roll-off transition. The most notable exceptions to "mostly minimum phase", where subs alone are concerne

  8. Finally got everything up and running. 8 pa460s (2 boxes - each has 4 pa460 in a 2x2 dual opposed sealed box). 6 HT18s sealed up front from 0-60hz. 8 PA460s sealed from 10 to 110hz 2 Nsw6021 skrams 31 to 110hz Bass uniformity across all 7 seats improved a bit. If I were starting from scratch, I'd do 16 pa460s sealed and 4 Nsw6021 skrams. Crazy how these pa460s can only be 70ish bucks shipped with bulk pricing and 15% coupon discount. Integration all done via a 10x10 minidsp.

  9. The story is not so pretty down here, im in new zealand and bee dub is in australia i believe. In nz 18mm birch is nearly 130usd per sheet and the story will be similar in ozy... economy of scale and shipping exspense, it is what it is! Hence a lot of guys down here trying for easier on the pocket options!

  10. I don't know if you saw my skram built on page 26 or so, I built 2 of them, made of popplar plywood with a carbon-epoxy layer around to make it stiffer. Then we made the front out of 25mm transparent acryl glass, just to loose the weight savings due to the 10kg (just a wild gues, I forgott the real numbers) of those fronts haha. We didn't put them on a weighting scale yet, but without the heavy front, they would be ridiculously light! So light that we will make a base filled with sand to make sure they dont move more than the drivers do. We also didn't fire them up, but that will happen s

  11. I wouldn't go for a lightweight plywood like that for a design like this. Think of the cabinet like a musical instrument, the stiffness and density of the cabinet will contribute to the sound in many ways. If the cabinet can vibrate and resonate with the driver movement it will color the sound coming from it and you may not be happy with the outcome. If you can't do baltic birch you could get away with mdf as it quite solid and dense, its pretty heavy though.

  12. G'day! First up, hello, and let me add my thanks to @Ricci for the generous provision of your plans and knowledge. I've gotten interested in live sound recently after long absence, but this time have carpentry/joinery skills in my back pocket! I can't wait to build my first Skram once the appropriate number of pennies have been saved for a driver. For @h3idrun, I know your pain as a fellow payer of the Australia Tax! I've spent quite a bit of time researching buying drivers, so for what it's worth, here are some observations that may help: - I've found TLHP in France to
