[QUOTE="Art Welter, post: 80635, member: 52"] re: Listening Get Together Leland, The old adage "take time out to sharpen the saw" applies to what you are attempting to do. Your time is valuable, yet much of it is wasted when your empirical work is not properly analyzed due to lacking a dual FFT program like Smaart that can show you FR and phase response in far more detail than the software you are using. Same applies to modeling software, you evidently are not using Akabak, (or Hornresp) which can create simulations very close to the actual cabinet response even with very complicated designs. They won't be perfect, but after a few design /build /test cycles you will see where the imperfections lie, each iteration can become closer to the prediction. In the phase of development you are at presently, using a third party for testing could be useful, but I'd suggest that learning how to test your cabinets would serve you better, as you will be able to correct, or scrap designs without having to pay additional costs in time and shipping for each iteration. I know for fact I would easily have saved hundreds of hours of design/build/test time if I would have started using Smaart and Hornresp years before I did. At any rate, doing what you are attempting without the right tools is a slow process- I have built entire PA's with a just circular saw, drill and jig saw, but it is a lot easier and faster when you also have a table saw and routers.
