In my defense, a really long drive (17 hours) followed by not much sleep over the last couple of days led to this brain fart. Lesson learned, never plan your next build while in "Zombie Mode".

        I may draw it up just for giggles, I'll post it up in here if I do so you can see it.

          Funny that PE didn't have an example?

            Here ya' go. One of 12 per side arrays, the other with an array of 8" subwoofers beside it.... I had that one handy already for reasons.

            I was lazy with the box design, sue me.

              I like the industrial location with the two sprinkler risers ;)
              Expensive caps need time to break in. More expensive caps take a long time. Cheap caps sound great right out of the box.

                Cool. While reading this thread, I was thinking that PE should supply a schematic for a crossover.

                I assume, there would be one "ideal" crossover that would work with whatever enclosure people want to make (since the drivers are always going to be the same)...is that correct? Or would there be a reason for different crossovers?

                I have a pretty basic XO done for the 5", will be working on the 4" this week. We will post these schematics when I get finished. We will also include baffle dimensions and offsets. These will be good enough to sound reasonably smooth and not cause tweeter damage but I'm sure a lot of the guys here can come up with something that's more refined for a per-application basis.
                Your results may vary.

                  Haha yeah, I like to use that backdrop, beats a plain background with no floor plane.

                    Thks, is the crossover for the 4" or the 51/4" coax or both?

                        Well, punching in the driver diameter of 4.75" which would also be your tweeter center-to-center spacing yields a 2,857 Hz wavelength.

                        The response graph is up: https://www.parts-express.com/pedocs...ifications.pdf

                        ...and a 3k crossover point doesn't look impossible, especially with your DSP magic at your disposal.

                        But, it will be REALLY hard to tell if the woofs or tweeets are playing by ear if you're not sure which wires are which like Saturday night! Yes the tweeters did have excellent bass response.

                        I guess you'll have a better idea once you play with your set a bit to see if the components are worthy of such a huge time investment.

                          Yea, yea, rub it in. The wiring fiasco was pretty embarrassing. Will make sure to label the RCA's from the DSP in the future to prevent this from happening again. I'll also talk with Rick about the centers and see what he thinks. Would be pretty close to the FS of the tweeter but may not be as much of an issue since it's an array and DSP programming.

                            I like the warehouse backdrop but was thinking more along the lines of a CBT array with the subs built into the back of the enclosures. What software are you using, I assume it includes the backdrop images?

                                I use Autodesk Inventor. There are a few different backdrops available but I like that one because it gives a bit of scale to the speaker. I had already designed the 8" sub array so I just tossed it in for giggles.
