  • Re: Flex Your PCD Mettle:

    Maybe this is a better place to post this project and question. I have been thinking about eWaving my Best Buy Insignias. First thought about using the 6x6" JBL WG but it was just a tad to big. I could make it fit, but it would take a lot of trimming. Then I saw Zilch's project using the Selenium HM17-25 and that WG would not need trimming to fit.

    So below is a pix of the Insignia and an FR for the woofer only.

    How do all think this would work out sound wise? I know I can build it, but would like to get some opinions as to the match up between the woof and WG.

      I can't quite fit pairs of 226J in the Dayton MTM-0.75 along with the 6" square waveguide but the K6.5 buyouts squeeze in nicely. Thus, for S-6.5 I've ordered up a pair of these squircle B&Cs:

      I want to make FAT™ happen here, now that PCD has shown how.

      Those'll also fit with the 6" waveguide in TW-0.38 for a truly diminutive (Indignia-size) package....

        You're just going to have to try it, Dennis.

        Since you use those nearfield, I don't think there's any detriment to the narrower dispersion of the little Selenium waveguide in your application.

        Shop around a bit further, and you'll find it just under $100 street price.

        Soon as you move up from D220Ti, in neodymium, especially, you get to this level pretty quickly....

          The spec'ed response of the B&C 6NDL44 shows really good extension and to my untrained eye, minimal breakup. The bottom end response looks ideal for a 2.5 way, though the spec sheet doesn't say anything about the test box.

          The basket looks really strong. Now I want those...LOL.

            FAT™ coaxes an additional 2.5 dB out of them, which may get this combo to 94 dB.

            I don't see any issues, either, thus far; if K6.5 works, these will too.

              Thanks Z. They might be my main speakers in a couple months. No work for 8 months now and just signed the house back over to the back. We have 6 months to get out. If we end up in an apartment, they will be it.

              Would you recomment just using the crossover you posted for that WG?

              Edit: is there a better WG that you would recommend for that space? I have 7" x 5.25" to work with with no trimming.

                  When I typed in "FATTM" into google, I got Al Yankavitch. What is FAT?

                          OH, MAN! The big boys with custom drivers in their arsenal certainly know how to make this happen. I put Celestion CDX1-1731 on the little 6" square waveguide, dialed the L-pad flat within +/- 2.5 dB, and now can't wait to get this little guy into PCD and optimized....

                          Zilch, what 8" driver are you using here with the JBL 6" WG and Celestion CD? And, did you rebate those drivers or have it done? Those look great. If they perform well, I'm in.

                            That's a 6.5" woofer, actually (the cab is just 8.5" wide), JBL 226J, available through your JBL Pro dealer or authorized JBL Service Center. $80 MSRP.

                            I have a woodworking pal with a complete shop who's helping me with the baffles. I give him blank baffles (spares are available for all of the Dayton cabs,) driver and waveguide, and a layout, and he comes back with milled baffles ready to load.

                            As I demonstrated in the Mini E-Wave thread, mounting flush matters....

                                Sure looks sexy. What's the response look like at the lower end of the spectrum?
