  • E-Wave Mini?

    Since I am building a pair of e waves for my home theater / music. I was thinking it might be interesting to have some small ones for surround and a center maybe even a WTW for the center? I saw a 6X6 wave guide. Maybe some 5" or 6" woofers... Anyone done this? Links?

    DoubleTap is doing something along those lines with a dual Usher 8948A with waveguide-loaded RS28F.

      Whether these designs are "E-wave like" or not I couldn't say, but they do have some degree of CD and they are waveguide designs. Off the top of my head.

      There is also this guy, but one of these probably costs way more than a set of E-waves.

        With that WG, looks like 3KHz is about the lower limit for use in a CD approach.

          The 6" square is one of my favorite waveguides, but I may have had a false start with it in Spitwad (see "Flex Your PCD Mettle" thread) because I did not understand the directivity issues, which were subsequently resolved using the 8" square variant on a flush baffle. I plan to revisit in something smaller:



          Those are PE 0.38 and 0.25 cuft cab baffles. Here's the commercial version of the one on the right:




          Here's the 8" in an AR4x cab:




          I did this with the 6" as a visual joke, but it sounded mighty nice, actually:




          Nobody's worked through MTM yet, but the prospects are clear:



          There are others, also. This would make a mini-version of the Raptors, linked above:

            JBL resorts to 3-way as described in Toole Fig. 18.18 to make MTM work horizontally:

                I forget what they are, other than an impulse sale purchase here maybe 4-6 months ago....

                  Unless its a compression artifact they look like they've got a woven looking pattern on the surrounds. Theres a TB driver that looks like that, tho I forget which one it is.

                    Real world 92db, that's what they are. Unheard of in a 6.5" woofer with bass extension this low. I'm planning an MMTMM with em with an avg sens of 97 db with BSC. How do they sound if you've listened yet? I'd love to see some measurments if you've done em?

                        If anyones' interested in a Ewave mini, another forum member linked me to the QSC parts store where the XD120 waveguide AND driver are available for $29.95 each. That's less than the average retail of the horn alone. I just ordered two and don;t know the quantity available but good news travels fast so.......

                              Looks like some more info is here, but it's for the XD125. Should be pretty close though.
