  • FUSION-4 QUAD4 build thread

    after much back and forth on a kit to build, I'm going with the FUSION-4 QUAD4. I have built several tri trix and trust the work of Curt. I already have 3 subs, so I don't count on my mains for the low, low end. I had read that there may be a center channel design to accompany the FUSION-4 QUAD4 down the road. I will attach a rendering of what I plan on doing. I am going to add some height and have the waveguide at ear level. I have always wanted to incorporate a way to put the crossover on display,,which is what the angled board within the lower part of the enclosure is for,,probably use a Plexiglas pane on the front to prevent dust to the crossover. Anyway,,that is my basic plan as of now. Just ordered the kits from diysoundgroup. I haven't seen the crossover diagram yet, hopefully it arrives with the kit. I did read that the design shows 1/2" for the walls and 3/4" for the baffle. I would prefer using all 3/4", so I'll have to figure a slight depth adjustment to make up for the difference.

    should be pretty sexy. You will some outriggers I think.

        Good hunting! ...waiting for my two kits to arrive, need to have the baffle in-hand to finalize what I have in mind.

            Don't know, but I'm anticipating ~10-ish days based on a pair of Anarchy tapped-horn flat-packs received a couple of weeks ago.

            Which were also flawlessly done (and packed).

              Mr ejh,,could you let me know what type of documentation is included when you get your kit? Hoping to see a more detailed enclosure plan.

                  Rockiron,

                  FedEx just dropped off the box from Erich a few minutes ago; I think you're going to be very pleased (I was, anyway!) with the packing, and the quality of the CNC work on the baffle.

                  The crossover design is proprietary IP, so let's respect that here.

                  Didn't get anything on the enclosure internals (bracing, stuffing, et cetera) included in the package, so I've dropped a quick note to Erich (and a PM to Curt) asking for a bit of guidance... and I'm sure they'll bail me out, well before I actually need it ;)

                  So far, color me intrigued and very optimistic.

                  Ed

                    sweet, thanks for the update. Stuffing and internals is what will be good info,,if it is just one enclosure or separated top and bottom. I have a bunch of dowel rod scraps that I'll use for bracing,,please post pics of your build!

                      Those are new kits, so I still need to get a cabinet drawing posted. They use 1/2" material, but the baffle is 3/4". I had 3 window braces inside the test cabinet. One directly in the middle, and then one between each of the 2 woofers.

                        Acknowledged- and thank you! ...did you stuff with mattress topper, or [other filler] to calm things down inside?

                          I just put in an order for 2 of these Thursday. Keep us posted on the dimensions / drawing if you receive one. Did the xover schematic come in the package? If we get the package next week we should have them close to finished by the weekend.

                              Yep, all good there- and Erich has updated his web page with details on internal bracing.
