    Anthology build

    This may be a somewhat short build thread as I have all of the pieces cut, all of the window braces are done, and the tunnel parts are cut as well.
    I will post more pics tomorrow on those pieces.
    I purchased these as a kit from Meniscus and opted for the finished crossovers as I thought for what they charged for them was very reasonable and worth the time saved.
    Anyway, here are some pics of the crossovers and will have more over the weekend.
    Ardents will have to wait until these are done, drivers are a ways out anyway.

      Hey Jim, what adhesive did you use to secure the PVC to the MDF for the tunnels?

      Thanks, Greg

        Hi Greg,

        I used plain old Titebond III. Everything fits tight and the Titebond seals it in.

        I'm looking forward to following your build. Meniscus does a really nice job on the crossovers, IMHO.

            My plan was to spend the whole day on these on Saturday and REALLY make some serious progress.
            Well, that didn't happen and yesterday was out due to Easter.
            Anyway, did manage to get one hurdle behind me with the midrange tunnels.
            I decided to build them as a separate assembly.
            I also epoxied them together with some good epoxy (not the 5 minute type) to add some structural integrity (brace) and wanted to make sure that I would not have any loose joints down the road.
            Anyway, these builds never happen as quick as you think our would like them to goClick image for larger versionName:	103_1201.jpgViews:	1Size:	63.5 KBID:	861556Click image for larger versionName:	103_1202.jpgViews:	1Size:	29.2 KBID:	861557Click image for larger versionName:	103_1205.jpgViews:	1Size:	36.7 KBID:	861558

                I hadn't seen photos before of Meniscus crossovers (hadn't looked). Those are really nice looking crossovers. Makes me feel good about sending people that way from time to time. Thanks for posting.

                  I had them do the crossovers for my Statement II center as well.
                  They do a very good job that is well worth the cost

                      No Jim, have not got back to them.
                      I have been busy with a turntable project and actually have finally received the parts for that project today.
                      I am going to get that assembled tonight and out of the shop and get back to the speakers tomorrow.
                      What was that comment about being a quick build?
                      Oh well got to go with what pays the bills first I guess.

                        Life has a way of getting in the way of fun.

                        I'm looking forward to hearing your comments when they're done plus you are doing a great job of documenting the build which I'm lousy at.

                        Thanks for responding.

                          Finally got back to this project.
                          I always secure my baffle to another sheet of plywood or MDF to cut the driver holes.
                          I put two screws in each driver cut out (WELL WITHIN THE INNER CUT OUT DIAMETER) I also run a couple of screws into the baffle from the backer board.
                          This makes it very easy to re secure the baffle accurately in case you have to some additional routing.
                          This does take a little extra time but can be very helpful if you have to make some adjustments.

                            More progress.
                            Front baffle, inner baffle and back panels all cut.
                            That is a lot of holes to cut.
                            First time building with Baltic birch, glad I started out with a new router bit.
                            Now where did I put my Elmers glue?

                              I would to like to throw something out there to any future builders of these speakers.
                              If you decrease the depth of the sides by the nominal width of your material and cut the inner and outer baffle the same width, It will make the build a little easier.
                              This way you can make the two pieces of the front baffle as a separate assembly and glue it on last.
                              You could also cut it slightly oversized and flush trim it.

                                A little more progress.
                                Upper mid tunnels are glued in and everything is true and square to the world, down hill from here.
                                Oh, except for the veneer and finishing.
                                Unca Jim, I have a couple of questions for you;
                                First, the schematic I got from Meniscus showed both the mids and tweeters wired with reverse polarity.
                                Just want to verify this is correct.
                                The other question is, what are your thoughts on the contact cement you originally used.
                                I do all my cabinets with Heatloc and have had very good results.
                                My original Minis are going on 6 or 7 years now and look the same as the day I finished them.
                                Just wondering if you think it is any better/faster.

                                Thanks, Greg

                                  Hi Greg,

                                  Yep, reverse polarity on both the mids and tweeter.

                                  I've been using Titan DX from Joe the Woodworker but it sounds like you have a winning combination with a proven track record so if I were you, I wouldn't change a thing. Go with what works best for you.

                                  Jim


                                  Here's the Anthology crossover;

                                    Thanks Jim.
                                    That is a better reference sheet for the crossover than I got from Meniscus.
                                    Anyway,THANKS FOR YOUR HELP.
                                    Hopefully I will have them glued up and ready for veneer, by next weekend.

                                      One inner front baffle glued on, damn that took a lot of clamps

                                          Hey Jim, I was kind of looking at fitting the crossovers and was just wondering where you ended up mounting yours.
                                          I dont know if that you may have built yours differently than the boards from Meniscus, just wondering.

                                          Thanks, Greg

                                            Hi Greg,

                                            I built the crossover on one board the width of the RS225 cutout and deep enough to make everything fit which, I think was about 9"-10" and then positioned it on the brace below the bottom RS225. Obviously, I don't glue foam to the crossover. Bare is fine since it can't reflect sound waves back into the driver.

                                            Since you have three boards, I'd either position them together as I did or mount one on each side panel and one on the brace with foam surrounding them.

                                            Don't forget to drill holes in the PVC tunnels for the wiring.

                                              Thanks Jim, I have not drilled the holes yet but have a note written right on the outside of the cabs to do so.
                                              I have everything glued up except for one side on each cabinet and the outer front baffle.
                                              I am going to mount my crossovers and build the wiring harness for each one before I glue the side on as it will be a little easier.

                                              Thanks, Greg

                                                Ok got back to this project and here is what I have cooking.
                                                All of the crossover boards that Meniscus built will fit into the port tube hole.
                                                Removing/reinstalling them though might be a trick once the cabinets are assembled as it is a one handed operation.
                                                I ordered some grommets to fit a 5/16 dowel, and plan on securing the boards with one fastener.
                                                I did a closed eye test and it was very easy to reference them.
                                                My OCD, OH WELL

                                                    Jim, just wondering how you ended up lining the port area.
                                                    I have several options available, 2" egg crate, 1" flat foam, Accusistuf.
                                                    Anyway, Thanks, Gregi

                                                      Hi Greg,

                                                      I didn't line the port area. There's no way to reflect sound waves into the back of the driver from the bottom of the cabinet. The foam is just to kill reflected sound waves so it isn't necessary.

                                                      Jim

                                                          Jim, what material and how much did you use in the upper tunnel area, inside the cabinet.
                                                          I was going to use Accusta stuff @.50 lbs per cu ft, looks like too much.

                                                              Hi Greg,

                                                              The stuffing is completely optional. It doesn't kill any resonances in the top half of the cabinet and only make the cabinet appear a bit larger than it is. I had a couple bags of accusta stuff (furniture stuffing) from Home Depot that I think are about 16 oz. laying around so I put one in each cabinet in the top half. I'd use the "TLAR" (that looks about right) method that I learned from Curt to judge how much stuffing to put in. I filled it but don't wad it up. Spread it out in the cavity and it'll be good.

                                                                It looked better after the volume compensation.

                                                                      I decided to do these in hickory and I am going to just going to use clear danish oil and poly.
                                                                      Maybe not for everybody, but that's why I decided to go this route.
                                                                      It took quite a bit of time to roll out the heatloc, but it is the method that works for me.

                                                                              I thought I would post a couple of pics of my process of preparing the veneer for the heatloc.
                                                                              I like to cut the veneer 2 inches over the dimensions of the cabinet surface I am going to apply it to.
                                                                              I know this sounds like quite a bit more than you should need, but it allows you to adjust the piece to book match the grain with previously applied pieces.
                                                                              Also, it allows some room to tape the piece to another surface to prevent any of the heatloc to get on the finish side.
                                                                              As you can see in the pics, I have taped them to a piece of 1/2 inch plywood.
                                                                              This provides a nice smooth surface and is relatively easy to get an even coat of heatloc.
                                                                              I always mark the pieces with a piece of tape when I cut them to make sure the wood grain stays orientated correctly with other pieces.
                                                                              Also, I may be behind the times, but I found that the Whiteside down cutting spiral bit is worth every bit of the $43.00 I spent on it.
                                                                              Very clean cuts that are very precise requiring minimal sanding.
