      Beau, the 5" close-out mid-woofer doesn't go very low and likes a pretty large box. I had eyes on it myself.

      It makes a big computer desk speaker, but a TMWW based on the parts mentioned look like they could play well together in a four ohm speaker. Where you hand-off the mid to the tweeter could be touchy for voicing, unless you can stand the extra cost of a higher order tweeter filter. That's what I got in my REALLY quick-n-dirty sim anyway, using published data and TRACE.

        Are you thinking of the MDT 40 Ben?

        But I wonder what you could do with those components????
        T'was funny. I think it could be a great entry build....

                Will it be truly modular, mix-n-match speaker components? Looks like building block design possibilities to me. ;)

                  Is that space above the tweeter for aesthetics?

                    That's no barrier to measurement. FuzzMeasure is probably the best overall measurement package out there. It does everything except for polar maps.

                      Thanks fellas! I borrowed the basic idea from my HT builds. I thought it gave some nice detail to it.....

                      My first thought was to just dado an 1/8"x1/8" recess around the whole enclosure to give the illusion of separate blocks, and as I was drawing it, thought that would be a really cool idea. . I have some ideas for it, though not sure which way I wan to go. I think the modular idea would be different....kind of.

                      Purely aesthetic. Thought it offered balance to the overall design. Have an idea regarding?

                      Thanks Pallas! Is the free version worthwhile or do I/ should I purchase "Pro"?

                        Speaking strictly from a performance standpoint, I'd put the mid up high, and leave about 1.25" between the hole, and the inside surface of the box top. Then the tweeter could be at the divider between the woofer and mid. You would need to carve out some space for it. This should leave some space for the 1" fiberglass panels on all sides of the mid driver.

                          Kim, how close to the baffle would you put the OC703 around the mid? I know it needs room to breathe but then squash the rear waves. If I am setting the OC703 back 1.5" to 2", do I need to add space around? Also, does it matter how large the chamber is for the mid?

                            I'd place the 1" fiberglass against the walls, or floating loose, or some of both. Try to keep any sound from directly bouncing off the walls and back to the mid. I usually cut strips about an inch or two wide, and the length of the chamber. Then I push them through the cutout, and position them. If they wedge and hold in, that's ideal, but I usually have some that are just thrown in at random. The daycron pillow stuffing can help hold them. I would try to cover over half the walls, but 70% to 100% coverage would be just as good, maybe better. I've not tried carpet in a long long time, but it may be a good alternative. I've also used mattress foam.

                              I'd like to keep the mid in the middle, not for much more than aesthetics. Also, I thought modus operandi was to keep the tweeter as close to ear level as possible?

                                Good point. Make the box taller for me! I might would slope the front too, although if the tweeter is below the mid, and below ear level, it would tend to tip the listening axis upward.
