            Nice design. I like the dark stripe down the middle too. Kind of like speaker "racing stripe"

                Some build pics for the center. The front/rear/side walls are .75" edge glued pine found at Lowes, and the bracing/top/bottom are .75" AC Fir plywood also at Lowes. Supporting a 100lb TV was one of my main design considerations when planning the cabinet construction. The -l-l- brace allows me to easily separate the TM's air space and reach my structural goal. The braces behind the woofers are "house" cut to allow the massive TM xover board a place to sit. There's ample internal volume, and this box could easily be ported or made shallower if one desires.

                Regular high tack masking tape should NOT be used on wood like this! I've gotten pretty good at recovering from my mistakes, but man was I livid when I de-masked and saw that.

                The finishing system for the matched LCR. 4 coats of oil gave me the semi gloss sheen. I only wiped off the first coat applied, the rest were left on, and applied every 12 hours.

                  Again, .75" edge glued pine is used, and .5" AC Fir ply for bracing, The front baffle is of the 1" thick variety. I made it simple and used the 12" wide panels, so the front being 1" thick and the rear .75" gives the 13.75" cabinet depth. There is a slight variance between some of these panels, and one just has to grab a tape measure and make sure all the panels are the same width when purchasing.

                  one of these for each side

                  Use a 72" peice for the rear, and there will be enough excess for the top and bottom peice.

                  The 1" x 24" x 48" edged glued product doesnt appear on their website anymore? This was cut in half and used for each baffle.

                  My preferred method is to glue up the sides/top/bottom first

                  Simple window pane braces. Easy and effective

                  Bracing was cut to match the size of the top/bottom panels and then press fit/glued up. The brace against the TM section is only half open, the TM is of course sealed. The extra volume at the top of the cabinet is needed to reach 2 ft3 for the woofers

                    Re: The Nova Forte mains and center project

                    Why the series resistor on the woofer? That's not really a good idea.
                    My typical thoughts on this tweeter selection aside, that xover is steep and high enough it may not be that bad.
                    Sim looks solid, so glad it worked out for you!

                        Nice job on the finishing, it looks good

                        I agree with wolf on the series resistor. I don't understand why you have all the drivers padded, that is weird lol. If the sensitivity is too high and the impedance low you could wire the woofers in series. A series resistor on a woofer is likely to get pretty hot also.

                        The mid is interesting, any opinions on it?

                            A parallel resistor may lower impedance. Is your amp comfortable driving your speakers at 3 ohms or lower?
