    Build - Tang Band W6-2144 Full Range Towers

    Not sure really where to park this, but could be fun to share my somewhat chaotic process as I dive into a relatively simple speaker build.

    These will be full-range initially, though it won't surprise me if I feel they need a super-tweeter and simple crossover when they're done. The intent is to have them at my office with a vinyl rig ahead of them. Probably a streaming device as well. Amplification will probably be tubes...to be determined later.

    Anyway, they're designed/drafted over a cup of coffee or 3 about a week back. Woke up this morning and decided today's the day to start knocking out the cabinets. Constructed of relatively thin (too thin) 12mm baltic birch, however, there will be substantial bracing, damping, etc. in this simple bass-reflex box with down firing port. I think they'll work fine. The bezels are some stupid expensive hardwood I bought a couple of years ago. I think it is African Blackwood but don't recall for sure. I do recall that the single 38"x8"x.9" board was over $60. Internal wiring will be simple - but quality, and I'll likely use tube connectors from GR-Research as I have a set on hand.

    The feet in the rendering are just place holders. The corners of the cabinet will be machined aluminum, or maybe a different hardwood. The cabinets themselves will be sanded, filled, and painted (matte or texture finish most likely). I've even played with powdercoating wood - it is totally doable but I won't go that route on this project. Saving that for a future build (something I started about 18 months ago that is just waiting for me to give it attention, drivers from a classic set of Polk Monitor 7's along with substantially upgraded x-overs). The red paint will be darker than the renders here - think more of a merlot shade...or hell I could change my mind at the last minute and use whatever we have stashed at the shop (not black!).

    So, place holder, and as time permits I'll bore those of you interested with the details. DIY speaker building is an old hobby of mine, something I was never all that good at (save for kick ass sub boxes, sealed, bandpass, and more) but something I've always enjoyed. The router took about an hour to chop out the baltic birch panels, and about the same time to 3d route front and rear the hardwood bezels. If I decide to produce the corners from aluminum that will be a day of messing around on one of the VMC's. Just now, while typing, the thought of acrylic corners with internal LED lighting popped into my head too...hmmmm...there really are no limits.

    No, the Prime Rib below has nothing to do with this project - however, on the RecTeq for ~6 hours with a 500+ degree sear beforehand for 20 minutes, it's flat out epic. None left. Everyone said best Prime Rib they've ever had

    Mostly finished bezels. Had some failure (should have done more pretreatment and filling of cracks before going after the router work today). Not shown, but backs have large radius clearance...and dimensions. These are about 40" tall, 8" wide and 14" or so deep.

        Love the wood pick. Never heard of that wood. Must be pretty dense. For sure, I would make it a true 2 way speaker. Don't want that 6" driver doing all the work, especially with that whizzer cone. Lots of debate on which order crossover to go with. But yes, minimum 1st order filter on each driver. For high end audio components [L, C, connectors, etc], shop around at Michael Percy. He's old school. So, ordering is done by email or phone. You can download the catalog here: http://percyaudio.com/

        Are you using dual drivers? Looking at the specs, it needs a ported volume of 1.5 cf. I think F360 can calculate volume.

        If you need any help on the crossover design, let me know. I can even layout the PCB if you want, to mount the components on a board. Hell, I'll even simulate signals. This should be fun!

          Thanks, Eric. Good points. I've used similar full range drivers before with decent results (a lot depends on the source and signal path ahead of the box). I have a life long friend that spends his days engineering drivers and boxes and then having them mass produced (often with labels for names we know) at one of their trusted overseas facilities. In the past Oliver has assisted with xo design but I'd happily reach out to you if I go that route. I modeled the cabinets based on published specs and came up with a bit more than the 1.5 cf recommended by PE and other locations (1.6 cf - didn't measure these actual drivers).

          I'm not a novice to x-over assembly and design, but the goal of a full range speaker is to avoid all that. I might employ DSP (sacrilege!) but that remains to be seen. The Polk 1.2TLs have massive upgrades - using gimpod SDA circuit boards (http://www.gimpod.com) and VR3 crossover components. Still need to finish those builds/restorations but they are really great as is - so no real rush. Actually, the Adcom ahead of it needs to be upgraded or replaced next...and That's another subject entirely. I should drink more coffee before I type.

          Thanks for the link to Percy audio. Been awhile and that is part of my memory bank that purged. That's the joy in all this - there are so many possibilities.

            True, XO will be a compromise. Didn't think about that. I always steered towards drivers that were not full range and they just did their part in the frequency range (subs, mids, tweets) and just figured crossovers were just assumed to be part of it, passive or active.

            Adcom, what a throw back name! They were great value high end components back when I didn’t make much dough. I always picked stuff based on Recommended Components list. Remember that mag - Stereophile!?

            I need to look for that Blackwood. Got me intrigued.

              Oh yes, I remember Stereophile and many, many others. Having built a handful of speakers in the past (2 way monitors, MTM designs, line array (failed) and more) I'm keeping this build simple. There is still a stash of decent Dynaudio drivers and tweeters in the garage for a nice 2 way at some point (likely small stand mounted with a servo-sub). I'm in no hurry to complete any of these.

              Stage 1 glue up of 2nd cabinet completed this morning. I'll get back on these tomorrow.

                Posting so I can follow this build.
                Back in the day I had a sub to Stereo Review that I read cover to cover.

                Your build looks like it will be tons of fun to complete and even more fun to enjoy once you're done.

                  I've only read about the Dynaudio. Always wanted to hear them as they look to be quality built. That will be a nice setup too.

                    I have always - always - always regretted selling the Dynaudio Geminis. I had built the upgraded crossovers (Gemini Done Right - Bamberg Audio I think) and had a SunFire True Subwoofer, on this same Adcom GFA-555 amp (sold this amp, and it made it's way back to me, randomly, through an internet purchase some 10 years later - crazy how the universe works). For small MTM speakers the bass was impressive as hell, and they can handle an awful lot of power. Imaging and overall sound quality was no joke either...but...when my first son was born and he almost toppled off the stand and onto his head, I decided to sell those bits on and go a different direction.

                    Side note: One of the best classic speakers, IMHO, is the Polk Audio Monitor 5jr. You can often find them for $100 a pair, and I highly recommend them. Small xo tweaks is all they really need...and a nice clean amp upstream.

                      I have always liked Polk Audio speakers.
                      My former home theater setup was all Polk satellites with a 15" AudioSource self powered sub.
                      It was a great setup.

                        Very fucking cool dude!!!

                        I know it's probably not satisfying to blow the mind of a man who can't build an under seat box for 10's, but still. Mind blown!

                        These going in your living room i'd imagine? To pretty to hide them somewhere.

                        Powder coating wood, huh? Can not pretend that's a sentence that makes sense to me, but I'ma just pretend it makes 100 sense to me. Yup. Good idea.. I'm with ya.

                        Looking forward to seeing this come along. More inspiration and motivation to stay in my shop and off YouTube this winter.

                          Quick update. Finished cabinets V1.0 - and along the way decided I can do better. V2.0 has been drafted and programmed. Next chance I get I'll router them out.

                          These will be kind of showpieces at the shop most likely...we will see.

                            Can't wait to see the pics of the new and improved versions.

                            I used to go to CES every year and my favorite part was taking the bus over to the hotel where all the high end audio gear was and just being amazed at some of the outrageously nice equipment that was absolutely everywhere.

                              I was under the assumption that Audiophiles had to register with their neighbors if they were within 200 yards of the closest house ⁉️
