Vifa (Peerless) Tang Band 2-way in progress pics

[TrickyMike]

Hey y'all. Been away for a while, but not exactly inactive... Just lazy about posting.

Working up a new project based on the Peerless dual ring radiator and Tang Band 4"
I took a bunch of inspiration from Paul Carmody's Speedster, so he deserves a big shout out here.

Making the cabinets out of 3/4 Baltic Birch. I usually use MDF but love the look of Troels Gravesen's stuff (and I despise MDF dust)


Cut a Dado on the back side for the rear cover





The front baffle is Beech and padouk. 1.5" thick before planing.



Speakon 4-conductor. These are going to run active crossovers




Grabbed this 6-channel Rotel on Ebay to run them


Starting to take shape



I think this voids my tweeter warranty?







Recess for the woofer on the back of the baffle. I don't have a circle jig so I do my circle cutting with a big Troyke rotary table on the Bridgeport



I was given a nice Delta planer that needed some TLC. new knives are nice and sharp



Adding a little more padouk for color



This didn't end up working...


This DID end up working ;)







Getting there:




More to come. Thanks for looking.

Very nice. Looking forward to the rest.

I want to see many pictures of these finished. They should look awesome!

[mmbone4]

Nice build...love the in-laid corners.

[ceiol]

looking good!

[TrickyMike]

Thanks!
Still not too sure about finishing. I think I'm going to spray them with Urethane clear, but the recesses I cut for the drivers are pretty tight and I'll have to get creative about how I mask them. I'm afraid that if I get any clear in there the drivers aren't going to fit back in and I'll have a problem I need to fix on a nice, shiny finished box. Should be able to avoid that with some clever masking, though.

I'm running a MiniDSP 4x10HD and that last piece of the puzzle should arrive on Friday. That might light a fire under me this weekend.

[TrickyMike]

Wrapped these up over the weekend.

Mmmm... Clampy



I added some threaded brass inserts for adjustable feet.



A sharp forstner bit works wonders



Ran into a bit of a snafu on the router table.



Thankfully I had some scrap padouk left over and cooked up a sawdust/titebond filler



Fixed!



Ended up spraying some House of Kolor UFC35 clear on them.

















4- conductor Speakon makes dealing with multi-wire active crossovers much more tidy.





Currently crossing them at 2500hz, LR 24db/octave. No EQ and they sound great. Great low end in such a small box (.207 ft3). That Tang Band 4" delivers.

Haven't measured them yet. Hoping to do that tomorrow. I'm running toslink digital into a MiniDSP 4x10HD. Analog out to the Rotel. These will live in the office where they'll be joined by a dual voice coil Design Acoustic sub powered by a Parasound HCA-1200. A little overkill there, but a little headroom never hurt anyone.

pretty

[thekorvers]

Beautiful. Very classy.

[TrickyMike]

Thanks y'all!

[tomzarbo]

Beautiful! They came out real nice.
Nice solution on the filler, I had not thought to do that, but it's a good idea.
I LOVE your clamps, jealous of them, I have a collection of HFT ones that do the job, but then again, I've never laid hands on clamps that nice.

Very nicely done.

That is a beautiful job well done!

[Kornbread]

Ya know how much I hate all you guys that make really nice looking speakers, and make it look so easy ...

Really nice job.

Something someone else on here posted, that I'm going to try on the next build, that might look good on yours; use a small blow torch to blue the stainless steel screws holding the drivers in place.

Funny you mention the screws, that was the only tiny criticism I could come up with. That cabinet wood work is amazing... those silver screw heads would just nag at my OCD

With or without silver screws... damn fine work TrickyMike!

[TrickyMike]

Ha, yeah, I feel the same way about the screws. :D I didn't have any black screws of the right size. I'll probably powder coat a set over the weekend.
