TangBang 3" is dead?

[phobik]

I noticed Zaph as replaced the WS-871 design, with a new one which is said to be multi-purpose - including neafield - but he mentions it lacks low end and NEEDS a subwoofer.

I've also read the same review for the old TangBang 3" design, which led me wondering if they should be paired with a sub - and stop being fullrange - ?

I'm mostly interested in making cheap *cough* nearfield *cough* monitors *cough* and wonder if nearfields are supposed to have a sub? I personally have never seen it.

I got optimistic when I found one of the new replacement design drivers - there are two, the design is intended for B3S, but there is a similar B3N - for aound 9£ which should qualify as both cheap and "do-able" as a DIY project for a broke student and potential upgrade from desktop computer speakers.

But I'm still wondering on the low end/Subwoofer issue. As anyone built the TangBang or the new model Zaph replaced it with, for nearfield purpose with/without subwoofer?

Any input welcome.

um, nope, the w3-871s is alive and well.
seems no one plays with them since zaph prefers the b3s :-(

TB Not such a great deal at $20 each now though.............

I'm doing a shootout over the next few weeks of dual drivers.
That may not help you but it'd be good to know.

dual tang band w3-871 vs. dual peerless vline tg9 vs. dual 4" bamboo vs. dual w4 1-52sd

Now all will be in a .35ft3 lightly stuffed sealed box...............
and remember w3-871s has 32cm2, peerless has 38cm2, and the other 2 have 57cm2. Peerless and bamboo each will need a notch filter.

Tang band w3-871s is phase plugged.
Peerless has fiberglass cone, copper cap, and dust cap.
4" bamboo has shorting ring, neo magnet, cast frame, underhung, and bamboo cone.
the 1052 has a poly cone with stiffeners (and prob break up standing waves), and neo magnet.

Some run baffle step.
That sepends how close to a wall and size of baffle.
I ran a w3-871s on a 2.5' wide open baffle... It'd break up on bass.
When run at same time as a 3 way, it added intelligibility and more coherent bass.

I'd say a sub never hurts, especially if it can clean up the mids.
Trouble is getting clean circuitry................

Fiddling around with active crossover, 24db/octave LR that 200hz was a good place to cross a full ranger. Best mids. Maybe you need a woofer instead of a sub. but good luck finding a transparent crossover.

I'd found a link on a german site where someone still heard the ringing of the b3s even with the filter in. I'd read it is easy to make a tweeter give cymbals a bunch of zing but upon long term listening they'd become irritating.

Remember these are tiny drivers......................
I say the tb is great given low volume levels restraints......................

I look forward to your opinion on these drivers. Enjoy the process.

thanks godzilla,

I still need to buy a pair of peerless tg9 and a pair of the w4-1052sd.

My bets are on peerless.
But any notch network while improving the ringing may remove a bit of magic or life normally found when adding even passive circuitry to a full range driver.

Detail will be the most important factor followed by clarity at low volumes.

Drivers will be run wide open with bass support (f-modded at 80hz ported v12f cerwin vega).

I'll try not to let cone area be a factor, especially with the drivers being run wide open.

I couldn't believe I'd read "These guys also give good weight on acoustic piano, and the timbre they project is very accurate… I mean the acoustic piano really sounds like it should" about a poly cone. Guess those stiffening ribs work. I see them as breaking up standing waves..........And these do bass compared qtc sealed boxes having f3 between 120 and 150hz of the other 3.

Seems omega only doing hemp cones.....
pretty, but not cheap.

Thickness of cone may also be a factor as I know the TB w3871s well in an open baffle, not 2 in a .35ft3 sealed box. Open baffle gave it squeeky clean mids...............

That's pretty much 2/3 of the way to an FF85k which is a much better driver.

Not many 3" will get you under 100 Hz, and even then tend to be xMax limited. This works out fine for nearfield use, and a sub abd a high pass and they can get quite interesting (Chris just delivered the proto boxes for an FF85k/SDX7 20way we are working on )

hiya dave,

whatzza FF86k ?
an ff85k ?
http://www.madisound.com/catalog/PDF...vers/FF85K.pdf

I don't yet have much experience with different drivers.
yet anyway.

sounds neat.
there needs to be more full range plus bass speakers !!!!!!!!

there was a link on ff85k and FW208N (qts .2, fs 29hz)
fostex FW208N and FF85K

or the 871s with woofer
http://www.lautsprechershop.de/hifi/...i/ct211_en.htm

here is a dual ff85k rear horn, cool
http://www.fostexinternational.com/d...e/85k_encl.pdf

and even saw where one crossed 1 ff85k at 24db/octave LR actively.

A consequence of my taking Grade 11 math instead of Grade 10 typing .... FF85k it is (actually FF85KeN -- in truth we just went ahead and modified the driver to start.

Inspired by Cal's Calhouns we have 2 pair of FF85KeN set aside to try in a set of Frugel-Horns -- one on the front & oneon the side

Keep us posted on that one, Dave

Tysen (the FF85 + SDX7) will be playing for the diyFEST... the twin FF85 Frugel-Hor won't make it unless Chris decides to do a blast.

I've tried the WS-871 in several designs and the always sounded "small" to me. Not bad, but just lacking impact and life. Ineffecient, too.

But maybe there is a good design out there for them....
