Default New TB for 2015

Just got an email from TB and they were showing new 2015 models.

Here it is:

1. New full range serie – from 6.5” to 8”
W3-2141
W4-2142
W5-2143
W6-2144
W8-2145

This series has very nice performance full range, we make them in ferrite magnet version, it should be categoried into economic models..

2. More “module” be developed
T1-1828SD – square shape in alum. Cone. Passive radiator in
the backside.
T1-2121SD – rectangle shape design, increase power
handling.

Module = speaker box, which is getting popular in the market, with passive radiator design in a sealed box, it widen application possibility from portable speaker, multimedia to soundbar system. It is a total solution for most of application includes cross-industry application like LED light bulb, furniture….. You only need to focus on designing amplifier functions and ID design of finished products.

3. Micro speaker – we increase its size from 1” to 2”
W1-2121S – high power handling, consistent quality
W2-2136S – good linearity, consistent quality, good low fo.
W2-2181S - – good linearity, consistent quality, good low fo.

Recently, we developed many micro speaker, those are

4. Low distortion Subwoofer - 3” and 6.5”
W3-2108 – thinner basket than W3-2088S0F
W6-2100 -2014 we already had 2” – 8”, but we miss 6.5”, so we add it here.

This series subwoofer have extremely linearity and low distortion characteristic , dual surround and no spider,

The module etc. series hold about as much interest for me as The Only Way is Essex; the others look a trifle more so though. Spec. sheets for the W3 - 8 are on TB's site:

http://www.tb-speaker.com/detail/1230_04/w3-2141.htm
http://www.tb-speaker.com/detail/1230_04/w4-2142.htm
http://www.tb-speaker.com/detail/1230_04/w5-2143.htm
http://www.tb-speaker.com/detail/1230_04/w6-2144.htm
http://www.tb-speaker.com/detail/1230_04/w8-2145.htm

They look nice enough aesthetically, although personally I don't much like the shiny santoprene roll-surround & I can't imagine it'll do the off-axis response many favours; the published impedance curves on the data sheets suggest that there are some resonance issues from this, probably reflections, although we shall see. I do like the colour of that bamboo derived paper. The phase plug reminds me of tuning dials on 1970s era receivers (I quite like that). Possibly solid extension; be interesting to find out.

On paper the specs. appear reasonable for what they are; W3 has a very low F0 + moderate Q -looks like they're trying to do a Fostex wk style driver with a bit more low-end. Don't like the HF rise -theoretically. That may smooth out off-axis though & TB's graphs have historically needed to be taken with a pinch of salt. Be interesting to see what transpires. W4 much the same -Q's a bit lower though & the top end seems a bit disappointing, but since it goes off the scale, difficult to say. W5 looks promising; nice balance of spec. for a variety of cabinet types, response doesn't look too bad on axis (with aforementioned caveats). The W6 & W8 are interesting, although the whizzer cone on the former looks from the pictures to me like it might blank off part of the main cone off-axis, so might be an issue depending on where the mechanical XO is -from the look of the impedance curve I'd guess about 2.25KHz. All in all, not without interest.

Hmm, w4-2142 - I'm wondering if this works with BLH or BIB enclosure?

The BIB is a back horn.

They'll all work -just a matter of degree.

Looks like they are gunning for Fostex. I like everything but the thick rubber surround.

They are an update on the designs with that weird fake copper phase plug.

I think they missed a trick not having a 6" without the wizzer - the 5" wd be great with a bit more xmax

also they don't look like neo magnets but I guess they must be if they say so

edit def ferrite, must be reusing modified spec sheets

Probably; they're certainly ferrite magnets & this is noted in a couple of the sheets. Presumably the subediting missed that in the others.

I like what TB have done with the plug, I know there's a consensus that any kind of phase plug in a wideband is a bad thing but what the hell, it looks nice. I like the look of the white cone with the silver plug but def not keen on the shiny surround.
Guessing the 4" will be popular as a mid as well as FR, the 5" as a ribbon companion in a 2 way. Both have flat response up top, if the charts are accurate
Its a shame they don't look to have much cone travel, altho maybe the xmax rating is misleading.
