Default TangBand 3" and 4" driver box-ideas?

My inexperience is frustrating...
I picked up a couple of different pairs of TangBands and am looking for some ideas on what to do with them. One pair is W4-657SH 4", and the other is W3-879S 3". Using speaker workshop and winISD, the vent is supposed to be over a meter long in a box that's roughly 3" x 4" x 2.5".
Any suggestions on making a speaker box for these drivers that's more reasonable in size? Maybe combining the 3" and the 4" in a box?

W4-657SH: Power Handling: 30 watts RMS/60 watts max *VCdia: 1" *Znom: 8 ohms *Re: 6.0 ohms *Frequency range: 65-16,000 Hz *Fs: 65 Hz *SPL: 88 dB 1W/1m *Vas: .22 cu. ft. *Qms: 3.32 *Qes: .43 *Qts: .38 *Xmax: 3 mm *Dimensions: A: 4-15/16", B: 3-3/4", C: 2-7/8"

W3-879S: Voice coil diameter: 3/4" * Nominal Impedance: 8 ohms * Re: 6.6 ohms * Frequency range: 105-20,000 Hz * Fs: 105 Hz * SPL: 86 dB 1W/1m * Vas: .06 cu.ft. * Qms: 7.22 * Qes: .65 * Qts: .59 * Xmax .5 mm * Dimensions: Overall Diameter: 3-5/8", Cutout Diameter: 3", Mounting Depth: 2", Magnet Diameter: 2-5/8"

I've thought about a BIB, but I'm hoping for something smaller.
Thanks,
Mike

Isn't the W3-879 basically the same as the W3-871? If so, there is a lot of info and projects in the Full-Range section.
(I never cared for the W3-781 as a full range).

The W4-657SH should have its fans, too.

I like the box above for my 4" TB drivers.

With the 3" TB drivers i've had good success simply using sealed boxes of reasonable size.

I cut up the wood to build a BIB for the 4" driver but never built it.

re:'the vent is supposed to be over a meter long ' - !!! - reduce the diameter & try again...

I used the TangBand W4-1052SD in a TABAQ design: TABAQ TL for Tang Band

There's a few other threads if you search, and it seems most 3 or 4 inch TB drivers seems to work well in that enclosure.

I'm very happy with the result, and very easy to build and they are small and narrow -- which was necessary for my particular application.

The size for a traditional vented box for the W4-657 is around 4L, and the vent can be 1" diameter, tuned to taste (60-80 Hz). I nearly used this driver in the past, but went for the W4-656 instead.

i believe Henkjan has a nice desktop TL for TB drivers which may also be worth a look.
