Hi guys. I have only a lurker here at DIYauio (mostly in the analog section though) and have decided to build my first set of fullrangers. I bought some Tang Band W4-1052SD's and have used WinISD (well there online calc, I use linux and didn't want to bother trying to make it work) to come up with some figures for a box design and wanted to run my thoughts by you guys to see if I'm somewhat on the right track
.46 vb
58.59 tune fq
.07 acoustic power
2in dia port 2.3in long
I got the acoustic power rating by putting in the 15 watts of power per channel they will receive.
Now by my calculations I should get a vb of .461 with these outer box dimensions using 3/4" MDF
14" high
9" wide
10" deep
I just didn't know if I needed to take into account that I was building ported speaks in the volume formula.
Thanks for any input, Nick

I have some w4-1052. I have used WinISD
I get 0.357 and Tuning Freq= 58 using datasheet parameters.
which T/S parameters did you use ?
I get the same values using the on-lin and the windows version so you don´t need to worry about vents. The calculated volume is the volume of the box.

First post here, but I've been reading a lot and this thread actually sparked me to make an account. I'm actually getting the same speakers but I'm going to use a BIB design (Bigger Is Better 'BIB' Cabinet Dimensions - ZillaSpeak) with the W4s. There is an excel calculator you can use to calculate overall dimensions and whatnot, with the W4s, the cabinets (which are floor-standing) ended up around 4 and a half feet tall. Just thought I would throw out another option for you, and make sure to keep us update with whatever you decide to do!

I have noticed the T/S parameters in the excel BIB calculator are different than the official ones (Tangband Speakers) for the W4-1052SD
whit the officialparameters the BIB box is a little smaller
whit the officialparameters the BIB box is a little smaller
You are able to change the parameters in the calculator to whichever driver you want to model, then the other info changes accordingly to tell you the optimum dimensions and whatnot.
Note the model name difference. The Excel sheet was generated when TB was on an earlier 'version' of the same driver, the 1052SA, so the TS parameters are slightly different.
Any updates? Starting making the cuts for my BIBs with these drivers today, hope to have them mocked-up for listening in a few more....
Hi, just for your infomation. As we speak, I am building another of my TABAQ cabinets to be tested with TB 4" 1320SB. Same construction as the 3" driver. According to the simulations with Martin J. King´s software, the 4" drivers should do fine in this construction. I want to compare TABAQ with 3" and 4" drivers.

Well I have had my BIBs with these TB W4s completed for about a week now (minus putting a finish on them, but I'd rather be able to listen to them!) and I must admit I really like them a lot. My room isn't very great for listening and being able to set them up but I still like them a ton. I have them paired with a MCM 8" sub in a sealed box thats about 1 cu ft. but that's not to say I wouldn't, and don't, enjoy them without the sub when I want to be a little quieter. The treble isn't "sparkling" but I rather enjoy the more relaxed treble and they extend surprisingly low. All in all, for the $50 speakers, and the $15 for the OSB I used on the enclosures, I am very happy with the results and it was a great first project for me. Anyone else have any projects completed using these?
I find the W4-1052SD to be a bit much to handle without a contour filter to tame its rising midrange response. A rear-loaded horn could take advantage of this to balance out the horn's own efficiency through the midbass. However, I was looking for a much smaller and simpler way to try the single-driver concept, and I didn't want to compromise on flatness of the speaker's response, so I applied a contouring network to the driver in my Whetstones project, which is a small reflex-loaded desktop monitor. The W4-1052SD has quite a bit of available excursion, and in a reflex enclosure tuned between 65 and 70 Hz it can deliver surprising bass performance. My contouring filter optimizes the system's response over eight octaves to within +2/-3dB while preserving the system's minimum-phase behavior - all the way out to 17.5 kHz on-axis. A friend and former Magneplanar MMG owner commented, "These things image at least as well as my Maggies."

An externally hosted image should be here but it was not working when we last tested it.

Here is a crappy shot of my current setup. The bass rolls off fairly slowly with them, and paired with the sub I enjoy them a ton. I'm still breaking them in some, they aren't fatiguing at all to listen to. I will be putting a finish on them this summer, as these are at home, and I head back to college in just a few more days.
