TABAQ TL for Tang Band
Did u use the BSC circuit on + side?, (3,9 ohms and 1.0 mH in parallel). I am confused by 3,9 ohms, or is it 3.9ohms?, these parts available at Partsexpress?

thanks,

gychang

Hi all.

Where are you guys buying these speakers? I'm in Europe, Finland to be exact and I'm looking for a source to get my hands on a couple of these for my first speaker build.

The W3-881si's are sold out at Parts Express in the US. I think they are now available on ebay. If you like this driver you may also be interested in this quad driver bipole MLTL: Tangband W3-881 MLTL build

This is an old thread, but I'm very interested in the nanotower design. Do you think the Tang Band W3-1053SC would work well in this nanotower design? Any thoughts appreciated. Single-driver high-performance speaker systems are something I am completely new to.

All the Best,

Brian

The W3-1053sc driver is quite nice but you may get better results if you use the AMLTL technique to size the port and volume for better performance.
Accidental MLTL Technique

My guess is that the volume of the current nano tower is too big for the lower Qts of the W3-1053sc vs the 883si and will force the tuning to be unusually deep circa 40 Hz. This will cause a very depressed bass output vs the rest of response. Change the tuning closer to 55 Hz and adjust the cross sectional area to get a volume closer to the ideal volume recommended by a bass reflex calculator.

Of course, this can be modeled very easily to find optimum cabinet and vent size.

Thank you for the good information. The 883si is a little more expensive now (about $26 each), so I was looking for a cheaper alternative. The originality of designs in this forum are simply astounding to me. I'm looking forward to starting my own project soon.

Best,

Brian

The nanotowers are finished and working! They are currently in the unfinished side of my basement where most of my "messing around" work takes place. I used Tang Band W3-881SJ 3 inch neodymium drivers. I have a video of them being driven with a Dayton DT100a. The source is a laptop running JRiver to a small, external DAC. The ipad does not do justice to the quality of the sound. The transparency and imaging are quite outstanding. Thank you to everyone who helped me with good advice and thoughts. And, of course, a big thank you to cogitech for his help here and via PM.

I'm thinking of using them outside on a covered deck. Do you think the drivers are up to outside conditions (I have covers for the speakers)?

The video is here:

Thanks and Best,

Brian

Nice job, Brian! I will watch the video at home with my main sound system for audio, since I am sure my laptop is not doing it justice.

I think the drivers will be fine outside, as long as they are not exposed to direct rain/snow.
