Dear all,
after building a pair of Lancetta's I am looking for a small sub to support them.
The idea is to build two small subwoofers with the Tangband W5-1685: click Is it possible? Or should I go for the W6-1139SG or W8-740 which are actually designed for subwoofer use?
First results with WINISD:
Vented box, volume~21 liters, tuning frequency~43 Hz, though I'm having some troubles with the group delay, which is too high.
Any suggestions?
Kind regards,
Coen

I have no experience with the w-5, but yes I would seek a driver intended for sub duty. I built some tapped horns with the 1139 that perform well. I've also been tinkering in winisd with the 740, as I bought 2 for cheap on cyber monday. Sims are promising- 0.75ft3 sealed, factoring in 6db boost @ 30hz and a lowpass @ 80. I tried simulating ported but the driver specs call for such a long port it wouldn't be possible to fit a port in a modest sized cab.
Here's the sealed response.....

W8 could be both vented and sealed. I read somewhere it could be 5 liters sealed or 10 liters vented (f3=41 Hz). Going to try this myself with WINISD. I will post some results soon.
