Best Woofer s for DIY speakers

Depends a lot, too, on how much you are able and willing to spend. There's also the other driver(s), crossover and cabinet. Also to consider is whether you have any preferences for size and technology (sealed, ported, transmission line, or horn-loaded enclosures), sensitivity, which influences what amplification is appropriate (the range seems to be from perhaps 86 to 100 dB/w/m), frequency response ("monitor" or "full range" -3 dB @ 20-30). There's also the possibility of using used/vintage components (Altec, Tannoy, JBL, etc.) or using very expensive new components like TAD---although the four previous are all high sensitivity (efficiency) drivers that require ported or horn-loaded enclosurres. . . .Having said that, I have a pair of 15" two-way Altecs in the original sealed enclosures and they manage 94 dB. . .Have a lot of fun, whatever you get and whatever you build and keep us posted!

Dr Joe, you are not Joe D are you??? Wouldn't be surprised if it was you. Sneaking around this site with us. Ready to lend a hand...

Carbon Fiber, Carbon Fiber, Carbon Fiber!!!! I had a buddy do a comparison test between many different brands of woofers which utilized many material topologies (stuff like kevlar, Polypropolene, etc). He found one thing in common with the carbon fiber varients that he tested: They were much less colored in the upper bass/lower midrange frequency regions, than any of the other materials utilized employed in the the other woofs.(Unless you plan on crossing over your woofer below 100hz, I strongly consider going with a carbon fiber unit). If I recall, the Vifa was deemed the best overall sounding driver.

definitely Manger!!!

check it out, do a web search, Manger is in Germany

manger makes full-range drivers from ~160hz to over 30khz, not woofers - ya *need* someone else's woofers to use w/these...
