Mark,

Dumb question - you previous woof 6s were pretty flexible application wise, and from the comments of satisfied users, solid performers too - any specific design goals prompted you to change them?

Regards,
Zia

Thanks

Mark...You just ok'd a SPAM attack on Tony...LOL

Hi Zia,
Its a good question. The competition in the cheap woof market is very strong. The first woof No.6 did quite well (from my memory around 2500 units) but to make it pay, we needed more sales.

Take a look at Boris's (et al.) wish list and note the "90dB". We've shortened the coil on this driver, changed to 6-ohm to lighten the winding in an effort to reduce Mms and drive up SPL. My hope is these efforts will make the new driver more attractive to Diyers.

Cheers
Mark.

if there were any differences, the version marketed via Bob as EL166 was just fine as it was, and FWIW I think squeezing too hard for higher sensitivity at this size / intended bandwidth could destroy what it does so well ( i.e. Bang for Buck) , and the longer the production life over which you can amortize your tooling / parts moulding etc costs, the better for all us

Hi Chris,
I'm with you on this but quite a number of lower cost 6.5" paper coned woofs claim +88dB. Any woof I make has to compete in this wider market to survive. Many Diy audio folks love higher SPL and buy accordingly (hence all the hours of effort with the 12P).

Bandwidth wise, I'm hoping to get time next week to process the frequency and impedance, you'll likely be happy with the results.

Cheers
Mark.

My understanding is that there were quite a few more tweeters made, and there are still lots of them in distribution. It is the woofer that is needed.

since this is your forum, you're able to control the "warmer" replies (mine included if need be), but I think the operative word in above post is "claim"

is there an emoticon for "can o' worms" or "$hit-disturber"? damwell should be


I just so happen to have the spec sheets for Alpair10.2 (which is quite growing on me, but still not yet as favorite as the 7.3 or EL70) and a 12" (which I've not yet heard) by maker famous for their OEM/DIY/musical instrument models - very interesting . Aside from the 12's approx 10dB difference in nominal power band sensitivity, 4dB rise in the 600-6K range, and 10times power handling which one would be surprised not to find in this type of driver, what's most interesting in closer inspection of the TSP and FR graph is the only approx 3 dB difference from 300Hz down; with the Alpair's built in BSC, almost identical Xmax, and 10Hz lower Fs extending the little guy's "anechoic" F10 almost a full octave lower than the 12"

horses for courses of course
