I have asked some questions about re-coning. Nothing. I guess I am used to this place, which is more heavily trafficked. No worries though. I am suppose to receive the 414's Tuesday, but that is appx. I may take my horn blanks and slap some sides on them and mount up the horns just to give a listen. Why not.

Why not indeed!!!! cant wait to 'hear' you reaction & thoughts

As for Audioheritage its a smaller fan base than here by some margin. Have you spoken to Bill at GPA about recones etc? - super guy. I called him from the UK for a few question I couldn't get answered on AH

Not had a chance, although it will happen soon, as I have some recone work for him as well.

Got the 414's in. Two tested OK. Two have voice coil rub. Seller refunded money for bad two. Dont think I will use them, as the plan was for dual woofers. Dont feel like reconing them either. Will probably just sell them.
Free Air measurements on two that work

37.01 37.01 Fs
.327 .284 Qts
.401 .322 Qes
1.792 2.392 Qms
1.001 1.368 Le

Haven't done the VAS test, as I cant figure a good way. Nickel trick is difficult with vented dsut cap. May try box volume test with 75ltr boxes I have. Dunno if its even worth it.

Got any old toroid inductors? Small hubcaps? Coils of solder, wire?

The main thing is to lower Fs by at least 0.64x. The most accurate way is to raise Fs by 1.56x in a sealed cab, then multiply the cab's net Vb by 1.44x.

What kinda imaging would one expect from side by side woofers? Been looking at the JBL 4345 and 4355 and Just happened to find an Altec version of the JBL 4345, using 416,414,and late model comp driver that is not well knWn. Although I will have all the parts, I have read multiple opinions that say they just dont like the 414 as much as 416 or 515 in the midrange. Having the 416's and 288 on big horn, seems like a waste to use 414. Guess it is question of what you want doing the vocals, horn or woofer. Wednesday should bring numbers on the 416's
