Best compact enclosure for these Altec Components

[Earl K]

[Mr. Widget]

Just noticed that the Model 19s have the 416B (guess work here), won't the 416 8a be an issue?

Beyond my knowledge and experience. I have only used the Altec HF drivers and horns.

Thanks. Inclined to go in this route too. Just noticed that the Model 19s have the 416B (guess work here), won't the 416 8a be an issue?

Wow! Just Wow! Hope I can have their DIY skills!

What If I just lengthen the Valencia cabinets? Read somewhere that Altec recommended less than 6 cu ft for ducted port.

Clearly you want a Valencia sized enclosure ( since you continue to circle back to this smaller size ) .

So just get on with it;
- Design your boxes, build them & then tune them in place ( I'd suggest that you allow for an external variable tuning system so you can tune to your rooms acoustics ) .
- Port tuning can be effectively done by adjusting duct lengths outside the boxes baffle board .

Here's a link to some enclosure tuning software ;

winISD Pro ( .exe ) download. > Clearly, this software is only for the Windows OS .

Wow! Thanks for this info! If ever it needs re edging and or coning where can I get valid parts?

It seems that for anything ALTEC, you should go there : http://www.greatplainsaudio.com/ ;-)

That's a pretty dumb statement, Earl. What's your grudge?

OP - Download http://www.diysubwoofers.org/design/ported.zip if you want to model a ported cab response. It works whatever your platform.

Nah. Not needed. I believe in natural selection. ;-)

Lee, I stand behind my statement that if an audio DIYer is even half-serious about this hobby > they need to use the WinDoze platform .

This is due to the availability ( and affordability ) of the necessary software needed for passive crossover design ( first & foremost among all the other design disciplines ) .

FWIW ( to this debate ) , I keep ( & maintain ) 3 older PowerPC Macs here > just so that I can keep running some legacy software that only works in OS-9 ( this includes MacSpeakerz, the predecessor to WinSpeakerz> a 1990's era, Box Tuning software ).

I'm also an accomplished HyperCard scriptor from decades back ( and didn't appreciate Apple abandoning support for it when they moved to OSX > that would be the trigger event leading to my epiphany ) .

Yup. Bullseye! Valencia enclosures it is. Thanks for the software tips.
