Need Onken information

abarson · 8th September 2008, 09:29 PM

Greetings!
I'm new to speaker building, and I've decided to build a 12" extension speaker for my bass guitar as a first project. I just got an Eminence Deltalite 2512 for a bargain price, so that's my start.

I was initially planning on going with B&C's Sub12 design, but I just stumbled across the "Petite Onken" design and realized that this appears to be what the Genz-Benz Neox cab design is based on. This was one of the cabs that I liked, but couldn't afford. So now I have a bunch of questions:

1. Are Onken designs easy enough for a beginner?
2. Are Onken designs good for musical instrument cabinets?
3. Are Onken designs "full range"?
4. Would the Petite Onken meet my needs or should I look elsewhere? Where?
5. Is there some way to model an Onken design in WinISD?

Your patience and knowledge is much appreciated!

I've built the mFonknen but for audio not a guitar amp. Here's a link with some info, don't know if it helps but it certainly has options!

You'll probably want to search Google pretty hard to see if anyone has gone down the road you'd like to travel.

Good luck.

Try this:http://web.archive.org/web/*/http://...ONKEN_CALC.xls

It's a link to the Old Onken Calculator I found using the Internet Wayback Machine.

If you have a spreadsheet, it should open in it, I use Open office, but it's an Excel file. Open Office fired it right up.

Hope this helps.
