BIB Calculator

There is a thread on the "Full Range" speaker forum that contains a BIB calculator.(Excel)

Thread is Titled:
"Terry Cain's BIB -why does it work and does anyone have those Fostex Craft Handbooks?"

Post Number 5017 from GM has the calculator to download.

Yeah, the spreadsheet dimensions are big. I built my BIBs before GM came up with the formula, back when ScottMoose was calculating them one at a time. The dims I used (stated earlier) are lower volume and tuned lower. Theoretically, this results in a little less excursion control above the tuning frequency, and you can see that the bottom end is shaped a bit different. I had a pretty good sized room back then, and I got so much bass that I had to stuff the vents pretty thoroughly. I would only recommend the spreadsheet dims for someone with a huge room or a real love of bass.

I've got about twelve more minutes (before I need to head to a big band gig), so I'll make this quick. However, I have bunch of enclosure designs for my drivers that should be on my site. Here is a quick overview. I'll try to fill in pics and specs later on.

Betsy: The OB options are fairly straight forward, by herself or with a woofer. You can use her in a sealed box, but I'm not sure why you'd choose to do so. One unique option that came up in discussion is a small aperiodic box. It might be the smallest way to get a Burro speaker into your room, and with it, more sensitivity, dynamics and image size than you normally get in a bookshelf.

BetsyK: Sealed and vented options abound, but here are some more interesting things:

GM posted a 10:1 TQWT that looks great. If you can tolerate a wide cabinet with a decent sized footprint, it promises great performance and a very simple build. Specs to come.

Skinny quasi TQWT/TL: I designed a box for my brother in law after seeing the Zu Essence and liking the size. Mine is about 12x13x44". It is a very easy build with some advantages over a regular BR. I'm listening to a pair right now. I think this cabinet should be very, very popular. My in-laws are thrilled.

MooseBVR: ScottMoose was kind enough to simulate one of his double mouth BVR's for the BetsyK. I'll send you the dims if you want. I plan to build a pair. I meant to this fall, but the Skinny TQWT project got in the way.

BIB: My cabinets stayed in MN when I moved west. However, I can give you the specs I used (skinnier than the calculator produces). They are great fun.

I do plan to do a better, and more complete list than this thread. But, I wanted to get something fun up before folks get home from work!

Thanks! Sorry you think you need to apologize. ;) Hope your traveling went OK; a long time family friend got back from a business trip the other day and now quarantined with just a cold, so far. :(

Yeah, I wish we could edit indefinitely like some forums. I was searching through some of my old posts and found an error in one from years ago, so had to [re]post it.
