in BiB?

[gychang]

According to PE, this can be used with mid/bass at 2-4K Hz, can this be used in BiB with addition of the tweeter? (plan to xover at 2K).

any thoughts?

Hi,

the driver looks problematic around 1.5KHz. The tweeter does not do 2kHz.

Tangband W5-704D easier crossover, and can be crossed high to a small dome.
(around 3.5KHz to 4khz)

There's no reason not to make a two-way bib. I belive that 'Zilla has asked why he hasn't seen any yet.

There are plenty of good drivers out there that aren't "fullrange".

What were the critria for chosing this driver? Any specific design goals?

I was looking at something along the same lines but using this woofer here . It's nearly fullrange so you can bring in the tweeter up high and out of the "telephone band".

Has anyone here made a multi-way Bib?

edit: I got ninja'd on the driver by sreten.

I posted this at the BIB thread before:

I did cross the tweeter ~9kHz to a 5" 'nearly' full range driver.

The drivers I used are not available in the US anymore afaik.

Doh' I remember those now. They had those cool k-slots on them. Have you done anything to them since?

Similar to fred76's units. Very pleased with these. 1 in each of the four corners of the listening/theater room.

They would make a nice sized BIB. Not real sure about the kevlar cone, some do not like the sound. But, for the price, could be worth a try. As for the little 1.5k spike, dare I say it, a crossover. If so, definetely a little larger tweeter. This may all depend on what the intended use is though.

The driver gurley123 suggested looks very good, have been eyeballng it also. The qts is a bit more in the range for a horn.

Doesn't really matter as a tweeter is going to be used anyway. The cab. will likely just be a bit larger.

Go on Zaphs and look at the specs and graphs of some of the lower end Seas midwoofers. They've got some great flat responses with nice, polite rolloffs up top, ideal for for running fullrange with supertweeters, and many make for only moderately sized BiB cabinets and should be able to handle fairly low tunings, to boot. I'm interested in this sort of arrangement myself, and have run pretty much everything 6" and under through the BiB spreadsheet, just to see, and some of the results were really promising. You're just looking for a reasonable combination of low Qts, low Vas and low Fs (and low $$ in my case, too).

any suggestions on the demensions?, or shall I plug them in on the BIB calculator using the mid/bass driver specs...
