Can someone please provide guidance on BIB calcs for two drivers rather than one, and also where best to place second driver.
I want to use two four-inch full range drivers to increase both output and sensitivity, given my DHT amp is good for only 6wpc.
Guess it is best to place the second driver directly opposite the first or can it be sited low on the internal baffle/divider?
Or would I be better off using a larger, higher sensitivity full range driver on its own? Was thinking about two of the Dayton 4-inch RS100s initially.
Any suggestions welcomed.
Cheers
Luigi

Just double the width (volume) of the cabinet for one driver. Mount drivers one on top of another so that their mid point is located where one driver would have been located. This is the general process for fitting two of same drivers into almost any TL.
You can also simply double Vas in the calculator, the calculator will make the volume of the enclosure bigger just like X's approach, but will recalculate to make its proportions in line with the BiB principles. I have made BiBs closely matching the BiB principles and also of varying aspect ratios and it's not like it won't work if it's "off" but if you really want a proper BiB, why not. Driver placement as per X's recommendation.
You might also want to look at the Spawn of Frugelhorn designs for dual driver designs. You can put them both at the front, but also front-rear, front-side etc., they all have pros and cons and one might suit your goal better than the other.
