Not sure where you've obtained any of this misinformation, but it's entirely false. SI was a custom version of the Eminence Beta-15CXA coax, built by Eminence to Darrel's specs.
It's called OEM. Eminence does that a lot.
Regardless, point is.. Beta 15CX probably wouldn't be the most suitable for this app, and neither would an SI.

Not sure what you're really looking for, Alex, but you could do a lot worse than the rigs Victor Wooten and Donald Dunn use. 4x10's plus a single 15. Should give you the dispersion you want with enough air for most gigs. If you only want to use a 15 plus a single 10 (why?) then go for a JBL compression driver instead (or something of that ilk).
Not sure why you'd want to try using a single 15" unless you're at home - in which case, just sit in front of the speaker...
With or without dome question
Hi,
this post might be off, but don't want to open a new topic. I tried Fountek FW168 (6.5" midbass) as a full ranger, and with a dome (27tbfc/g). It can be used as a full ranger (tried it without appropriate filter), but off axis performance was bad. With a dome it works very well (used 2KHz crossover).
Other 6.5" (full range) drivers have the same off axis performance?

There are several things to consider here in this situation if you are wanting to do a bass guitar amp. D'Oronzon sound uses a modified version of our TD15M for their bass guitar cabinets which many have told us is the best sounding bass cabinet they have ever heard.
This single 15 has many advantages. With 6mm Xmax and lots of motor strength, it can play as loud and low as most 18" bass drivers. It will fully cover down to the Low B at 31hz. With the tiny inductance it is flat to over 4KHz and by 10KHz is only about 5dB down in response. This allows it to be played fullrange without the need for any piezo tweeter or cheap horn that most bass cabinets add for the top end response. It sounds extremely smooth and natural since the cone has really no cone breakup. The single 15 will beam up at higher frequencies. This is a benefit, not a drawback. It allows for a mic to be placed right in the center to pick up the response all the way to 10KHz or higher. The beaming also greatly eliminates feedback from the other mics on stage if the cabinet has to be placed behind the musicians. The response also rolls off smoothly in all directions and as you have only a single driver there are no massive cancellations to worry about.
The traditional 4x10 cabinets have much worse midrange and high end response than the single 15". With the 4 10" drivers you have a center to center distance of approximately 11" between the left to right and top to bottom drivers and then 15.5" center to center diagonally. As you move left to right or up and down you'll see huge nulls created by the interaction between drivers.
