Perhaps this thread can show other sizes drivers, the exercise is to show how to integrate large speakers into something with a degree of elegance, these two I believe both use 10" drivers, but a single 15" could in theory be used to occupy the same space.

I think 10" again, but huge bass horn enclosures.

I think the question needs to be asked - are you actually trying to accomplish something, or are you just soliciting pictures of cool speakers?

12" or 15" or larger speakers are ...well... large. Which is precisely why modern tower speakers use smaller drivers, because they are ... small.

Many designers have attempted to cheat and create speakers with a small face, but a large bass driver by creating Side-Firing Low Bass Woofers. But with a forward facing woofer, there is no way around a large front face.

In short - You can't want to haul cargo freight in a VW Beetle.

However, if you apply some ingenuity, you can get a combination of slim speakers, that would also accommodate some larger low bass drivers. Here is a design I'm planning -

I wasn't planning to go quite as large as 15", but the principle still applies.

But in the end, no matter how you slice it or dice it, but woofers mean big cabinets. Even with Side-Firing, the cabinet volume necessary for a 15" or larger woofer is BIG.

Likely the only realistic solution is going to be a bookshelf or tower cabinet for the mid-bass, mid-range, tweeter, and another cabinet for the Low-Bass or Sub-Bass driver.

Overview of F10 Home Theater_HiVi,Inc

Overview of X3F/X3SUB Home Theater_HiVi,Inc

Overview of F2.2F Home Theater_HiVi,Inc


But in this day and age, I question whether a 15" bass driver is really necessary, at least not for Home Stereo or Home Cinema, and at least not in the main speaker.

Specification of F1.1A_HiVi,Inc.

Certainly FOUR 10" bass drivers would move enough air for any one.

So, you goal and purpose very much influence our responses. If you are simply considering a stereo speaker system with a 15" bass drivers simply to try out a design with a 15" bass driver, then it is pretty straight forward as long as you can live with the cabinet size.

However, if you have other goals, then you need to make them clear.
