2-way soundsystem?

Hello everyone, I'm here to present my project and try to get some answers. I've built four 15" subwoofers (SATH 115 - 99dB 1W 1M, 1000W AES, 41 to 110hz).

Originally I was thinking of making a 3-way system, but now I want to imagine a 2-way system.

The project is to have a sound system that allows us to play a fairly wide range of styles (electro, dubstep, house, techno, disco, funk and more), primarily for DJ sets.

The goal is to achieve a beautiful, natural, detailed, clear, rich, and full sound with good bass extension and a bit of impact.

We're not looking to provide sound for huge spaces or large venues, so the trade-off will likely be the output.

With versatility in mind and to simplify setup, we are considering a 2-way system.

The advantage of our 15" subs is that they perform very well up to 110 Hz. 

The idea goes somewhat against the grain of traditional sound systems that are stacked in 3, 4, or 5-way configurations.

The idea is to use stacks of 3 subs with one tops per stack. The goal is to be able to deploy them depending on the size of the event, with one, two, or 3 stacks.

For these 3 subs, I plan to use a high-performance 3-way.

The absence of a kick bin would deprive me of a powerful impact, but instead I am ready to prioritize a balanced but fairly nervous sound in these frequencies.

What do you think of my reasoning?

Do you believe a minimum of 3-way is necessary, or is 2-way a viable option based on my project?

thank you

Your complete system is going to be 3-way.. subs, mids, highs, there is no way to build a PA system with fewer than 3 bands and achieve true fullrange sound.

Just to add to what others have said, what you're building would normally be described as a "two-box" system.

Single 12" 2-way boxes will still be smaller and easier to move than 15" subs, there is something to be said for system simplicity too... less external wiring. There are 2 ways to build a box like this depending on what you want from it, use a 1" exit CD with a 2khz internal crossover and a mid-bass 12, or use a 1.4" CD to crossover to a more bass oriented 12 at around 1.2khz. The first option gets a bit louder and has good topend extension but may be a little light in the kick region, the second option produces stronger kick and mids(vocal range) but needs some EQ help on the very topend.
