Yes. Here's why.
The reason we have to move subs around is one sub always causes lumpy bass, some areas way louder than others. So you move the sub trying to find the least lumpy location. Which changes constantly depending on the frequency. This happens no matter how great or powerful or expensive a sub you buy.
It also happens when you use more subs. However, and this is a big however, having more subs lets you run each one a lot lower volume. So one of the four is too loud and lumpy at one frequency at one location, way too quiet everywhere else. Big deal. No longer matters. Because you have three more. Each of which is at a different location causing different lumps or modes and not nearly loud enough everywhere else.
But with four all the lumpiness averages out to something quite smooth. Its possible with four to have bass that is both deep and powerful and tight and articulate, as well as smooth. Much more so than you could possibly get with any single sub no matter how good.
Also with just one sub you have just one crossover or EQ. But with four you can adjust each one independently of the others. That's if you run four powered subs. Or if you do like me and some others and run two per amp, or four per amp, whatever. Main thing is any way you do it four beats one even when total cost is held equal.
