Choosing a speaker for an application can sometimes be tricky. Taking into account the idea of aesthetic, program material, necessary volume for the application, and mounting location are just a few of the considerations that need to be made. When dealing with the slim line array speaker (like the TOA SR-H or TOA SR-S) you are dealing with a speaker that is commonly going to be mounted lower to the audience listening plane. One of the issues that can arise in this kind of application is the absorption of sound by all the bodies in the listening plane causing a large variance in dB SPL from the front to the rear of the venue. So, in wanting to keep with the aesthetic of the slim line array speakers how do you accommodate for that longer throw? That's when it's time to stack the speakers.

The TOA SR-H3L and SR-H2L are both speaker options that can be stacked, increasing the size of the array, frequency response, Sound Pressure Level, and throw distance. However, it is important to note that the SR-H3S and SR-H2S cannot be used in a stacked array. (See the SPL response.)

The TOA SR-S4L can be stacked on top of either a second SR-S4L or an SR-S4S. In addition to all the same advantages as stacking the SR-H series speakers, this would also provide an increased vertical dispersion when stacking an SR-S4L on top of an SR-S4S. (See the SPL response.)
