Room size.


I often see folks recommending speakers (or discouraging) certain speakers based on size of the listeners room.  While I have a good idea what would be considered a small room (both length and width no more than 15 ft), I am uncertain on the drawing line between a medium/moderate room and a large room.  Would a 15 x 20 ft be considered medium, and 20 x 25 a large? Disregarding room height for now.

  • DSP can help make larger speakers work in smaller rooms well but can’t really solve the issue with speakers that are too small for a larger room. 
There is no real value to defining room sizes. The point is in general you need larger speakers to deliver flat extended bass in larger rooms.

A good example is Ohm Walsh speakers. https://ohmspeaker.com. You will find every speaker there provides specs on the range of room sizes each is suited for. Too large a speaker in too small of a room will deliver too much bass. Too small a speaker in too large a room not enough. The right amount provides near flat response down to the lowest frequency spec’ed in the right sized room.

Beyond that, room acoustics will always have an effect on bass response producing more at some frequencies and less at others. That’s where setup and possibly room treatments can come in.


The Ohm Walsh very wide dispersion near Omni speaker design is pretty unique though and makes it easier to place the speakers effectively in the room for good results than more directional designs. Also closer to walls and corners which tends to reinforce bass.


The Walsh models large and small all tend to sound similar placed in the right size room.

So how big the speaker need be and how much it will cost is determined primarily by room size which makes choosing the right model per room very easy.

Hope that helps.
