Does anyone know at what frequency these two models begin to lose pattern control? Or stated differently how low do they go before they begin to beam?
Thank You
As you go lower with any speaker cabinet it will get wider as you go lower-not beamier.
Part of the problem is that most things audio are a "sliding scale" with a grey area.
For example-the rated pattern of the Sh50 is 50 degrees. So at what angle would you consider "loss of control"? 55°-60°-70° something else?
It is not as "cut and dry" as people would like to think it is.
With that being said-and without looking up the data consider this. The SH50 has a narrower pattern and a larger horn.
So because the SM60 has a wider pattern and a smaller horn-the loss of pattern control may be pretty close. For a given horn size-the wider pattern will have control down lower.
So if the choice is between the two boxes-I would let SPL output (SH50 wins), price (SM60F wins), low freq extension (SH50 wins), physical visual obstruction (SM60F wins) be the deciding factors.
