Re: Danley SM 80 vs SM 60F?
As with most things-there are advantages and disadvantages to everything. So here are a few personal comments/thoughts
There are the obvious differences-price-size-coverage pattern etc.
The SM80 gets quite a bit louder than the SM60F. I honestly feel the specs on the SM80 are a bit on the conservative side-and plan on taking a "second look" at power-max output etc.
As far as a "single speaker source" the SM60F goes quite a bit lower than the Sm80 (based on midband sensitivity) and the SM60F has an extended HF response (due to the smaller HF driver).
So to me I would choose the SM60F as more "hifi" or full range. Of course the SM80 was designed to be used with a sub-so the low freq does not go as low.
The Sm80 in in a sealed box-so the LF rolloff is not as steep as a ported box.
If you want to "extend" the LF of the SM80 a bit you can add a boost down around 100hz. This is not an issue untill you get really loud-for a couple of reasons.
Since it is a sealed box, the impedance down low get real high-so very little power is going to the driver (so no problem there). Also the sealed box helps to prevent overexcursion. The cabinet will "tell you" when it has had enough. It will "bark" at you. So simply turn the boost down.
To me-the first question is "how loud" does the speaker need to go?" and go from there.
With enough "subbage" the Sm80 will "do" quite a large crowd. Next Saturday (sept 7th) there will be a free event in the Dallas/ft worth area (not sure where) where the band WAR (low rider etc) will be playing for several thousand people (i think that is the expected turnout). The PA will be a single SM80 per side and a single BC415 per side outside.
If anybody is interested-I will find out where-times etc
PS-if money is an issue-there is a "different version" of the Sm80 that is less money. It is the fully weatherized (heavy duty thermo molded cabinet) OS80. It is larger-but weighs less and goes lower in freq-due to the larger internal volume-so it is more of a "stand alone" cabinet.
