Hmmmm. Flat has a funny definition in this case. PA speakers are EQ to flat so they are transparent to the instruments. A cab is part of the instrument and is almost never flat to begin with. To do this kind of EQ requires more control than appears on most preamps. Most of the time people can only do what they can with the knobs available, which is turning down the lows if it’s too boomy, brightening it up with highs or cutting through more with mids.
The fanciest thing to do would be to capture the baseline curve of the cabinet and save it in an analyzer. Then you could subtract that out of your measurement and it would look “flat” when it’s back to your baseline curve.
I keep the little Mooer Radar pedal around for adjustments like this. It has a 5-band fully parametric EQ hidden away. I turn off the cab and amp sim and just use it as EQ because it has a nicer EQ than an EQ pedal. It’s good for notching out a room resonance without destroying the rest of the low end.
Curious of this myself…in theory the AREA of sound (are they 2 8 inch speakers?) would be 16 inches each so 32 inches which should be plenty loud and have a good range.
Saw that they are 5…it could in theory be as loud/louder than a 115 then
It’s a tricky subject but apparently the driver size is not related to low frequency capability. The new drivers also sound better then the old ones. Here is an interview with Phil explaining how it works
I must admit it seems a lot like technical rambling to me and the ongoing stomping noise is really annoying, but I managed to listen to the end and got the important info
When I was a kid, I always thought that “bigger was better” when it came to bass amplifier speakers. I recall a brand (Acoustic I think it was) that boasted an 18" speaker and a horn.
