But the no free lunch rule applies, the driver cost will usually be higher with multiple drivers, and that's why they don't own the marketplace. As for the lack of large driver 3 ways, that's the result of using 2 way mains with 1 way subs. It's still a 3 way system, contained in more than one box. Since that offers the option to place the low frequency sources and higher frequency sources where each works best, which is almost never within the same footprint, it's by and large a better way to go.

I do believe that several smaller woofers obviously can equal one or two much larger woofers, just a matter of cone size and xmax.
But, I also believe that many smaller woofers, usually can not be as cost effective as one good much larger woofer also. Or, something must be compromised beyond just matching the cone sizes, to keep the price equal.

My first thought was a very large light cone with high efficiency so cone travel is minimized at relative volume levels

As if this is the only parameter that matters...
These folks don't seem to have a clue about the time-domain transient/impulse response, how it is related to the frequency response, and how it changes when the driver is band limited by a low pass crossover.

Originally posted by billfitzmaurice View PostBeing both a speaker designer and bass player, electric and standup, I can say that there's no such thing as 'fast' or 'slow' bass. The main difference in electric versus acoustic is that the tone and timbre of electric comes primarily from the amp and speakers, that of acoustic from the instrument. The size of the body of the acoustic is simply too small to support anything approaching flat response to even the second harmonic, let alone the fundamental. This results in accentuation of the mids and highs compared to electric bass, and that's what those who don't actually know what's happening call 'fast' bass. Test side by side an acoustic and an electric standup bass, the latter in the form of an Ampeg (the instrument, not the amp), and an electric bass. The acoustic bass will sound thin in the lows, prominent in the mids. The Ampeg and electric will sound similar in the lows. The Ampeg will have a different midrange timbre, but a fretless electric will duplicate that.Last edited by Harvylogan; 08-22-2020, 09:54 AM.
