In all cases, getting more volume from a given number of speakers as compared to a closed box seems to excite them.
In the name of accuracy, "volume" is here used as dB SPL, not size.
Yes, that's pretty much what he did. Reminds me of how "wheatstone bridge" came about. And I find it valid as it's essentially negating any tuning of the enclosure. Same word, different application. Define "scale". I can think of 7 right off.
Is there anything in his book that you can point to and say specifically is incorrect and the term should not apply?
I've no intention of reading his book - but making up a meaningless silly name for something approaching 100 years old doesn't impress me at all 😀
Someone asked earlier "why the use of 1KHz for testing", and you (quite correctly) mentioned that it's the standard frequency to use.
However, you failed to mention that it's also used because you get no bass from baffle-less or small baffled speakers 😛

Open baffle speakers produce bass, you really should read more 🙂

True, but the one shown in the picture without a baffle? And how practical are they for musical instrument reproduction? In a home environment you may get by but in a crowded pub with a heavy handed drummer it might be a little more difficult.

Never seen one yet that does - and that was the reason for larger baffles (and cabinets) in the first place.

"Meaningless" and "silly" from the stand point of staunch refusal to evaluate the usage. Good call. Kind of makes all of "operational definition" required in doing science kind of ridiculous, yes? Like using, say, "induced synchronization", used to describe resonance effects in adjacent strings in a sitar, and applying it to the mechanism thought to develop Hebbian neural assemblies from collections of brain cells, in the gamma EEG range. Don't read my dissertation either, it's obviously bogus.

Tell the numbers they're wrong. Yes, I know, "no intention". I think we know what that means by now.

It's a ported bass cabinet - I fail to see the relevance? - it's not just a speaker mounted on a baffle.

Yet again posts have had to be deleted. This is a final warning. Penalties have already been handed out previously to some of you. Any more personal insults and off topic garbage and its bin time.
how would you construct a box for these fine drivers

but I suppose a guitar driver is not supposed to produce more bass than it does in open back design
and maybe you don't want to carry a 500liter guitar combo 😀

It doesn't really matter, there's not really any low bass from a guitar, so adding a speaker system that has good bass response wouldn't make much difference - while it would reproduce any bass content that was there, is there wasn't any there to reproduce it wouldn't matter.
There's also the concern with a guitar that generally you don't want 'quality', you want a specific 'sound' which may, or may nor, bear any resemblance to how your guitar sounds. Generally for bass guitar you want much better 'quality', and obviously better bass 😀, but probably not high frequencies much at all.
It's keyboards where things are 'best', a keyboard amp/speaker is essentially a HiFi system - you want good bass, good mids, and good highs, all with low distortion.
I've used a keyboard combo occasionally, both for guitar and for bass (and once for both at the same time), it worked perfectly well in all roles - although obviously you don't have the overdriven guitar sound, if that's what you like, but you simply add a pedal between guitar and amp.
My daughter bass combo has a CD input socket, but as there's no tweeter is sounds rubbish playing a CD through, but great with a bass guitar. Adding a cheap and crude piezo tweeter would probably make it quite usable though?.

judging from another thread that was recently posted, I would say not all will aggree with that
if you like a certain kind of powerfull sound, its either a huge setup with multiple drivers, or adding a woofer that has good low end power

You'd said "However, you failed to mention that it's also used because you get no bass from baffle-less or small baffled speakers". The relevance was evidence to the contrary.

OR both. Two towers each with a Trace Elliot 15, two Kustom Turbo 12s and a Peavey compression horn, another pair of towers each with two Peavey Pro 12s, four BOFUs and Peavey compression horn. All designed like closed baffle hifi speakers for accuracy (love that Telecaster twang) as well as power (bass on bottom for floor reflection; powered mixer driven with plenty of headroom). Sometimes you do want a specific sound. For that there's specific combos and f/x. Even then, if you want a lot of volume, you mike the combos into something that's not going to add excessive color of its own. No sense in building them without the ability to serve as bass speakers also. Besides, there's a lot of sounds that come out of a guitar outside the range of E(4) to D(8). Sometimes you want that too.

I think you mis read the poster, at 1Khz there will not be any bass from any speaker.
- E4 ————- 1st———- 329.63Hz
- B3 ————- 2nd——— 246.94 Hz
- G3 ————- 3rd——— 196.00 Hz

- A2 ————- 5th——— 110 Hz
- E2 ————- 6th——— 82.41 Hz
We cross subs at 75hz some people at 100hz
As a sound man we refer to bass less guitars as "his sound is so thin I can't get him in the mix"

fwiw I think Karlson sound pretty good with guitar - here's some of mine - but they may not fit the de-tuned category
I've only run the Commonwealth as a hifi speaker so far - Cannabis Rex sounds real good in a K12

No, it was a speaker (or speakers) mounted in a cabinet, as normal - not just mounted on a baffle board.
Good point. But how much fundamental is there in that low E? I ask because a bass guitar should go down to about 40Hz, but few bass cabs can do 40Hz anywhere near the level of their midrange. We hear the harmonics, not the fundamental.
