How good must full-rangers get to replace 2-ways?

Talking about bass and trade-offs, I'd just like to bring in to this the question of what bass notes we actually need. Since I'm a bass player, this is home territory for me!

Four string basses go down to E which is 42hz. In jazz you'd typically play a lot more Fs which is 44hz. In orchestral music most of it falls within the same four string bass range, though music is written down to C 33hz (that's an octave below the lowest cello note for unison passages) and 5 string basses cover this, as they do in rock and funk. Organ music and the bottom note of the piano go down lower, and wonderful as organ music is it's still a minority taste.

So I'd make a case for bass going down to 42hz being fine for most musical needs. And this being the case I, for one, am absolutely not going to sacrifice any midrange for anything lower. Lets even say that you are happy with bass down to G. That's 49 hz. You compromise only 3 semitones. Let's even say you can tolerate bass down to A, that's 55hz. You compromise 5 semitones.

I would like to hear 42hz, maybe a little quieter but still very audible. Below that, as the film goes, "frankly I don't give a damn".

You will have to be going much lower to reproduce a 42 hz note .......
 
Dear Bob,

I experienced the same thing at Toppsy's house, Frugel Horn Mk III's one pair with Fostex FE126 sounded as you say "well ...... small". And quite frankly didn't sound that much better than my little Needles.

Hey Presto!! We brought in the other pair with [dunno whether I should mention this again!] Mark Audio CHP-70's and the sound broadened out and filled the room and then as they do the speakers disappeared, leaving only the music.

A wonderful reminder of my first real audio experience at a friends house, Lowthers in Acousta cabinets!! :)

Good to hear it, Zilla!

I was close to building a Beta12 LTA complete with putty, phase plug and super tweeter, then I realized my garage is made out of metal. :eek: Went with the vertical line array (12W/48T) to see if it does overwhelm reflections or not. At the end of the day, I'm in an acoustic beer can. :(

Does the Beta 12 NEED a lot of space or is 1 meter distance good enough? How close can the Eminence 12" FR be used in the near field? I could use a Beta12 LTA with super tweeter on a "bridge" like the Hammers. Make it about 50cm wide, 90cm tall and very shallow so it fits behind my computer desk? BIB won't fit and my wife would bury me in the box.
 
FWIW (not much maybe), stereophile mag has reviews of two full range speaker systems this month. (well one is not a full review, but in one of the regular columns)

not DIY of course, but interesting to see what the other side of the market is doing ;)

If you skim past the fluff of the article as I do there are some interesting comments. one is a small "2+2" from Audience. and the other is a new Rethm model with built in subs.

haven't had a chance to look much at the measurements yet...

This tells the tale ....................:)
 
^ Recently they reviewed Totem Dream Catchers. The reviewer said:

"Of all the speakers I've reviewed in the last 28 years, I have never enjoyed music more through anything else, regardless of price."

Wow, impressive! Then look at the measurements and John Atkinson says:

"I was disappointed by its measured performance."

Can full rangers replace 2-ways??? Well, they can replace this 2-way.

Looking forward to seeing those Full range reviews regardless of their funny descriptions of "great" sound.
 
As far as I'm concerned the measurements are the only part of steriophile worth reading. The rest is a bunch of ignorant music lovers describing their emotional responses to what they see and hear. Luckily I can usually translate audiophiliac babel into scientific theory but it's much easier to just read the measurements.

"If it measures good and sounds bad, it's bad. If it sounds good and measures bad you measured the wrong thing." -Somebody very intelligent.

I really think Stereophile is good humor on top of being educational. Otherwise, I would have never found out that the verisimilitude of my silver cables was highly dependant on the direction into which they where applied. Unfortunately, I had burned them in without regard to directivity, so I had to throw them out. Sibilance, texture and tonality, areas in which these cables could have shone, had become irrepairably impaired, with an irrevocal loss of transparency and physical dimensionality.

The good thing is that you can now pick up a 12 issue E-subscription for less than 10 $.

I found this especially interesting in the Rethm review:"We [Sam Tellig and Jacob George of Rethm] chatted about full range drivers... [Jacob]Even when a full range drive-unit isn't doing everything right, he suggested, it's doing some things so right that the sound becomes compulsively, rivetingly listenable."

I think that really sums it up.

What makes them ignorant brsanko ..?

The fact that most of them have no clue as to how electronics actually work, or as to what is causeing the distortion that is making that speaker sound "fat" or "thin" in the midbass, or the fact that the bass sounds "slow" on this recording because of the resonances in the cabinet from the bass speaker. Then they insist on using terms like "Brittel sounding" or "liquid" which are simply learned catch phrases that most likely mean something completely different to every reviewer. I used to love to read stereophile magazine and could just imaging how the speakers sounded from the discriptions the authors used. Then I started experimenting with building speakers myself and using various amplifiers and realized that if these guys really had "golden ears" they would know what it was that was giving a product a certain "sound" and then they would know how to fix it. Because what they all want you to believe an audio component either sounds right or it sounds wrong and if it sounds wrong the problem is usually pretty easy to diagnose and then fix. The problem that makes for so many differentr opinions out there is that most people like it when it sounds wrong and they do all sorts of things to get that certain distortion or compression that they love. Which is fine.
