what makes a loudspeaker "full range"? - Click HERE for Original Thread
kneadle
Just so I post in the right place, is there a definition?

Thanks,
Dave

Would generally be a single driver / array of identical drivers reproducing the entire audio band and usually devoid of a crossover network.
Timn8ter
Examples of full-range driver loudspeakers are Lowther, Fostex, Diatone etc. These loudspeakers try to cover the major frequency span of human voice and common musical instruments without a crossover to another driver. Wide-range drivers, those that try to cover most of the frequency span and only rely on another driver at the extremes (i.e. a subwoofer or a supertweeter) can also fit this category. Horn loudspeakers are also considered full-range. Horns can extend full-range drivers, and some horn systems attempt wide-range performance with few drivers.
kneadle
Okay,

So if I build a speaker system based on one driver--even though it's not designed to cover frequencies below 100Hz--that's a full-range loudspeaker, and my completed project will be posted here.

Eh?

Yep, many "full range" projects fall in that category, for example John Krutke's W3-871S projects.

The definition I have used when moving posts to this forum is that the loudspeaker should have been designed not to need a tweeter and should have its fundamental mechanical resonance <100Hz.
kneadle
How about Fs 111Hz?:) I'm building a TL with the TB 881s. Should I post it here or in the general forum?

Thanks,
Dave

Would that eliminate my TQWT with FE207E and supertweeter from being considered "full-range"? Also, the Tangband W3-871S has an Fs of 110Hz which means the John Krutke designs would not meet the qualification either.

Perhaps I shouldn't have been quite as precise, <120Hz is fine. I think you've answered your other point yourself by defining the tweeter as a supertweeter. In the end, the final arbiter is the threadstarter, if you start a thread and feel that the driver is being used as a full range, then that's the end of the matter. Remember, we're only moving threads because there previously wasn't a full range forum...

Thank you for the clarification :)

You're welcome.

Heh heh...you should try being a college prof outlining exam requirements:rolleyes:

I know this is completely off topic and apologize, but I see your from Buffalo kneadle and I'm curious as to which college you work at. I live in Amherst and work at the University of Buffalo. I'm not a college professor though, just a lowly state worker.

Been there, done that. I know exactly what you mean. The more you define things the more people point out exceptions. It's better to have a looser definition - then nobody can pin you to it!

I am a professor of Old Testament at Concordia Seminary at Brock University; that's in St. Catharines Ontario. Small potatoes, but I deal with GRADUATE students who cavil over every stinking detail. And if you've ever looked at the Old Testament/Hebrew scriptures, it's got a lot of details! Augh!

By the way, I just moved here this summer. I really like Buffalo-Niagara. It is a pleasant place to live if I could not continue in my beloved St. Louis.

Oh, and to return us to the regularly scheduled programming of this thread, there's an electronics store about a mile from my house in Riverside: American Electronics (?) I'm heading there today to see what they've got.

Is there a DIY club or something less formal in Buffalo?

I'm also somewhat of a newcomer to the area and haven't met any persons or groups as interested in DIY home audio as I am.

If you ever happen to find any be sure to let me know, I'll do the same.

kneadle
Will do.

kneadle,

I noticed the other day that your location had changed form St Louis to Buffalo. Welcome to the western part of NY. Now if we could only find an audio group/venue in Syracuse we could meet half way.
kneadle
My cup runneth over! I didn't know that I was near Clifton Park. It seems that my move to Buffalo was closer to one pole of the tri-pole DIY universe.

Those poles are: Somewhere west of Toronto, somewhere in Northern Europe, and somewhere in Eastern Australia...

Anyway, I'm being silly. The area is rich with DIYers. I went to that electronics store on Vulcan here in the northwestern corner of the city. Its name is actually Radio Equipment Corporation, and it is AWESOME. The only thing they didn't have was a variac, which is why I went. So I bought a set of alligator clips and promised to come back.

Transistors, capacitors, resistors, shrink tubing--shrink tape--pots, switches, used drivers, kits, and a whole warehouse besides. Oh! It was magnificent!

Wow...I'm flush with excitement. I need to finish up my current full range speaker project and get on with my BrianGT Gainclone with its Nuuklear reactor preamp.

Willikers!

Dave

There's that "willikers" word again:)
Grandma´s_SUB
Are on market full-range drivers,that can be compared with subwoofer?
-if there are, they can be very good solution(price..)

*n00b question..

dean
badman
Most full range drivers have pretty limited bass reproduction. Anything that can do the bottom octave reasonably well, can't do the top 2 or 3 well at all. Hence... multiway systems...
Tweeker
I'd call any speaker covering 8 octaves including human voice full range.

Hey, get creative, make one... i think i counted 4 in this thread alone :)

Its funny the good professor should teach Old Testament as hermeneutics are all about intepritation. What we experience as good sound is open to interpretation as well;)

Are you talking about me? I just did a thing at Brock University on the Simpsons as an Old Testament allegory, if you really want to see it my way. :)
