The standard understanding is that a full range speaker is one capable of producing the audio spectrum from 20Hz to 20kHz. |
Usually referred to single driver speaker and not 2,3 or 4 way speakers |
Your Spendors are considered by many to be full range, but they do miss the bottom octive. True 'full range' have an 'open' bottom end, or no restrictions to how low they will play. There are very few true 'full range' speakers. Even though the term 'monitor' can apply to large multi-driver speakers, it is generally used to describe small box speakers, 'full range' usually refers to floorstanding and other large speakers. Its just a general way to describe the type of speaker. You would list your Spendor S8 speakers as 'full range' here at Audigon. |
Aside from what's mentioned above, Aside from the book shelf and small monitor speakers, almost all the non-single driver speakers today are full range speakers |
S23chang, would you make up your mind, your second statement contradicts the first.
:) |
I hit enter key to fast the first time which I didn't finish my posting. I mean to say the second statement. However, the term becomes more weight when you talk about "single driver" speakers since majority are already full range speakers. |
Name one non-electrostatic/planar/ribbon full range single driver speaker. |
Hey, Ohhwy61:
Would you consider the Avantegarde Solo to be full range (and a single driver) speaker?
(It is kind of a quasi full range single driver speaker. I agree with you that regular dynamic type speakers do not lend themselves to single driver/full range speakers.) |
The AV Solo is a two way system with a separate woofer and tweeter drivers. Besides, it doesn't go deep enough in the bass.
I'm still trying to understand S23chang's comments. |

Some fine single drivers
Western Electric/Altec 756a and 728b
AER drivers
Lowther drivers |
If you would consider coaxial speakers as single driver, then you'll have tons of this type of single driver full range speakers from vintage to modern.
They sound extremely open and effortless except they're big. in cabinet size.
Some fine coaxial speakers
Tannoy : Vintage and modern
Vintage Jensen
Vintage EV

The Loth looks interesting, but I notice it only goes down to 24Hz and there's no +/- qualification on that spec.
I'm not saying that there aren't some very fine single driver cone speakers, but they aren't full range. |
Onhwy61, your ear can't even hear things below 45 hz so I don't know what's your arguement.
AER is 20hz to 21Khz |
S23chang, where did you get that figure from? Sources I know of say 20hz is the human low range limit.
My speakers do -1+1db sub 20hz to beyond 20khz. But then, they are three way. |
Yes, we're physically capable of 20 to 20k yet we don't hear the extremes often unless you have your system is hooked up to a frequency generator.
I'm not sure what note you can hear at 20 hz but I only felt the "wind".
Happy listening |
I can't think of anything that generates a 20Hz note. However, there are plenty of natural phenomena that generate sounds incorporating 20Hz frequency in part. For that matter, much lower frequencies too. |
I can't think of anything that generates a 20Hz note A church organ, for one. Chips... (OK, that's an electronic device). One problem with actually "hearing" a 20Hz note is its length -- ~17,5 m. So, when it's there (rarely) we perceive reflected sound. It's also very difficult to reproduce, requiring tons of amplification power and excursion from the driver(s) |
