Maybe if I use different word it will be clearer. Starting from the high end of a multiway system; Highs, Mids, Bass, SUB Bass.

As Ryan said, they're just names. If the low end of your 3 way system goes below 40Hz, you may not need subs, so why worry?

I understand and that is what I have been thinking.

Or for the related drivers tweeter, squawker, woofer and subwoofer, respectively.

Ok Thanks for all the input. I have two pairs of JBL Scoops (Old Vintage) that I run as Bass and that is what I have always called them, Bass cabinets not subs. Their transducers are capable of going down into Sub Range. I sometimes run a two way system or three way system but none of the other cabinets have woofers in them just Tweeter Cabinet, Midrange Cabinet and the Scoops. Again thanks for the insight.
What do you consider "the sub range"?  Sub what?  As in below what?

Back in the days of the scoops (yes I used to run singles and doubles), there were bass mid and high cabinets.

Nothing went that low-as most music of the time did not go that low either.

If you REALLY want to be accurate-you need to discuss FREQUENCY-not the "name" of a device.

And in the end-what does it matter?  It is just an opinion and different people are going to refer to it differently-so unless you have more information (such as the ACTUAL FREQ REsPOnSE AS IT RELATES TO THE SENSITIVITY!!!!!), it is a meaningless conversation with all the answers being right and wrong at the same time-just the perspective changing.

I have a Pair of the JBL 2205 J (16ohms) and a Pair of the JBL 2225 J (16ohms) all in single Scoops. Depending on what I am using as tops and the configuration, two or three way I use Crossover points of 100hz to 200hz.  When running them as two pairs I run them in Parallel.  When running them as a Pair, I either Sum them and run an amp in bridged mode or just run them in stereo pair.  I call the Scoops Bass speakers not Subs.

Here are the specs for the 2205 J http://www.jblpro.com/pub/obsolete/2205hj.pdf

Hi Canute,

Considering your bass speakers roll off (and unload) at 55 Hz, you may want to consider adding subwoofers for the octave below that contained in post vinyl pop music ;^).

IMHO, if it's down more than 3dB at 30Hz with respect to 100Hz, with more than double the distortion of 100Hz, it's not a subwoofer.  There aren't many subwoofers, and none that can be afforded by real people ;-(

If it is in a separate cabinet, it is a sub woofer. If you have a horn and a speaker below then it is a woofer.

Read the rules, fix your display name.

Thank you for your cooperation.

Oh, sorry, I see Mac already issued a warning about the name policy and you chose to ignore it.

You get a 30 day timeout.
