I have a dumb question but I'm sure someone here will most likely know the answer.
If you had say a polk center, that's a 2 way. That means it has a crossover, right?
Now if you remove the driver (not the tweeter) completely from the crossover and hook it up without the crossover at all. Does that speaker driver now become a full range speaker?
How does that work with full range speakers no crossover.
I know this may sound dumb but I'd really like to know.

Now it will receive all frequencies.
Whether it can reproduce all of them properly or not is a different thing, look at its frequency response curve.
I would think that above some point it starts dropping so it is advantageous to have a Tweeter reproduce that.
Or maybe response drops little, but dispersion worsens, so again it´s good to have a smaller size better dispersion Tweeter do the job.

Thanks for the reply.
Let me give you another example I'm curious about.
I've seen those "atmos" speakers.
They have a 4" speaker, no additional tweeter, no crossover, in a sealed box. Range is listed like 100hz-25khz..... since NO crossover, that's full range, right?
Are those speakers special somehow?
If yes, how?
Is it a physical difference?
Thanks again for the reply

A physical difference, although there may be little difference with inexpensive units. Most woofers simply don't perform well up high. Fullrange speakers aim to reduce the issues.
Thank you for replying,
OK so when a company makes a speaker, it seems it's about the design.
What is it on a speaker, physically speaking, that a manufacturer alters, in order to achieve a different frequency response?
The voice coil windings?
The magnet?
The basket?
Sorry so many questions but I'm just really curious and not very educated about this.

On a fundamental level, lower frequency speakers must be large as they have to move a lot of air and are unable to move (accelerate) fast enough to reproduce high frequencies. Reproducing higher frequencies requires higher acceleration of the cone or dome with considerably less air displacement so consequently they are much smaller. It's a little like a freight train compared with a lightweight racing car! In the middle of these extremes are the so called 'full range' speakers (which they are most definitely not!) which usually manage lower mid to high frequencies fairly well at the expense of the very lowest couple of octaves. Directivity is an important factor which is greatly affected by the size of the speaker.
Also the cone profile and basic design, since most rules of thumb about directivity appear to be based on the assumption of a flat piston of the same area as the cone, which isn't usually the case, most wideband drivers progressively decoupling the outer portions of the cone, some having in effect a mechanical crossover to a direct-bonded central dome (in effect, a mechanical coax). However, the profile comes into play there also, as does the surround design since a steep cone profile will inherently have narrowing polars as frequency increases -especially if coupled to a big roll front suspension.
In fairness, most woofers can't manage the lowest couple of octaves either -that's why subwoofers exist. A lot of wideband units can manage a solid 40Hz or lower for e.g. (albeit this is often at the price of dynamic range), though equivalent-size context is needed for fair comparison. The 'fullrange' term is unfortunate, with 'wideband' being technically more accurate, but like a lot of things it's become entrenched terminology & we're never going to shift it. In the same vein 99.99% of multiways can't be called 'fullrange' either. Speaking for myself, I design & use both types.
