2-way design vs. 3-way design means ?


Just curious as to the sound difference between two-way and three-way, obviously a missing element on the two-way of the mid range. I own a three-way Cornwall and I’m thinking of going to one of these heavier and more substantial, build, quality, thicker walled bookshelf speakers.

I guess every speaker sounds different to every different human ear that listens …and it may be difficult to explain in terms of the sound. Obviously, a two-way speaker only has two drivers and possibly different interior components?

Like… what is the difference between a Fritz and a JBL century L 100?

It is easier to have a coherent sound with two drivers. Simpler crossover. More drivers equates to more power handling and louder output.

this ’speakerchoices’ link has cool diagrams that give you clues, you can sort by any column, put in limits ...

number of drivers does not tell you the whole story, here’s

a 2 way with 3 drivers

a 3 way with 5 drivers

the crossover which divides the frequencies, and sends only some frequencies to specific drivers is the determinant regarding 2 way, 3 way,

sometimes a single diaphragm will work with two horns like this

thus a 3 way crossover becomes a 4 way speaker

 

Tekton V12 is a 4 way with 25 drivers

also, you used the word bookshelf, caution, there are very few speakers designed shallow enough to fit a shelf (11-1/2" deep max let’s say), and many have rear vent(s)/port(s) which won’t work in a bookcase.

My Office AR-2ax are 3 way, and true bookcase size, no ports, wire terminals recessed within the 11-1/2 depth, even the rear mounted level controls for the mid and tweeter are recessed. Compact 3 way Bookshelf with 10" woofer. AR-2ax grilles were not designed for easy frequent removal.

 

KLH Model 5’s, re-introduced, compact stand mounted 3 way, also 10" woofer, are 13" deep, too deep for a bookshelf, they have a single rear mounted level control

 

 

JBL L100’s have easily removable grilles and front mounted level controls, a much easier arrangement for adjusting them in place while playing. 12" woofer, too deep for a bookcase

 

A 2 way speaker has a bigger physical demand put upon the 2 drivers of a  tweeter/mid bass. Think about this...those 2 drivers have to make ALL the sounds!

The load is reduced when you divide the frequency and add a speaker to handle just the mid-range and a speaker for just the deep sub bass. The mid-base driver isn't jumping around as much trying to reproduce everything when the load has been greatly reduced by adding a dedicated mid-range and a sub-bass driver.

The same reason why a subwoofer is designed to handle ONLY the deep bass. With the addition of a high pass filter the mid-bass driver can breath easier and has much less movement to the cone surface. Less distortion is the goal.

4 way speaker... is a tweeter/midrange/midbass then add a subwoofer.
