2 1/2 way speaker?


Can anyone explain  the difference between a 2 1/2 way speaker and a 3 way speaker? Both have two xover points. I just purchased a Spendor that is a 2 1/2 way and the xovers are 900 HZ and 3.2 HZ.
Thanks much!

Think of a crossover point as actually being 2 filters:

1 - High Pass
2 - Low pass

So, in a traditional 3 way there are 2 crossover points but 4 filters. Got it?
With a 2.5 way, there is a missing filter. The driver that would otherwise be the midrange misses a low pass filter. That is, you have two drivers playing all the bass.


The benefits are better efficiency than a 3-way using the same woofer size, in the smallest possible footprint for that woofer.

They are very good choices for modest to medium sized listening rooms.


Eric nice explanation and Yogi which Spendor? I am a big Spendor fan myself so congrats!
Thanks Eric.
jond, thanks, the Spendor is the A5r. I have owned Spendors before and I would like to give these a try.
Normally, the two drivers are the same, but they cover different frequency ranges, as explained above, i.e. one of the two is rolled off earlier than the other.  So it's not a true 3-way, and not a true 2-way.  Hence....
