Hey all. I was looking into some speakers and started noticing some speakers advertise crossover networks in specifications and others did not. Thinking of this, I wondered if a set I currently own did not have crossovers. I pulled the phono plates (these are Peavey PVi10 speakers I got within the last two years) and there is nothing in there, just wires going directly to tweeter and woofer.
My questions.
A) Is this common? I haven't purchased speakers (other than these Peavey's) for a long time, but have never seen without crossovers.
B) Isn't this 'bad'? It would not be filtering (both full range signals) nor distributing power (woofer should get more).
C) Should I add a crossover, or in this scenario is it designed this way by MFR to power as it should?
D) If the cab says 8 ohms, what would the components be? 8 or 16?

bit weird. The woofer could be run without crossover, but tweeter hardly. Are you sure there is no crossover components mounted close to the speakers?

If the tweeter is a piezoelectric type, it does not require a crossover.

I assume it's not a compression horn, though it is not specified. Wouldn't there still be a distribution of power issue without a crossover? Or could the 10" be so low power, they match power use closely enough?
A piezo tweeter provides its own natural crossover. Its impedance is so high at low frequencies that it consumes no power at those frequencies.
So basically is the tweeter irrelevant to the power consumption and ohm rating of the cab?

As a matter of interest, piezos can be used with a crossover to good advantage:

Would something like this improve these speakers? Or am I just wasting money?

You would be wasting your money.

Is that because the 10" woofer is really intended as a full range and wouldn't benefit from isolated frequencies?
The 10" is run direct, but will have a natural roll-off at high frequencies due to its increasing inductive reactance.
