A driver "without hornload" still is loaded by the plug of air within the throat. To get rid of it, a terminated tube is used.
Can that explain your weird resonances? If you cannot hear what you...
The slit is a simplification here, it shows the problem in one plane instead of two. There is also an article in Wikipedia about "Acoustic Lobing".
Consider two drivers, each sending soundwaves....
... - this list (available from JBL) says the cone kit C8RE140 goes into the frames E140-8 and K140 as well.

Why don't you start with Thiele alignments 3 and 4 and interpolate between the two? You will need to adjust Qt. For this you need to take into account the crossover inductor's DC resistance of the...
If your Malinois messes up your flat then this may be an indication of underemployment. The Malinois is much more agile and demanding than a normal German Shepherd. If you don't give it employment it...

The formula is simple: S = St * x**2, St = throat area, but you need the horn input impedance.

QB3 Thiele alignment #3 would match if Qt remains unchanged (no passive crossover), and
QB3 Thiele alignment #4 would match if Qt gets changed (passive crossover).
Taking these two alignments as...

You would fix Qt by making it 0.18.
f3 would be 134 Hz,
fb would be 100 Hz,
Vab would be 8.5 ltr.

Look for YouTube Clips named "Exploring wave Motion". There is a sequence of 5 Clips belonging to each other. What you need to understand is the diffraction of water waves and the Huygens principle....
Bldozier, your question is trivial and could be answered by many forum members, but nobody does it. Any idea why?

A loudspeaker test technique is described which...
What kind of measurement gear did you use?

This solution requires two resistors, 1 kOhm or 2 kOhm each. The outputs are added to each other, giving a mono sum signal. The resistors isolate the outputs from each other and are REQUIRED.

Together with L2 and R1 it forms a lossy parallel resonance circuit.

For each speakerbox you buy a transformer which can handle the power fed into the boxes (5 Watts), not the power the boxes...
