The eWave crossover is usually for 8 ohm woofers. You will have to adjust the values to a 4 ohm woofer. If you mount the wave on top of the boxes .You will keep as much volume as available. When you like them, build the vented box.The cabs are marginal (just a wee bit shallow, so volume is a little under the 1.6 ft^3

Sorry in advance if this question is stupid but- when looking on most of the schematics for the crossover, the HF section (8ohm) and the LF (8ohm) are connected in parallel, so I’m guessing that my amp will see 4 ohm total?
Is that why this project can’t be done with
4 ohm speakers? As most amps won’t handle
2 ohm in total...
BTW - tear 'em up. They never sounded so good..unless you intend to sell them...to finance more Ewaves...yep
I'm no electronics whiz, but I've had some electrical training. Speakers are not just a simple DC circuit with two resistors in parallel. It's an AC circuit with a varying voltage supply and frequency, and the drivers themselves are inductive loads as well as having a DC resistance value.
Lots of two-ways built with "4-ohm" drivers.
I see, but can I actually measure it like I measure a DC circuit? I.e- testing The speaker terminals with a meter and see the actual correct impedance my amp sees under load? It’s probably more complicated then this..
A note about the X-max on the Faital, Faital specifies their X-max as [(winding depth - magnetic gap depth)/2] + (magnetic gap depth/3), so the actual geometric X-max on this driver is only 2mm (winding depth - magnetic gap depth)/2.I've used both the Eminence Beta 8A and Fane Sovereign 225-8 with the 18Sound XD120 as per Zilch's original mini ewave, but was wondering how the Faital Pro 8FE200 would compare - it's about half the price of the 8A and has 95dB sensitivity (8A has 95.1) 4.67mm XMax (8A is 3) but the FS is 80 (8A is 62) . The Fane seems better than both with those measurements (I don't know about the other specs but others here can probably say what's bad about it), so I was wondering how well the 8FE200 worked. Has anyone tried it? I might try the Faital Pro with the P-Audio PHT 408 or 411 to see if the cost of an ewave can be brought down lower still without losing too much in the process. Both those parts cost about the same as a single Beta 8A
Any thoughts or comments on the 8FE200?

Thanks, much.
Now I have to build them
