kip - being in the trade, I'd say it's not a bad guess that on a large millwork job, materials may have over-ordered, and you might even find someone willing to help with the cutting.

I think about building OB with W8-1772 or W8-1808 & probably 2x Ciare NDH 15-4s per speaker (something like this PureAudioProject Trio 15 TB Speaker Forget Class A, this rates OMG$$$. Review By Rick Becker).
Still I don't know which W8-1772 or W8-1808 would be better for this project...any ideas?

I've played with both in OB. A great sounding driver in either case.

The 1808 is more intended for this purpose and that's the direction to probably go. The higher Qts will probably help you blend a bit easier to the lower support of the big drivers.

The 1772 would tail off just a bit quicker and mean needing to cross a bit higher. It'd work and sound great though, no doubt.

Using two woofers for augmentation, I highly support. But give thought to how you like your stage height. If you put the 8" driver center, then the stage is down some. Above two big drivers means up some. I tend to like my soundstage to raised a bit, but it's personal what would be more enjoyable. You might differ, depending on what LF drivers you do too.

At least initially, I'd suggest playing with an electronic crossover and biamping. Experiment with the crossover. If inclined, then use what you learn if you want to go with a high level crossover. Depending on your listening level habits and which driver you pick and so forth, you'll probably find yourself crossing somewhere between about 80 to 200hz.

Does anyone have a good crossover design for OB: W8-1772 + Alpha-15 ?

Harsch XO. Most musical and amazing transients.

I've tried different XO combinations, they all seem dull. Then I go back to the Harsch, and it's all good again. That is what I use now for my 15" and W8-1772.

S. Harsch XO

As I understand it's a better method to separate bands.
Given our assumption, what would be the impelmentation?

perceval 19th December 2017 01:49 PM

Two ways to do it.

1- with a mic and REW, measure the speakers and impedance, save frd and zma files. Get XSim, and pick the best place to implement the 4th and 2nd order XOs. Get the values of all the parts and buy those.

2- use a miniDSP HD. Implement the XO curves in there, and play around the 200-400 Hz to find the sweet spot for the XO.

Right now, I have method 2.

Thank you for your response. I'm more interested in a passive XO and I was wondering if someone already did the math and give us all a nice gift
