I am interested on doing a 2 way system with top driver w8-1772 in a 1.5 cu ft sealed enclosure and the Beyma 10g40 in a ported enclosure.
enclosure width is not determined yet. maybe 12-14 in.
Based on the sensitivities of each w8-1772 and the 10g40 about 95db would this work?
No filter on the w8-1772 and a 2nd order on the 10g40.
Should i also throw the 10g40 on the rear of the enclosure?
I downloaded Edge and played around with that... but i am looking to use the 10g40 as compensation.
Thanks for any help!

It looks good / flat for a speaker of this type. I like the 30 degree curves.
Rule of thumb = a woofer that's +3dB relative to the top driver. I'd opt for a little more. It might depend on personal taste and how far off axis you listen.Based on the sensitivities of each w8-1772 and the 10g40 about 95db would this work?
Maybe consider this cheap Eminence 15" - see this model of the deltalite II (with 2nd order crossover), which looks about right for your project.

No. Based on Rutcho's sealed box graph for the w8-1772, you'll have to run the helper woofer fairly high.Should i also throw the 10g40 on the rear of the enclosure?
My suggestion is to use Edge and also a bit of trial and error with the baffle size + shape. e.g. make a (small) test box for the w8-1772 and experiment by tacking on wings made from scrap wood or cardboard. You should be able to find a layout that flattens out the 800Hz bump by about 3dB.I downloaded Edge and played around with that... but i am looking to use the 10g40 as compensation.
Running both together at around 95dB cutting the woofer at the step frequency sounds OK assuming you can manage the extra lower frequency energy, ie it's fine anechoically to go that way. It's all in the details.to use the 10g40 as compensation.
