Dayton Audio DA175-8 7" Aluminum Cone Woofer
Given the extended range of this woofer, which Dayton crossover would you recommend with the DC28FT-8 tweeter? I'm going to experiment with this combination in a Realistic Optimus 27 speaker system.
I would recommend using a cross over point of 2 KHz or higher so you can use one like part 260-140.

I have 2 of these and would like to use them for a subwfr application (<30hz desired). ~100 wpc amp 1) How do I determine the best box size/port dimensions/tuning etc? 2) cani use both of them in one enclosure working together? or do 2 separate subs?
Two separate subs are almost always better than one, but it really is application specific. These are able to be tuned relatively low, but will be limited with overall output capability. I would recommend a volume of 1.25 cubic feet per woofer, with a 2" diameter, 6" long port for a tuning frequency of 29 Hz and F3 of 26 Hz. Keep an eye on woofer excursion, these wont take much more than about 20 watts without having problems.

I am considering using a pair of these to replace two 7" drivers in a Yamaha subwoofer model YST-SW120. Crossover adjustable up to 140Hz. The cabinet is 1.6 cu ft. Port is 10" long with 3" diameter. Workable? Suggestions? Thanks!
These will work quite well in that application. It looks like your tuning frequency would be 30 Hz.

I'm considering using this driver as a woofer in a three way setup, but when I model it in winisd with a 2 cubic foot vented box tuned to 26hz it shows that the woofer will exceed Xmax with only 10 watts or less. What can I do about this?
This is a sign that you are probably trying to use an enclosure volume that is too large, or a tuning frequency that is too low. With most woofers, I highly recommend tuning the cabinet as close as possible to the driver's Fs frequency, then adjusting the cabinet size as needed to obtain the flattest response. If you have a driver with high Qts (greater than 0.7), you can often use a larger cabinet and tune below Fs to gain deeper bass, but if the driver is in the typical 0.3 to 0.5 range then this strategy more often results in over-excursion with little input power, just as your simulation is predicting.

Can this woofer be used in car applications? is there a 4ohn version? if so can it be used in a rear deck no enclosure?? Trunk space roughly 12cu/ft
Unfortunately this is only available in 8 ohm but it can be used in a free-air automotive application.

Can you use this woofer for a cheap studio monitor/ even though the efficacy is a little bit low? Not going to play them that loud. near field listing.
Yes these can be used for a nearfield monitor application.
