GRS 15PF-8 15" Paper Cone Foam Surround Woofer
Could I use the GRS PF-8 15" and the visaton WS-17E 6.5 inch mid and the HiVi TN25 fabric dome tweeter in a 3 way speaker crossed at 12db at 2,000 and 4,500 Hz?
Would it sound better if crossed at 800hz? And would an Open baffle design for the woofer but a closed box for the mid and the tweeter sound good? Sorry for all the questions I'm very new to building speakers, thanks

Will these do well in a 2.5 sealed 3-way cabinet? Will be pushing them with a 100w/ch Yamaha stereo receiver.
Yes these will work well in that volume, reaching into the 30's pretty easily. I would recommend heavy fill for the best results.

Looking to replace Cerwin Vega D9 woofers. Would these be a good fit as far as performance?
This would work if you are looking for a very inexpensive replacement, but there are much better performers available. If you want something that will be similar to the originals, take a good amount of power and work well in the cabinets, I would recommend the Dayton Series II 15" woofer instead.http://www.parts-express.com/dayton-audio-st385-8-15-series-ii-woofer--295-130

Can I use this to replace a speaker in a bass cabinet or will it be too hard for the speaker ? The bass amplifier gives 400watts max @ 8ohm.
This will work okay for lower volume levels but you really want to use something like the Eminence Legend CB158, part number 290-497 or even a Dayton 295-034.

Trying to find an inexpensive replacement for Infinity SM 152 15" woofers. These match the wattage capabilities and ohms... but I'm not sure. How would these do? Anyone want to direct me to the appropriate replacement if this is no good?
This woofer will work as long as the port is sealed up. If you want to keep them vented you would be better off with something like the Dayton DC380-8 or ST385-8. The power handling isn't a huge concern.

is this right?!
a 106.00 ft.³ box for a Vented F3 of 14 Hz, how box would that box be in in.?now a real question,what size box to get an F3 of around 25Hz?
This woofer is not intended for a vented box with a Qts of 1.39. This is a perfect IB or OB type woofer where no enclosure is required. Even sealed box is quite large at almost 10 cubic feet and that's still a very high Qtc of 1.3. If you need to hit 25 Hz a large sealed enclosure is about the only way and you will still be severely limited with total output capability. At maximum excursion this models at 95 dB at 25 Hz in a sealed enclosure. That is only 30 watts.
