Goldwood GW-10PC-8 10" Heavy Duty Woofer 8 Ohm
I have a homemade subwoofer enclosure and i wanted to put this speaker in this 2.1 cubic ft. box to replace the older one. I was wondering if i should add a port to the enclosure? Size? or if it would sound better just being a sealed enclosure?
I would recommend adding a 3" diameter, 5" long port to this enclosure. This would tune the box to 35 Hz.

The 8 ohm version of this speaker has a much wider freq. range than the 4 ohm, yet the print catalog says they are the same...??
The wider freq. range is important for my application.
We can only list what the manufacture provides us although after looking at the frequency response graphs provided by Goldwood, they both are virtually identicle. The graph shows that both woofers only play up to about 1k before a rise in the response up to about 2k and a steep roll off after that. I will have our product tech verify the proper stated frequency response with Goldwood and have the print updated online.4 ohm:http://www.parts-express.com/pedocs/more-info/290-322-goldwood-gw-10pc-4-more-info.pdf8 ohm:http://www.parts-express.com/pedocs/more-info/290-324-goldwood-gw-10pc-8-more-info.pdf

Max vs. RMS wattage
I was wondering if the Max wattage is the wattage it can handle for a short amount of time without becoming damaged? So, i can't give it a constant 270 Watts without it becoming damaged? The RMS is the wattage it can handle continuously, right?
Max wattage is essentially an irrelevent number. The RMS wattage is the most you want to play through a speaker at any given time. Also, the wattage a speaker can mechanically handle changes with frequency. I tell people every day that the power ratings on speakers are the most overrated numbers simply because you never know exactly how much power a speaker is being ed in the first place.

how would you cross this over? running it with goldwood 8" woofer
Both would be woofers in the bass module part of speakergodlwood 8" heavy duty + this 10" incher
First, you do not want two different sized woofers sharing the same airspace in the cabinet. If one will be used as a dedicated midrange and will have its own airspace, the crossover point depends on the specific application.

Will a 60W amp be enough to drive these?
Yes 60 watts will be enough to drive these to over excursion without much of an issue.
