I am looking for an 8" woofer as a replace for the speaker in my Bose 301 Series ll 8 ohm speaker= rated for 10-75 Watts RMS, Cross over 1.5 kHz and 2.5 kHz, port-ducted enclosure. Would this be a suitable replacement woofer?
These are a very popular choice for the Bose 301 speakers.

What is the optimum internal volume of a cabinet for two of these?
I am intending to build two cabinets with two woofers in each. They are to be used as my surround speakers, and modeled after my Infinity Column II's I bought back in the '70's. They have tens in them and are about a foot square and 40 inches tall. I would like the finished product to be roughly 80% of the Infinity's.
The recommended enclosure for these is about 6 cubic feet sealed. They will work in a smaller volume that is heavily stuffed however. You can expect in room response into the mid-upper 30's.

Retro fit ?
Will these "drop in" my Infinity Reference Three cabs ?
All the dimensions for this Goldwood woofer are listed on our website. Pull the original woofer from the enclosure and measure the cutout size. If it is ~7-1/4" (give or take a sixteenth or so) there should not be any modifications required for this to fit. New screw holes may be necessary.

Will this woofer driver work in Bose 601 Series III ?
There is one review said he or she installed a pair of these woofers in his Bose speakers and they worked great. I wonder if they will work in my Bose 601 Series III speakers ?
You would have to look at their level of experience. Woofers are designed to match certain boxes, have specific impedances and efficiences. Sometimes, a more efficient driver sounds louder and an untrained ear thinks it's better. Whenever changing one speaker in a pair - change both so that they sound alike - or have the "same voice". And do the math. If the impedance and efficiency are not the same as the driver they are replacing the crossover needs modified. Additionally - the driver needs to be a match for the same box size - ported or sealed. Oftentimes, it's best to have your old drivers reconed by the original manufacturer. This is a popular thing to do with classic old speakers like Advent, Dahlquist and Velodyne. I hope this gives you some food for thought. Do some homework and you will find it easier to live with your decision.

suitable for replacing old 5 ohm woofers in 3 way system?
i have worn out 6-1/2 inch woofers in my 3 way speakers, im looking to replace them. they are 5 ohm and 60 watts. would the goldwoods be ok?
Yes, however the product you selected is an 8" woofer and is 8 ohms.I would select one of the many 6 1/2" woofers available and go with a 4 ohm version since that is closer to your original woofer 5 ohm specs. You could an 8 ohm, but if I remember correctly, this could affect your crossover.

Are these woofers suitable for ported cabinets
Are these woofers suitable for ported cabinets?, I wanted to put a set of these in a pair of Infinity SM82 speakers.
This woofer will perform significantly better in a sealed enclosure. It may be acceptable to you in the enclosures you already have, but if it isn't, you could certainly block the ports in whatever fashion you choose. If you'd rather not do that, I've linked a couple of suitable (lower Qts) drivers in the same price range below for your convenience.
