Goldwood GW-8028 8" Butyl Surround Woofer 8 Ohm
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 ?
They will work, but there is couple of things to keep in mind.The power handling of Bose speakers (200W RMS) is more than twice for what these can handle 130W RMS connected in series. So if you have an amplifier that that can go over 130W RMS you can blow these speakers. The base requires the most power and at low frequencies can peak enough to damage these speakers in even apparently low levels. Barely audible rise in sound requires twice the power. Because these are not very efficient it would be easy to have power level high enough for cause damage for too weak drivers.The other factor is taste how much difference there is in the crossover network optimal point between these and the original. They might sound nice but do they sound real. What somebody might think great might disappoint somebody else.

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.
Although the description indicates they are intended for a sealed enclosure, I installed them as replacements in boxes with port tubes. Since the cone sizes were very similar I didn't alter the port tube length. That was good since the drivers tested for over 15 minutes running a 100Hz square wave at 35W continuous to play with the crossovers, box positioning, checking effects on other drivers in the cabinets, and to test their durability. The VCs stayed reasonably cool and the extra load from the ported box didn't seem to affect compliance or heating. If you push them to the full rated 50W continuous you may be at risk, but for an occasional excursion to 50+W and average of 35 they do just fine for me with 2" x 4½"L tubes sharing 2.8 ft^3 box with a mid and two cone tweeters (all open frame) and boxes lined with glass batts. I had nothing to lose at ten bucks apiece and was pleasantly surprised.

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.

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.

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.

These are a very popular choice for the Bose 301 speakers.
