GRS 8PR-8 8" Poly Cone Rubber Surround Woofer
Would this woofer be a good replacement for a pioneer model CS 44 ?
This might be a good option. The main thing to check would be the actual driver dimensions. There is some variation on speaker frames so the outside diameter and cutout is important

Port size for 12x16x12 box tuned for 50hz
I will be making some 2-way home theator speakers, I would like to tune the 12x16x12 boxes for around 50Hz. Also, Would a pvc pipe work for a port? I have used them in the past with DIY speakers, and have had no trouble, thanks!
A 2" diameter, 2" long port is required to tune those enclosures to 50 Hz. Yes PVC pipe will work perfectly as port tubes.

Will these work well as replacements for dual 8's in a 1.5 cu.ft box?
I have a vintage Jennings Research cabinet that uses 2-8"ers in a sealed box. Crossed over at 2500hz and 500hz respectively.I see from the specs that PE recommends smaller box and since there's 2 drivers can essentially double the box size? Which would be about 1.6 cuft. But, Qts looks like they should want bigger box?
These will work fine for that application. The box size we have listed is a high Q alignment because the optimally flat volume is quite large.

Would this be a good replacement woofer for the Boston Acoustics A-60 speakers? I have a pair with tweeters but no woofers.
I'd first like to know if the A-60's have crossovers. Also, what are the specs of the tweeters you have?

I put this in a .88 cubic ft sealed box and it sounds great, but the bass isn't deep enough for me. Could adding a passive radiator help. I don't know much about them. Or is the box to small for this woofer.
I would personally not recommend using a PR with this woofer. It does not model well and you will have much smoother response leaving it in a sealed enclosure.

I need an exact outside diameter measurement on at least the first 4 speakers on the 8 inch page. Or at least these. Every one is stated as 8" exactly, and I know that this can't be true. Every speaker's OSD is different. I need to know because I need to find a cheap replacement for my old realistic's that drop right in to a 8 & 1/2 inch cutout that's routered and recessed flush with the front baffle. I don't have a router, so they have to fit exact.Thanks.
The standard cutout is 7-3/4", the recessed routed flange is most likely 1//2" - 3/4" wide to allow flush mounting. Any of these speakers will fit without modification.
