GRS 8PF-8 8" Paper Cone Foam Surround Woofer
anyone know what best size (cu ft) the sealed or ported cabinet should be for this item?
anyone know what best size (cu ft) the sealed or ported cabinet should be? also smallest cabinet can bethanks
This speaker will provide the best performance in a sealed alignment, around 1.3ft³ is what I get for "optimum" internal volume. Less than 1ft³ will push the Qtc above 1, which is commonly considered to be a "boomy" enclosure.

Could these work in a 2-way system
I would like to build some budget speakers for my garage and I was wondering if these would work in a woofer/tweeter type system, if so, what would be the x-over point for the tweeter?
These could work as a two way assuming your tweeter can cross over low enough. I cannot recommend a crossover point without knowing which tweeter you plan on using.

What is the diameter of the basket?
I am replacing an 8" woofer in a Boston Acoustics A60 speaker. The diameter of this woofer's frame is 9" and the cutout hole is 8". Will your woofer fit as a drop in replacement? Yours appears to be an inch too small.
Yes this would fall right through the hole. The Bostons are very difficult to replace do to odd frame sizes and shapes, you can either repair the woofers you have or enlarge the opening to ~9" to accommodate a 10" woofer.

What size box?
Okay I have two of these and I am either going to build two boxes (one for each woofer) or one box and put them both in it. One staff member said optimal sealed size is 1.3 cubic feet and another said 0.5 cubic feet per woofer. If I build just one box for them both should it be 1 cubic feet or 2.6? Thanks.
A woofer with a Q as high as this likes one thing, large boxes. I would build the 2.6 for both and call it a day.

How about 2 per 1.77 cu.ft. sealed enclosure?
My woofer airspace is 1.77 cu.ft. Sealed box not including the woofers themselves or "stuffing".I Was considering these or the Dayton classic 8" 295-310 for sealed double woofer duty? Thanks.
The GRS would be better suited for a sealed enclosure. You can expect in room response into the upper 30's/lower 40's relatively easily.

Replacement for Advent Heritage
Hello,I am looking to replace the dual woofers in a pair of Advent Heritages, Can you please tell me if two of these would work in a 1.9 sealed cabinet. If so what should i expect for a low end responce?
These will work well in that airspace, they should play into the lower 40's to upper 30's depending on room placement.
