6-1/2" Poly Cone Midbass Woofer 4 Ohm
Are these woofers candidates for a compound woofer set-up? I kinda feel like 1.5 cf box is too big for a small speaker. Now 0.75 cf in a compound speaker is acceptable. Especially since they are only $5 each. Any thoughts out there?
This should work fine in a compound isobaric setup as long as you aren't looking for huge amounts of output. A pair of these compound loaded will only require 0.5 cubic feet and have an F3 of about 54 Hz.

building a 2way speaker set up using these woofers wired in parallel with this tweeter Part # 279-002 is this going to be okay being that the woofer is 4ohm and the tweeter is 8ohm?
Yes this will work fine, the impedance different will not effect anything. Make sure you have a crossover on the tweeter for protection.

Any point in considering these for open baffle? Fairly high Q, and efficiency. Thinking of stringing up to 4 of these for each channel -- target load being 4 ohms, band passing them around 60Hz, and high passing the full range driver at 200Hz.
These should work well open baffle, especially used in multiples and high passed at 60 Hz.

Sealed or Ported? Looking at building 4 speakers for about a 20'x30' room that will be in the corners of the shop. Would a ported or sealed configuration work better for this? All types of music, some is somewhat bass heavy like hip hop, techno, etc.
These woofers like a sealed enclosure, roughly 0.5 cubic feet each. Porting will give you a bloated bass sound and limit overall power handling.

9 of this speaker in sealed box final load of 4 ohms - shared air space - what should my cubic ft goal be to build to for strong response from 80hz and up ? i hear shared enclosure of multiple woofer reacts diffrently than single ?
You will get the same extension with multiple woofers as you would with one, but your overall sensitivity will go up. The optimal volume for nine of these is almost 7 cubic feet, but if you are only interested in getting to about 80 Hz, you can cut this volume down significantly. Anything between 1.5 and 2 cubic feet will give you extension to 80 Hz, I would recommend heavy fill.

Would these be good replacements for boston acoustics A40 speakers?
