GRS 4PF-8 4" Paper Cone Foam Surround Woofer
I'm going to use four of these four a 8 ohm load series/parallel. And i'm going to use a piezo tweeter can i use in-line resistor for the tweeter.and let the woofer run full range. Im just asking of a simply way and cheapest way of a crossover. "Thanks"
For your application, it should be sufficient to just use a resistor on the piezo element and let these drivers run full range. However, keep in mind that the capacitance of the piezo element works with the resistor to define an RC high-pass filter, so the actual high-pass frequency of the tweeter will also change with different resistor values. I would start with a 10 ohm and a 20 ohm resistor, then use an L-pad before the tweeter and filter resistor to set the appropriate tweeter level.

Hello! The cutout diameter says 3.75 on the baffle . Can i get buy on a cutout 3 5/8 diameter on this woofer?
Unfortunately no, the smallest cutout this woofer will fit in is 3-3/4".

I'm looking to build a dodec speaker (omnidirectional 12 drivers). Would this speaker be a better choice than the GRS 4AS-4?

My cabinet has a cut out of 4.25 will this fit or should I go with the 5 inch woofer?
This woofer will be too small and the 5" would be too large. You would be better off enlarging the hole to fit the 5" since that is easier to do.

I recently used these in a school project are there any replacements that have more bass? or go lower in frequency?
This depends on how low these are playing. With a 4" driver you can't expect much below 70-80 Hz in a small cabinet. We do offer a few 4" models that will play into the upper 50's in a larger enclosure but they are in the $25-$30 price range.

mounting in micro guitar amp
I have a 5 watt @8 ohm peavy amp .I was hoping to upgrade the speaker Do u think this would improve the sound? this speaker looks beefier than the one in the cabinet and better quality..could u send me mounting diagram or give me the dimension for hole center to center for the mounting screws thanks Toml
This will work well for an application like this although we cannot say whether you will see an improvement in sound or not. The holes are on a 4-1/8" circle.
