GRS 3FR-4 Full Range 3" Speaker Driver 4 Ohm

This is an odd review to write since it's kinda' out of my expertise area, but here goes:Bought this to replace a blown out full range in a Bluetooth speaker. Is just a tad bigger than the original 3" full range but still fit the enclosure and mounting holes with no modification needed.Sounds as good as the original, if not better, and a LOT cheaper than replacing the whole speaker unit.Don't know what else to say, I can't go all audiophile for this one, it's just a fun DIY way to prolong the life of and maybe improve the sound of aging speaker units.Update 4/24/19: Yes 2.5 YEARS after my original review and the little speaker is still going strong despite spending it's life outside, covered and in the shade but you can't hide from 115*F degree ambient temperatures in the summer, plus our dust storms that get grit everywhere.Rock on cheap little speaker!!!UPDATE 8/7/2020: Yes it still works!!! After almost 4 years in an outdoor Bluetooth speaker, in the AZ desert, the little speaker is still working!UPDATED UPDATE 1/10/2022: The little speaker that could is STILL WORKING! However the plastic outer housing of the speaker unit is no longer weather tight and has gotten brittle, the battery no longer holds a charge and must be plugged in to work, BUT this replacement speaker itself is soldiering on MORE THAN 5 YEARS LATER even though the rest of the speaker is coming apart. May have to take it out when the housing finally comes apart and mount it on a plaque or something

Very Good, will buy again. Loud, crisp sound

Like others of said, I’m not sure the speakers are full range. They are loud and sound good, however, the speakers that I was replacing were much more crisp and hit the high frequencies better. However, these speakers are very well-built, with a heavy magnet and a high quality cone. Two of these and a tweeter sounds great for small applications.

great replacement full range speaker

I had a woofer go bad in a small speaker, these fit perfectly. Larger magnetic and appear to be better quality. This one is a little bass-ier, probably because there is no whizzer cone. Sound quality is very good though and do is the volume ( good efficiency for a small speaker). Bought last summer and still working great. I am very happy, will probably buy another and just swap out the one in the other speaker too.

Update: Cost 50% more now. Trump's gift to you, I assume. Have to drop two stars.I bought two to use as "testers" in a pair of folded Voigt boxes I recently built. I'm amazed at how good these 3" speakers sound in this application. I'll be getting some more expensive drivers to replace them at some time (that's always been the plan), but I am very satisfied for now with how well these inexpensive little guys sound. When I do replace them with higher end drivers, I'll likely pick up six more and build an array system speaker set. At $10 a pop, they are an experimenter's dream.

I bought these speakers for my first build your own speaker project. Picked these because they were cheap and every website I found them on had great reviews for them. I have to agree, these little guys are definitely worth it. I am very pleased with these speakers.

Purchased this 3" speaker as replacement upgrades to a Bugani Bluetooth speaker. Cheap Bugani sounded better, these GRS speakers sound more like tweeters tha a full range.
