## Description

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

Review: Excellent little woofers, very good quality. - 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.
Review: Great Speaker! - Great speaker. I used this to upgrade a cheap Dollar store speaker and the sound is much improved. Sound is loud and clear, fit perfectly to replace the cheap speaker.

## Questions & Answers

**Q: What is the exact outside dimension of the speaker frame?  I'd like to mount it in an enclosure which allows room for a 3 1/4 inch wide speaker.**
A: The front mounting flange of this speaker is basically square, with the four sides of the square being slightly rounded outward. There are four mounting holes, one in each corner of the mounting flange. The distance across the diagonals of the flange (crossing two opposite corner mounting holes) is 3.75 inches. The distance across the widest middle section of the flange ( intersecting the center of speaker cone) is 3.165 inches. Measurements were taken with a dial caliper and are accurate to 1/1000th (0.001) of an inch.  So, the speaker will just squeeze into your 3.25" mounting space with only 0.085 (about 3/32") of an inch to spare - assuming you are measuring the 3.25" across the width of a square speaker mounting space and not diagonally across the square space. BTW The depth is 1.7".

**Q: Does it comes in pairs or this is just a single speaker ?**
A: It's a single speaker.  If you'd like a pair, you'll have to order two.  Worth the extra effort.  Mine sounds great.

**Q: whats the wattage/rms of this speaker?**
A: Thank you for contacting Parts Express.  To follow are Product Specifications for the item.

**Q: How thick is this speaker**
A: They are good speakers for 10 watts+10 watts in a sead box if this helps any

Great speaker. I used this to upgrade a cheap Dollar store speaker and the sound is much improved. Sound is loud and clear, fit perfectly to replace the cheap speaker.

### ⭐⭐⭐⭐ Lacking on High Freq But Worth the Price
*by A***R on February 14, 2023*

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.
