## Description

The GRS 8FR-8 full-range 8" speaker is engineered to withstand rigorous commercial use, but will also deliver great results when used in point-source hi-fi applications.

Review: Excellent choice for a replacement/upgrade for small practice guitar amps. - I have a Fender 15G practice amp that was seldom used because it sounded very “tinny”. This speaker really punched up the low frequencies and made it quite useable. Installation was easy, the spade connector lugs were the same size so no soldering and the mount screw locations lined right up. Impedance was correct for this application also. It’s a beefy little speaker with a huge magnet for its size. Mine had taken a hit during shipping and the mount ring was a little bent but I straighten it out with a pair of pliers and it worked just fine. Very happy with how it sounds and I’m glad to put this cool little amp back in service. I do guitar repair and it’s near my work bench in the shop but I have taken it to jam sessions and surprised other players. It has a nice rounded, full tone even with the drive turned up. Well worth the price, I’m happy I took a chance on it.
Review: good value - Replaced 50 year old acoustic suspension full range drivers with these for practically nothing. In a small sealed box (the old Lafayette Criterion 25 ancient but solidly built .75 cubic foot) these sound so much nicer than the original. They're balanced throughout audio frequencies right up to mid treble, where they will drop off. They do lack the ability to provide detailed musicality kind of sound, so for the critical listener, I'd say definitely do not bother with these. But for casual listening, background music, or vocals these are ok. In contrast, Goldwood's 8 inch full range speaker (I have both) has slightly more bass punch audible, but at also less treble production.

**Q: does the speaker have foam or rubber surround?**
A: Hi.  Its foam but its a good quality foam.  Its almost like a hybrid foam of some kind. They are really good
full range speakers for the money.  I used them as replacements in a set of speakers I had that had really 
good cabinets and crossovers.  They will blow you out of the room.  Good handling power also.

### ⭐⭐⭐⭐⭐ Perfect Upgrade for Small Guitar Amplifier
*by R***N on July 25, 2025*

I put one of these in a Fender Mustang LT25 guitar amp. What a difference! The sound is fuller and more balanced. Now, I can turn up the volume and the amp sounds good.
