GRS8FR-8 Full-Range 8" Speaker Pioneer Type B20FU20-51FW

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.

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.

I had a pair of 30-year-old shelf speakers (AR18) that were in the back of my closet that needed new drivers and these fit perfectly sound great! I did try to find "Originals" but couldn't, so I went with these instead and was very pleased with the end result.

I bought two of these for my Klipsch kg3.5’s……there a two way speaker and lacked midrange……what a difference it made…..now I have a great midrange as music lives in the midrange frequencies……..I did lose a little bass, but I added my Klipsch R12D sub to the mix…….such great tone in such an inexpensive speaker…….i might order two more and build open dipole speakers with a set………I did keep my stock Klipsch 8” subs for re-sale, if I ever decide to sell them……but definitely a good buy for the price…..only downfall is the way they ship them……I had to straighten one of the baskets from being bent in shipping….but not hard to do…..these were exact replacements for my old ones…so no re screwing them……all the holes lined up……the frequency on these is a flat line across the board…from 32hz to up around 2500hz……but only because their crossed over……but without crossovers, they are flat across all frequencies…..

The media could not be loaded. Video doesn't sound great because phone mics are dogwater. These are good speakers from 100hz, maybe to 10k. Need tweeter for all around good sound in a mid/high application. Don't try to make a lot of bass with them, just use a subwoofer. I'm going to try to seal the back next. I've also recorded audio using them as a microphone.... not quite as good at that, but surprisingly good actuallyI drive them off a 100W/ch amp but they get plenty loud from a headphone amplifier at 3-4 volts very loud. Even line level from my USB interface is audible and useable.

Got a very good sound from this speaker in a traditional 11" x 22" x 11" (~2,666 cubic inch -- 1.5 cubic feet) 3/4" plywood folded horn enclosure with a cheesy 2 pole crossover (definitely not a sharp cutoff) starting at around 2KHz. No mid-range speaker. Used a plastic sealed back horn tweeter initially. Changed to a cast metal sealed back horn tweeter later, but it really made no difference that I could hear.Bass was strong enough to justify reinforcing the long side of the enclosure back and sides with a 1"x 3" oak bar solidly glued and tacked down the middle (the front is reinforced by the shelf that makes the enclosure a folded horn -- or at least "slot loaded").Used a few bats of upholstery padding as acoustical dampening to get rid of booming. The nice thing about upholstery batting is that it stays where you put it and doesn't interfere with the speaker over time.In the end, driving this this speaker/enclosure pair with an amplifier that delivers an honest 15 watts RMS blows the socks off plastic enclosures when it comes to full range music like jazz & classical. It won't go to the chest thumping bass of club music -- the speaker is only 8" and there's no replacement for speaker diameter when it comes to shaking the room.All in all, this little speaker has the makings of a great sounding listening system.

It is just a mid range speaker. You get what you pay for.

I ordered this as a replacement speaker for an old radio. I only needed one. After ordering it, I saw a couple of places in the description that made it sound like it was going to be a pair of speakers. It's not. It's a single speaker. And a pretty nice one too. It was packed like others have said--a plastic bag inside a cardboard box, but mine arrived in perfect shape. At any rate, it's a really decent speaker for the price, but ignore anything in the description that says "two pieces" or anything like that. I'm happy.
