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.
Review: Behaves well in a traditional folded horn bookshelf enclosure - 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.

**Q: Is the price for one speaker or two**
A: Onr

**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.

### ⭐⭐⭐⭐⭐ Excellent choice for a replacement/upgrade for small practice guitar amps.
*by E***N on March 18, 2023*

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.
