Comments about Eminence Alpha-8MRA 8" Pro Audio Speaker:

The original speaker was a 75W 4ohm Eminence. The company didn't have this anymore so this was close enough. You can solder an 8 ohm resister across the terminals to achieve the 4 ohms if u want.. I found the 4 ohm difference not troubling at all. If you decide to add the parallel resistor, make sure the wattage on the 8 ohm resistor is adequate for the task.

good speaker great price

Comments about Eminence Alpha-8MRA 8" Pro Audio Speaker:

so i just got this little 8" speaker in today to replace the stock (Chinese made) Celestion Super 8 in my Kustom Tube 12A combo... first thing i noticed was a much tighter low end, which i prefer, and an almost wah-like quality to the midrange, not necessarily a bad thing, think Brian May and you have the general idea, kind of Vox-like. Eminence USA made, so quality is very good, I have acquired several of their speakers, and am never disappointed. this one was a bit of a surprise with the mid-heavy tone, but like I said, its not bad, just different, im guessing the open backed version of this speaker might cut down on the midrange... overall though, a very even tone, tight lows with prominent mids, great for cutting through a mix, and for the price, definitely a great buy
