I have had one of the new Eminence Commonwealth (8 ohm) speakers in my 1 x 12 extension cabinet for 2 weeks now, (about 30 hours of playing time on the speaker) and I must admit that I am VERY impressed with this speaker. I did, as one other earlier review stated, notice a slight bit of high end "sizzle" when I first started playing through this speaker, but that quickly dissapeared after about 10 hours of use. This speaker is quite big and HEAVY (21 lbs) and with a 225 watt power rating you do have to feed it a bit of "juice" to get it going, (I certainly wouldn't recommend it for bedroom volumes) but once it gets cookin' this is one spectacular sounding speaker. Warm, FAT, HUGE sounding, well balanced, and extremely detailed seem to come to mind here, and if I didn't know this speaker had an aluminum dome by looking at it, I certainly wouldn't know it did by listening to it. I can get this speaker to be bright, but I have yet to get it to be harsh. Prior to the Commonwealth I was using the Tonespotters and then the Red White and Blues, and in comparison both those speakers sound rather small in stature. I do have one of the new EVM12L Classic 200 wat speakers arriving next week, but it will have to be one spectacular sounding speaker to knock the Commonwealth out of the cabinet it now occupies.
