I have acquired two 15" Eminence "Delta" speakers that have come from different sources. Now being relatively unfamiliar to this brand and bass speakers in general, I found that there a few different models of Eminence Deltas (e.g. Delta 15-A or Delta 15 Pro etc.) to complicate things, so what I am trying to find out is if these two speakers are significantly different, slightly different or identical. The first "Delta" I have matches the 1st picture (specifically the label), and is in a cab from 1999 marked 300W 8 ohms. This speaker also has "Eminence" written on the dust cover of the speaker. I believe this is the stock speaker from this cab. This speaker looks older. I assume it's the cheapest Delta that eminence has (15A), but the 300W doesn't match the current Delta-15A spec, which is 400W. The second "Delta" I have matches the 2nd picture (" "), and is not the stock speaker from this cab. It does NOT have Eminence written on the dust cover. This one looks newer - i.e. the outer circumference of the speaker cone is fairly glossy. The seller claimed this speaker was "new" when I bought the cab, but who knows.. The cab didn't list a wattage nor do I think it was the stock speaker so I can't give any possible specs. Both are USA made if that means anything. Could anyone shed some light?
