CD is constant directivity – means the top end will have a horn flare that has a specification for the spread it achieves – also means it is a fairly powerful top end (most big rigs use these – ours currently has a pair powered by 2″ throat rigid driver).
The 15’s will likely be fairly decent drivers (if they take a 1500W peak, then they’re likely to be somewhere around 400W RMS).
I assume the boxes will be ported radiators (the 15’s radiate directly – ie you can see the speaker cone from the front), in which case they are likely to be pretty good speakers (most of Wharfedales later radiator designs are based on the same design as the force 9’s)…. They’re full range btw, not mid/tops…
All in all a pretty good set of boom boxes by the sound of it… You should say thank you very much to your bro…:weee:
