Have your UREIs (which are essentially an Altec 604 with improved
horn)

And with higher current handling capability & MUCH better crossovers. OTOH,
there was something to be said about the original (silver painted) 604 cabinet.
Not as much low end, less boomy, sweet.


Inasmuch as "point sourcing" goes, you can't do much
better than these,

Yes, but I always had a bit of a problem with the degree to which the UREI horn
flare masked the 15". I felt there was some disturbance in the low end, but
it's been so long since I mixed on them I can't remember at what frequencies.
