In Reply to: RE: anyone experienced with MCM's $24 compression driver ? posted by tomservo on January 19, 2017 at 05:00:23
the K-horn filter seemed toned right-on , took down things a few dB - but the speaker still sounded horrible - i think part is the resonance of my room walls. Good thing I'm playing with mono - maybe the MCM ID knockoff mid would be smooth enough for a 350-400 xover.
I am always looking for good/cheap/interesting alternative drivers :-/
In terms of cheap, good ol' Pyle has a panoply of cheap compression drivers.
In terms of good... well... who knows?
FWIW, I do have one pair of the cheap-ish Pyle PDB512 2/3 bolt treble drivers (I do believe I mentioned this before; I am too lazy to go back & check!).
Pyle PDB512 at PE
They seemed OK when I tried them on 511B horns -- I haven't tried them on better sounding horns, but I DO intend to!
These were about the same price as the ones Freddyi's asking about, and might (?) be a little more civilized and might (???) be a little more extended in response in both directions -- maybe (????) even flatter in response than what in essence is a purpose-built PA driver.
Just a thought :-)
PS I do agree that unit-to-unit variability is a pretty common 'feature' of the cheap drivers (not just compression drivers)!
PPS One thing I can say about the above-mentioned Pyle ( ahem ) drivers from my relatively short tests -- the sensitivity quoted in their specs seems to be, shall we say, a tad optimistic.
Yes, a wee tad.
all the best,
some years back, I bought 4 - Pyle compression drivers, two 1" two of whatever was larger, none worked - got burnt. Threw them out. That was probably just bad luck but tainted my view.
That's an understatement, actually.
The two I bought were (are) OK -- just sayin'.
all the best,
It would have been OK if I had purchased from Partsexpress, who has good service on duds = expensive lesson - I'm not sure if PE had the larger format driver at the time. I think I bought those larger exit drivers for some never used Altec 1.4" format horns.
