A strange question, I know, and I'm probably going to get mixed opinions, but...
I have a pair of Altec 604-Cs with shredded cones (imagine that!), so I am going to recone them, of course. But once I've done that I plan on experimenting with differing horns, since they're simply mounted by two screws. 3D printing ought to make for easily made horns for experimentation...
But the 604 series use the funny felt "diaphragm" to seal out dust, as a dust cap would do on a regular woofer.
Is dust infiltration really such a big deal? I see so many "full range" drivers designed for the SET Tube-amp Crowd for use in rear-horn or TL enclosures that have a "phase plug" on the center pole, preventing the use of a dust cap. They seem to run open without dust protection.
I can guess it might depend on how dusty the environment is. Maybe how much iron dust is in the air. Don't laugh; as cars' brake discs wear, they throw off iron dust!
Any thoughts from the Altec gang?
