Advanced Speaker Design adheres to the scientific method- the formation of hypotheses, testing, measurement, statistical analysis and evaluation of replicatable results. It's a discipline perfected over the decades by dedicated, highly-educated men with pencil moustaches in white coats. Experts.
I am not one of those people. That's probably why amateurs such as I should never be permitted to handle sophisticated electronic apparatus such as electrical tape. I am concerned that the guerilla group P.E.T.A. (People for the Ethical Treatment of Acoustics) are monitoring the 'experiments'
that have been recently conducted here in Fukuoka.
Econo-Wave Random Application #3 (in a series of...)
Introducing the
Wave Of Mutilation (Pixies, 1989) with special scenic shot.
Yamaha NS-1000M - EWG - Kpm crossover.
Maybe this is hard to believe, but it sounded like a NS-1000M with the Econo-WG stuck on top.
Woofer connected to X/O LF better than run full-range.
Random, ambiguous adjectives: articulate, fast, detailed, smooth.
Will try swapping around C100 values in the Zobel to tune mids... hey, it worked with the last project!... really need the woofer measurements, I suppose. I'm curious what would happen if I whacked the Yamaha woofers on the large, ported cabs:scratch2:
Quite satisfied with the HPM-100 version, but I feel the Yamaha project is the next worth pursuing, if only to appease the Econowave Gods.
Mounted the waveguides in boxes. Read (somewhere) of a bloke applying modelling clay to the exterior of a waveguide/horn thingy to address what he described as 'ringing'. My wife watched me conducting this high-tech procedure, and couldn't resist comparing me with a pre-schooler. My wife thinks she is funny. She is also no longer in my will. I can't say for certain whether the clay made for improvement, however my notes tell me last night was the first time that I have preferred the attenuator at the '0' position, rather than in a minus increment.
I see this as two projects, Econowave-Yamaha and a less defined 811B buildup.

One problem is the cutout for the original Bozak woof was 12 1/4 inches, and doesn't work with standard sized replacements. I'll probably attempt to fit a new baffle board over the entire face of the original one.
