Hello all,
I currently have a Snell HT setup with 5-LCR500's, 2-SUR500's, 2-SUB550's and and a dual Tempest sealed 0.7 sonosub. After reading an article on Dunlavy in Widescreen Review and his supsequent series of articles, I haven't been able to get him out of my head.
His beliefs are that first order, time aligned, phase correct line source systems are the way to go.
Has anyone cloned his SC-IV A? I think that the IV specs are what I would like to shoot for. Perhaps a litle smaller footprint if possible.
Barring a clone, I guess I would start with Speaker workshop but have been also looking at Soundeasy. Is anyone using either of these? My guess is that I will purchase Soundeasy as it's the only complete solution that I've found that will cover the WMTMW design.
I know I'm biting off a big chunk but the best way to learn, (at least for me), is to dive right in and solve what you can and ask questions on what you can't.
I already have an idea of what I want.
35-20K +/- 1.5dB
flat phase
time aligned
line source
95-100 dB
1st order XO's if possible.
Is there anything I am missing? Am I nuts?
If the goals look close to the Dunlavy SC-IV A's, your right!
Here's the first candidate:
An all Vifa solution
XT25TG30-04 Tweeter
M10MD-39-08 Mid
P21W0-39-08 Woof
WMTMW First order XO at 300 and 3000. Boxes at 0.57 35-20k @ 100 dB looks possible.
Doable? Dumb? The parts individually are ranked high on the snipets page I was sent to. On first glance they seem to play nice.
The only challenge, (beside the XO of course), is that the tweet and mid will have to be fairly close and a stepped cabinet is a must. The question is how to optimize that.
By the way, I read in "Loud Speaker Design Cookbook" that stepped baffles are prefered over slanted baffels. Supposedly they are equivalent on center but NOT off axis. The stepped maintains better alignment.
I haven't done any simulation yet, (that's next weeks assignment), so this all may fall apart but the overlaps seem adequate and the XO's don't seem out of whack.
Thoughts anyone?
Any comments or suggestions would be greatly appreciated, (except building a kit..I'd rather learn by doing!).
TIA,
Phil
