Perusing Parts Express
So I’m looking over P.E.’s Buyout/Clearance section, just seeing what’s available and what could actually be considered worthwhile. (Natch, who doesn’t like to get the most bang for their buck?) In their Midrange / Midbass / Full Range drivers section, I sorted by price, low to high, and Show All. Skipping over the really tiny TV buyouts, I get to the somewhat larger units, ~4″ or so. I check out a few for their specs, mostly they are Meh.
Then I get to this: 4″ Treated Paper Cone Woofer 16 Ohm, PN 299-320
I have my good old QuickBasic programs running and it seems to be a decent enough unit for Bass-Reflex. Acoustic Suspension, Nah. But, starting at $5.80 it would be okay for seriously low budget build or “give-aways”.
Okay, file that one away for consideration.
On that same (4 across line) is the RESTOCKED Wavecor WF146WA01 5-3/4″ Paper Cone Mid-Woofer 4 Ohm, PN 88-298-1164 ( you can see the driver parameters on PN 298-1164). A much more solid unit, but at almost 10x’s the price ($50) and new ($69). I ran the same programs for this driver and it is good for both Bass-Reflex and Acoustic Suspension, although I’d go with different designs than supplied on the product page.
The top row is the $5.80 no-name with Acoustic Suspension followed by Bass-Reflex while the bottom row is the WaveCor, same order as above. I kept all possible differences the same (box Q for A.S. and port size for B.R.) Now this is just using FO, VAS, and QTS. I could do a Bandpass box or Transmission Line too, but I think those would be better suited to different drivers.
So who else goes through the “catalogs” and does similar research?
