mfk Posted February 1, 2008 Share Posted February 1, 2008 Does anyone have cornwall plans, I'm going to have two spare pair of HII drivers and crossovers very soon, and I'd love to scale down the Cornwall to HII woofer specs ? Ok, please ? Quote Link to comment Share on other sites More sharing options...
Moderators dtel Posted February 2, 2008 Moderators Share Posted February 2, 2008 I don't know if anyone even has the plans, i would think you couldn't just scale them down by size alone ? I would think it would have more to do with the parameters of the driver not just size? Just guessing, I really don't know. Quote Link to comment Share on other sites More sharing options...
jacksonbart Posted February 2, 2008 Share Posted February 2, 2008 Why not just find some Forte or Chorus cabinets? Quote Link to comment Share on other sites More sharing options...
Marvel Posted February 2, 2008 Share Posted February 2, 2008 Here's the two and three port dimensions. The grill is the same in these drawings, which someone else could verify. Bruce Cornwall_Plans.pdf Quote Link to comment Share on other sites More sharing options...
boom3 Posted February 7, 2008 Share Posted February 7, 2008 Are these plans for the Cornwall II with K79 tweeter and flush mounted drivers? TIA! Quote Link to comment Share on other sites More sharing options...
Marvel Posted February 7, 2008 Share Posted February 7, 2008 Boom, That I don't know. I thought the cabinet design was the same until they changed the placement of the woofer on the CIII. (other than the two port/three port difference) Althought, he doesn't show where these are routed for the recessed/front mounted drivers. Those were drawn up by Jim Easley, from dimensions given to him from different members. Haven't seen him around lately to ask. Michael may know if there's a difference in cabinets between the I and II. He is the Cornwall King! [Y] Bruce Quote Link to comment Share on other sites More sharing options...
oldbuckster Posted February 7, 2008 Share Posted February 7, 2008 Are You going to use 2 -12' woofers for the bottom, because 1 won't even put you in the ball park with the Cornwalls 15" ..??????? Cornwall 1's are plywood ....... Cornwall 2's are not ...... Cornwall 1's the backs come off, Cornwall 2's, they don't ...... Quote Link to comment Share on other sites More sharing options...
Groomlakearea51 Posted February 9, 2008 Share Posted February 9, 2008 Are these plans for the Cornwall II with K79 tweeter and flush mounted drivers? TIA! It appears that it's for the C-I's (and early C-II's) because the front mount recess dimension is not shown. Below is a picture of a 2 port C-I (top speaker), and an early C-II (sometimes called "C-1.5") with the 3 port design (bottom speaker), Interestingly, the "C-1.5" still had the removable back and the K-77 tweeter, but the has the fiberglass midrange K-601 horn, and the B-3 crossovers. The port dimensions for the driver flanges are, however, identical. Quote Link to comment Share on other sites More sharing options...
