- Page 8 Fascia 1½" MDF (may be double 3/4", laminated) If laminating, use a hard glue such as Titebond. or Solid Hardwood 8 1/4 x 42 2 pieces (4 if using 3/4" MDF)
- Page 9 Plinth and Plinth Detail 3/4" MDF 12 x 13 3/4 4 Pieces (laminated) Spike holes are on the outside corners, 1/2" diameter, 1" deep. Spike inserts are installed with a 10 mm hex drive. Four holes to attach to the bottom of the cabinet take #10 - 2" deck screws.
- Page 10 Fascia Detail Fascia: Material is 1 1/2" MDF, cut 8 1/4 x 42 and rounded over 1" on the front side edges. It is much easier to lay out the driver and screw hole positions before this piece is machined. The woofer screw holes need to be drilled at a slight angle for the screws to bite fully.
- Page 11 Inner Front Detail Cut Outs: Scan-Speak 15W-4530SC: through diameter 5 3/4" , flared on the inside edge of the cabinet. The flare bit should be a quarter round of 3/8" radius. See below for a detailed drawing. D28 through diameter 3 1/2".
- Page 12 Driver Cut Out Close-Up Top View Note that we suggest a "double flare" - the first immediately behind the front edge of the driver, the second as the inner front meets the cabinet. The magnet is quite large and the double flare is required to allow the cone to breath.
- Page 13 Inner Back Detail The cut outs are large enough to allow mounting of the crossover boards.
- Page 14 Lower Back Cover Detail The holes along the edge are sized to accept #6 x 1 5/8" drywall screws. The center holes are 9/32" to accept North Creek Texas Posts. Drill two holes for single wiring or four holes for bi-wiring.

- Page 16 4) Begin the gluing process by laying up the inner back and outer back with North Creek Soft Glue. A few well placed 1" brads will assure the panels will not flow. Also, attach the ladder braces to the side panels with hard glue.
- Page 17 Brace Positions This detail is a side-view of the center of the cabinet. The measurement is taken from the front edge of the cabinet, before the fascia is attached.
- Page 18 Fascia Installation The main cabinet and fascia should be finished separately. The fascia should be filled, primed, and painted prior to attachment to the main cabinet. 1) Coat the rear of the fascia with a thin layer of Aleene's Super Tacky, and lay it face down on top of a heavy plastic bag, on a smooth flat surface just slightly larger than the fascia.
- Page 19 Plinth Installation The plinth should be finished separately. The best results are by rounding, filling, and sanding smooth the top edged, then painting black. 1) Lay the cabinet on its back, resting on several slats of 3/4" material. 2) Position the plinth and drill pilot holes through the bottom of the plinth and into the bottom of the cabinet.
- Page 20 Connecting to the Binding Posts Binding posts fit in the horizontal holes of the rear cover, as follows: on the outside goes the hex-head, ring and stop. On the inside goes the gold-plated star washer and one nut. Tighten to prevent spinning. Next comes the gold-plated crossover connector (described below), followed by a second gold plated nut.
- Page 21 Driver Chamber Stuffing 1) Carefully place the cabinet on its back. Locate the white and blue wires terminated with .110" quick-connects. Extend these wires through the tweeter cut-out. 2) Locate the red and black wires terminated with the .250" quick-connects. Extend the Red through the upper woofer hole and the Black through the lower woofer hole..
- Page 22 North Creek Loudspeaker Kits can be tuned over about an octave by adjusting the length of straws inside the port tube. The following facilitates port tube removal: 1) Add a 2" section of straight tube to the flared port tube assembly. Reserve the rest for later.
- Page 23 Last, adjust the spikes by single turns until the image floats above and behind the speaker positions. When it locks in, you will know. This publication is copyright © 2009 by North Creek Music Systems. Unauthorized duplication is prohibited. All rights reserved.
