Made with 18mm Baltic birch, cut on a CNC machine - this is for the WB4 with the Sounderlink DQ40TZF-02 wideband driver. This driver is a nominal 4” paper cone, with a 4 ohm rating, and has a whizzer cone and a copper colored aluminum phase plug. These are sold in pairs - price is for a pair.
It includes all the wood parts to build a pair cabinets, and a PDF assembly manual. (It does not include drivers, baffle step filter parts, or any other hardware. You will need the WB4 Mass Loaded Transmission Line Speaker Build Manual to complete the speakers.)
Flat packs will be cut after ordering, and shipped via UPS. Shipping cost will be calculated for your zip code. Sales and shipping are available ONLY in the USA.
PLEASE NOTE - when you place an order for a flat pack, we will cut it as quickly as possible, and do a preliminary dry fitting, and then box it and ship it. If we need to order more Baltic birch, when you order, that will increase the time until we can ship it - so the lead time may be 2-4 weeks for your flat pack to be shipped.
Also, as we have patient customers who have been waiting for flat packs to be available - we will prioritize shipping to them. This may mean a longer lead time, until the initial demand is met.
Thank you for your patience & understanding!

The first photo is on the CNC cut flat pack after the 12mm x 12mm chamfered edges are cut. The following 3 photos of the pair of cabinets side by side show the CNC cut flat pack assembled - without the chamfered edges cut. The 6mm edges are the rabbeted corner joints of the 18mm Baltic birch panels.
