Frequently asked
A Lowther DIY project centres on a matched pair of Lowther full-range drive units together with the official Lowther cabinet plans for the design you choose. The plans give the full cut sheet, internal geometry and assembly guidance; you source the cabinet material (we recommend high-grade MDF or Baltic birch plywood) and build the enclosure yourself. Recommended drive units for each cabinet can be added directly to your cart once you are signed in.
Yes. Lowther provides official cabinet plans for classic designs including the Acousta 90, Acousta 115/116, Acousta 124, Bicor 200, Accolade 2, Accolade 4 and the Academy. Create a free account on the Build Your Own Lowther page and you can download the PDF plans at no cost, along with recommended drive units for each cabinet.
Each plan lists a recommended and a standard drive unit. As a guide: the Acousta 90 and Bicor 200 suit a single pair of DX3 Concert (or EX3 Concert sealed) units; the Acousta 115/116 pairs well with the PM6A Sinfonia; the Acousta 124 and Academy use four PM7A Sinfonia or DX3/EX3 Concert units. Full-range Lowther drivers are single-driver, crossover-free designs, so the cabinet is matched to the driver rather than the other way around. If you are unsure, our team will help you choose the right units for your amplifier.
Builds range from Beginner (Acousta 90) through Intermediate (Acousta 115/116, 124, Bicor 200, Accolade 2 and 4) to Advanced (Academy). You will need standard woodworking tools, a table saw or track saw for accurate angled cuts, clamps, wood glue for airtight joints, and finishing equipment for veneering or painting. Sealing the cabinet correctly is the single most important step for good sound.
Choose a cabinet design that matches your chosen Lowther drive unit, download the official plans, cut the panels accurately (paying attention to the angled joints), assemble with airtight glued joints, seal the enclosure, then mount the drive unit and finish the cabinet with veneer or a pigmented lacquer. Because Lowther drivers are full-range, there is no crossover to build, the enclosure does the acoustic work.
Not yet. A complete CNC flat pack for the Acousta 115/116 is being prepared and is not on sale. It will be sold with a compatible pair of Lowther drive units, not as a cabinet on its own. The free construction plans remain available. The first release is for the United Kingdom. The detailed assembly guide is separate from those plans and opens after a confirmed kit purchase.
The Academy is an advanced Lowther cabinet design first released in the 1990s. It uses two drive units, with the second mounted in the upper section so sound radiates upward and outward for an unusually large sense of scale. Because of its labyrinth and size it is rated an advanced build, and plans are available to download.
Ja. Lowther stellt offizielle GehĂ€useplĂ€ne fĂŒr klassische Designs wie Acousta 90, Acousta 115/116, Acousta 124, Bicor 200, Accolade 2, Accolade 4 und die Academy bereit.

Jeder Plan nennt ein empfohlenes und ein Standard-Chassis. Als Orientierung: Acousta 90 und Bicor 200 nutzen ein Paar DX3 Concert (oder EX3 Concert geschlossen); die Acousta 115/116 harmoniert mit dem PM6A Sinfonia; Acousta 124 und Academy verwenden vier PM7A Sinfonia oder DX3/EX3 Concert. Lowther-Chassis sind BreitbÀnder ohne Frequenzweiche, daher wird das GehÀuse auf das Chassis abgestimmt. Unser Team hilft Ihnen gern bei der Auswahl passend zu Ihrem VerstÀrker.
