CONSTRUCTOR SERIES

2-Way Trapezoidal 15" Reflex Enclosure Project

T

he ‘Fane Constructor Series’ of documents is intended to provide guidance in the construction of loudspeaker cabinets specifically optimised for Fane components. Each enclosure has been designed and rigorously tested to ensure optimum performance from the recommended components. The construction guide and panel cuttinglists

provide sufficient information to enable any moderately experienced woodworker to build their own enclosures. Alternatively, Fane Acoustics will be pleased to recommend approved cabinet manufacturers. Designs for other enclosures and drive unit combinations are available on request.

Hints and Tips
Choice of timber
We recommend multi-layer 18mm Birch plywood as the best material to withstand the rigours of intensive ‘life on the road’ or likely exposure to damp conditions. Alternatively, 18mm Medium Density Fibreboard (MDF) offers good acoustic properties with the advantage of being less expensive ( although heavier ), and may be used where the cabinet willbe permanently installed in a dry environment. Both materials accept any type of paint finish extremely well.

Drive unit fixing
The drive unit should be front mounted to the baffle using T-nuts and fixing bolts, and is supplied with a length of self adhesive foam sealing strip which should be fitted around the front edge of the speaker cut-outs to guarantee airtight conditions.

Loudspeakerprotection
The exposed front of all speaker drive units is of course vulnerable to damage, necessitating some means of protection which must be robust but acoustically transparent. Cloth/foam type grilles are feasible for fixed cabinets, but a metal mesh grille is certainly the preferred and superior option. It is recommended that a foam gasket material is used between the wooden cabinet and themetal grille to prevent any unwanted resonances.

Construction technique
All joints should be totally airtight, liberally glued with PVA adhesive and screwed at 200mm (8”) centres with 4.2mm or 4.8mm (No.8 or No.10) x 50 mm (2”) self-tapping screws. The bracing panels are designed to ensure rigidity of construction, making the cabinet as free as possible from panel resonances caused by the...
