Garage Sub

Message Topic Search Topic Options Post Reply Create New Topic Printable Version Translate Topic

   Hi All,

I want to make a sub that will fit under my bench in my garage workshop.

I have some fixed design points:

The enclosure will be made of 18mm birch ply and needs to have the following external dims:

695 mm width
450mm high
350mm deep

The driver I intend to use is a JBL 15" M252-8 (specs below)

I plan to use a Behringer Ultradrive Pro controller and a Thomann T-Amp S100 which can be configured in bridge mode if required.

I have no particular preference on whether the enclosure is closed or vented - but if vented, then something I can make in the workshop like an oblong 'tube'.

So I'd like some suggestions on the enclosure type/bracing/filling/etc.

Many thanks in advance
Nev
