Holes for the manifolds
The stud layout happened to suit the openings perfectly. This old house has no noggins, so no structural members were cut
Gluing of manifolds
It's hard to beat the old "rope tightened with a stick" technique. It's been around for a long long time...
A pair of "six packs"
One of the Venom drivers
There seems to be something else in the box....What is it about cats and boxes anyway?...
These look so good it's a shame to hide them in a wall
Test fit - back
Still be able to see the back though....
Test fit - front
Once the grille cloth is on, it should be quite neat
In the past, I've used normal screws to hold drivers. As long as they're not done up too tight, they work just fine.
I'm going to try these roofing screws which are about to be sprayed black. Twelve drivers certainly need a lot of screws!
The final product turned out very close to this sketchup design
Ready to install
One of the two manifolds
There's a fair bit of weight ....
Manifold 33 kg
Total 85 kg
Shelf brace, driver opening rollover and top edge bracing
The Venom driver comes with a removable rubber gasket that slips over the driver lip. Adding washers to the mounting screws allows a firm mount without overly crushing the gasket. This shot was taken after the initial tightening with a cordless drill which had a safe setting on the clutch.
A cardboard template was made up to mark where to drill the screw holes. The small rebate makes locating the template easier, as well as holding the driver roughly inplace during install.
Silicone was used to seal and isolate the manifold from the house framing. A spatula was used to get a smooth finish. Sealing two manifolds on both sides of the wall took 10 tubes.
Grille neatly hides all the innards. Standing off from the wall by 5mm allows movement without coupling to the wall
Two manifolds open right where the main speakers will be located
Rear view of installation
Rear view of manifold is quite acceptable
The gasket was given a final tweak by hand with a socket set. This added about 1/2 turn to the screws which resulted in a small amount of deformation of the gasket
The plasma TV finally arrived meaning the room was rearranged. The mains now sit next to the manifolds
The rearranged room with the grilles fitted to the IB's
