Thank you for your ongoing support of Ohm Walsh speakers, and congratulations on your new 4.3000 upgrade
kit! Your upgraded speakers will have higher treble for more defined, “airy” details on music. Reproduction of
voices will sound more natural. The bass will be tighter and tuned lower.
Your kit contains:
(2) new Walsh 3000 drivers on new mounting boards
(2) new input boards, equipped with gold binding posts and internal hookup wires
(2) vent adapters (foam-insulated black plastic tubes)
(2) new internal damping pads (wool batts)
Gather the following tools:
•
A hammer and chisel or wood block
•
A drill with a Phillips screwdriver attachment and 1/8” drill bit
Assembly:
1. Disconnect your Walsh 4 speakers from your system.
2. Remove the grills and drivers (four black knobs and one plastic wire connector)
3. Set the cabinet on its side on top of a soft surface like a tablecloth or blanket (to protect the finish). You will
be able to do the work on the floor, but it will be easier if you can work on an elevated surface like a table.
4. Slide the vent adapter into the vent opening until it sits flush to the bottom of the cabinet.
5. Using a hammer and chisel or wood block, knock out the old input board from the inside. Make sure to get all
the pieces when you pull it out of the cabinet; anything loose inside your cabinet may rattle.
6. Run the wire on the back of the new input board from the outside of the cabinet, through the hole where the
old input board used to be, all the way up to the top of the cabinet.
7. Line up the new mounting board around the hole you just made, and screw it down with the provided wood
screws. (It may be helpful to mark the position where these screws will be driven into the cabinet, and pre-
drill pilot holes with your 1/8” bit.)
