Wooden speaker brackets from 2×4″ and 2×3″

I wanted to make some speaker brackets for the new (old) mission speakers I acquired for the workshop and having some scrap 2×4″, 2×3″ and MDF, I made up these.

I was inspired by this design from instructables LINK. I choose to amend the design by choosing to use lots of wood glue(!) and mitred some of the edges for aesthetics.

I cut the pieces to size, sanded and fixed with wood screws and lots of wood glue. These will easily support the speakers and I think look good. By cutting the 2×3″ this way it will ensure that there is plenty of room to fix the brackets to the wall either side of the brace. I used two fixings at the top and one fixing at the bottom. This seems to be holding them very securely.

Workshop Sounds – Lepai Amplifier

Lepai/Lvpin Tripath Amplifer

I had been looking for an amplifier for the workshop for a while and read about these small and cheap amplifiers on the DIYAudio forum [link to diy audio posts]. The posts suggested that although cheaply made the amps sound great and are very easy to mod.  So order placed and £19.99 later it arrived. My new version can badged as Lvpin, the new name for Lepai (apparently meaning “dependable product” in Mandarin”). I ordered one without a PSU, I happened to have an external hard drive PSU offering 12v DC 2 Amps output so I hooked that up first to check how this budget amp would fare.

Making Speaker Jumper Cables

Making Jumper Cables for speakers with bi-wire terminals

In Situ

This is a quick upgrade for speakers with bi-wire terminals. My stereo amp only has one speaker stage (eg: one set of speaker terminals) and my speakers have bi wire inputs (eg: 2 sets of terminals), so I replaced the crude metal washers with a short length of speaker cable to bridge the signal. I am sceptical whether it makes much difference as with most things in hi-fi there is a lot of snake oil, but it was quick and very cheap.

Regarding speaker cable I use Vandame Blue 2.5mm (this is studio quality speaker cable and can be sourced quite cheaply online. Personally I do not see any need to spend more, this is very good quality copper cable with a durable jacket to protect the cable).

To make just take an extra piece of cable, remove the outer protective layer to split the red and blue cables. Then strip the insulation on both ends and fix a banana plug to one and leave the other end bare wire. You could attach a spade terminal if desired (the bare copper will tarnish in time).

Then just connect up, not sure if it sounds any better but it does look better.

Using a TV Socket to route speaker cables through a wall

Using a TV Socket to route speaker cables through a wall.

After installing speaker brackets on the wall, I routed cables up to the ceiling and back down the wall to the amplifier. Rather than break the cable and add another join by using speaker wall plates, I choose to keep the cable in one piece and route through a TV socket plate just unscrewing the metal connection plate and pushing the cables through. The face plate was fixed to a standard metal back box (with a gromit to protect the cables).

Metal plate removed – only fixed with two small screws
