In the extremely extensive category of 'daft things I've done' there is, in the same building, an expensive Summer toy and an entertainment system to help with making hours on the Winter turbo trainer somewhat more palatable.
The entertainment system features 5 old skool Linn speakers, the main left and right pair being a near mint set of Cherry finish Linn Ninkas. They're wasted in their current surroundings and deserve to be in someone's living or listening room. So I've been looking around for something less smart for sometime. A chance visit to a Linn forum member's house gave me some Ninka scale inspiration, in addition to some Katans I've seen pictures of, belonging to another forum member I know. So a plan was hatched to create something unique.
To paint a pair of Ninkas, it's easiest to start with Maple or Cherry finishes, as they don't have any physical grain like the other finishes. But it would seem wrong to paint the cherry speakers I have, they're just too good for that. Something else to consider is value - Cherry Ninkas sell for much higher prices than Maple. So the best starting point would be a slightly scruffy Maple pair. Finding stuff before it reaches the lottery of ebay is usually good, on the fee occasions it happens.
So the donor pair were secured, then the finish had to be decided. Furniture and kitchen refinishers in my area generally fall into one of, or both of these camps: they won't touch speakers or they only do a standard palette of colours. Fortunately I found a company that would take on the speakers and would paint from a sample. Given that the speakers I've been inspired by were both red, and that they would be occupying the same space as the red Summer toy, then the choice was made to match the car - in this case, Austin Rover Targa Red.
|The starting point - rear of Maple Ninkas|
|Starting point - front of Maple Ninkas|
|Removing the drivers - all the bolts are the same size Torx fitting. I remove the tweeter first as its the most delicate|
|The top mid-bass driver and tweeter removed - note the mid-bass driver magnet looks massive - largely due to the magnetic shielding - a reminder of the days of CRT televisions|
|Each component was wrapped up for protection - here a mid-bass driver|
|All the drivers out - time to dig down to the crossover|
|Roll of fibre removed from behind the upper mid-bass driver - just to show the internal construction - there was no need to remove this upper roll|
|One roll removed immediately behind the lower mid-bass driver, then another roll below that and you can see the crossover|
|Working from the back of the cabinet, its necessary to remove all the collars from the connections. First, the white plastic blanking plugs are removed|
|Choice of collar removing and refitting tools. The round handled one is the nicer to look at, the plain steel bar is much the stronger|
|The removal tool slots into each side of the collar|
|All the collars removed - under the collars are the 2 plates that allow easy reconfiguration between various passive and active connection options|
|Both the connection plates removed. In the centre there is a single crossheaded screw that holds the crossover in place. This was removed to allow this area to be masked off for painting|
|Here's the connector side of the crossover|
|Once the crossover was released from the back panel, it was held in place inside the cabinet with a cable tie to stop it rattling around in the cab|
|Whilst the speaker was on its back, time to take off the badge. The edge of the wood was protected by 2 layers of insulation tape|
The 4 M5 allen bolts that hold on the (optional upgrade) polymer bases. These four bolts are removed to remove the bases. I took the M8 spikes out of the four corners first - its a bit safer that way.
|After removing the polymer bases I added 4x M5 bolts and locknuts so that the speaker could still be stood on its base without damaging the cabinet finish|
|Now with all the fibre re-inserted cardboard circles were cut to cover the driver holes. Masking tape hold them in place|
|Before prep and after prep - time to work on speaker 2|
|Both cabs prepped|
|Box full of carefully wrapped and padded bits|
|Sample colour panel - provided by the auto bodyshop the last time the Sunbeam was in for body work|
Just after I'd finished prepping the Ninkas, at set of 5 Maple Katans popped up on ebay. It seems a set of 5 is not a popular number of speakers, meaning their cost per speaker was a good bit lower that it would be when just buying a pair. One pair went to a new home, the single speaker will be good for spares and the other pair joined the Ninkas in being prepped for painting. The Katans will replace a black pair I have which get used from time to time (for example, the Scalford Hifi Show 2015).
|Maple Katan ready for stripping|
|Drivers out - their connections need to be unsoldered - I use a 40 watt iron. Unsoldering or soldering wires to the tweeter needs great care as its possible to melt the plastic around the connection tabs|
|Inside view of the Katan crossover|
|Inside view of the Katan's rear port - before existing the port the soundwaves have to get through the felt on each side of this box and then through 90 degrees into the port itsself (just visible as a black tube below the box)|
|Katan connection panel with plastic blanking plugs and all collars removed|
|Both connection panels removed - the connectors and crossover are held in place by a single screw, just like the Ninkas|
|Katan crossover removed from the back panel|
|Connection side of the Katan crossover|
|Badge removed and cardboard masking discs in place|
|Masked connection panel|
|I don't know where this particular Katan has spent its life - perhaps on its back on the top of a cabinet or something? Its only dust, lots of it, so cleaned off very easily with a very lightly dampened cloth|
6 weeks of waiting later...the boxes were back. The finish is OK, but rather dull - I was expecting a deep lustre to the finish. I suppose the very reasonable price I paid to have them painted didn't include the labour to make them shiny! Using Zymol - a high quality car cleaner polish - each Katan took a good 2 hours of polishing to get them looking good - 4 times around each cabinet. Boring, but effective. Of course, the Ninkas took around 3 hours each.
|Upwrapped - the finish direct from the furniture refinishers|
|Here, its easy to see the dullness of the finish, and a little "orange peel" effect.|
|Here its clear that the label had been masked - but its not perfect|
|Crossover, connection panels, collars and plastic blanking plugs refitted|
|Refitting drive units - a cloth covers the new paintwork whilst the cables are resoldered. I did the mid-bass first to avoid damaging a re-installed tweeter.|
|Drivers reinstalled (this is the one shown covered in dust in the prep pictures above), just before refitting the rubber trim ring around the mid-bass driver|
|The first of the Ninkas to be rebuilt|
|Re-installing a Ninka tweeter|
|Looking good in the workshop|
|With the inspiration for the colour|
|Now with a decent shine|
|I don't have a set of the correct stands yet - here they're sitting on Atacama SE24s - the right height, but the top plate is too big|
|The flash is distorting the colour here - if you look down near the floor, that's more realistic representation of the true colour and the closeness of the colour match to the car|
|A better idea of the real colour in natural light|
|Pretty pleased with the final result|
