Default My Sachiko Build Process

First of all.. many, many thanks and props to Scott and the gents over at Frugal. I ahve asked a lot of questions, and he has been very helpful.

I wanted to build some new full ranges for my living room. I have already completed some decware designs and wanted to try something new. i found, and fell in love with the Sachiko design. I thought they would compliment the existing furniture in the room so i decided to dive in.. yea, my wife might have rolled her eyes a little when i told her and showed her the designs, but she WILL come around...

Anyway. They are about 1/2 way done now, and I thought i would post some photos up here for you all to see.

Thanks again to Scott and everyone else on these boards. I love reading everything and seeing everything you all have posted. i only hope to contribute in some small way back.

I would love to hear any feedback you might have.

Way, way cool.

Keep the pics coming and let us know what you think of the sound once they're built!

That's pretty hardcore, working outside in the snow The mahogany will look beautiful when it's all put together! Are those Nirvana Regular 8's in the background of one of the pictures?

Thanks.. Yea, working outside in the snow isn't too bad.. (for short periods of time.) Yea, the Decware boxes have AN standard 8's in them. Those were my first builds, so i have nothing to really hold them against. I am planning on Fostex drivers for the Sachiko's.

Hello Jeremy, I completed my Sachiko's 3 days ago and am pleased to say I am delighted by their sound so far. I "broke" my Fostex drivers in using some old KEF Concerto boxes whilst building, and even so, there was some ongoing improvement in sound for the first few hours in the new enclosures. 300B, Shanling cdt100 with western electric 396a tubes. CAT5 cable. Music varies from Mozart piano to Flaming Lips to Eva Cassidy,Neil Young,Pink Floyd,Good Charlotte, so is very varied.
Sound is simply excellent, with musicality, tonality, soundstage to die for. Imaging is 3 dimensional and very lifelike. Bass is tight, punchy and tuneful with plenty of depth. As expected the midrange is fantastic. I heard new things on each of the albums I have listened to. I did not think this would be possible! I have them standing about 3m apart and 50cm from rear wall and 1.5m from corners, very similar to where my previous VAF DCX's stood. They are heavy and so have yet to play around with placement- will take a month or two for my back to recover from carrying them up the stairs from the workshop!
I used high density chipboard (yellow tongue floorboard) as this was only my second attempt at building a speaker enclosure, and really did not wish to stuff up 19mm marine ply sheets at their substantially higher cost (Birch is like Platinum dust in this part of the world!). Cabinets are accurate and glued with no gaps etc, inside finish is smooth and sealed, the outside I am not too sure about, their imposing size makes me think I will use a light coloured final finish. I am very happy to say that I am ecstatic at the outcome of this project, well done Scottmoose and all others involved in this design.

Getting the internal parts in was a bit difficult/fiddly( I think a CNC router and this process could be much simpler and more accurate!).
I urge you to not judge these speakers until your drivers have had some run in time, my drivers sounded simply quite horrible when I first listened to them in the converted Concerto cabinets, but started to become a bit more musical after a couple of hours, and have improved since, I suppose they have probably run in completely by now, at a guess about 40-50 hours. I have some photos of the build process(got a bit slack after initial good intention to photograph the whole process) in various locations, and will post them soon.

Seal them, take them to a panel beater and paint them gloss black. Listen to "Thus Spake Zarathustra" at full blast.
No matter what you do you can't hide that elephant in your living room, so you may as well paint it's toenails red and make jokes about it.

The Monoliths........ speaking of which, I will find and play the appropriate piece, thanks for the suggestion! ( Still not sure about the black though, but the panel beater is a good idea).
