At long last the enclosures for the Lorantz 15″ woofers are (mostly) done:
Big thanks to Col for helping with the build – his expertise gleaned from the multitude of enclosures he has created was a big help in streamlining the assembly process.

bass reflex enclosures for the Lorantz woofers now underway
After a very long delay I’ve finally gotten around to working on better cabinets for the Lorantz woofers that will unleash their full potential. Having adequate enclosures so I could be lazy and use the speakers as is no doubt contributed to the delay, but also some non audio related stuff got in the way as well, as happens.

low cost simple John Linsley Hood 1969 class A amp kit build
A simple build of one of the basic JLH 1969 Class A kits into a dumpster dived old amp chassis.
Used a 120W SMPS after reading in the DIYaudio forums lots of people getting positive results combining this older “classic” DIY design with modern quality switched mode power supplies.
I decided to build this to dabble further with Class A amplifiers after being quite impressed with a very well made DIY S.E.T. Class A valve amp I got to loan. One of the few gear changes my wife has made unsolicited positive comments about the sound.
TDA7297 15W chipamp
After reading the diyaudio forum thread I ordered some of these low cost units to play with. So far I have been pleasantly surprised how good it is, and how little electricity it uses.
The first unit I got (pre-assembled) I blew up trying to feed it 20VDC.. so lesson learnt, I ordered two more in kit form from the same ebay supplier.

BLACK MOY, Zoe Keating, Bersarin Quartett, The Children’s Encyclopædia
A quite varied range here, ranging through techno, modern classical, electronic (IDM?) and guitar ambient noise:
BLACK MOY: Parameters – some more nice meat and potatoes minimal:
Bersarin Quartett : pleasant orchestral sounding IDM.. or IDM sounding Orchestral? not sure:
found via mention on SNA forums.
Zoe Keating: Into The Trees – Modern Classical..but has almost an electronic austere feel to it.
The Children’s Encyclopædia – The Strings That Make The Music : floaty ambient electric guitar stuff.
two more from Sense, Further EP and Longevity EP
and he released a third one on Bandcamp today as well, though I’m still digesting these two.
I’m nore quite sure how many of these are back catalogue releases and which are new, some of the other Sense bandcamp releases are making the back catalogue available again.

PVC bass reflex port extenders.
The current 139 litre volume of the cabinets I’m planning need a two 100mm diameter 24 cm bass reflex ports to tune to my proposed frequency of 33Hz.. Any of the bass reflex tube products cost quite a few bucks to send over to Australia unfortunately. Thanks to the useful suggestions of Stereo.net.au forum members, I got the idea of making my own from PVC water piping, using a heat gun to form the flares. But I’m not so handy with being able to fashion them presentably well, so I went with a combined approach of using some less expensive fixed lenth 200mm long ports (the same kind from Altronics I’ve already used), with some 90mm PVC piping to make short extensions with flaring on the end.
Lucky I still had the offcuts from the ones I had shortened for the Econowave speakers so I could use that to check the dimensions were OK:
No Mystery EP : Sense
some ambient/drone from Sense:
Hostage – Generous, Random Walkers – View From The Outside
Random Walkers – View From The Outside
some dubtech with just a dash of pixie trance.
Generous by Hostage
IDM/techno elecronic stuff from Romania? but I like it.
