  1. Source in Australia for bitumastic pads?

    Robayne Distributors sell the Bostik stick on sheets.much cheaper if you buy a box of them.
  2. The ultimate 2-3 way speaker.

    Clone the Sony SS-AR1. I believe all the drivers are Scanspeak and are available. These retail for about $35,000. From DIY Hi Fi- Sony uses premium cost ScanSpeak Drivers: xover 400Hz and 4000Hz Tweeter = 1" dome D3004/660000 with Tymphany’s unique AirCirc Magnet System Midbass = 15W/4531G00 slit paper cone Woofer = Scan-speak 22W/8857T-00 aluminum cone Review and pictures. https://www.google.com.au/url?sa=t&rct=j&q=&esrc=s&source=web&cd=2&cad=rja&uact=8&ved=0ahUKEwj7wLbZ9fLZAhVT0GMKHaSjCFQQFgg3MAE&url=https%3A%2F%2Fwww.stereophile.com%2Fcontent%2Fsony-ss-ar1-loudspeaker-page-2&usg=AOvVaw0pX7V_w4AZF0IQHVn_tBex
  3. DIY JBL Clones

    Or just buy a second hand pair of JBL Studio 590s. They are one of the biggest bargains in audio.Incredibly well engineered horn speakers at a giveaway price.Really only that price due to Harman's mass production. Look at their frequency response curves.Very few horn speakers regardless of price can match them for measured performance.They also sound really good and will do so with quite low powered amplifiers .They need a big room though. A shame that many of them ended up in mid fi systems because they were deserving of, and responded to, so much better.
  4. I think i might try some solid jarrah ones and I have some pretty special jarrah for the job. Audio Synergy used to make solid jarrah speakers and they sounded really good.

    The Cornscala would also be worth considering https://www.google.com.au/url?sa=t&rct=j&q=&esrc=s&source=web&cd=1&cad=rja&uact=8&ved=0ahUKEwja2a2syuvZAhUHFJQKHQhCDS4QFggqMAA&url=https%3A%2F%2Fcritesspeakers.com%2Fcornscala.html&usg=AOvVaw2gazBXthoQmzP8xptRms03
  6. I think there have been some very good points made in support of two way speakers here. Of particular merit are the arguments that crossovers can be simpler and less intrusive and have a lower parts value which makes them more economical and which means more can be spent on the quality of those components and other key ingredients.Mike's point that a three way using 8 ohm drivers with a crossover at say 200 Hz requires massive inductors is a very good one. As I write this I am listening to some vintage Tannoy two ways.Still one of my favourite speakers. I am also tempted to build some Devore Orangutan type two ways to see if I can replicate that sound .
  7. VAF DC X63 Speakers

    Yes I agree.That looks fine for most SS amps. How they have managed to keep the impedance above 4 ohms is a bit of a mystery but well done them. Perhaps the drivers are all genuine 8 ohm whereas most that are rated at 8 ohm are really more like 6-7 ohm and before you know it you are looking at 3 ohms when they are paralleled and that gets far more tricky. Hi Vi drivers? Looks even more of a bargain for anybody wanting a big easy full range speaker. As long as the default colours are not Port Adelaide Football Club!
  8. The best I have heard NS1000s sounding is with Bakoon amps. I would have said they sound best with a good push pull valve amp before hearing that.
  9. All the Rangers supporters I know have small two way speakers now that I think about it. What is that about?
  10. VAF DC X63 Speakers

    Not so sure about that.I have owned speakers with similar configurations of two woofers and two midranges using 8 ohm drivers and found them pigs of things to drive.Even more difficult that the Gale 401s.
  11. Yes I imagine those expensive SEAS tweeters should sound really good.Even some of their cheaper ones seem to sound excellent. My impression of the Focal 1038Be is that the bass lacked speed,texture and timing.Plenty of it but it was not very good quality.To be fair though a lot of ported speakers sound like that and some people seem to like that sort of bass. If you want to hear how bass should sound try listening to some Magico S3s or S5s.No ports in them.Beryllium tweeters too but they are very refined and subtle.
  12. VAF DC X63 Speakers

    They look to be a very high value speaker. The high sensitivity is interesting but you would need to see an impedance curve.I suspect it might dip well below the nominal 6 ohm if they are using 8 ohm drivers wired in parallel so might not suit low /medium powered amps.
  13. Aesthetics change over time.Thirty years ago wide speakers were considered aesthetically pleasing.The trend over the last 20 years has been towards narrow speakers. You can make wider speakers that look great .Some of the 1970s B&Os were wide but looked beautiful.The Gale 401a chromies look fanatastic. The new Yamaha NS5000s look great to me.It is really just about good design. The argument that wider baffle speakers do not image as well really comes from old speakers that did not but there are plenty that do and a good speaker designer can make wide baffled speakers that image very well.Magico for example. My Yamaha NS75Ts from the 80s have a 360mm wide baffle and they are one of the best imaging speakers I have owned.So even back 30 years ago it could be achieved.Today it should be very easy. The Devore Orangutans at the Melbourne Hi Fi Show were evidence of how good old style ten inch drivers in an old style wide box can sound.They were by far the best sounding two ways there.Indeed the makers appear to be exploiting the sonic compromises of the modern formula of small drivers in narrow boxes by producing something straight out of the 1970s and selling it at premium price[$16000].Good luck to them!
  14. Yes exactly. I am surprised it took so long to get there. Those little mid/woofers have probably got worse sounding the more overbuilt and over engineered they have become.Although you probably can't blame the makers for that because they have been forced to make products that fit in fashionably slim boxes playing fashionably artificial bass and all being driven by excessively powerful amplifiers .
  15. Floyd Toole presents some very interesting research. https://www.google.com.au/url?sa=t&rct=j&q=&esrc=s&source=web&cd=1&cad=rja&uact=8&ved=0ahUKEwihoPu95eLZAhWBWrwKHf2bCKwQtwIIJzAA&url=https%3A%2F%2Fwww.youtube.com%2Fwatch%3Fv%3DzrpUDuUtxPM&usg=AOvVaw3vzbRCBu2qSyTMj136teEn
