  1. An easy way to test the crossovers would be to borrow or buy an impedance tester, such as the Dayton DATS - super easy, plus it has many other uses as well. Once it is set up with crossover connected to the driver(s), just do a test sweep. Cheers, SS
  2. Sandpaper works ok, or a sharp knife blade can also be used to scrape off the laquer.
  3. There’s no replacement for displacement! 🙂
  4. You won’t be disappointed with the Faital drivers 🙂
  5. Cheers Rob. Completely off topic, but how do you find the Neat Iotas? They look like an interesting speaker. Cheers, Matt.
  6. Regarding the crossover, it is better if the components are spaced a little to reduce interaction between components. Most important are the inductors. Inductors should be spaced away from each other by several inches (if possible), and also mounted so that they are not in the same plane - mount them at 90 degrees to the other coils whenever possible to reduce the magnetic field’s effect on the other coils. Also, make sure when looking through the middle of any coil that you cannot see any other coil - this will also help to reduce interaction. Cheers, Matt
  7. Hi Rob, I also have a couple of spare 90mm units (black) with matching bolts and rubber washers. Torema would be a good supply option, I can help out contacting them for pricing if needed. Cheers, Matt.
  8. Further information: For sale is a Pass ACA pure class A amplifier V1.6, rated at 8 watts per channel. This is the Nelson Pass designed and sanctioned unit, in near new condition, Currently set up for single ended (RCA) inputs. As one would expect, the amp sounds superb, and has a very low noise floor - I used it on a couple of different horns and wide range speakers. The amp comes with the power supply recommended by Nelson Pass. It also has the genuine aluminium case and heat sinks. Pickup is available, or postage available at cost - I will pack it w
  9. Sounds exciting 🙂 A layer of clear coat, varnish etc will definitely help vinyl to stick. SS
  10. I don’t think anyone would be able to pick a <1% difference in enclosure volume. If the question is going to nag you however, redo the calculations until it’s spot on, then you’ll never have to wonder about it 🙂 SS
  11. Just a little tip, when doing the mitre cuts for the top, bottom and sides of the cabinet, do the cuts at 46 degrees instead of 45 degrees - it helps to get a tighter and better finish on the exposed corners.
  12. I’d go back to the retailer and ask for it to be repaired under statutory warranty, which may not be limited to a standard 12 month warranty. As mentioned, it is not a cheap piece of equipment and it should be expected to work correctly for more than 16 months. https://www.accc.gov.au/system/files/Warranties and refunds - a guide for consumers and business.pdf Cheers, SS
