    Only my recollection of Agedhorse's story told on another forum. My first mention of it on this thread was noticed by the man himself so you can take it as fact.

     

    No, that's hearsay.

    Got any proper test data? Nope, it's all anecdotal preferences.

     

    On the other hand there is one well known trial where nobody could tell the two apart despite insistence that the class D was not worthy of the brand.

     

     

    Got any proper test data on this well-known trial?

  3. Well, this is what he says about it:

     

    Grundsätzlich ist mir der Preamp des 800b viel zu schlapp. Viel zu wenig Gain.
    Wenn man die Endstufe direkt (also wirklich alles umgeht) mit einem guten Preamp zB. dem API Tranzformer anfährt, klingt es um Welten besser. Auch über den EFX Return wird das Signal schlapp und träge. Des Weiteren verkraftet der Return keine hohen Pegel, es knackt dann immer wieder seltsam. Habe dies schon bei 2 verschiedenen 800b's erlebt.
    Obwohl grundsätzlich linear ist mir die ganze Preamp Sektion viel zu träge und schlecht.
    Da lohnt sich das moden meiner Meinung nach nicht.
     

  4. This is all a bit of a strawman. The instructions for assembling the crossover are on page 3. We're not using a PCB; we're using a chocolate block. The resistor is fitted against the chocolate block and taped (or tie-wrapped) to it, and the chocolate block is then screwed to the cabinet. If you wire it up this way, there is no chance of the resistor wires breaking.

     

    The heaviest component isn't actually the resistor - it's the coil. And the advice there is to screw the coil directly to the cabinet.

  5. While it's true that the resistor in the crossover isn't going to see much more than 8W, I'm a great believer in overspecifying resistors in power speakers, having seen too many burnt-out crossover boards in the past, where the resistors have overheated and taken everything else with them. The best place to get these in the UK is Blue Aran, where a 4.7 ohm 20W resistor costs 79p.

  6. Be aware that fitting a sub-baffle over your existing baffle will reduce the available space between the driver and the grille. 25mm is normally enough to allow the cone to move without hitting the grille, although it depends to some extent on the driver. If you have less than this, it might be a good idea to do a 'dry run' first, i.e. screw the sub-baffle in without gluing it.

     

    If this turns out to be problematic, you can always glue a sub-baffle inside the normal baffle. It can be done, but it's more awkward and you'll need to cut the sub-baffle in half to get it in.

  7. It looks like your PC isn't seeing all your memory. 470MB isn't particularly high usage. So the DAW isn't the cause of your problem. You can see how much memory your system is seeing under System/About (or search in the search bar for memory). Or, from the Task Manager (which you displayed above) click the Performance tab and you'll see the total amount of memory available to the system. You could also try the Windows Memory Diagnostic - do a search for it in the search bar on your PC. 16GB would be better, but you still shouldn't be using 95% of 8GB without any large programs running.

     

    One of your memory sticks might be duff (or not properly inserted) and you might actually only have 4GB available.

  8. I think I need to do some research on this. I loved the DS61 but also like the idea of using the midi keyboard with plugins. We have a Roland A-49, which seems to have a good reputation and has midi and USB sockets. Computer-wise, we have the choice of a (fast) Windows laptop, an iPhone or a fairly recent Samsung Galaxy tablet (Android). I've also got a small USB mixer that could be pressed into service. Amplification isn't a problem.

     

    The big question is the software. I had a listen to VB3m and it sounds amazing. My impression is that a fully-featured DAW could be a bit overwhelming for live work and that something simple (with high quality plugins) would suffice. My lad is doing A level music and can probably get hold of software through the school. 

  9. This one keeps coming up. I think you'll find, @Downunderwonder that the attenuator is just that - an L-pad attenuator as found in most bass cabs with a tweeter. A lot of people seem to believe it's more complicated than it is. An L-pad by definition changes the crossover point, which is why nobody but bass cab manufacturers - and 1960s Japanese hi-fi speaker manufacturers - use them.
