    In theory, perhaps, but there will always be some other issue to consider. Designing speakers is ALL about choosing your compromises, as there will ALWAYS be some, simply because the perfect loudspeaker doesn't exist - and never will!

    Indeed, and that's the right way to do it. However, as you say, you don't necessarily need the help of a computer to carry out those measurements.

    Wood? Where? 99% are made of MDF for obvious reasons: it is the cheapest raw material (price around 1/3 third of birch multiplex for example) and easiest to CNC cut. Cheap as raw material and you can run your CNC machine head at very high longitudinal speeds and still get pretty clean edges -LS industry loves MDF! :-)

    Yet in many cases still don't sound as good as the best vintage ones.

    Crappy paper cones with paper surrounds sound much better in guitar amps, but they're terrible for hi-fi.
    Lol - paper cones don't seem to hold back the sound of my Tannoy DCs in any way!

    And, pretty much every quality loudspeaker I've heard using paper cones has, to my ears, sounded fantastic. But then, I like the high-efficiency approach to loudspeaker design, driven by a nice valve amp.

    I think we are talking violins here, not speakers.

    Not that there is anything wrong with using MDF for a speaker cab. Or chipboard for that matter.

    I think you missed the post I was referring to (#66). Wood in musical instruments is chosen (partly) for its ability to produce sound.

    Yes I could use calcualtions but you'd have to be bonkers to do that. I can make a crossover change, and with a mouse click check the phase Is still tracking nicely and the Impedance/electical phase are still looking good.

    I completely agree that a loudspeaker doesn't have to be like a musical instrument, otherwise we would need a speaker like a violin for violin sounds, another for the oboe's and another for the kettle drums, heck may as well go and hear an orchestra in a concert hall or hire in a blues band to play in my living room (Where it would sound awful as the noise would be far too powerful in a small room).

    My Xbox One is made out of plastic and metal with some electrical components, no Maple, Cherry or Oak used, even my Cheviots are just an early form of MDF boxes with maybe some plywood for bracing. But they manage between them to produce a pretty good sound (Regardless of using my Quad 33/405 combo, Pioneer receiver or AIWA amp), I am sure the components of my Xbox One (Well the whole lot) is computer designed.

    But when it comes to speakers and rooms, the two parts of your Hi-Fi system that have a direct bearing on the sound waves that reach your ears there is a difference, and this is why a speaker is in many ways "Like" a musical instrument, both produce sound waves and some designs work for some, others for others, with an awful lot of input from the rooms they are in, and to dismiss all pre CAD designed speakers is a mistake.

    Marco is right, my point about the Stradavarius was to do with how they were made without any computers and I wouldn't have thought an awful lot of maths either, the only link is like a speaker it produces sound waves, some would say pleasing sounds.

    Yes, you are right. I have only read your posting but not carefully the one you were referring to so I missed the point... Sorry.
