  1. It sounds to me that you have grounds for a full refund, including the return postage. Misleading advertising on their part, whatever the cause.
  2. In what way are they different? Drivers' performance does alter when broken in compared to brand spanking new, and these changes are permanent: bass response can go down a few more Hertz, sensitivity up a bit, etc, (the suspension frees up). Fresh out of the box is not what you end up with unless you never turn up the wick.
  3. [quote name='Japhet' timestamp='1476949491' post='3158649'] I'd liken the whole debate to the difference between petrol and diesel engines. Petrol engines may produce a lot of peak horsepower but produce way less torque than a diesel engine unable to get anywhere near the peak horsepower rating. People seem to be obsessed with horsepower, whereas torque is really a much more telling statistic. (I know much more about engines than I do about sound engineering ) [/quote] Petrol actually produces more torque than diesel when compared like for like. It's true. Believe it or not, it's still true.
  4. Practice slooowwwwly. The effort required to hold down a string is probably far less than you are actually applying. Work on using minimum force, and maximum precision, and go slow. Speed comes naturally, it is accuracy that you want to get into your hands.
  5. I picked up a small, dead guitar amplifier (Park, by Marshall) from a market junk stall for a few quid, because it had a spring reverb tank in the bottom of it. I was under no illusions, I thought the amplifier was trashed and I was right but I only wanted the tank. After getting home and a couple of minutes with a screwdriver later, it went into the effects loop of my four-track and Yay! 'verb on whatever I want. A few caveats: 1. it loses about 30dB of signal, a volt or two input comes out as a literal handful of millivolts, you need a following gain stage capable of boosting a microphone or moving-magnet phono cartridge up to line level again; 2. it is larger than most pedals and far more delicate; 3. it is physically microphonic, feedback can occur if it is mounted in a poor (or good?) location, it will 'verb if banged, etc. It's great. It's a Belton, specs. available online.
  6. I have an old Tascam four-track cassette deck which is also (primarily, for me) a most useful mixer. Four 1/4" jack inputs at the front, mic/line, effects send (mono) and stereo return, level adjusters, tone controls, pan, and stuff. Oh, did I mention, it can also record, bounce tracks, mix-down, overdub, monitor off-tape and record at the same time, etc. It runs off 12V DC. One of the best £4 I have ever spent.
  7. My immediate thought too, that location is awkward and while a patch-up might be good enough it equally might not stay that way long term. As you have decent insurance and they are happy to have it restored, getting it back to "as new" seems the bestest of all possible options.
  8. The left hand has to do things in time (before time) while the right hand has to do things at the right time. Which is more critical?
  9. Why does the string contact the fret below the one you are playing on? It should not do so.
  10. It's GOD'S OWN BUGLE! How do you play trombone without laughing? I can't do that.
  11. [quote name='BassTractor' timestamp='1473060082' post='3126382'] Bass trombone with valves? Wattage? Brand? Congrats [/quote] No. Variable. No. Thank you.
  12. [quote name='Number6' timestamp='1472036284' post='3117845']So any suggestions good citizens of BC? [/quote] Not what you are looking for?
  13. I would get £700 that I can't do anything with. I suppose I could scatter it on the bed and roll about in money. Other than that, nope, nothing.
  14. Ooohhh....! I would love 'em. Can I pleaz haz?
  15. I think six years is likely to be a perfect age to begin to learn to read dots - for bass she needs the lower stave (bass clef) of the piano. Would your son (drums/violin/piano) not be willing or able to assist/encourage (gently, of course, and slowly)? It could help him to develop (personally, but also musically) too. Try to ensure she learns good technique(s), but don't interfere with sloppy/experimental as long as she isn't hurting herself through straining.
  16. @onehappybunny, It looks like they are designed to go either way, try both and see which you prefer. Use a long instrument lead so that you can hear what it is like 20-30' or so away and wander about in the far field.
  17. [quote name='jonnythenotes' timestamp='1427463453' post='2730690'] This may be a complete myth, but someone years ago told me as sound leaves a speaker, it spreads in a way similar to the shape of an ice cream cone.. [/quote] This is quite basic physics. [url=https://www.google.co.uk/search?q=diffraction+of+sound&prmd=ivns&source=lnms&tbm=isch&sa=X&ei=tG8VVZDrNMnbasL0gIAC&ved=0CAUQ_AU]Diffraction of sound[/url] is similar to the behaviour of light except that the velocity is low, the wavelength is large, and the resulting diffraction is considerable. For very small aperture/source relative to wavelength the diffraction is virtually complete, i.e. spherical wavefronts and sound goes round corners. A free point source radiates spherically, equally in all directions. Block off the backward-directed radiation (e.g. with a cabinet) and you are left with a hemisphere, which is the basic form of the radiated wavefront from a relatively small source located in a large flat baffle.
  18. [quote name='onehappybunny' timestamp='1427460854' post='2730645'] Interesting stuff... do you think that there would be much difference in horizontal dispersion when using 2 x 12's (like the TKS S112's) vertically rather than horizontally as they only have one 12" speaker each? [/quote] Same thing applies, a 12" speaker is large enough to show phase issues at mid/high frequencies all on its own, more than one of them just exacerbates the issue. Using speed of sound in air = 340 m/s, at 340Hz the wavelength is 1m. As long as your source is relatively small compared to the wavelength then it acts "pointlike" which is good. You can regard 1/10th as small. If the source is of similar order in size as the wavelength then you can have problems, and if the source is large then you will have more problems. The G string of a regular bass is 98Hz fundamental, wavelength of about 3.5m, but the sound you hear is not a pure sine tone, it is replete with harmonics which may be many times that frequency. Playing the G normally at the 12th fret means the fundamental is 196Hz and harmonics are now multiples of that. 196Hz can be regarded as "of similar order" to 340Hz for our purposes so, as above, our source needs to be "small" relative to 1m or so, and smaller still for the harmonic overtones. A 12" driver is about 0.3m diameter, which is heading out of small and into similar order territory at a few hundred Hertz. At 3.4KHz the wavelength is 10cm, and any source larger than an inch or so in diameter will exhibit some phase issues just due to the size of the driver.
  19. Vertical stacking will probably give a better horizontal dispersion, which is likely to result in a more even spread of sound in the room. Vertical linear arrays can be excellent. Placed side by side there will be increased tendency to "beam" directly forwards and for comb-filtering to occur across the room, but the ceiling is likely to get a better spread (which is not of much benefit in most cases). This arrangement amounts to putting the cabs right up to a wall, it may boost bass but could well create boom (regardless of the nature of the floor). You can eliminate some of the latter problems by angling the speakers inwards, so they fire across each other. This makes them act more like a point source.
