  1. You'd need them to be just over 28ft off the ground to measure down to 20hz.
  2. So three years down the line, what's the outcome? My girlfriend is very intolerant of any noise and even though her hearing is terrible, she can't stand the sound of the neighbors dog barking. I don't even notice until she point it out.
  3. I've always used Chord chrysalis because that's what Naim used to recommend when using non Naim gear with their equipment. Curiousity got the better of me so I tried more expensive cables in the Chord range (and other companies) but although I heard differences, I always felt the cheap Chrysalis was the most neutral. You can't buy Chrysalis anymore but Flashback RCA cables sound just as good imo.
  4. There's no relation between price and performance. Cables do sound different but you don't need to spend much to get good performance.
  5. Others that may be worth a look at are, Proac, Audio Note and Kralk Audio.
  6. Easiest would probably be to set the crossover roughly where you think it should be and take a measurements with your mic somewhere near your listening position. Now reverse the polarity of one of the drivers and take another measurement. The polarity that gives you the widest, deepest null is the one you want to stay with for now.... Next, make a small adjustment to the crossover and take another measurement, if the null is wider and and deeper then you know you're heading in the right direction. Just keep adjusting until it's about as wide and deep as you can get and then flip the polarity and the null will be gone and you will be left with a flat response through the crossover. You may need make a few more adjustments to the crossover after flipping the polarity, but you can easily reverse it again to check your null looks good and make more adjustments if needed. Here's what a null at the crossover actually looks like - Link EDIT: If you can't get a null it's probably because you have an odd order crossover, and they sum flat regardless of polarity.
  7. Yes. Unfortunately your crossover doesn't know what the actual frequency response is, so when you combine the actual response with the filter, you could end up with anything. The best way is with a measurement microphone. When I setup my car sub I adjusted the crossover slopes until I measured the widest, deepest null (I'd argue wider is more important) and then just flipped the polarity to give a flat response - easy...

    If you willing to trade efficiency for deep bass then it is possible to get sub bass. It's not something i'd be interested in though because I value efficiency.

    Being pedantic here, but if it's a second order acoustic crossover it will be 6db down at the crossover (800hz). And according to LspCAD it will be about 14db down at 1.6khz. But even so, that big driver is doing a lot of work in the high frequencies.
  10. Bloated bass can be caused by even a small standmount speaker. It's not the size of the speaker but the low frequency extension combined with room gain, that causes bass bloat (basically a peak or peaks in the low frequency response). I know at least one of the large JBLs have an f3 (-3db point) of 50hz and should be fine in most small rooms.
  11. Good choice for the midrange driver (Vifa M21WG-09-08).
  12. Tracy Chapman sounds good on pretty much anything. If it sounds bad on your system, i'd throw it away.
  13. How could you possibly understand if you haven't either designed your own kit or at least experimented with existing circuits. Of course it's going to sound like BS to you.
  14. Finally got around to watching the video and I agree 100% with everything he says - even down to how he describes the sound of silver vs copper cables. I'm sure some will think what he says is sales talk but in my 17 years of trying loads of different components in various electronics, I know he's just giving an honest opinion.
  15. I know where glassy/bright is because i've been building my own speakers for years, so no need for me to listen. I was just curious to see if they sound like those measurements suggest they do. Nothing more...
