Hales T5's Vifa's $ ohm or 6 ohm?
Uh-Oh. Was someone listening TOO loud or are you just not happy with the response of the tweeter after the mods that you've done? I hope it was the latter and not the former. Other than that, Madisound or Meniscus would probably be able to help you with the info that you need. Hope this helps... Sean > |
Not too loud. Just the same inbalance between tweeters as since when I first got them. Nothing blew. I am looking to upgrade to a high end tweeter with the hope to balance things out and upgrade at the same time. I'm getting the Seas Millenium but I may have to return them as they are a 6 ohm tweeter and my Vifa that came with the Hales has 4 ohm printed on it which is a good clue that it's a 4 ohm tweeter. I'm thinking maybe a high end Vifa. Maybe it will fit into the cabinet of the Hales easier than the Seas. I do not know if it's OK to exchange a 4 ohm rweeter for a 6 ohm tweeter. Any opinions? |
Impedance ratings are "nominal" at best and vary with frequency. You really have to look at the impedance curve and see how various drivers compare. On top of that, you have to look at the frequency response, sensitivity, dispersion and whether or not the original crossover had any notch filters / impedance networks built into the tweeter circuit. While replacing crossover parts is a walk in the park, replacing drivers is FAR more complex. Sean > |
Sean is very explicit BUT, things aren't that complicated since: you've worked on the x-over so you know (or the modder should know) the tweeter schematic. You can test the existing tweeter(s) to get the parametres & impedance/ amplitude curves OR, simply, back-calculate the "ideal" tweeter parametres based on the tweet's cross-over... The only thing you CANNOT do, I guess, is actually listen to a bunch of tweets to decide for yourself. Take a look at the LDSG for a few ideas. You don't need to hurry!! Cheers. |
