High frequencies to the 1x15

Discussion in 'Amps and Cabs [BG]' started by Purdue Hoops, Jul 21, 2013.

  1. I just went to a Billy Sheehan clinic, and he said he sent high frequencies to his 1x15, and his lows the the 4x10. He said that the 1x15 had more "area" to make the highs stand out. Has anyone else experimented with this set up?

    Since they both have tweeters, I'm assuming that they're off and he's talking about the frequency response without them, otherwise they'd have the same highs response. It's possible he could hear them that way. Not going to argue with him since he's Billy Sheehan, but that's a new one on me.

    The "area to make the highs stand out" doesn't really make any sense. Could be that that speaker just sounds better up top.
  4. He runs one amp to the 1x15, and one amp for the 4x10. And thats exactly what he said. His bass also has two jacks. Thats how he splits his signal.

    the 4x10 has more area, and probably handles more lows, while the 15 maybe just carries the highs and any overdrive in a way he likes.
  6. The man can play bass, doesn't mean he knows how sound works.

    As Frankenrigs go, it's got a good headstart on doing it the other way around. Lucky for him to be able to demand the soundguys jump through hoops to capture it.

    Doesn't he play with a pretty distorted tone?

    Maybe the directionality of the 15 mitigates some of the "harshness" of his tone?

    It's also possible that he uses a speaker like the EV 15L which has a much higher frequency response than e.g. the 15B.

    If you use distortion you can't put it into a cabinet with tweeter without filtering. You want the filtering from a larger speaker.

    15s with no tweeters are cool for distorto-bass.
  10. Hi.

    The statement about "more "area" to make the highs stand out" could well mean:

    in reality.

    The 15"s generally beam pretty "badly" on highs, not necessarily a negative thing when used as a stage monitor. 18's are even better.


    How very true that generally speaking is.
    In all fairness though, we can't hold a candle to singers and guitar players though ;).

    IMO/IME being lucky has nothing to do with it. Any sound person(s) who You pay, would jump through the same hoops.

    15L with bridge pickup would sound fantastic ( in front of it ) on top if a 410 with a fat voice carrying the neck pickup.
  12. Have to be a careful with this kind of statement. Sure a 15" speaker beams sooner than a 10" speaker... But a 410 acts like a ~19" wide speaker so it actually beams sooner than a 15.
  13. Lucky I'm a native English speaker who doesn't get too cut up about usage lessons by a 2nd or 3rd language user. :ninja:

    He's using Hartke HyDrives, I believe.

    I don't think there is a bass player on the planet who works harder on creating his sound. Sheehan hears a sound in his head and chases it down like a pit bull. His method may be trial and error, but I have no doubt that when he plays he sounds like he wants to. He definitely puts in the time.

    Having said that, I believe that a lot of the things that work for Sheehan do not translate directly to other players. What I'd take away from the example is the value of thinking outside the box and trying new things.

    I think what he meant was that the higher strings are set to one output and that goes to the amp feeding the 1x15 and the lower strings are set to another output and that goes to the amp feeding the 4x10.

    The ads I've seen him in show him using the Hartke paper cone cabs.

    Ya, Billy uses AK's, which are paper cone.

    And I totally agree that Billy does a lot of stuff that doesn't translate to other players.

    +1, but that applies mainly to the mids. The highs from a 410 are comb filtered, because the speakers are side by side. The highs from a 15 don't comb filter.
