LOTS of questions, New to Amp's/Cab's...

    Hey, Guy. I just learned there is a LOT more to amps and cabs then I though...

    First, I play Funk, Jazz, Blues and some rock. (Just like everyone else?) And am in the market for a new amp/cab, My price is about $950 (Lost $50) total to spend on it all... So right now I am looking at several possibilities for Amp/Cab's

    But First my question...

    If I were to get a Cab that could handle 600W @ 4 ohm, and a Head that could handle MAX 200w @ 4 ohm, How would that affect the sound? Would that make it "Muddy" or "Dirty"??? I really have no idea...

    So right now I am looking at a couple Combo's (I'm NOT set on a Combo amp) So here is the Yorkville...

    Yorkville BassMaster XM200T 220w @ 4 ohm 210
    Yorkville XC115XC Extension Cab, 300w @ 8 ohm 115

    My question with the Yorkville is would it sound muddy with all that wattage? I've Looked and looked but COULDNT find the head thats in that combo, so I know nothing about it.

    SORRY, That a lot of info, but I would really appreciate the help, Right now I'm leaning towards the Warwick / Aguilar 112 setup. It seems to have the most promising possiblities. And fits the "Criteara" for what I want, and what an amp needs to sound right.

    Again, In case ya forgot... 600w 4 Ohm Cab, with 200w 4 ohm amp, would sound underpowered and "Bad" right?

    You would quickly run out of headroom and volume.
    If you turn it up, you'll hear distortion, and the low notes will not get enough power.

    A 400-500W SS head and a cab that can handle 300-400-500Ws are a better pair. And around 400-500Ws is necessary for usual practice levels or small-to-medium size clubs. 200Ws is a bit underpowered (unles it's tube with very efficient cabs, but these are not tube amps here).

    Yorkvilles: don't know, never heard them.

    GK: very nice clean hi-fi sound, good lows, but look rather for a used 700 RB or a 800RB. The 400RB is a bit underpowered.

    Warwick: haven't played through them yet, but I've heard them played. Not as clean as the GK, helps accentuate the midrange growl. It is nice, also.

    Aguilar GS112: while many say it has nice big, pillowy lows, they also say that it has weak mids and it gets lost in the mix.

    Just my $0.02

    Hopefully some others will chime in, too, to give you some better ideas regarding what to get.
     

  5. That depends. There aren't any 100% correct-for-every-scenario answers to this question.

    There isn't any inherent problem with running a cab rated for 600W with a 200W amp. The number on the cab is it's maximum thermal rating not the amount of power you need for it. However, you might well find that 200W won't get you enough SPL for your particular situation without overdriving the amp. If it does, then there's no issue, if not you need a more powerful amp (or more speakers or both).
    Personally, I would consided 200W to be on the hairy edge of what you'd need for a rock band situation, and I'd lean towards a more powerful amp. Say something around 400-500W.

    I'm not familiar with the Warwick amp, but I'd think that a 112 cab by itself probably wouldn't cut it in a typical rock band situation. I'd go at least 2x12 or 410.

    This is Just for my room for now, And If need be, I have a 115 that I could hook with the 112.

    Also the warwick is 400w @ 4 ohms
    The Aguilar is 300W @ 8 ohms

    Are all heads Transferable between 4 and 8 Ohms, Because there is no mention of the Wattage in 8 ohms...
     
  8. The Warwick would probably be around 240W@8 Ohms.

    4 ohms is the minimum impedance cab you can run off that head, so you can use any cab with a higher impedance (i.e. 8 Ohms :D) at the expense of reduced power. This is true for all solid state amolifiers, the rules are a bit different for tube amps.

    hey there.

    go to the sticky thread at the top of the page that says FAQ amp questions. click on the link that talks about ohms, impedance, etc. it's a long read but it will be worth it. You might also want to click the link talking about "how many watts do you need". :)

    anyhow, solid state heads can safely power any impedance equal to or above their minumum safe load. in the case of a 4 ohm minimum head that means either 4 ohms (one 4 ohm cab or 2 8 ohm cabs) or 8 ohms (one 8 ohm cab)

    BTW, cabinets arent X watts @ 8 ohms or X watts @ 4 ohms. Cabinets are either 4 ohm or 8 ohm cabinets that can handle a mximum of X watts RMS. ;)

    Hey Thanks a lot! I found that a little after I posted this, but before you told me about it!

    I've come to the realization that I am "Amp-Retarded"... I had this epiphany after reading about them in the "Sticky" note...
