Adding active speaker to comdo ??

Discussion in 'Amps and Cabs [BG]' started by srj, Jan 27, 2009.


  1. I,ve been thinking about buying a small combo , such as a roland cube 100.
    I think this amp will need more power at larger venues (its only 100 watt , the external speaker is wired series so the max you can get out of this amp is 100 watt).

    I was wondering how to over come this in an easy portable way.

    So i thought could i connect the combo line out or head phone out to a self powered PA speaker ??
    Such as these:

    Any ideas or comments ??

    Thanks

    Realize that a lot of small "PA" boxes don't have woofers or designs made for reproducing a lot of content below 100 Hz. They are designedwith the assumption that if you really want bass reproduction that you will add subwoofers to the PA. So you almost need to try any candidate before buying to see if it works well enough as a "full range" cab for this application.

    Roland does have a D-Bass 115 extension cab that works great with the Bass Cube 100. I'd also recommend a Carvin LS-1503A as a sure-fire solution but I guess you are in Europe.
     
  3. Thanks for info,
    the roland extension cab is costly and big , i was wondering about some thing smaller and cheaper.

    Yes there are other subwoofers such as

    These might work but I better do some research on fequencies etc.

    I'm searching for a portable way to boost the cube 100s power with out costing too much or being too big.

    You could just line out to another combo, one that's lightweight.
     
  5. What you could really be thinking of is a rackmount head and variety of cabinets.

    I have a huge rig.. 50 watt rig.. down to a Roland cube.

    Overall.. I've found the rackmount with smaller speakers work..

    I've had the powered speakers crack up.. had the smaller SWR, Markbass stuff crackup.

    Unfortunately it seems.. that there's home headphone practice.. small acoustic gig (50W) and various versions of big.

    In any given weekend, I can be playing a Casino.. a dive bar (acoustic stuff).. then a brick church... Anything smaller than a rackmount head will crackup fast under an active 5/6 string.

    I've wasted too many bucks and hours on gear that didn't work.

    Unfortunately the micro amps are still being refined.

    HINT.. I did own a 150 watt 2x12 combo amp (guitar) that worked great for years.. we closed, tuned and ported the back.. I still use this on occassion... I think it cost me about $200 (used)

    You could always get a second Roland CB100 and slave one to the other via the line out. Then you'd have a backup. How much money is too much, though?
     
  7. well over all i dont want to spend more than 500 to 700 euro.

    I was thinking of purchasing the Roland Cube 100 ,,,there are some good reviews ,its light/small ,but it seems to be a bit under powered ,,so i was wondering about ways to boost the output.

    I just need a small portable amp for home practice and the odd gig ,,but you know how it is i didnt want to have an amp that was useless at the live stuff due to lack of watts.

    I'm open to suggestions ,,as maybe i should look at seperate amp head and speaker.

  10. Indeed you do get what ya pay for ,,but its about 700 euro for the powered cab,,the cube 100 is 450 e,,togther thats 1150,, thats too much for now.

    Will have a re think of the situation , even though the cube 100 is an interesting amp it might be better to look at a different solution.

    Why would you buy an amp that you know won't be loud enough right from the start? I'd consider other alternatives, even more powerful combo amps, if that's what you want.
     
  12. The cube 100 fits my needs for a small light amp for home practice and small gigs,,but i was wondering how to over come the power limitations.

    Unless you need the modeling of the Roland, why not get an inexpensive, but decent head, like the GK Backline 600 or Goldline 500? This is what I would have done, if I hadn't already had a few preamps lying around. The BL 600 is 300 watts at 4 ohms and gets good reviews. Add a couple of cabs, like two Avatar SB112's @ 8 Ohms and you'd have the option of a ~150 watt 1X12 combo or a 300 watt 2x12 combo. This would cost less than $1K (not sure about the exchange rate). Even less if you get one cab now and another later.
     
  14. yes i was thinking about alternatives such as the backline 600 and a 210 cab ,,,or the peavey tour 450 and a 4 ohm peavey 210.

    I dont have any experience with GK , but i did have a peavey practice amp that was indestructable.

    I don't recommend the GK Goldline cabs unless you're really strapped for cash. They don't use the wattage that you give them efficiently. The Avatars are better and about the same price.

    The BL600 gets good reviews here and elsewhere.
