i might ask you few things in the futur, i m just starting to study speaker design ,very intresting... what made me want to diy my next speakers is that company want the cheaper cost for their monitors , so their is offcourse compromise in the design and company like adam, mackie, genelec ,k+h ,pmc ..use drivers you can find everywhere on the net . also their is some pre made kit, seems good for a first project . |

Kane i have already something to ask you ,with passive you use 1 amp for 2 speakers i guess? why in active monitors they use 2 or 3 amps by speakers? and it seems these amps are crap (except very expensive active monitors) |

You can either use one stereo amp for two speakers or two monoblocks (like the plate amps on active monitors).
Bi-amping is pretty common in active 2-ways because dome (and especially ribbon) tweeters are generally much more efficient than woofers. A usual efficiency for an 8" woofer is around 85-88dB @ 2.83v/1m, and the usual efficiency for a dome tweeter is around 88-92dB @ 2.83v/1m.
So, for example, if you have a woofer with an SPL of 85dB @ 2.83v/1m and a tweeter with an SPL of 91dB @ 2.83v/1m, the tweeter will play twice as loud as the woofer with any given power. Therefore, for the flattest response possible, the woofer will need 4 times as much power as the tweeter. (Remember that the relationship between power and perceived loudness is nonlinear.)
The only other solution to this is to add either an L-pad or a series resistor in line with the tweeter. This is only done in cases where the woofer and tweeter's SPL are only slightly mismatched because it wastes a lot of power from the amp, dissipating it as heat. Most monitors have adjustable L-pads anyway to compensate for bad acoustics.

okay, i hope someone give me a light here...
just got my mk2 active. I dont have soundcard yet in my lap, so i treid do test just one monitor in my laptop. But when i plug it, the sound is too faded, and if I remove just a little bit some of the bass come in and other freqs, but not a great sound too.
I tested it with my cdjs and the monitor played well. But when testing in my lap this happens, if a put the plug all the way, the sounds appear to low and without a lot of freqs, if I remove just a little bit of the plug a lot of the freqs come in but still not the perfect sound. I guess i can solve it only buying a external soundcard, but i m kinda broken right know, is there any other way to solve this? I was going to buy some adapters to be able to plug the two monitors in my lap, but now I will wait until I solve this.
note: I m using a normal cable 1/4 i think, with an adpter to plug at the monitor.

I'm not sure what connectors you are using, but usually plugging one monitor into a stereo source won't get you far.
on the laptop the connector is usually 1/8"...
Anyhow, while you're experimenting, please make sure the volume of your soundcard is set to low - you might harm the speaker. Also connect and disconnect while the amplifiers are off.
Get that soundcard soon.

you`re right, i m using a 1/8 cable of an old computer speakers, but i use an 1/4 adptor in one side to plug it in the monitor. My soundcard is onboard. When i plug the cable in my lap the sound that came out of the monitor is muddy and lacks lot of frequencies, if i take it out a little bit of the lap, the frequencies come back. If a plug another speaker (ipod speaker) on the lap with the plug all in, it plays normal. Anyone can give me a light?

^ There are so many things that could be going on..what do you mean by "some frequencies"? Treble, bass, or just some high end air? Are you using stereo cabling where you shouldn't/don't need to be? I would suggest just using what you have to isolate the problem. Use the monitors with another source and different cabling. If they don't work then it's the monitors. If they do, then try the monitors with your laptop and a different cable. If that doesn't work, then it's something wrong with the laptop, physical or not. Make sure you have all EQs, sound "enhancers", etc. in your player turned off. Make sure the laptop's headphone output is turned up.
But the fact that taking the cable out a little bit fixes the problem and that you haven't mentioned trying another cable or another adapter with it makes me thing it's a cabling problem. I suggest getting an 1/8" stereo to 2x1/4" mono cable.

hey kane, thanks for the help dude..
i dont understand too much of cables yet, but i think there is nothing wrong with the monitors cause i played them with my cdjs and it played well. What i mean by some frequencies is it lacks basses, and i think mid freqs too, the sound is really really low even i i turn up the volume to max, but if i take out the cabble from the lap just a little bit the sound volume turns up! just to give a crazy example, it is like when you are trying to hear people talkin inside in a room with your ear on the door.
hey, by the way, that is the cable?

When you used them with the CDJs, did you use the same cable with them? Are you only trying one monitor at a time or have you tried both?
That cable would work, but don't buy a Monster.
Go with this if you're going to order one:

well, i used the same cabble, but i really cant remember if i needed to take it out (rotten weed) but before i get the monitors, i had to do the same things with my cdj with my old speakers, cause if i pluged the cable all way in just one speaker would play.
just bought these on ebay

Could it be that your laptop's output isn't turned up enough or the signal is just too weak?
Yes, a Whirlwind is probably even better.
