hey,my name is elad levi from israel and i work with lab gruppen amps, the had wery clean and clear sound (fp series'& fp+ series) but crown 5000 sound much better and punchier for subs! sound componies in israel buy lab beacuse its have a low weight vs the crown 5000 but the dont ever tray the new crowns amplifiers (it 8000,macro tech 12000) that weight 12 kg only and have the same legendery sound. all the labs have low end for subs and very soft sound' some of the people likes it but not me. i think lab is sucks for subs and crown great for subs and the diffrent is beacuse the great damping factor of crown amps. it control in the subs more tight and more powerful! its get you more energy! you actually feel the curret that run out from the amplifier to the voice coil.. lab gruppen never Published the danping factor of their amps beacuse its sucks. for who that dont know what is damping factor and why it so importent- damping factor its the impedance at the amplifier output. the woofer is like a spring,when the woofer gets for exemple kick drum from the amp the woofer move and continus to move (like snear over ton) beacuse woofer speaker its like a spring, its send signal back to the amplifier, when the amplifier output impedance is low its "short" or reduce better the signal that back from the amp and control it better. the result is more sound at less moves of the speaker. like tight base drum. |

I have a duff Camco V6 here and believe me this MA5000VZ I just repaired sounds a whole lot louder. Camco won't supply diagrams or parts and unless a miracle occurs it wont be making noise for a long time yet.

pkn xe6000 will give you 2x 2.4K at 4 ohms continuous, with 2x3.7k peaks available, and trust me, it works on subs a treat.

yes, and then some ... although if you really want them to sound like an MA5002, you might have to find a way of dialing in some distortion ;) Early SMPS amps were pants .. the supplies simply did not have the peak current capability that the transformers had and SMPS got a bad name for driving sub ... theres still some crap SMPS amps about of course, but quite a few of the more recent models ahve it sussed and can now deliver bass just like their older transformer powered cousins. Also, the SMPS supplies typicall "sag" less under load, so you get better cone control and dynamics than you did with the transformer PSUs, but it comes down to design. |

yep, been hearing good things about the big ones (XT10,000 or whatever he decides to call it) Wish I could have got down to hear it at the ASS demo, by all accounts it was we received. |

Yes Tim.... PKN are serious amps, top marks to designers
I dont really need more power than the crowns give + i enjoy the sound & growl on subs (distortion, harmonics whatever)... but i like the power to weight ratio & value for money PKN offer.... + they apparently shook the place up when Ren played one pon his scoops @ rice & peas, however, people noted it played different to his usual bass sound. 2ohm (if needed) isnt a problem for the MA5000 + they hold value so well ... if PKN does the same in 15 years fair play to them.
