I JD 01, I was told that a proline 3000 would not be sufficient to run 4 x pd 186s (700w at 8ohms each).

A few hundred watts here or there once over the magic 1k a side doesn't make any difference.
I've got a Matrix STR3000 and some QSC PLX3402's. I only take out the Matrix when the QSC's have to do other duties. I can't tell the difference between them as far as volume is concerned, the QSC sounds a little tighter in my opinion and weighs about half of the Matrix. For me thats a no brainer.

Ah, you want to bridge the TA2700 Proline? That would be ok, but you should setup the limiters in your controller correctly to keep the amp from clipping.
But to say it again: If one TA3000Proline is not sufficient for 4 PD186, one RMX4050HD won't be sufficient too.
IDEALLY you would power the PD186s with 1200-1400W each.... but that does not mean you have too put that much power into them. Edited by JD01 - 14 March 2007 at 3:21pm |

I know for a fact they'll will play 4 cabs. Scoops, Folded Horns, 4'' or 5'' VC, any four cabs.
Maybe a bigger amp would play them better, but you may just blow your drivers.
My mate uses a 3000w JTS amp in stereo across 4 scoops (2 / side) no probs at all.

When I play out now, my friends ask me if I'm bringing "The Proline". Search the forums for Proline and you'll see my views all over it. I rate the 2700, the closest cheap amp to Crest 8001, MA2400, P3000, MX3000a. Obviously 4050HD/5050HD are quality amps, but serious guys I know running 4x 5" VC 18's of 1 amp are using VZ5000, CA18, P9001, Void Network 4. For some reason the Crown and Crests sound much more than the specs say. Peace. Edited by levyte357 - 14 March 2007 at 3:29pm |

@ Teksasis: This was meant only by comparison. A 2x1300W at 4 ohms QSC RMX won't give more output than a 2x1350W at 4 ohms Proline (or just a little more). So if one Proline isn't sufficient for his demand, the QSC won't be too.
QSC is spec'ed in the USA, made in China nowadays (even the PL6.0II is made by Soundking). The differences in the conventional amplifiers aren't that big.
The reason for the Crwon MA5000VZ sounding so fat is that it adds a lot of harmonics on the last 10% of power output.
The Crest PA9001 is a very nice amp, but veeeerrrry heavy too...
The CA18, yes, it's a good amp (also made in China), but you can get a copy that's even better than the original: BST Liker 3600 aka DAP Vision 3500 (they have more and bigger transistors than the original. Circuit design is the same). Edited by JD01 - 14 March 2007 at 3:42pm |

I Have found the lower I crossover, the more I can drive the 186's, but typically crossover no higher than 100HZ. So far I have driven my 2x 186 loaded bcsub18 cabs @ approx 1kw each. If the amp is configd' for bridge, thats one of the gains fully up and the other just over halfway. Check manual and get it right. That was also with EQ pretty flat !!!! Cut off German connector and put on chunky 13 amp plug. |

@JD, Have you or anyone you know, ever used this DAP 3500? I came real close to buying one, but didnt because a)4-ohm bridge is not recommended (IF I remember correctly, but it is on CA18) b)The Seller was using an internal picture from another amp on the ebay advert. Since then have decided, after I get 2nd Proline, will only buy top brand used sub amps. |

ooooooh my God so much false claims in one message 1- 2 amplifiers rated at same sinus output power under ideally 100% resistive dummy load could be very different with music and with real life capacitive speaker load. In fact, a CREST CA12 sound much powerful on heavy bass than 99% of Chinese amp, even those rated at much higher power. 2- Soundking is not the PL6.0 II manufacturer. Soundking doesn't produce at all for QSC and 100% of PL series is still made in USA. Afaik Gold Peak Industries in Huizu is the Chinese manufacturer of RMX line, and only RMX. 3- Crown 5000 sounding fat because of distorsion, this is the only thing true in all message, so I must give credit to it 4- CA18 is not made in China. another false popular myth. it's made in US. 5- please don't tell that BST Liker 3600 or DAP made by SoundStandard (SAE China) are better than CA18, you absolutely don't know what you are talking about ! SAE is a crap factory with loosy QC and with more than 30% failure rate on some series. The DAP and BST use low grade cheap chinese components compared to high-end fanous parts inside Crest. few examples : PSU capacitors are made by Philips or Panasonic for Crest and are long life models special for audio. Inside chinese copies there are HEC or RM foshan lasting 3 times less and costing 5 times less. Crest CA series uses hydraulic magnetic breaker with Rocket switch made by Airpax in US costing 35 US dollars for the 3 0 Amp version inside CA18. The chinese copies use Fuse costing USD0,02 and chinese power switch costing USD0,50. And so on and so on... |
