How about 2 prolines? Similar budget. Unless transformer isnt an option.
You could also hunt old classic transformers on auctions but its job for months. I dont think you gonna find impulse psu amps for that price. Its rather this http://www.speakerpower.net/store/p18/SP2-12000-DP.html kind of price range. Or some rebranded amps like powersoft>>outline or lab grupen copy. |

http://www.mlcaudio.co.uk/wp-content/uploads/2014/08/PQM-series-4.pdf Shouldn't it be fine? If not, what budget amp would be a good option? |

pqm13, like most similar 4ch amps, is not designed to drive low cycle/freq. loads all ch driven, specially not at low impedances..

Than 2100w/4ohm will give 525w per speaker (burst 1%). I would get all i can from this sae. This way above will be also safest (6ohm load on 4 ohm bridge).

Wouldn't it be easier to just wire each lab in series, resulting in 6 labs being 800W at 8 ohm?
This would mean I can wire 2 labs parallel per channel being 1600W at 4 ohm, leaving one channel unused. The PQM13 has 4 channels at 2100W 4 ohm. Wouldn't that be enough? Edited by Futendra - 04 July 2017 at 5:40pm |

I see. You could wire drivers inside labs in parallel and 3 labs in series will get you 6 ohm. Bridge amp.

As I understood there is both a 4 ohm (Eminence's LAB 12C) and 8 ohm version of the lab12s. They would use the 4 ohm versions in series, meaning 8 ohm per labhorn.

Guys they are most demanding around 40Hz where is the impedance minimum. You could bridge sae and have 3 labs in parallel but you will need to change wiring inside labs to series. So 5kW in 4ohm. 800w each speaker. What do you mean each labhorn will be 8 ohm? What speakers are inside? |

The labhorns are wired in series. I can't connect 3 drivers per channel. I can connect either 2 drivers or 4 drivers. Also, each labhorn will be 8 ohm, meaning 4 ohm if I run 2 in parallel. Which should be 3 channels total.

2500w/2ohm ~800w/6ohm.
My previous simulation was wrong(overexcursion) Watch out with sae this spec is for burst 1% thd and impedance will drop even lower: 0.47ohm*12/3=1.88ohm Sims were for 69.3V(800W on 6ohm). You need to use 4 channels. 12 speakers total so 3 per channel gives 2ohm per channel. Also concern the fact they have in spec 2100w/4ohm and 2500/2ohm. Its not a good forecast.
