paulears Posted August 22, 2018 Share Posted August 22, 2018 I see Andrew Bishop now has 7K a channel stereo amps for sale - that's going some, 7000W RMS into 2 Ohms. website link here Link to comment Share on other sites More sharing options...
themadhippy Posted August 22, 2018 Share Posted August 22, 2018 They look very similar to lab gruppen Link to comment Share on other sites More sharing options...
dosxuk Posted August 22, 2018 Share Posted August 22, 2018 I think "very similar" is being polite! It's almost identical to the Lab FP14000, just missing Lab's NomadLink stuff. https://www.labgruppen.com/Categories/Labgruppen/FP%2B-SERIES/FP-14000/p/P0CNP#googtrans(en|en) Link to comment Share on other sites More sharing options...
Brian Posted August 22, 2018 Share Posted August 22, 2018 Hmmm, a 20A Powercon used for the mains input... 240V x 20A = 4,800W. For a 14kW RMS amplifier? Also, 7kW into 2R means 120V RMS on the output connectors, which are terminal posts, which means it can't satisfy the Low Voltage Directive to enable it to carry a CE mark. Plus, that style of terminal post isn't rated at 60A. Link to comment Share on other sites More sharing options...
skinda0 Posted August 22, 2018 Share Posted August 22, 2018 What speaker connectors would you use for those kind of power levels? Speakon are only rated for 40A continous and 50A at 50% duty. I suppose they could do 60A but at a further reduced duty cycle. The LabGruppen FP14000 gives a peak output current of 90A and voltage of 195V though!

Shez Posted August 22, 2018 Share Posted August 22, 2018 240V x 20A = 4,800W. For a 14kW RMS amplifier?Come on Brian, we all know a 14kW amp will never draw anywhere near 14kW from the mains B-) Link to comment Share on other sites More sharing options...
TonyMitchell Posted August 22, 2018 Share Posted August 22, 2018 The first thing that always comes to mind when seeing these ridiculously high power per channel ratings, is why in 2018 some manufacturers are making boxes so ridiculously inefficient, requiring such power levels.

Does anyone even make a box that will handle that kind of power? There are various power hungry twin 18" subs that can take those levels when paired down to 2r/channel Link to comment Share on other sites More sharing options...
dosxuk Posted August 22, 2018 Share Posted August 22, 2018 As the 2ohm rating indicates, it's not designed for one box - it's designed for several boxes. I've used the Lab PLM14k's loads of times with 30k of subs hung off only two or three of them. Interestingly, the PLM's all use the larger 30A powercon rather than the 20A.

Stuart91 Posted August 22, 2018 Share Posted August 22, 2018 Does anyone even make a box that will handle that kind of power? If the rating is into a 2ohm load then I'd imagine the intended use to be driving multiple boxes. A pair of 2x18" cabinets per side wouldn't be ridiculous. However if I was spending that kind of money on the boxes themselves, I'd prefer to shell out a little bit more and get multiple amplifiers. More redundancy and probably better performance driving a 4 or 8ohm load compared to 2. Link to comment Share on other sites More sharing options...

csg Posted August 22, 2018 Share Posted August 22, 2018 these look very much like Sanway ( Chinese clone manufacturer) copies of Lab FP14000's. interesting that he has chosen to say that they are made in the north of England. Whilst the "made in" bit may only need to identify where the last major manufacturing process was carried out, I think that probably needs to be a bit more than an inspection / test. 14 day lead time with 10 available is very much the air freight delivery time from china too... as to the output levels being useful, yes, absolutely. Our amplifier hire stock is centred around Powersoft X series which offer 5200w into a 2Ω load. These units will in-fact only offer this output for a very short time, enough to carry the dynamics of a music signal with a crest factor of 6db or so cleanly, but the actual sustained power output is significantly less, along with RMS mains draw. Professional speaker systems have in part got slightly less sensitive than their 1970's counterparts due to several factors, mainly due to the bandwidth ( subs are expected to play much lower than even 20 years ago) but this is not an issue in reality as modern amplifiers with very high dynamic headroom are much much cheaper than ever. D&B are following this trend with everyone else with their current D80. Link to comment Share on other sites More sharing options...
