To celebrate Martin audio's 50th year - i thought i'd build myself a mini Martin audio modular stack! The whole thing is just 10 inches wide x 15 inches high, pair of boots for scale. 215MK3 bass section is a single 5 inch subwoofer (£5 ripped from a Logitech sub!) + 8 inch passive radiator on the back of the cab. Built from 12mm MDF, then 6mm ply outer. MH212 is 2 x 2.5 inch full range drivers (Also £5 from a Canton sound base!), the top is just for show. Powered off of a TPA3116 2.1 amplifier.  |

that is one of the coolest projects that's been on here this year!! I like it a LOT. ------------- ''Remember that the object of a subwoofer is to enhance the output of your main speakers, not overpower it'' ''Dubstep - an elongated electronic fart'' |

Fantastic! Love the modelmaking aesthetic to it. Sure beats the loads of 3D printed 'mini rigs' out there.

That's wonderful! But now you have to build the stack for the other side, and a full set of LE400's and a couple of H350 sidefills... |

Which Harrison amps would they have used? Thanks

Posted By: Earplug
Date Posted: 03 February 2021 at 6:06am
Well - I say Harrison, but you equally could have had other classic old amps, Crown, BGW, C-Audio, Citronic - or of course, Martin's own brand amps as well. I just mentioned the Harrisons because I have fond memories of lugging their 5kW and 10kW monsters around, like 30 years ago... ------------- Earplugs Are For Wimps! |

| I used a lot of Harrison amps back in the late 80s and 90s. The biggest one I ever came across was the the Xi2000. Would love to find some info on 5k and 10k ones. |
Posted By: madboffin
Date Posted: 03 February 2021 at 3:30pm
You could add RSD and HH to the list, but Martin didn't have any amplifiers branded with their name in those days (1980s). |
Posted By: Earplug
Date Posted: 03 February 2021 at 5:08pm
Yes - not much info around on those. They were rare. I think that the 10kW was similar to the Crest 10001 in that it worked down to 1 or 2 ohm loads. And IIRC, the 5kW was 2 x 2kW amps in bridge, ie 4 x amp boards bridged, 2 and 2. That didn't work below 4ohm, but was also a beast. Maybe 40/45kg. And dozens of MOSFETs. ------------- Earplugs Are For Wimps! |

I remember now that Harrison had a K Series that iirc comprised of the K2000, K3000, K4000 and the K5000. These were heavy amps with the K4000 being 3u. Those numbers did not seem to be indicative of the power ratings though with the K3000 (the one that I'm most familiar with) only being 650w RMS per channel at 4 ohms. |

A couple of PA companies I worked for/with down here used these - to drive ASS systems. Both brands imported by the same guy. They sounded great - but, as noted in the article I linked to, were not too reliable. Which meant carrying spares, which added to costs, which meant people soon moved on to other alternatives. You can't be crossing your fingers that the amps last the night. Or have to swap amps mid gig. That tends to lose you clients.  ------------- Earplugs Are For Wimps! |

That makes some interesting reading Earplug. Do you reckon Mr. Harrison had just seen the Crown Macro-tec range when he came up with the case design? The inside looks conventional multi- K135/J50 layout,albeit with some hybrid drive modules there. That big one would make a terrific wharehouse/barn heater i reckon. Or for small welding jobs. http://audiorelic.blogspot.com/2014/11/etapas-de-potencia-harrison.html" rel="nofollow - http://audiorelic.blogspot.com/2014/11/etapas-de-potencia-harrison.html ------------- Be seeing you. |

Ok - not too sure about that. Maybe Tony ASS would be able to answer those sort of questions. And the K135/J50 MOSFETs were definitely the flavour of the month for quite a while. Bomb-proof devices. The problem was the other circuitry around them. Sometimes simple is the best, eg the Maplin modules - but when you need high power levels, you have to do some clever trickery to deliver. That can introduce problems like instability, etc. ------------- Earplugs Are For Wimps! |

Thanks all! Yes, good to see Martin pick it up - some great feedback on there  It’s been a nice little project to work on, apart from those bloody handles! I’ll take a few more pics over the weekend.On to the next one, I’ve done the L’acoustics SB28/K2 stack, and the vintage reggae stack, what next?...

Seriously if you ever make any to sell I'd certainly pay good money for one. I cant stop thinking about your tini martin rig haha! I have the full size version in the lockup.
Truly amazing project that is :)

Amazing work! If I had the skills, tallent and time required to do something similar I would attempt a TFS780H/780L set, or perhaps even a TMS-3, in the case of the latter it would feel good to finally be able lift it or even move it around. ------------- Swedish Pro-fi diy-nerd - http://www.martinsson.cc/blog/" rel="nofollow - http://www.martinsson.cc/blog/ |
