My racks almost finished. Nothing professional, just for hobby  I tried to make a small and easy to setup system that would fit in my car. It consists of 2 racks. Rack 1: Mixer (Old school D&R Discom 1) 2 x 15 band equalizer compressor coming soon... Homemade amplifier 2x60W for small monitors near the mixer Rack 2: Active stereo 2-way crossover Amplifier for subs Amplifier for sats Speakers: Subs are MTH-30 loaded with thomann 12-280/8-W (In picture is a test woofer, not the thomann) Sats are own design loaded with thomann 12-280/8-A and Eminence APT150    |

go on then... what amps you running, lets have a look. your sat's, lets have a look at those too. ..i like the sound of it. its a nice simple little set-up. how you finding the thomann drivers then? didnt think they would hold up well in the MTH30. got any nice pic's of the rig all set up? ------------- If it sounds like a gorilla is trying to escape, turn it down. |

Interested in how the MTH30 performs with that driver... and would like to see a pic of it all too |

Sounds great to me. Better then a lot of small branded subs i heard before. Here is a movie of someone using the same driver in the MTH-30 Somebody made a simulation for me with the thomman 12-280/8-W driver  |

Sorry for the thread hijack! I've just built a double Cubo12 loaded with two of the Thomann drivers. Haven't had a chance to see what it like giving it the full beans yet but at low volumes it's average to OK.

...looking at that freq.resp. graph doesnt looking like these is much below 55hz..  build another 3 and see if it will get down to 45hz... ------------- If it sounds like a gorilla is trying to escape, turn it down. |

Well, the guy that made the simulation got his input for the MTH-30 from the internet and this could be incorrect. I'm not missing anything in the lower regions. Plan is to build 2 more in the future, so I can make a stack of 4. Currently I have a 2x300W/8Ohm amp for the subs, this will move to the sats, and the subs will be powered by an amp with around 2x1000W/4Ohm.

that will give you some nice head room and if stacked well should get you some very nice low-lows. cant wait to see pictures of the full setup... how are you currently stacking your MTH30s? ------------- If it sounds like a gorilla is trying to escape, turn it down. |

Here is an older picture of the sat, but with a piezo tweeter that I mounted while waiting for the APT150. Not sure if I keep the color, I had a tin of paint laying around :) A very small picture of the speakers in use for the first time  |

MTH30 is a 50Hz box as specified by the designer... that's the compromise getting such output from a 12" in a simple design Your Hornresp inputs look fine, they're the same numbers I've found to use for simming this box... and that driver looks like it sims well, what is the xmax? Should take a few hundred watts without trouble |

thats a nice diddy stack there fella... keep the colour "turbo blue" adds at least 10db to the output of any speaker! but, as a bit of constructive criticism, get your sats up at head hight. buy tri-pods or something but getting them up high means you dont need to rag them trying to get them loud as the 1st few people in the crowd in front of them will dampen the output of them. so next on your wish list: tri-pod stands! ------------- If it sounds like a gorilla is trying to escape, turn it down. |

I was told Xmax is between 6-7mm. My amplifier is 300W RMS, and I can give it full trottle.

When building the speakers I already made preparations for mounting top-hats. Every speaker has an extra strip of wood under the top plate screwed between the sideplates and to the top plate for extra strength. Stands will follow soon :) |

Would the thomann ta2400 mk-x be ok for four mth-30 subs? |
Posted By: mini-mad
Date Posted: 09 August 2014 at 7:27pm

they would kill your subs unless you limit the amp or YOU are very careful. the 2400mk-x is 2x650w@ 8ohms your drivers only handle 280w... just be reall careful and that amp weighs a fair amount (i have one as back up). for the drivers you currently have a 400w @8ohms would be fine. or failing that if you budget is around the 250 marck you may find a lighter weight amp on the second hand market. even a berry euro 2500/2000 would be lighter. BUT if you are gonna upgrade those subs to better drivers at any point the 2400mk-x is perfectly fine. JUST WATCH YOU LEVELS! ------------- If it sounds like a gorilla is trying to escape, turn it down. |

Thanks for the reply. Not planning on upgrading the drivers. If i want more power later i would build other type of subs with more low end extension. So can i also use the ta1400 mk-x? Can always move that amp to double sat duty in the future

thats a better amp for what you need... that one is 450 in 8ogm (nice little bit of head room!) its 17.5kg, the 2400mk-x is 20kg (give or take) so i hope your young and have a good back! i have a single tham12 with a PD12sb30 driver... and @400w it really does make some noise! if you have two of these bass cabs anyway there is no harm in building another pair and running them off the 1400mk as 2x subs off each channel will NEED 560w, the amp will give you 700w. again a small 140w of head room but those amps come with a 3yr warranty so you should be ok. and four of those cabs stacked like this..  ...in front of you with your ------------- If it sounds like a gorilla is trying to escape, turn it down. |

The calculated x-max HC-HG /2 + HG/4 = 5mm http://images4.thomann.de/pics/atg/atgdata/document/specs/283965.pdf" rel="nofollow - the Box 12-280 8W |

not the best.. but should give a fair amount of kick from a small cab. also as i pointed out a small stack of four with the mouths coupled will give you a little extra low end and ROUGHLY an extra 12db of output which means you should be able to get a hell of a lot of bass ooooooor... turn it down and have the same level you normally get and not over run the amp or the drivers. in a block of four you should be able to dip down to 40hz ish with out to much effort. just dont be tempted to EQ the bass to much to reach down REALLY low or you WILL kill them drivers. ------------- If it sounds like a gorilla is trying to escape, turn it down. |

Sounds great. And at only 50 Euro per driver really cheap. Not sure though If a single 12" midtop will be sufficient for 2 mth-30 subs. |

the point being coupling the horn mouths gives you a sort of a free boost in bass if you will.... and getting the midtops up nice and high at head level means you wont have to turn them up loud as they will be a ear level and wont be muffled by bodies as the would do just sitting on the bass cabs. they are just small tips to prevent you trying to turn the system up louder and trying to kill your speakers when there is only 30 people in the room. ------------- If it sounds like a gorilla is trying to escape, turn it down. |

...and those midtops will be fine for crowds up to almost 100 people at ear level if you dont drive them to hard and cut them at around 120hz and let the subs take over from there you should be good to go! ------------- If it sounds like a gorilla is trying to escape, turn it down. |

| Great. Sounds like good plan for expanding the setup in the future with reusing equipment. |

 kinda like this..... thats 4 MTH30 with the mouths coupled in front of you. ------------- If it sounds like a gorilla is trying to escape, turn it down. |

Very Nice  I think i spent around 100 euro per sub and 150 euro per mid-top including drivers. I think it is great value for money and they are easy to build as well. |

if you cant rock a room with at least 100 people in it your doing something wrong! lol and this can all be run off 2x amps 1x cross over and a little time and love. ------------- If it sounds like a gorilla is trying to escape, turn it down. |

Don't forget the double decks, they are better with mutual coupling too |
