Just about to start with the cutting on my companies Laser Cutter all the parts to make two MT121 Cabs loaded with P-Audio SN12B and Beyma cp750Nd's/TD460n horns Plans drawn up with my idea on the MF Horizontal Flare  Will post some photo's up as the parts get cut, also have a custom grill panels coming from our Finn Power Turret Punch where I work, 2500 hits with a dia 8.2mm punch done in around 8mins  Open to discussion on the curved section for the flare. I intend to form and laminate 3 layers of 4mm ply over some formers, idea derived from the speakerplans readers project HD15 curve lamination photos. Wish me luck! These will be going above Lab subs and Usb's |

Top & bottom panels pre-drilled last night, 12mm ply plant ons glued in place, SN-12B's on their way to my door... Jig to form the horizontal dispersion parts of the mid freq flare constructed, see how the Lamination goes... Cheers to all for the positive words first build of this scale, happy I've invested in quality ply & cnc router cutting this far |

Try a sheet-metal engineering shop in your local area if you want a custom design. Someone proficient with AutoCAD can draw up the profile for you, my grills were manufactured on a Turret Punch where I work. If you find a company with a Turret Punch & do a little research as to what tooling is available there, as working with what they have available will see the initial design go through to produce a really good end result. The holes in my design are 8.2mm dia, on 12mm circular pitch centre. |

Thank you people! I aint much of a photographer  but I'm very happy with the cabs this far.The curved section is made in a jig from 3 laminates of 4mm 3-ply. First one split a little so had so sand it back to smooth curve again, the second one came out as good as I could have hoped for! Ill be getting another 4 x cabs CNC cut in the next few weeks, going for 6 in total now Arrived yesterday 4 x P-Audio PH-4528 2" horns so I can now spend some time getting these finished! I do have the 2-D AutoCAD .dxf files I used for the router cutting at work, I can email the dxf's if you drop me a private message. Peace Jim |

1 sn12mb : 1 cp750ti <-- you aint never gonna blow up your comps :) I find 2 sn12mb : 1 cp750ti the mid section starts barking before the comp ever raises a sweat :) (mt122) |

Interesting info there Psytron, alternative??? I don't at all mind the idea of having my comp's running well below their limit, blowing them up was not the plan lol |

Cant say i have an alternative but this is an expensive driver (at least i paid a bit for it) for a single 12 section perhaps you only need about 60w for a similar efficiency comp. to my ears the 750ti does not quite come down low enough to meet my 12's dont take this as a final word as i am still playing with it :) |

What are you running on the sub/bass & where are you crossing up sub/bass > 12's > 750ti ??? |
