The panels for the cabinet will be done by a professional company. Paint and overal finish will be done by myself. I take it the cabs have gone back to the Professionals ,

I understand that you want to see some pics ;)
Tomorrow I will post the pictures of the B&C cab. Why don't I build them myself? I just don't have the right equipment, and the goal is pro finish cabs. That's the reason I will only do the finish (paint, grill, assembly of driver handles etc.) Ps: on a dutch forum there are some nice TH-18's with powersoft plate amps ;) |

A small update
The processing for the complete system will be done by a Xilica XP3060. For amplification I am thinking of a fp14000 (copy) and a fp10000q for the top cabinets. And I bought a pair B&C DE800 drivers with two 18sound XR1496 horns. I also have a pair B&C 12NW76 drivers laying around, but they don't sim great in a reflex enclosure. The top cabinet wil be the next project A pic of the DE800 (with horn) and a 12NW76. And a pic of the S18CN. I have two more foto's, but since the build I have a new phone |

Nice! 12NW76 speakers are very sensitive and loud, but sure, don´t go low. I would not hesitate to equalize these heavily though. It can take some excursion.
I finally made my decision and bought 21DS115. Behaves very well, I´d say the same as 18SW115, except for that it goes few Hz lower. Let us know how do you feel about your S18CN build after some burn-in. |

Nikon and Canon people should not be married to each other. Why did you let this happen?

Yup, the nw76 isnt a great reflex driver. Mine are in sealed monitors. They dont drop very low, but produce a very nice tight punchy sound very well suited as vocal stage monitors. Definitely always require a sub when used as tops in a pa system.

Yeah, that value of Qts says although they will work in a reflex box and it'll be fairly small, you'll never get any significant low end out of them. But I bet they are good for vocals and fast transients, very strong motor in that relatively small driver with strong damping. I bet they'd make a good horn driver too with the right design.

The top cabs will only be used 100 Hz and up. So maybe the 12NW76 wil work. The aim is a small 12/1.4 reflex cab. The nw76 sims good enough tuned at 80 Hz but de cab would be +-26 L, that's pretty small, and the xr1496/de800 is pretty deep.
I am going to simulate some cabs with winISD, and in the end I will build a test cab. |

I'm thinking of a different low/mid driver for the top cabinet. Any reccomendations?
The relfex cab will be tw audio m8 style but then 12" format. The reason is because I can place flying brackets on the side for an U brace.

Probably the 12NW76 will be sold and as a replacement I was thinking of the RCF MB12N405.
It can handle double the power, and sims better tuned at 60 Hz (almost 3 dB louder). I hope the TH-18 subs are done by next week.
