Just finished building a 6x scoops system and I need some advice before processing with wiring and loading the drivers.

Here is the full setup.

6x Super scoops w 6x rbx100 b&c 

Running with crown itech 12000hd (3 scoop per channel)

4x es18 w 4 rbx 100 b&c 

Running with crown itech 5000hd (2 kicks per channel) 

6x 12ndl76 b&c front loaded running with 

Crown xti4002 (3 drivers per channel) 

4xDE25 b&c (yet to decide on amp) 

16xcp22 divided in 4 boxes of 4 (yet to be decided on the amp) 

Preamp :) 

So I’m looking here to have some feedback for those of you who have time :) also need some help on how to wire those tweeters properly. The question is how to end up with two boxes of 4 in one channel for example. 

Also I’m not very good at electric setups so I’d like some tips on the fuse panel and how to protect from power cuts and peaks (being in india, it happens all the time)

Hi Yaya, I hope you're staying dry!

Wire two tweeters parallel, then two more parallel. Wire those two pairs in series and stick

them in a box. Do this until you have four boxes of tweeters. Then wire two boxes in series, for 16r. Or two boxes in parallel for 4r (assuming the tweeters are 8r each). you could also stick a capacitor on each box to protect against low frequencies, just in case.

For protection, get a box like Ballu has. The newer, full power one. I have a stabilizer which is ok but super heavy because of the power requirement. I think Ballu's box is a better idea. A plug strip with a pop up fuse, which you can get there, would be a good idea for the preamp as a last line of protection.

Get that soldering iron out! Ha Ha!

See you in Hydra' on the 27th if not before.

So nice to read you here brother. I’m coming soon but I won’t be here till 15oct ! Will probably see you during the season.

Bringing all tweeters with me ! Haha

Thanks for the wiring tip, I wasn’t sure how to proceed with so many tweeters… 

For the capacitor, which ones you recommend ? Must be one per box ? 

Tweeters are 8ohm so yeah two boxes shall come to 4ohm.

I saw a picture of you building one of those old school coxone like boxes !!! So niceee !!! Can’t wait to hear it !! 

Lookin forward to read you !! 

Bless brother 🙏🏾

Hey Yaya,

Capacitors, one per box should do. My knowledge on this is not great and I'm only regurgitating what I have read here and elsewhere but a value which starts to protect one octave below the crossover frequency, it should have no effect unless something goes wrong. For an 8r speaker/box that would be a value of 13uf I think, if the crossover is 4khz. 10uf for 10khz. Hopefully someone with more knowledge will come along and can confirm that, or shoot it down and make a sensible suggestion. Try an online search for "capacitor for tweeter protection" or something similar.

Good luck Brother

16 of these?

Do you really need that many?

Thanks I’m going to look into it. Bought some bullet tweeters in mapusa and there was one condenser on each one of them.

Let’s see ! Thanks for the tips ! 

Hey @imageoven ! 

Well it’s not entirely my project, I’m building for someone actually and his aim is to have two stacks of 3 scoops sometimes so 8 each. That’s a lot, I know cp22 are really good but better to have more and not be pushing them I guess. 

I personally would do with 8 and see.

Having some trouble coming up with a value for the cap', crossing over at 8k. On line calculators are coming up with something between 10uf & 15uf, as protection cap. But we have seen 1.5, 1.6 & 2.2 supplied with the tweeters or replacement diaphragms.

Is someone running these CP22 in their rig, crossing over at 8k? What value protection cap' would you recommended for these?

No one ever used to in Reggae sounds and many still don't. 

As for values, 2uF for 16 Ohm or 4uF for 8 Ohm is a good starting point with a approx 5 KHz 1st order filter (6dB/octave). A slightly bigger capacitor will be fine.

Use good quality polyester 200V or greater, monacor do a decent range for decent prices, Cricklewood electronics is a good source in the UK

I gave up those things about 30 years ago. The o.p seems like a pretty up to date guy who I'm pretty sure wouldn't want to run his system without limiting or processing.
