Next Project: Arc 40 CBT Array

[Kevin K.]

Got a NEW PLAY TOY and gotta share it with you. I'm the proud new owner of a 5-channel Outlaw Amp. Rated at 120 watts into 8ohm or 180 watts into 4ohm. This thing feels like it's gonna be a BEAST!! Put it on scale, 56 lbs, no exaggeration! Couldn't help myself, had to open it and see what it had inside. I'm no amp guru, but it looks to be very well built. Cant wait to fire it up! For now, I will be using an old Onkyo Receiver as the pre-amp. The HDMI video went out on it but otherwise it still works fine. Will upgrade and order the Outlaw Pre-Amp when I order the next Outlaw Amp to complete a 5.1 or 7.1 system down the road.

I didn't get a chance yesterday to update the progress on the Arrays from this last weekend. Before I get to that, here is picture I somehow left out last week. It was the baffle being glued to the enclosure and I think the title "Got Clamps" would be appropriate.




Didn't get as much done as I would have liked this weekend, under estimated the amount of damping material I would need and this stopped progress on the second cabinet. Only had enough damping to finish the front sidewalls on one cabinet. Ordered more today and will have to wait until later in the week before I can do the other.

Here are the left front panels for both cabinets. Cut the lefts together out of one sheet and then cut the rights out of another, less scrap that way.



And here is a video of the machine cutting the panels. Thought some of you might like to see her in action, it's pretty cool. I'm only using 4 out of the 5 axis's available in these cuts. She is really something to see when using all 5 axis's. Hope this link works.

Hand room was going to be an issue for installing the damping on these panels, so it was installed prior to gluing the panels to the enclosure.



Here is the first cabinet with left and right front panels attached. Also crimped all of the terminals. Abandoned the ratcheting crimpers, and went back to the good ole squeeze crimpers. Serious hand cramps by the end but that's probably more related to my age than the number of terminals.



That's it for this week fellas, thanks for looking.

Pretty amazing of course. Several times I thought about requesting a video of that machine.

What's the prob with the ratcheting crimper?

Not sure what was causing it but I could pull on the terminals on some and they were fine and then pull on others and they were loose. All of the wire came from PE and it was all 16 gauge, but it was from a couple of different manufacturers. Maybe my crimpers are just worn out, they were used a long time ago in a business.

Yeah, I'm sort of giving up on spade terminals for speakers. First, there is the problem of getting a solid crimp on the wire, then
I have to fiddle around with getting a good connection on the speaker terminals, which sometimes is a real problem.

I'm trying barrel terminals these days between the driver and crossover, with a solder-on "tail" on the driver. The barrels are made for each other, so I just need to worry about a good crimp to the wire and I"m good to go.

BTW, that Outlaw 5 channel is awesome!

These aren't going to be ported, are they? If not, I'd also recommend some denim insulation in the cab as well to help further reduce the back wave/standing waves.

I really prefer to solder wires to the drivers also Don, it's pretty much bullet proof that way. In this case, that would have been a lot of soldering in close proximity to the Karelian Birch and it just didn't seem like a good idea, especially with my luck. The crimp on terminals I sourced fit the speaker terminals great so it was just a matter of getting a good crimp on the wires after that. Thanks for the kudo's on the Outlaw, looking forward to firing it up and seeing what it's capable of.

No, they are sealed Kerry. I already purchased 3 bags of Acousta-Stuf for the project. Do you think the denim works better or is it a price thing?

[Navy Guy]

Denim insulation works as well or better, is typically cheaper, and can be glued in place so it's what I typically go for. If you have the Acousta-Stuff already, don't worry about changing.

I gotta ask-
Are you planning woofers for all of that rear-volume you have there? Seems to me a pair of 8" subs and a plate amp might fit back there.

[ani_101]

what did you use for the damping pads and how did you cut the angles on those? Can we borrow your cnc???

It crossed my mind early on Ben and it is a lot of wasted space, but necessary for stability. For now the plan is separate subs, probably 15's, and two of them. This will give me the ability to find the best room placement for em.

Here's the link to the damping: http://www.parts-express.com/sonic-b...-x-24--260-530

And earlier in the thread I discussed cutting the angles with a band saw, works great! http://techtalk.parts-express.com/fo...82#post1302682


Can we borrow your cnc???

Are you gonna bring it back when you're done with it?

[ani_101]

Thanks Kevin, now that you mention it, I did remember reading about the band saw. It looks very neat on the panels....

Hmm, let's see what else can you do with a 5axis CNC router, after the boxes are done....

Do you have some sort of dust collection set up on the CNC?
