Great



Tell me if this hookup diagram is any more helpful than the line diagram I sent you.

If this confuses you in any way, pitch it and use what you do like.


Each subwoofer is a dual (2ohm) coil. In this diagram, each driver is config'd with the internal coils in series.


Thus, each driver represents a 4ohm load.
Each pair of drivers are in series, representing an 8ohm load.
There are four 8ohm loads, all connected in parallel, thus totaling a 2ohm load ... all on one channel of the amp.

Any reason one works better than the other? Like this:


They're the same, if you look again, there's four coils in series, in both images. But, actually the 12v calc one is a bit unconventional, hitting one coil in the next adjacent driver, then coming back thru the other side. It's unconventional, but visually maybe it's simpler because lines don't cross.

Doing so is unorthodox IMO, typically you config the two coils on the same former prior to leaving that driver ... you don't leave the driver then come back thru the other side ... weird. Typically you do it as I showed in both mine and as John showed.

My drawing. This is each of the terminal blocks that wire to each individual VC inside the box. Glad I did it this way after all this wiring stuff smile.gif I would have had to pull all the drivers after getting this all sorted. I have a fundraiser this evening and have no idea how late it will go, but might have time to start wiring this evening. If not, then itll be tomorrow first thing for SURE!

Looks good

Fundraiser rolleyes.gif

Your fundraiser, is this a trip down to that über busy intersection, ... standing there soliciting cash with a sign reading "will work for new drivers", is that your idea of a fundraiser?
Dude, just ask man, we'll all help you out.

I tried that sign, people kept asking me who I was chauffeuring around town, or if I was starting a taxi service biggrin.gif Haha. Just got home from the fundraiser for "Housing assistance." And no, it's not my own assistance. Too tired to wire up stuff tonight, especially finishing loading the last box up last night/morning around 4 am. Time for some rest and I will hit the ground running tomorrow biggrin.gif

FOH...this means power going to each driver would be one channel of beast's amp rated at 2 ohm single channel divided by eight?

That's the config he's striving for.

~456w/driver

Then he can use the other channel for the monster band-pass sub in the rear of the room.

Any reason one works better than the other? Like this:"

the car stereo diagram has the 2 VOICE COILS wired in PARALLEL, 2 ohms per coil, gives 1 ohm net per driver.

then it has the 4 DRIVERS, 1 ohm net per driver, wired in SERIES to produce a net of 4 ohms total.


other method:

my picture had the 2 VOICE COILS wired in SERIES, 2 ohms per coil, gives 4 ohm net per driver.

the it has 2 DRIVERS wired in SERIES, 4 ohms per driver, to produce 8 ohms per PAIR

then it has the 2 PAIRS, 8 ohm net per PAIR, wired in PARALLEL to produce a net of 4 ohms total to the amp.


there are reasons why my suggested plan will be better, at least in theory. from a practical perspective, the only way to know would be to test.

Listen. It's All Good.

Yours and Kevin's drawings, and mine actually all align at this point smile.gif I am about ready to finish up the wiring shortly smile.gif Then I need to recruit some buds that take payment in buds and tuna steaks to help me lift them up onto the danley's.

You missed a very fun, but interesting Mardi Gras parade that we just attended. Pisgah Pale in hand, we had a pretty good time with our whole kickball team, "Pitches Be Crazy."

Welp, I have all 8 running. It is intense to say the least. I have just been playing them by themselves for a little while, and I can get things moving all over the entire house. I don't even have the other two boxes mounted on top yet, they are just sitting in front of the bottom two. Getting them up top should clean up the response obviously a little better in the time domain, but man......I have already put the peavey into protection a couple times just seeing what one channel is capable of. I still wish I could run 4 per channel at 2 ohm as the drivers are still just loafing when I am running into the limits of the amp, but at that point, I am at reference with the subs almost 10dB hot, so I can't complain too much there.....AND I don't have the shadow OR the 2242's running. Right now I have the DCX out of loop too so there is no EQ. I need to get that back in the mix and start dividing up the FR with the Shadow and SI's taking care of the low end and the 2242's handling something like 40-50hz up to the XO point which is currently set at 100 or 120hz. Just playing right now until I pop the boxes up top, but having a WHOLE lot of fun wink.gif

My nice view as I close out the listening for the night. Man I like this sight! Seeing a few of the woofers is a whole lot of fun, but I can't get the screen back up until they are stacked biggrin.gif

If they are wanting to get over here Monday evening for the Bachelor finale, they might have to end up doing it themselves. Now that would be a sight.

maybe it is the light. maybe it is the proportion. its baffle proportion is close to the golden ratio. the woofer location is close to the golden ratio. who knows.

So, I don't want to bust up Jbrown's thread with any more questions, but I have sourced some Linacoustic or the like that I want to pop on my front wall and up to the screen on the sides. I have found 1.5 inch and 2 inch locally for a decent price but no 1 inch.

I have also gotten the suggestion to do 1 inch, with 3mm "poly" which I assume is short for polyester?!?! and then another layer of 1 inch Linacoustic on top of that.

I felt like just tacking some 1.5" on there and calling it a day would be fine. I also think that the 5 2x4x2 inch panels of the front wall are probably close to being efficient enough on their own hand. Anyways. What do yall think? Get the 1.5" linacoustic and make a nice reflection-free space back there and call it a day?

beast....3mm poly is 3 mil thick polyethelene plastic...someone mentioned earlier some good places to look...comes in rolls or folded...also Home Depot or Lowes paint departments is a good place to look...both like to have the material there to be used as drop cloths.

Yep, found some smile.gif I need to decide now if I can manage two layers of 1.5" thick, or if I should stick with 1" and 1". I can get the 1.5" today and start work on it tonight if so. If not, it will be next week before I could get going and that won't make the lady too happy with all her girls coming over to watch the Bachelor finale Monday night :/

Who is a good room treatment guru around here to get a quick answer from? I have talked a little with the GIK dudes, but the 1" ply 1" approach is an erskine design, and I really can't see how an extra inch of absorption would really affect anything that negatively. How are guys attaching the duct liner to the walls also?

The extra inch of thickness is only an improvement in this context, IMO.

Yep, my thinking too. I can't see any detriment other than taking up more space, and costing a bit more $$
