does it affect anything?
right now the lights are not clipping but getting a stinky smell from the driver.
I am just not sure if I should run MCAAC again?
I turned down the gain for now.
I would double check to make sure you have it wired correctly. With dual 4 ohm voice coils you can only wire it as 8 ohm (two coils in series) or as 2 ohm (two coils in parallel).
If you have the ability to measure the response you might want to do that and post the graph here.
I triple checked wiring and it is driver wired in 8ohm ---> speakon --->Inuke in bridged mode ---> XLR/RCA ---> pioneer SC-65.
Gain knob in front of inuke was turned half way up and then ran MCAAC.
When done turned gain knob another 2-3 clicks (I like it hot )
As for graphs, I do not have a mic yet and still do not know which one to buy, started reading rew.... and to be honest I was planning to do all of that this summer.
would it be better to wire it in 2 ohm?
I heard that you can set limiters, couldn't find how though? I do not know if that should be something I should do, Actually knowing myself....yeah that is something I should do
Any idea on the mic?
Once I set it to 8ohm, it calculates the watts automatically and now I can get the volume all the way to +10 with no smell!
I have a feeling a second one in the room might be in the near future.....
Now any idea what mic to get?
I am unfamiliar with the amp you are using.
Keeping the sub wired in 8ohms will put less strain on the amp.
I'm gonna build this sub, but it's my first one, and I know this isn't an easy first project, still I'm gonna do it.
Is the Behringer A500 with it's 375W RMS & 600W piek in bridged mode (8Ω) capable of driving an Alpine SWS-15D4 with a jumper (8Ω) wich is is 500W RMS & 1500W piek?
I like the amplifier above the INUKE because of it's silent working. It will be used for playing games and music, but I hope it will still have power enough to make my butt shake. xD
I'm now ordering the materials needed so tell me what you think, thanks :D
What will you do for EQ?
Well, I'll connect it to an Essence STX II 7.1 with some custom Op-Amps when it comes out :)
So, I'll control it with the sound card. Also my room is like only 7 x 16 so :P don't know what that will give, hope my room doesn't explode...
generally you want horn reflectors when you have paralel panels seperated by a straight horn flare that are at least 3 feet apart, as they can cause standing waves in the sub passband.
I sure don't think i'm clipping as I've checked the output of my minidsp with a cheap oscilloscope and i don't see any distortion in the sine waves. I've remounted it a few times and no change. I'm using the gasket included with the alpine, i haven't tried the duct seal stuff yet. I can feel air movement on the front side of the driver in the mouth, but it doesn't seem to be coming from the mounting holes. I'm not sure what to expect since this is my first sub.
Does anyone have any ideas what I could look for? Even if they seem overly basic, i don't know what kind of damage to look for on a driver.
I'm betting that the driver isn't properly sealed to the baffle. Try some duct seal on the gasket and make sure that the screws are snug.
I am curious though. I am currently using a single eD A7-450. How does the Wrecker compare to a sub like that?
That's a pretty hefty 18 in either cabinet, and it comes with a fair bit of amp behind it. The sealed version managed 120 dB in the Data-Bass testing, so I'd expect the ported version to behave similarly, but have additional extension. The tune is down below 20 Hz, but I have not seen an impedance chart for the ported version to know for sure.
Regardless, that is a decent sub you have.
A LilWrecker will keep up with what you have (given a big enough amp and a proper driver). I'd recommend stepping up to a bit more driver than the Alpine if you need the output. The CVX we tested with was running out of gas once we passed 120 dB (but then, so was my amp). A Fi Q 15 (basically stock, no added spider, low Qts, but the cooling/P chamfer options should be OK) should be a decent step up from the CVX, which is a step up from the Alpine, and it fits inside the cabinet as drawn. Unfortunately the Sundown X series doesn't physically fit inside the LilWrecker.
As far as I know, the Fi Q 15 has not been tested in the LilWrecker, but the simulations look fine. I've assisted others with measurements of a Q 15 with an additional spider, parameters were generally as expected (suspension parameters were stiffer, motor was unchanged) suggesting that the Fi numbers are reasonably accurate.
Regardless, I can't wait to begin building a sub to your specs!
1500 watts will take it a touch past xmax in this cabinet, but should still be well within xmech. It models a touch over 125 dB at that point.
In a nutshell, you're looking at a gain of about 6 dB, provided you have enough amp to get there and the effects of power compression are similar for both drivers. I'm not sure about distortion profiles, I've not done detailed measurements of either driver. Some day when I have the spare time and spare cash...
The XLS 1000 isn't nearly enough amp, if I was shopping in the XLS section, I'd look at the XLS 2500, bridged, I'd consider the XLS 2000 bridged as an absolute minimum.
