NICE!!! Thanks again dude! Black looks to be the best overall as far as smoothness goes, but that extra bump in the green looks pretty fun! I need to think about this a little biggrin.gif Either way, should be a nice stand-in until I can finish out the Shadow biggrin.gifbiggrin.gif

if i have that correct, here is the max spl for each combo.
(if the colors are difficult to see, from top to bottom they are red, green, black, blue)

red - shadow of the beast - 6th order bandpass
green - dual 5" long x 12" diameter ported, tunes the "cab" to around 11hz
black - dual 15" long x 12" diameter ported, tunes the "cab" to around 8hz
blue - sealed/infinite baffle



these are max spl numbers.

here is 4000 watts with 2nd order high pass at 10hz. spl and excursion.

in the big cab like that it will be pretty easy to overshoot excursion and i'm not sure how the re xxx is in that regard, so just be careful if not running any high pass and hitting them with big power.

also, winisd doesn't model inductance properly, so it is zeroed out. the actual response of the driver has a peak in the bass and rolls off on the top end. not a big deal for this application.




Listen. It's All Good.

Well, scooting that big mother trucker by myself stunk. But it is mounted in, wired up, and ready to roll. Bad news, headed out of town tomorrow so I won't really get to play with it until Sunday evening or next week sometime. I still feel accomplished at this point as I literally just have to power on the amp and do some measuring at this point. The lady of the house wouldn't be too keen on that right now so I will pick my battles. 120dB bass tests after bedtime is not one I want to pick at this particular juncture in my life biggrin.gifwink.gif

why do those clamps look so flimsy? Are those drivers screwed in too? or is it the sheer crazy largeness of the drivers?

drivers are not screwed in, but those clamps are 1 1/2" pipe clamps, they aren't bending. Looking at pics of the SI 18, people really have no idea how large they are. Lemme see if I can dig up an old "size" pic of them.

Well popped in the 15" ports, fired up the new superman and started breaking my house last night. The ported IB is insane. I owe everyone some graphs but I was more interested in just listening last night. Right now I am running the SI's and the IB together, full band (well, up to the 100hz XO) and they appear to sum pretty well together, but I really need to dig into some measurements. All I was able to tell is the bass was effortless while watching the movie, and my staircase might collapse by the time I am done...

I also just about smoked the coils on the RE's playing some Young Jeezy - Put on. I started getting the "stink" and backed off quickly. It was a close call for sure....

Epic setup, man. I missed the last few days of updates. Looks great, bro.

However.... lol, skip MoS (has little content <30hz) and move on to the proper demos. biggrin.gif I wanna know how all the greats do. OMFG HULK AND WOTW! eek.gif

Those will get a fair shake after I at least run a sweep or two and work on the blending with the SI's. Which clip is OMFG?

eh, maybe it was just some dust that had collected in the coils. It's all gone now, and it was pretty stupid to start out with the gain all the way up. Now at about 2:00 they seem safe and still work pretty hard, but not to the point of smoking. TBH, I was quite surprised that they lit up that fast, but I do guess 3700 watts of unchecked power can get something smellin' pretty quickly.

Yeah, I think we all probably got a chuckle out of those words be used together biggrin.gif

Glad you have it up and running, and that it's so impressive. It will be interesting to see the numbers, but I'm sure the experience can't be shown in numbers alone

Looking forward to those sweeps.

sidenote; 5 years ago when I started my HT; I was looking at and measuring the volume contained in that wasted space under my basement stairs and wondering "what-if IB", but I decided could never be made to work properly.
Then damn!! along comes this thread and a "ported IB" cool.gif

Alrighty!!! So what do you guys think? 1/24th smoothing as well



Blue is combined, Red is the SI's on their own, and black is the IB. Only two cuts to get there, it seems pretty solid, but I didn't get much gain up top regardless of how I set the delay on them. Right now they are identically set phase/delay wise and both setups are running full sub band.

Yeah, looks good!
I've had OmniMic from the product launch, whatever level of smoothing you're using, that's exhibited below 30 or so in your graph, ... is something I've not seen. Neither here nor there, curious is all. Nice results, the total combo is bad-ass capable.
edit; somehow, I missed the 1/24 smoothing label, maybe you coulda put it right above the graph or something rolleyes.gif it's hell gettin' old ...

Man that looks good!!!

So,

at 15 - 20 hz you are getting more than the equivalent of adding 8 more SI's!!!

which is awesome!!

however, at 10hz you are getting the equivalent of 24 more SI's?!?!?!!?!? Is that right? An increase of 12 db's from what you have at 10hz would be the same as having 4 times the amount of SI's or 32 SI's total right? Holy f..... I could be completely wrong here, if so please correct me. redface.gif

Not to mention how amazing that curve look - at 1/24th smoothing to boot.


I'd say this is a massive success right?

He's got 12dB more ~10hz which in "more subs" talk would be quadruple. I believe Brandon has a pair of dual-opposed SI's currently so that would be equivalent to having sixteen SI's.

My Dual 18" LLT subs 120dB down to 10hz

Krypto would be sososo happy seeing ported ibs like this!!! I still to this day think about him and his unusual habits and endeavors trying to find his happiness from what subs he had to play with at the time. Nothing was out of the question when trying to dig a little lower and louder only to have his little satellite LCRs drownded out.

Looking at this again, interesting. I'd be curious to experiment with various low pass points on the rear sub to attempt to further optimize the FR through the modal region, ... and perhaps filling in the crucial 50-80 region.

Having never fully explored blending a mixed alignment system, I'm just not well versed in what you're up against. I would love to examine what transpires upon sealing the vent in the rear, and temporarily employing it as a sealed/IB, then explore fully additive summation across the full band. I've also have zero experience with such a ported IB, and how elements like any type of lossiness, leaks, or internal damping, etc., influence the output, and can those items be attributable to the FR behavior up top? I've no clue, ... anyone?

Obviously, splitting hairs here, as the bottom end of the system is significantly increased, and the FR is very nice, but wth, still curious.
