So, the only way to factor inductance in is to test the real world performance?

What role does Fs play in the mix, say if you swap a 22HZ driver with similar specs but 32Hz Fs?

The horn sets the resonance by its length. The driver either copes well, or it doesn't.

That is where the simulation tools come in. The tools we have are invaluable, but not infallible. There are points where the assumptions in the simulations are less and less valid, so the the real-world results do not match the predictions.

While I have explored where this happens and try to avoid those issues in my current designs I don't know nearly enough acoustics and horn theory to explain why.

Interesting, thanks for the info.smile.gif

How much power am I getting out of the iNuke?

Don't have a number but it is more than enough to make the coil on my CVX let out some of the magic smoke.

I'm running 8 ohm bridged, according to the Behringer propaganda, it is rated to do 1250 watts. I don't think my clamp meter would respond fast enough to do a wide-open test and I know the driver wouldn't survive a sustained sine wave at this power level. I don't have a 4000 watt capable resistive load bank. if I compare predicted SPL vs measured SPL, I think the power comes up a bit short, but that is with a sustained sine wave, not a transient, so I don't think the comparison is entirely valid.

Nice part? Even at insane levels, I'm not hitting the power line hard enough to pop the circuit breaker. My EP 2500 tripped the same breaker.

Simple answer - plenty for my current situation.

Hate all you want.

There are similar amplifier options from both Peavey and Crown, but Behringer has the best integrated DSP implementation so far.

It's just hard to match the Behringer boom for the buck. They are nowhere near the best but do it reasonable well on the cheap.

I blew my 6000 Behri on the GH's and I don't think it should have been being pushed THAT hard but something happened. Haven't had a chance to look into it at all yet as it is 1000mi away in my garage. The power delivery was good up until that point, certainly great for the money ($369 rolleyes.gif). I don't know what happened at this point, we were running a bunch of other gear at the time and the keyboard player hit a note and pop..... It is the only thing that fried though other than the outlet which is also now dead. Who knows. I did read a test where it was noted it could spike the peak current demand up over 100 amps when asked for full output swing into 4 ohms. I think something like this may have popped the breaker which then killed the amp, or there was some sort of wiring botch in the ac line that finally reared its head. I will get it fixed under warranty and really try to abuse it when I get it back. I haven't heard of too many other failures and other guys have been beating the snot out of theirs,, so it may just have been a freak occurrence or a bad unit.

Not trying to prevent anyone from purchasing the Inuke's. There really isn't much that competes for the $$$ and hey, that is what warranty's are for.

Bummer on the 6000.
I guess it is part of the hobby. Something has to be blown up once in a while. mad.gif

My screwdriver bit fell out during my last fan mod and shorted the out the amp. Did some quick welding but blew out all the transistors. Ugh!

Ouch...Time for a couple plastic screwdrivers ?

In fall last year I thought I had blown a crest 8002 again and was getting ready to ship it off for service cause I couldn't determine what happened. Turned out the cord had been tripped over and it loosened and shorted the negative on the ac plug.

What is the upper range limit on the Micro? And what is the upper range limit on the LW?

I am thinking the Micro can be crossed over higher than the LW but wanted to see what you thought Mike. I am thinking if I go with the DR200's I will need 110-120hz capable subs. I can port the 200's for 80hz crossover but I am wanting the get the most spl out of them so I will port them higher.

Ya, I didn't realize the bit holding magnet crapped out on me. I almost never use the interchangeable bit driver, but it was a small torx which I only had a bit driver for. mad.gif

That is a weird one! At least it wasn't something major internal. The transistors on my amp were tough to source. I think each one was around $15 and there are 8 on each side. Grrrr.

Crossing the Micro at 90, but could take it to near 200 if I wanted or needed to. No way around using EQ, but the EQ should be possible via cuts only.

LilWrecker has a dip near 100 that is real.

110 would be fine. Do the Crowns XLS have a decent DSP?

Just wondering if anyone has used them is all. I liked the look of them better but it would be the 1500XL verse the Berry Inuke 3000. XLS being 50 dollars cheaper.

Crown XLS doesn't have a DSP. All it has is a HPF and LPF but the HPF only goes down to 50Hz so it's useless for subs. I had to buy a MiniDSP to make up for the lack of DSP in the XLS.
post #164 of 521
Well that clears it up. Thanks for that.
post #165 of 521
Few amps have DSP, even fewer low end amps.
I am not sure I would want to pay more for it when you can get better capabilities in an outboard unit.

post #166 of 521
I prefer external DSP's like the DCX but that is another 400 dollars. Minidsp is nice but I seem to not have a great track record with them. Either way hopefully I will see my new SWS in about 6 hours. biggrin.gif
post #167 of 521
Nah, more like $250 if you look around.
Either way, I wouldn't want my amp and EQ to both be dead at the same time.
post #168 of 521
OZ prices and yah one dead is enough verse the whole enchilada.

FYI, if you need one there is a new on ebay right now for $250 including shipping....
post #170 of 521
But what is the Input voltage? I know these are not Universal power supplies. Got my 15. Yay. Will have to fire it up to make sure it works.
post #171 of 521
Well its been a while since I bought a car audio subwoofer and this Type S looks great. Smells like a brand new car and I like the rubber magnet protector. Gasket ring easily comes right off. Wish I had a sealed box to throw this in to test. Just need to get started on the micro soon. I was pushing my Crest Pro 7200 in bridged mode with music and the woofer sounds quiet suspension wise. Will buy wood soon.


As you can see in the photo the gasket is easy to remove. It just slips off.

Anybody cranking any these out? I unfortunately have more projects than I do hours in the month, and haven't even ordered my drivers yet...
post #173 of 521
I am in the same boat.
I think I want to sell something as well to make space in the room and in the wallet.

I am slowly building a Micro if thats what your referring to.

LilMike is the PLUG supposed to be a 22.5" x 1 3/4" x 18mm piece?

The sketchup looks like it is an angled piece that maybe is 18mm skimming down to 12mm. It appears is all. And the back angled cut was not on the cutlist I have.(8 7/16" x 22.5) Just letting others know. Alright enough Micro talk. Is anyone building any LW's?

I really liked the look of that monster in the earlier pics and wish I could build them. May have to work something out.

Yes, it is, but I cut a scallop out of it to clear the driver surround. That might not be evident in the drawing revision I sent you. Let me check into this.

I have 2 that are about half way done. I just got the SWS's yesterday. I need to cut the hole for the drivers, make some bracing, assemble, slap some paint on them, then call a couple strong buddies to get them into the theater.

What changes, if any, would have to be made to use a 12 inch sub? I have a rockford fosgate T112D2 that needs a home. I built a custom 19hz tuned box for the first one but may build this for the second one instead of just duplicating the box I just built.
post #178 of 521
probably many changes, in fold and size.

Well, the answer is - it depends. With the right 12? Make the box skinnier and cut the baffle properly. How much skinnier depends on the driver in question.

I don't have time to run the numbers now, but if the specs I dug up for that driver are accurate, it seems like it might be decent, and may work OK in a tapped horn.
post #180 of 521
Thanks, if by "ok" you mean no better than a decent ported box I probably won't bother. We mostly use our setup for HT but nights like tonight max SPL is key. The ported box we made works fantastic but we love to build things from scratch and the art as well as potential of your design has us curious. We currently have 2 behringer 18s, 1 rockford t112d2 in our DIY box and the other in a car stereo shop prebuilt. My sons and I get great satisfaction out of building things you can't buy in the stores and this thread had had our attention for a few weeks. Guess it took a few beers to finally post and ask.
