Sorry, I assumed you knew the architecture of the iNukes
The key is a 6000 is essentially two bridged 3000s under the hood and a NU-4 6000 is essentially two 3000s in the same case. This is the reason the 6000 is not 2 ohm stable and can't be bridged since it is already a bridged 3000 on each of the two channels. Lukeamdman's tests of the NU-4 give you the information you need for the 3000.

Got you, I thought we where talking quoted specs. I know that tests have shown the inukes arent running as hot as advertised. I just bought 2 of the new ones and plan on running them each at 4ohm to one channel of the inuke 3000. Plan on putting them in a MArty cube most likely.....Thoughts??

Sign me up as another requestor of dual 4 ohm option ... I"ll take 4 @ $150 to add to the 8 HT18v1s dual 4 ohm I already have ... @Electrodynamic

2 HT18 dual 4 ohm drivers in dual opposed boxes off of 1 channel of inuke 6000 = great bass per $

Given the 2 inuke amp options on these, is there really going to be any discernable difference at 30db below max db levels.

Is it as simple as I would just lose a few db of max headroom..........or is there other dynamics at play here.

Only the 6k is compatible with nearfield bass.

And the quads are better too.

The reason people were wishing for a 4 ohm version of the driver is wiring them for a 2 ohm load gets about 750 wpc RMS from a 3000 so you can fully drive 2 on a 3000 and 4 on a 6000, as it is you have to decide to give them less than full power with an iNuke 3000 or have power to spare with the 6000 and spend $120 more. In reality you are probably only giving up about 2-3dB with the 3000 and 2 v2 vs a 6000 and 2 v2.
According to these measurements, the iN3k is about on point for 600wrms with both channels driven:

http://www.diyaudio.com/forums/class...surements.html

Quote:
Output Power:
No load max output voltage was 50Vrms per channel.

With resistive loads, power output at clipping was pretty darn close to:
300Wrms/8ohm/channel
600Wrms/4ohm/channel
1000Wrms/2ohm/channel
2000Wrms/4ohm/bridged
So that should put is right on the limit for the HT18v2, one per channel no? A iN6k should be able to run 4xHT18v2's with two in series on each channel, at roughly the same power going to each speaker it seems.

Or am I (probably) missing something?

I believe the new 18v2 is a dual voice coil driver, just like the v1; there will be 4 wiring terminal posts per driver which create 2 2 ohm connections per driver.

One of the reasons the Dual 4ohm option of v1 was popular is that you could present a 4ohm load of 2 drivers to 1 channel of the inuke6k ...

I finally decided to place an order for a couple of these, they'll make for great near field drivers in an enclosure I'll be building for them.

Now I just need to pick which iNuke to go with.

Not sure how accurate WINISD is but it looks like it takes around 1200watts to get these close to xmax. 600watts gets around 14mm xmax in 4cf and in a ported enclosure depending on size and tune.

I think it is better to have more power and not need it than to run something like a inuke 3000 on the ragged edge. For one if you want a quite amp the less your pushing it the less strain and heat and slower fans speed etc. That is how I look at it anyway. But it also looks like you are leaving a decent amount of output untapped if you need it going with the 3000 since you are barely using half of the subs xmax.

Edit, added graph comparing output in 4cf sealed at 600w vs 1500w which pushed it close to xmax. Looks like around 4db left used by going with the 3000 vs 6000 if WINISD is accurate and I have everything entered correctly. If someone already posted these comparisons I might have missed it as I read so many threads on this board

Are you just speaking theoretically about giving it 1200 watts? I see a lot of people mention powering it with much more than it's rated 600 watts RMS. Won't that damage it long term if fed continuously like some movies do?

I've been running mine with an 1100watt limiter for months with no ill effects. Lots of movies and dubstep with constant sine waves.

I think it would be hard to cook one of these under normal movie watching levels, unless you were working on becomes deaf.


IME, I have seen speakers fried by cranking up the volume quickly with way too many watts used to a level that could only be endured for seconds...or under powered/over driven speakers driven at crazy levels for hours on end at a large party.


I have seen lots of tweeters give up the magic smoke.


My cheap subs running at demo levels for MMFR held up, they started getting a slight wire coating smell towards the end.....but that was at crazy levels for a very long time and a epic soundtrack of non stop thunder at a crazy listening level that made m ears ring loud for a hour after the movie was over.

I wanted to test my system while it was still new and under warranty.........the reciever was smokin hot and so were the plate amps as I am sure were the mains........


Sure it is possible, but no matter how many watts you feed it, it will only use whats needed to reach X volume.......other than demo`s, the ears usually submit before the woofer.

I have seen speakers endure crazy abuse and seen a few pop for no reason.......they really are a wear item like tires on a car, it amazes me any of them hold up as long as they do given the constant movemet they endure for hours on end.


I wonder what produces more heat on the voice coil....under powered with loss of control/over driven or pumping max rated watts while still in control of the cone.......?

My guess is over driven without enough watts to control the speaker.....I have no idea, but thats my guess.

I would literally run that much or more and back off if it makes bad noises I am not saying someone else should do it, that is up to them to decide or ask Nick for his input on how much power they can take in the actual box/application the person is using.

I have never had any problems running more power to subs than they are rated for. I have probably had some luck and had subs that could take it(also ran enough subs that they weren't constantly needed to be ran 100% wide open to get the output I wanted). I also don't sit there playing sine waves thru my subs. For music and most movies, it is fairly short bursts on and off.

Probably one of the more extreme movies that I can think of is EOT intro scene, maybe there are other movies that are harder a sub, I really don't know. I suppose some music that has basically test tones or long drawn out constant bass could damage a sub when running too much power but it comes down to you have to know the limits of your equipment and how to set things up to prevent damage or minimize it.

Anyway, I just brought it up because I was checking what it was showing for xmax at 600watts in 4cf and looks like it takes at least 2x rated RMS to even get close to xmax so there is a lot left in the tank only feeding these with a single channel of an Inuke 3000 in my opinion. At least if the model is even close to accurate.

Yes, the question was more around the fact that a measured iN3k could actually match the necessary 600wrms per channel for two v2s and an iN6k could match the 1200wrms per channel for four v2s.

Ordered 2 of these yesterday. Going to put them in seperate sealed cabinets in a 1,200cubic ft room. Looking for a good deal on an inuke 6000dsp or may just do the 3000dsp.

The 3000 will only give a pair of these 500w each.

Use the 15% off coupon and free shipping. If the code won't activate once you are logged in call them. I think it comes to around $340 for the 6000dsp shipped. I would highly suggest the 6000 over the 3000. Always better to have a little more than you need that to be pushing the 3000 to its edge or into clipping. The new SI HT should be able to take a lot more than a DSP 30000 can give if the T/S parameters are accurate.

For example, go look at http://www.data-bass.com/data?page=system&id=90&mset=97 Stereo Integrity HT18D2 Sealed and how much voltage was needed to reach those numbers. That happening with a DSP 3000 and you won't even get that levels of output with a 6000dsp.

With the 3000 you would want to run the amp bridged to get more output but then that limits you from having seperated channels if you have the subs placed in locations that you need to set different delays with having them different distances from your listening position.
