What is the best 1000wrms sub?

[Kyle_Keating 10+ year member]

I am bout to buy a 1000wrms sub and I was wondering what I should go with.These are the ones im lookin at:

IDMAX v.3 12" D4

RE SX 12" D4

RF Power T2 12" D4

Alpine Type X 12" D4

JLw7(I wish I could use this sub but it has weird ohms crap...)

I was set on the IDMAX subwoofer but then I saw this.

So which one is the best? Excluding that w7.

seems to be a large misunderstanding about what ohms are.

first, speakers dont have a fixed resistance as far as dynamic use is concerned, its a 2D non-linear impedance and i can tell you that the DCR is vastly different than the dynamic load that an amplifier will see. This depends on the fixed DCR (ohms) the system alignment and box volume, the temperate of the voice coil (longer term use progresses towards higher resistance as a function of current over time) this also depends on the inductance of the driver which is a function of frequency and the inductive coupling of the active voice coil with the motor mass(inductive core) itself etc etc....

bottom line.... this is WAY more than you need to know, but i can tell you, dont worry about matching an amp to a woofer, there is not such thing. There is also no such thing as a 4 or 2 or 1 ohm subwoofer. Get over it, and buy the right subwoofer for the right job. That JL is probably the best sub up there. Its 2.5 dcr so make sure you r amp can do 2 ohm load and you're good...

the same stuff above applies for amps... there is no such thing as a 2 or 4 ohm amp either! The JL audio is going to want a maximum of probably ~70 volts. so that means at your impedance minimum (a specific frequency) make sure the amp can do at least 2 ohms at that voltage. Its very simple. If you're confused always buy more power than you need... the voltage is mapped to your volume knob so when people say "keep the gains low"

That also goes for making assessments about woofers based on RMS ratings... manufactures will fabricate that bs to sell woofers and the joke is, there is no such thing an RMS for subwoofers. You want 1000 watt RMS sub... no such thing, because these things are non-linear functions. They are not discrete magical numbers. Its just not proper, even if its industry standard. It does you no benefit to rate woofers that way.

RMS is a much more appropriate spec for amps and that also depends on the resistive load which then will depend on frequency. bottom line..... just give up and kill yourself, lol.

i was kidding about the last sentence.

JLs are overrated.

Out of all these choices, the RE was highest on my tests.

Also, out of my tests, 3 other subs scored even higher than the RE.

JL tested very low. One of the lowest on my tests.

My testes were for SPL output, frequency response, accuracy, durability, and efficiency.

I am using the subs that scored the highest.

care to elaborate on the subs at the top? thanks.

Actually i think you should kill yourself....and leave....now! Your an idiot trying to sound smart and your not fooling anyone.

"you're"

its a contraction of two words...

just a little FYI

Good luck!

i bet your testes were for spl output //content.invisioncic.com/y282845/emoticons/rolleyes.gif.c1fef805e9d1464d377451cd5bc18bfb.gif.....all aboard the short bus!!! //content.invisioncic.com/y282845/emoticons/biggrin.gif.d71a5d36fcbab170f2364c9f2e3946cb.gif

but seriously, it's impossible to say "JLs are overrated", when you're not comparing a select JL Audio woofer vs a certain RE Audio sub. (or at least you didn't describe it like that)

 

[MrDave 10+ year member]

Or, get two 10" subs.

I like how at the end of that you say "its very simple".
70volts @ 14.4 volts is almost exactly 1000 watts. But god forbid anyone actually say 1000 watts, because speakers are a reactive load? If we cant use nominal impedance for anything, how can we conclude a single power rating to even begin trying to match components?

you could buy my 2 12" DC Audio lvl 4s and you would be more than happy!//content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif

dude i have a 12" RE SX with about 925 wrms going to it daily in a 2.5 cubes box tuned to 33 and it sounds pretty good and gets LOUD (atleast in my ears. coming from 2 12" CVRs in a prefab +600 watts lol)

Thats my vote.

 

[blazinb2000 10+ year member]

I love my image dynamics id10v3 so I can only imagine how great an idmax would sound. Also might want to add a fi q to the list if it hasn't already been mentioned.

 

[02accord 10+ year member]

I didn't get to read through all of this but did you state a budget?

 

[Kyle_Keating 10+ year member]

70volts @ 14.4 volts

amperes i'm guessing.....

you really can't... that's my point. its all a more or less an approximation.

you want a good amp for a W7........

Lab Gruppen PLM 10000Q

give me 45 more seconds of caring about this thread, and i might come up with a more efficient/appropriate (cost-wise) solution

 

[Parker G 10+ year member]

it's been 45 seconds. lol

 

[notw 10+ year member]

Woah... I just woke up and there are two pages of replies. Caraudio forums are the BEST by far. Thanks.

[02accord]Said:

Under $600

[scott15]Said:

i had a D2 SX and it was awesome, I've only heard good things about the IDMAX

either way you should be happy

I can't find anything bad about the IDMAX either.

I did notice on several videos of the IDMAX that the rubber surrounding was crimping at high output levels though. Maybe it is the light materials Image Dynamics boasts about using... Seems like after a while those crimps would start to wear no matter what type of rubber used.

Yeah and that RE SX is fairly cheap from ebay. $234.99 Shipped

And Kyle_Keating... I dropped my dual 4ohm sub to 2ohms with my last 4ohms stable amplifier and granted the thing was louder and didn't cut off, it did get hot enough to fry and egg. I think it matters.

I really am interested in SQ more than SPL but I would like a combo of both. Does anyone know more about the IDMAX? Ohyeah! I saw a VERY easy rebuild kit for the IDMAX.. That alone makes me want to buy that sub. Here is the vid http://youtube.com/watch?v=uCl4s9LpY-g.

bonesninja doesn't %100 profit seem like WAY to much? Or maybe you know of a place that sells them for a reasonable price compared to the dealer cost. If so please lemme know bro. RIME

Thanks,
