I have a question and I am not really to sure. I just bought these speakers for my install on Tuesday. Basically my question is can these speakers be run at 2 ohms safely and if so what’s the average rms of watts they can handle? I bought them from an authorized dealer but in my box there was no info other than they are 4ohms. I tried searching on here and Google and couldn’t find any info. Basically the amp I have does 120x4 @4ohms but it does 170x4@2 ohms so I would prefer for the shop to wire them for 2 ohms if they can be I am really not to sure...any input would be greatly appreciated. Thanks

If its a really good amp you can bridge it at 4 ohm so you will have close to 240x2 at 4ohm. THe diamonds should have no problem as long as you are friendly with the volume.

yeah but i need the other two channels for the rears. I am going to turn the gain down because i think the rms on the rears are only 75watts rms...but they are diamonds 6x9's. but yeah i still need it to run as a 4 channel..thanks though

jpswanberg

the diamonds show your amp a 4ohm load. the only way to change this is to wire 2 pairs of the speakers in series. the diamonds are quite efficient and try them with your present amp. ditch the rear speakers, they will only screw up your front stage. bridge your four channel amp to two channels and run the diamonds with that if you need more power. or, run the diamonds in stereo, bridge two channels and use it for a sub. jps

i already bought the rears lol...is it really gonna throw it off that bad? and yeah i thought the only way to change it was to wire em in series so i dont know about that. and i dont really wanna bridge it.. and if i bridge the amp i think its gonna be too much power for the hex's..but anyways thanks for the advice. ill let u guys know i guess when tuesday comes.

120 watts per side is plenty enough....

dabusabus1

do u have the diamonds ? and if so how many watts per channel do u have?

CivicEx1998

U will get 8ohm if wired in series.
Parrelle will yield 2 ohm.

If u planned to put the rears, u may try to covered up the highs. The highs is what will throw of the front stage. Or have the gain low.

dabusabus1

yeah i planned on leavin the gains real low in the back.

The Hex's are fantastic speakers but, very power hungry. I have the S600s and I am about to install an Arc Audio 2500XXK on them. It will be running them with 270 watts x 2. The way I was told by Arc that it would break down is 135 watts to each mid and around 67 to each tweet. Even with my 2100XXK which was putting out 100 x 2, the Hex's seem like they want more.

damn i didnt know they can handle that much rms..well i guess after my install i will see if i need a better amp

I hope ARC didn't tell you that. If the amp is 2 channel and you are using the passive x-overs, them amp will send the required amount of power to the mid/tweet set. The x-over will then divide up the incoming signal and send the appropriate sound to each speaker (mid and tweet). The amount of power sent to each speaker is dynamic and changes based on the music you are listening. This will change thousands of times in just one song. (x-over point will effect this as well). What I am saying is, in a real world situation, there is really no way to predict how much power will actually be delivered to each speaker.

theres is no way a 4ohm speaker will play at 2ohm. Yea unless you want to blow them..Just get a decent highpowered 2channel amp that runs at 4ohms.

dabusabus1

i hope 125x4 is good enough lol

AcuraX2

Yes, Arc told me that. The Hex mid is 4 ohm and the tweet 8 ohm. Does it not make sense that if you are sending 270 watts to each channel, the 4 ohm driver will see half, 135, and the 8 ohm half of that, 67. I know it will change with dynamics but, the basic power should still be there right?

bullyx2

Well, with all things being equal (identical drivers receiveing the same information but one being 4 ohm and one being 8 ohm) then yes, that statement is somewhat correct. The 8 ohm driver would see about half the power as the 4 ohm one. If you had 2 mids wired in parellel to the amp (with no x-over) then their statement makes sense.


But in this case, things are not equal. the drivers are completely different and receive entirely different information. Unless you listen to test tones, it still can not be predicted, at max output, what amount of power would go to each driver.

End of the day though, ARC makes phenominal amps and Diamond makes some of the best speakers out there. Too many people get too wrapped up in numbers. You're going to have a sweet setup. I'd say forget the numbers and let your ears decide.

Same thing with the originator, there is no practical way to make an amp see a 2 ohm load with 4 ohm speaker. but no big deal, the 50 watt increase isn;t that dramatic. Have it installed and let your ears be the judge.

CivicEx1998

I guess, thats because the amp is rated 270watts @4ohm, but the ohm load on the components of 4ohm and 8ohm will yield a 6 ohm (Wiring in parellel), so the amp is actually making 270/2 *1.5 = 202.5 watts@6ohms load. Now makes sense that the 4ohm will draws 135watts and the 8ohm will draw half of that power or 67watts.

I have these same Diamonds and love them. I only have 75watts RMS going into them and wish I would of had spent the extra cash on a higher RMS amp. Enjoy them.
