ID OEM's.. not impressed

[Phlipbak 10+ year member]

Well.. put in my ID OEM's and got all my issues resolved pretty much... got 'em running off 120-130 watts, and.. they aren't as loud as my ED mids were off 100w.. wtf..

more power maybe?

Nope, distort in the midbass with 150+. Tried it.

And even so,

120-130 on massive 6.5" mid as compared to 90-100 on a passive crossed 6.5" by ED... was expecting it to be much louder.

Loudness is all about efficiency and power handling...normally raw drivers are less efficient than what you find in standard passive comp sets.

Well that would make sense then, thank you //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif

If the ID mids are less efficient than the eD's you're used to, they'll never be louder off the same power...now since the ID's can handle a good deal of power, that's where they make up for their lower efficiency, and it's also what causes their lower efficiency(more power handling requires a bigger coil, which adds more moving mass, which lowers efficiency).

Of course, this is assuming the ID is less efficient, which I have no idea if it is or not.

I had 200 watts per mid when I was running my ID OEMS and they loved every bit of it and stayed crystal clear the whole time. I also had my doors heavily deadened.

Ya, but they obviously can't handle TOO much since they distort on midbass...

What did you have them crossed at? what were your EQ settings? My setup is crossed and Parametric EQ'd like so..

LOW: Freq: 80 hz Slope: 12 db Level: 0

MID-L: Freq: 80 hz Slope: 12 db Level: 0

MID-H: Freq: 3.2khz Slope: 24db Level: 0

HIGH: Freq: 3.2khz Slope: 24db Level: 0

Band 1: 50 hz Level: 0 Q: 1

Band 2: 125 hz Level: -1 Q: 1.5

Band 3: 400 hz Level: 0 Q: 1.5

Band 4: 1 khz Level: +3 Q: 3

Band 5: 3.2 khz Level: +4 Q: 1.5

How do you know it's not from a clipped signal? What amp are you using? Are all of your EQ settings set to flat? If you have anything boosted then your amp could very easily send a clipped signal to the speakers, causing that distorted sound.

I always set everything to flat...nothing boosted whatsoever. Then, if something is too prominent, you attentuate it. DO NOT boost what is lacking, especially if you routinely run your amp near it's full output.

I'm pretty sure the OEM's are 91db efficient (can't remember how that was measured though).

I doubt it's at 1w/1m...either way, with proper amplification and EQing they should be able to scream.

I suspect a clipped signal. There are so many OEM users pushing well over 150w (up to 300 I believe) and have all positive remarks about how they handle power.

Yea, I'm pretty sure it was at 2.83v.

But my gains are set with DMM to about 120w on a 1khz 0db tone... there isn't a huge diff. in 120-130w and 150w

I had some id cx64 on 2 channels of my pcx4125 which is 125w @ 4ohm 12v and they could have taken more. They are some beefy *** 6.5's
