I'm having a very difficult time in choosing between the two DNA CD's. I've seen the specs and it looks like they are very similar with the 350 rolling off 1 kHz sooner and starting 50 Hz later as well. They have the same power handling and sensitivities. Is the biggest difference the recommended crossover frequencies? or is there more differences between the two that can't be seen in specs (such as how they sound)?
I will be using these primarily for surrounds, but may in the future use them as two ways. Should I just purchase the 360's and not look back? Any and all feedback is greatly appreciated. Thank you for your help and support!
IIRC, the 360 measures slightly better than the DE250. Doesn't roll off early in the high end. The 350 is a clone of the DE250 in that it measures almost the same. I don't remember for sure if this is correct, you'll want someone else to confirm.
I went with the 360 and didn't look back
Its not only the cost difference. I'm not sure if I'll be able to hear the difference between the two. If the difference is noticeable, I'll definitely go with the 360's. I guess if I knew in advance what all the upcoming designs will use, it would also make it easier to make a decision.
For what its worth, I really enjoy how DE250s sound. I'll be using these DNAs with SEOS-12 as surrounds for now. Unless things change and I get bitten by the upgrade bug again, these may be used as 2-ways in the future if my whole system gets changed around.
It's been confirmed you can swap the 360 for the DE250.
I currently use 3 360's in the 4PI's for LCR.
A crossover built around the 360 was likely designed to take advantage of the extended high end, so the DE250 might not test as good in that speaker design. Or at least you wouldn't get the most out of the speaker.....unless you can't hear that high.
Jeff Bagby has response and distortion tests for the 360 here (post 23 and 27):
After a good amount of testing and changes, I decided it made sense to go with the more consistent diaphragm to keep things pretty much identical between each unit. The new one ended up looking nearly identical to the DE10, except the 205 goes a bit lower (even lower than the example above). But it also has that similar dip around 2khz as you can see in the DE10 above. I think the measurement for the end product is on my laptop though, I'll have to find it. They sound really good and they're used in the Karma-10, Delta Pure, 8" B&C Minion, and the 8" model Jeff Bagby is currently working on.
What are the major differences between DNA-205 and DNA-350?
Distortion, crossover, and power handling, I imagine...but at what point would someone notice in the home?
Pretty much what you said. There probably wouldn't be much difference in a home. But there are benefits to lower crossover points that the designers would have to explain. I personally have the DNA-205 going in my living room and really like the way they sound.
I ordered the Fusion Max because I worried about second guessing the decision if I got the Karma (for the lower x-max, thinking "is there higher distortion with this model than the Delta-10A?"
My limited skills with WinISD seemed to show the woofer reaching x-max at low frequencies like 100hz so I worried about that.
Or with the Fusion Pure "will I regret the DNA-205, since that's lesser than the DNA-350, and at least with Selenium 220 people report harshness?" I couldn't find a DE10 vs DE-250 comparison. I probably shouldn't have suffered in silence and should've just asked.
Mainly what I could find between AVS and DIYSoundGroup is you or Tux or someone saying about a lower crossover something like, "it brings it down in the range where the CD and horn are handling more of the sound, which usually does a better job, unless your CD runs out of steam."
The 8340's make a nice surround and the cabinets are decently constructed. I use a pair of them in my room. Mine were dirt cheap also.
When I say this, I'm talking about the DNA-205. I found the 205 to manage in a two way reaching down to 1450hz. If a lower sensitivity application, maybe even lower. So it can do a mid sized 2way. It measures wickedly smooth on the seos12. The 350/360 just have way more balls, and that matters. So depends where you're crossing. If like you say, to dedicated mids, I'd use the DNA-205 for sure.
Indeed they do! I remember you posted in my thread about patching the foam. I ended up going through with it and they're good as new.
I also followed your SEOS/TD12M build.
How are you enjoying them?
We have a similar setups.... it's always cool to hear what someone thinks.
Thanks for simple advice
