Hi Everyone,


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!


Cheers,

Joel

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

if $20 x2 is a lot to you, 350, otherwise 360. i'm not being a smartass, that is really about what it comes down to. the comparable de250 is much more in either case.

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.

The cheaper builds will use the 350 and the nicer builds the 360. Where that cut off is I don't know. But if you're extreme one way or the other you could pick which one.

Even though the response curve between the DNA-360 and DE250 are almost identical, is the impedance curve between the two also closely matched if I'm trying to use an existing XO design for the DE250?


Thanks,

Darrell

It's been confirmed you can swap the 360 for the DE250.

I currently use 3 360's in the 4PI's for LCR.

Here is the measured FR of both the 360 and 350 that I have:

Thanks Nasty, the 4PIs are just what I'm planning.

You won't be disappointed.

I just finished the center this weekend, and got a pair of JBL 8340's as surrounds for dirt cheap.

Finally have the 5.0 complete and I'm in audio bliss

interesting. how do you interpret this? would you say the difference is insignificant if crossed over high enough?

 

[Erich H]

If a design uses the DE250, the 360 could be dropped in. It might not have as good of a high end as the 360, but that shouldn't be a big deal.


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):

Would you mind showing the FR on the 205 also?

 

[Erich H]

The 205 actually took longer to nail down than the 360. I had a diaphragm at the beginning that measured very good. It was more expensive but there was a bit of variation between each one. Here's that one in red and the DE10 in black, I believe on a SEOS-12:







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.

 

[Eyleron]


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."

How did the B&C DE10 sound compared to the DNA-360 or DNA-350? Would the DE10 be better than the 360/350 if used as a tweeter only, crossing over to a dedicated mid-range driver? What about using the DE10 versus the 360/350 in a 2 way configuration? Just curious

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.
