I have a pair of PRO audio speakers with pretty crappy CD's in them I'd like to upgrade. Worth $50 ?

Can't you get a DNA350 for around that?

And I'd be wary of a titanium diaphragm.

I couldn't tell the difference between a 350 and a 360, although it wasn't a direct A/B, it was from long term memory (2-3 weeks), and in a different room.
If there is, it's not directly obvious to me.

Selenium D220Ti seems to get favorable reviews and was the original CD used in the econowaves

Either one of those should handle the same crossover point. I've tested both and might even have two of each sitting around if you wanted them.

Yeah let me know what you have. If it's cheaper than the DNA360 I'd consider that... I need like a 1000hz crossover point though.

I'll check tomorrow. I think the Seleniums are bolt on models. But I can't remember if I bought one polyimide and one titanium or not.

Are you sure you need a 1000hz crossover point? You said you were replacing some cheesy pro audio speakers and I'd be surprised if they were crossed that low. What CD is in them right now?

It's a generic one. 15" two way. Has the screw on waveguide. There is no name on the CD it's all just solid black. It's not very impressive or heavy so I'm guessing it's not good. Either way, I played my electric guitar through these for years so they are hammered and not functioning 100% any longer and need replacement. Woofers seem fine. Atleast with DNA 360 I was thinking I could play around and try it and repurpose those to my theater speakers the DNA 360 at later date, I don't intend to pound on them at all. I'm more juts looking to mess around and learn and experiment with my mini DSP and active crossovers. Wondering what the results would be. Those $99 Crown amps would make a great active cross over amp stack. I bought 2 and already had a spare crown XLS402. I'm set up for two channel active 3 way crossovers. Adding another $99 crown will bring me up 4 way crossovers at some point. This is mostly an experiment so I can gauge the validity of doing an active 4 way crossover on my LCR speakers in my theater. You gotta learn some place right ?

but the crappy CD that the speaker has is probably crossed over at like 2 khz, so the 360 is pointless to put in. Maybe you can try the dna 205 if you really want, but it still isn't going to be good, it's probably way more sensitive than the old CD, so the speakers will be crazy bright without crossover modifications.

No.. it's a low crossover point. I'm sure. And, with the DNA360 I'd repurpose it into my mains at some point. This is as much an experiment as it is a repair.

SO are we saying the 350 vs 360 the only difference is SPL?

They both can crossover at or around 1000hz?

The 350 and 360 were nearly identical. There was a different foam inside the rear chamber and it didn't have gold plated terminals. The 350 cost less, so it was sold for less. But no one bought them because they were "too cheap".

Wow. I have too many projects going on at once other wise I would have bought them a while ago. Maybe coaxials with 350's in the future.?

Nope, they all finally went away with the Cheap Thrills speaker. It was certainly strange that they sat here for so long compared to the 360's when the frequency response was posted on top of the 360 and I told people over and over....they are basically the same.

"Well for $30 more, might as well get the 360."

Audio is a strange industry.

Dave Sheepishly raises hand.

I still say Erich, that the 360 is better than the 350, by ten...

Ok another question, Hopefully I ask it right.

Where is the sweet spot for SQ, output, and safe high power handling ?

I imagine the lower the crossover point the less power handling and higher distortion at high output right ? And you risk damage more likely, so is there an ideal that balances those things ?

Would a DNA 360 play louder crossed over at 1300hz versus say 900hz ?
Or sound better? Or have more output ? Or less likely to be damaged ?


These things matter to me.

The lower you cross, the lower your power handling.

How about sound quality ? Or output ? The same right ?

Would a crossover of 1500hz play cleaner and louder than a 1000hz crossover ?

Power handling doesn't matter as much as distortion and output to me, but they are related right ?

I think it was stated earlier the 360 could easily do 1000hz so 1200hz should be just fine and easily be in its comfort area. As soon as Erich gets some in I am goimg to order a pair of them and see what they sound like crossed at 1000hz. I will most likely settle for a higher XO but will start out as low as I can. I am crossing over to a 10" so 1200hz sounds like a great number for me. I just have to hear what it sounds like first.

Mike, xo and power handling will dictate max output. That is to say, with a lower xo, you'll have to limit max power (and therefore max output).

If you haven't, read through Tux's recent build with the Celestion woofers. He worked out a few different xo designs with different points and slopes, for different goals.

Slope is the missing element to your calculation at this point. The way slope and phase work together is going to have a lot to do with the elegance and natural sound of the result. And of course, slope will in turn have a lot to do with power handling. None of this operates in isolation.
