Digital Designs Sub questions

[TiidaBanton]

Goodday Tunerland

So payday is fast approaching lol and i will be buying a DD510 10" sub for my car after reading all the reviews both online and trinituner. I have a couple questions however;

1. what enclosure should i use?-i checked the dd box specs online and it worked out that those boxes are tuned to about 40hz. Is that too high? i Listen to alot of hiphop/rap and dancehall and i like low rumbling bass.

2.- how does one break in a sub? I am seeing all kinds of crap ie. Its a myth, play a sine wave, hit it with full gain, "free air" it. No straightforward answer

thanks

ur going to get comments from ppl who have never ever owned nor worked with any DD sub , some ppl will post about they hear this & that 1 or from ah padna & from xyz in carshow blah blah

also u will see ppl posting & pming ay doh buy DD : buy my lame brand etc

if u are thinking of buying it from me all u have to do is come into my store & i will explain everything to u & advise u accordingly

u will also get to listen to demos b4 u buy , then i will like u to come back here & reply what u heard from "40hz boxes" .....

Well its from you self i buying it lol but wanted to hear what the masses had to say cuz all i have right now is youtube vids and google to go on. But dont worry i definitely want to see what 300w(all i have for bass) does in a full size DD spec box.

Those dd s is good to throw away , plays loud tho, but not lasting quality , they ain't all that good at 29 hz , look at another speakers fs that gives you a idea on how low they play

[kavaninho]

And then there was this one time, this one guy, ran this one DD sub and it played 30Hz superb, but this one 29Hz sine wave .........meh

OP the DD 510 is great and can definitely hit low and loud with little power.

u really think if DD couldnt play xyz freqs that americans [& folks worldwide] would be using it to play all their rap & low bass songs , they would be d 1st to make d company close down instead of prospering for over 28yrs , right now being summer in states they almost cant build subs fast enough to supply d demand ...

if u cant get it to do what u want then see what these guys & ask them for some pointers ...

then there are the local experts who know better than the manufacturer

[meccalli]

Sure you'll get lf response from a 40hz tune. When you factor in the car environment, its a different ballgame. That being said, dd's have extremely stiff soft parts allowing major leeway for below tuning. They're designed like that, to soak up the juice to get moving while getting low in smaller enclosures. But again, you cant have it all, you sacrifice efficiency. No matter what sub it is, my mantra, build big, tune low- that's the way i like it.

thanks to this guy for pointing this out . no one has done more test than the manufacturer. True talk and if they are to be placed in a box tuned for 40 hz then they know best . true fact is that they are very loud bass and loud bass is a common high fs above 38 hz . so even if you get a box to go as low as 30 am sure it ain't gonna be doing it for long .Lol to besides true dd is made in the USA .not China .check online . my choice would never to buy a speaker with a stutter for a name ! Buy true brands .review your options .there are better brands that require lower freq box tuning for bass

this guy can't make up his mind . stiff soft parts .Lol which 1?

[meccalli]

You understand what soft parts are in a transducer right? DD's don't have to depend on an enclosure's size parameters and inherent 'air spring' to control cone excursion thanks to that factor as well as a low moving mass and high motor force- thus allowing their subs to perform in situations that would easily bottom out a regular subwoofer, i.e play well below tuning frequency in a vented enclosure past the point of air coupling.

play well below tuning frequency in a vented enclosure past the point of air coupling.

Why on earth would anyone want to do that?

Distortion increases significantly below Fb for any vented alignment.

haha this guy will go to any length to prove he is right .lolz is he working for the company ? Am asking myself !

what you laughing at?

Most does be baffled by your level of illiteracy in here.

Exactly, you won't see me go vented and be stingy on space while relying on the woofers ability to handle free air below tuning. Most people I guess interpret that muddy distortion as 'heavy bass'.
I know people who go against a manufacturer are usually crucified by fans but here's DD's philosophy, an excerpt from the support page in regards to enclosure design.

"We engineered a high efficiency type of ported box, then set about engineering a speaker to optimize the box energy. We keep the moving mass low, energy high and add a suspension with high restoring force to help control cone motion. This means that the subs will not have to rely on the box for their loading."
People don't seem to mind and they do what they're designed for I guess.

.lolz is he working for the company ? Am asking myself !

I wish! DD's do what they have to do, get loud, and people want that, kudos.
Myself... never owned a dd, never considered one, probably never will, always considered myself an underground non mainstream sub type of guy lol.

I don't use them personally, I use the Boston Acoustics Subs. However I have done a couple of installs with many different series in the DD line and I can confidently say that they were impressive.

They do play highs and lows and yes the enclosures on their website are tuned around 40Hz but you don't have to be restricted by those designs as the subs are pretty flexible..

As for proper breaking out I would recommend around 40 Hours of play at low volume and increasing moderately as you go..providing all your gains etc are set correctly..these subs are very stiff brand new and you don't want to pop a coil....good luck.
