Any opinions on D-Box 30X subs??? (1 Viewer)

[Mike Veroukis]

Hi there!
I've seen a lot of talk about SVS subs on this forum but I've yet to hear anyone mention the Canadian made subs from D-Box (www.d-box.com). My cousin has one and I have to admit it sounds pretty good. My only concern is that he bought it at Costoc for around $300Cdn. I'm just wondering what people on this forum might think about this sub, how it compares to some of the other more popular subs. so far I think for the money the D-Box seems like a good choice. Any thoughts on their subs or other speakers by D-Box?

I took a closer look at it the other day in Costco. The surround is tiny, which leads me to believe it doesn't have a lot of Xmax (how far the cone can travel linearly). I also measured it's external and port dimensions. From this I calculated the tuning frequency to be around 40hz (way to high for a sub).

I was going to have a friend try it, but after my closer inspection I've decided to go to the trouble of helping him build his own sub using a Dayton DVC 12" driver.

Thanks Brian, glad someone besides my mother cares :p)

Hi Mike nice to see another winnipeger on the forum. I might suggest that you look for the Sony sub that a lot of people have haved about instead of the D-Box. Another option is to build your sub. I can lend a hand in that dept if you're interested.

It is one of the worst sub's I have ever heard. It sounds SOOO BAD! Boomy! Oh yeah, it has no output either.

I'd build my own for a coupla' hundred more.

 

[Dustin B]

If Andrew's willing to help you out Mike, I'd seriously consider taking him up on the offer. He could help you build a Tempest or Dayton DVC15" based sub for $800CDN or less that would be able to take an SVS UltraCS.

Or a Shiva or Dayton DVC12" that would be on par or slightly better than an SVS 20-39PCi for around $500CDN.

If you have some more money than this to spend there are some other options capable of ridiculous output.

PS- I take it you sold your 15"DVC Andrew? What are you going to replace it with?

 

[Mike Veroukis]

Hey guys

Thanks for all the replies. I was just asking out of curiosity as to what people think of this line of subs. I'm not in the market for a sub right now, but I will be eventually.

Building a sub sounds like fun but I know very little about that sort of thing. When the time comes I will be sure to post back here.

Thanks again.

PS- I take it you sold your 15"DVC Andrew? What are you going to replace it with?

Yes it sold last night. Its going to get replaced with a dual tempest IB sub that I'm going to build once we move into the house next week...can't wait to hear it.

 

[Dustin B]

Oh you lucky prick :p)
IB bliss, I'm soo jealous

 

[Andrew Pratt]

Well Thomas keeps saying IB's are where its at so I guess that's where I'm going LOL Let me know if you're ever in Winnipeg

 

[Mike Veroukis]

So, here's a question... What's an IB sub? (gotta learn these things somehow!

[Andrew Pratt]

Mike here's ThomasW's 12 shiva's a dancing IB sub. Mine will "only" use 2 15" tempest drivers.

It's an appreviation for inifinite baffel. You use another room, closet, attic, basement, whatever. The key elements are the area has to completely isolate the front wave from the back wave and both areas should be at least 5 times the combined VAS of all the drivers used.

 

[Mike Veroukis]

Thanks again guys
ThomasW's 12 shiva's sure looks mean! I bet that can shake the house apart.
Dustin, I also looked at your DIY SonoSub. Pretty cool. When ever I get a house to put something like that in I'll be sure to look into this some more!

Anyone know just what amp Thomas is using for the 12 IB subs? Must have some mondo power huh?

 

[Dustin B]

I don't know what the amp is, but I seem to remember him mentioning something about 2kiloW though. Even so, that many drivers he won't need much power to get things thumping. That is one high effieciency design.
