2 12in Type-R / Orion 2500D @ 1ohm / 20hz = wtf?

[Excalibur0428 10+ year member]

Well, I just moved up from an Orion 1200D to an Orion 2500D and all I could say was wow except for when I did a 10-80hz test in incraments of 10hz and basically I had the subs moving pretty hard on all frequencies except for 20hz. At 20hz I had to turn the volume from 50 all the way down to about 20 just to get a tone rather than a sound like the cones were about to burst. I'm not willing to try it again at that volume and frequency so if anyone has an answer then that'd be awesome. I'm running two seperate boxes made by TCAB. Both are 2.5cubes at 32hz.

My guess was that there was too much excursion at that frequency?

Would this happen with a BTL, MT, or any other high qualitly SPL sub in a properly sized and tuned box?

Not that I plan on running 20hz daily or anything, but I'm just curious as to what was going on.

Low Pass at roughly 60hz. Not to sure what the high pass is set at, but based on a clock its at 9'oclock and the Intelli Q is at 2 o'clock.

yea my sub does that too when i play really low notes...i have to turn it down because it will make the sub bottom out

Arent the filters supposed to help the sub not bottom out? //content.invisioncic.com/y282845/emoticons/eyebrow.gif.fe2c18d8720fe8c7eaed347b21ea05a5.gif

I guess not in mine because mine was definently trying to hit a 20hz note and I was getting sound with 10hz also, but it did fine with 10hz, but just not 20.

10hz = //content.invisioncic.com/y282845/emoticons/cool.gif.3bcaf8f141236c00f8044d07150e34f7.gif

20hz = //content.invisioncic.com/y282845/emoticons/blackeye.gif.66a1670f5aaf7f406e783a63e3387dc5.gif

lol, asking alot from those type R's to hit 20hz at hi volumes without bottoming out, If they sound great at 32 on up with heavy volume I'd be happy with that //content.invisioncic.com/y282845/emoticons/biggrin.gif.d71a5d36fcbab170f2364c9f2e3946cb.gif

yeah, i'm loving it with the higher notes, but the type-r's had no problem hitting 20hz w/ the 1200D

 

[SHiZNiLTi 10+ year member]

It's just that they are getting soo much more power at 20hz your reaching there max excursion.

thats why i realllly want a 15in or 18in BTL...I love being in my passanger seat while my girlfriend drives and being able to turn around and watch my subs move, but I think watching a BTL or MT would be much more exciting
