I own: 12" Eclipse Titanium, is IDMAX 12v2 an upgrade?

[danfortner]

Hey All,

I bought an Eclipse Titanium back in April and installed it in a fairly small sealed enclosure (although calculated/recomended size). I am very satisfied, the SQ and the SPL has been very nice. I also have a pretty good amp, that definately does not underpower it - US Acoustics 1000D - 750w RMS is the full RMS for that sub. It has been working out great.

Sealed sounds good and hits pretty hard, but I just want a little more. Adding another sub would mean that I would be pushing 1500w RMS on my stock alternator and battery, and really I don't want to make that upgrade. So my plans had become this: port the 12" Eclipse Titanium, but do it geared towards SQ still. My attempt would be to make it just as clear and accurate, just louder. This wouldn't even be a big box, I think I came up with 1.5cuft before deplacement, so like 1.7cuft, ported at the hz that I would find after testing the cars resonant frequency.



But then an offer came across my table for a IDMAX 12 D2 v2 - for 225$ shipped. I was wondering what the general consensus is between these 2 subwoofers. Initially it would be in a 1cuft sealed enclosure (maybe I would make a 1.3cuft - which is recommended) and it would be run off of the same amp, except @ 1 ohm. It would recieve 1000w RMS @ 1 ohm and the amp is stable at 1ohm and puts out 1250w. What do you think:

Both sealed, which has the edge in SQ and SPL?
Running the US Acoustics 1000w @ 1 ohm, is it safe?
What if I went ahead with my project and ported them, geared towards loud SQ, which would have the advantage?
Would I be able to tell which would preform better ported by hearing them sealed?

Also, is $225 shipped a good price - aprox 10 months of use, this is v2 not the new v3 (which goes for $319 new, plus shipping).

THANKS A LOT!

background on the 2 subs:

12" Eclipse Titanium 9122 (2003 model)
dual 4-ohm coils
wired paralell for 2-ohms
750w RMS, recieves 750w @ 2ohm from amp

Image Dynamics 12" IDMAX D2 v2 (unknown year, fairly new)
dual 2-ohm coils
wired in paralell for 1-ohm
1000w RMS, would recieve 1000w @ 1 ohm from amp
amp could push 1250w if needed to

Need Qts, Vas, all that? Just ask and I'll post.
THANKS

Post as many T/S parameters as you have on either one if you could.

Tough call... both are relatively Low Q drivers with a similar Fs. They both actually model quite similarly to one another in a nice SQ box... 3 ft^3 tuned to 30 Hz.

If you are looking for louder I would give that to the IDMAX since you will have more power available to it. SQ would be a toss up to personal preference I'd say.

Sealed box wise the difference is minimal again with the IDMax having a little bit more low-end (barely).

If you are happy with your Ti I say keep it, the difference really won't be night and day. Unless you can audition the MAX to see if you prefer it's sound I see no reason to change.

yea... idmax might be louder, but i dont really think its worth upgrading... just port the eclipse

[B&R Innovation2]

Agreed totaly with that...just port the eclispe

[danfortner]

Thanks for reassuring me. I just thought that I had to jump on this deal right away. But could someone punch the numbers for the Titanium, I think that the number I come up with is 1.5 cu ft for a SQ ported enclosure. Sundownz mentioned 3cuft, but I think that was the measurement for the IDMAX 12.

Also is 30hz the prefered tuning frequency for a SQ ported enclosure?

yg PM, but I also say port the ti, and send it more power

[Rookie_80]

how much?

Dude this thread is 4 years old...STOP!
