[Who has ran a level 3 in 1.25 cubes?]

DC Subs all like smaller enclosures. I ran 2 12" XL's on about 1.35 cubes, and they sounded great.

I'm not exactly sure why you would ask a question, where the answer is on the manufacturers website, get responses trying to help, and then complain about the help they were trying to give you.

Seems like doing a little reading would've been a better bet. Or better yet, test enclosures. You say you're good with ports, so go build a couple of test enclosures and figure it out.

I know keep it on topic, my bad.

Let us know what you find out though after your test enclosures.

I appreciated him trying to help me but he wasn't offering any insight as to WHY these subs perform better in smaller enclosures. Sorry to come across as a dick. It was one of those days, my bad.

Here is the reply I got back

"Through our testing, our 12" speakers work best in 1.25 cubes to 1.5 cubes. The TS parameters of the speakers can be attributed to this, but the long story short- it is what they like.

As far as SQ/IN of port area, I recommend the typical 15-18sq/in of port, per cube for a slot port. For an aero, you can go slightly less than that, such as 12-15sq/in per cube."

[Who has ran a level 3 in 1.25 cubes?]

Its not the only 12 that recommends that small, all the lower end f.i till the sp4 i think take 1.2 ...

I'm seeing 1.8-2.5 for their recommendation

[Who has ran a level 3 in 1.25 cubes?]

Man, I'm not trying to be an ass here, I promise!

But you are about to ask the manufacturer if that size works well, when they recommended it in the first place. What exactly are you expecting them to tell you? If you want to know how good they sound in a particular size enclosure then you HAVE to consider the port, other wise the comparison is pointless. I'm just trying to help you out here. I can read very well but you are just not considering everything you need to consider.

However, I will stop trying to help, I apologize for taking time to help you.

No I'm asking WHY that size is recommended. WHAT is different about this sub that it supposedly performs best in that size enclosure. I'm not asking what size is recommended but more of the why.

[Who has ran a level 3 in 1.25 cubes?]

DC recommends 1.25. What's the confusion then?

The heck bro? Can you read lol. That's very small for a ported 12. Look at my post RIGHT ABOVE YOURS and you'll see the confusion.

[Who has ran a level 3 in 1.25 cubes?]

I would ask dc and see if they can offer insight.

Most helpful reply in this thread. Not sure why I didn't think of that. I shot them an email and I'll post what they said here, in case anyone else is curious.

[Who has ran a level 3 in 1.25 cubes?]

Bro. Dude. My man. You've replied 5 times to this thread and haven't offered any type of insight or information pertaining to the topic.

Im not asking about ports. I know very much about ports.

I'm not asking about vehicle types. Im aware different vehicles sound different.

I'm asking about a particular 12" sub in a 1.25 cubic foot enclosure. That is much smaller than what other 12" subs perform well in. Is 1.25 really the best size for this sub? Why do they recommend this size? What is it about this sub that makes them recommend that size of an enclosure?

Nothing about ports. You've replied to my questions with other questions.

[Who has ran a level 3 in 1.25 cubes?]

Yes and I want to ask them how they sounded

[Who has ran a level 3 in 1.25 cubes?]

Well let's stick to the topic at hand. Who has ran a level 3 in 1.25 cubes?

[Who has ran a level 3 in 1.25 cubes?]

I usually try to stay between 9 and 12 inches per square foot with aero ports. Do these subs require more port area?

[Who has ran a level 3 in 1.25 cubes?]

I'll be running two of these subs so either a single 6" aero, two 4" aeros, or a slot port

[Who has ran a level 3 in 1.25 cubes?]

Just as the title says. Has anyone ran a DC level 3 12" in 1.25 cubes net? Seems small for a 12" sub but that's what DC recommends for them

Got it thanks guys!

[DD-1 with Pioneer?]

I usually had my lpf on the headunit set to either 60 or 80hz depending if I was running an amp to the mids and highs.

I was talking about the LPF on the amp. Does it matter what the LPF is set at on the amp when you are setting your gains with a DD-1?

[DD-1 with Pioneer?]

Okay cool thank you for the help. What about the LPF setting on the amp? Do I set the gain with the LPF all the way up, and then lower it once the gain is set?

[DD-1 with Pioneer?]

Lol sorry. It's a Pioneer deh 7600

[DD-1 with Pioneer?]

But there is a subwoofer setting that goes from -24 to +6

[DD-1 with Pioneer?]

When using the DD-1 to set the gain on a sub amp, should the sub level on a pioneer headunit be at +6 to get the full voltage from the headunit? Also, should I have my LPF at the max setting on the amp when setting the gain?
