Can I please break a 147?

The octo port was first used in the Toby BP enclosures. It is simply another way of doing a "round" port. You gain more by doing a round port over the "octo port" setup.

So explain the octo ported box a few pages back putting up impressive numbers. It's a pretty small box.

If you're that impressed with it, why this thread? Really I'm not saying there's anything wrong with 45's in the mid 30hz range, but if you want to see bigger numbers on the meter the answers are in this thread.

Let me ask you this, is your peak @ 35hz or 55-60hz? If it's 35, how close are you to x-max at full tilt? If you're not at full excursion a bigger box will help you improve your number at 35hz.

What does your response curve look like? Do you own a meter?

This is the classic "kicker reccomends 3 cube for a 15" square sub" thread, but for DC.

Your subs will sound louder and look more impressive on the meter if you build a bigger box and tune higher. 50$ worth of wood and glue to figure it out for yourself.

That's not my box it's one I'm trying to copy. They are at full excursion around the peak yes. They look like they want to jump out the gap.

I have a 10 month deployment coming up!

But seriously, this car has been a PIA. We are going to try and copy the octo box I posted a few pages ago. That one has a 7.5 inch port. I can only do a 6.75 and get daily tuning. I would be happy with a musical 148. 50 on a burp would be great. That guy did a 49 at the headrest with level 3s and AQ2200. I hope it works for me.

Thank hommie but I don't think that's needed. It has to work, if it needs higher tuning there is enough external to trim off to 40hz.

i dont see a musical sealed 50 unless he switches subs IMO

 

[LosIsATool 5,000+ posts]

It is. Ohm and a half of rise on 60hz. Less in the 35-45 range.

40 was about 1 ohm. But it was still clamping almost rated.
