Have you tested it yet? What's your thoughts on it?

Hi, the build pics have me sort of confused (which is easy to do haha). Is this your design or the Cubo? How will you get the driver out once the box is sealed up?

I noticed the updated MBP-46, haha, told you its easy to confuse me!

Hahaha! Yes, it's the MBH-46

I have tested it, but I had to give it alot of power.. And then I mean ALOT.

Any idea what I can do to get impressed?

Are the measurments exactly to the plans? As I see the port is repositioned!

Also what crossover points are you using? I run mine from 40hz-150hz!

How much power is a lot cuz mine don't need much to get them going! Hope the port reposition hasn't caused any phase issues but that may be unlikly!

On a second look at the pic is there a port there or is it just a hole? Can't tell very well but that's what it looks like.

You need to put the port in exactly as the plans say or the tuning will be off and result in phase problems (no bass) and a broken driver!

Yes, its exactly to the plans.

yeah, a little bit repositioned, and I forgot the last piece!! So it's just a hole.. It's that the prob?

I ran them on allmost 3kw with power in 8ohms, and still the old, big son of a bitch sub Yorkville ES808 played better, haha...

Read my last post as I edited it , yes its a big problem mate ! It means its not tune which will result in no bass and a broken driver!

Put the port in and try againg , then see if it beats the Yorkville? smiley15
