Big Bass Ob

In some earlier threads I've mentioned this. Now I finally got them. Some pictures for sharing:

Front, for 3 x 18" woofers, overall about 1.2m wide by 1.1m high.

Braces on the back:

Trial fit with Oris 150 mid horn:

With drivers, two Eminence Sigma Pro18, and one EV DL18W:

Overall view (without mid-high):

53" TV looks so small in between these monsters. And this tiny living room is also way too small, oh well...

I'll need some more time and effort to get them work. To be continued....

awesome,

question:

why is it that your horn covers part of your woofers?

CLS · 21st February 2008, 03:20 AM

Partly because of the shooting angle, partly because the "suspension" is not completed.

That was just put on the frame, and about several cm below the target position.

The frequency range of those woofers is below 160Hz, and the horn mouth is actually ahead of the woofer cones by almost 1 foot, so I don't worry about a little overlap.

Very cool CLS! That horn makes the 18s look small.

Updates, divers are now all installed.

This is what it looks like from the listening position, which is only 3.3m away:

The back:

Overall view:

It can not sing yet. I'm working on modifying the xover.

These things scare me.
Are you sure the walls will hold?

Scottmoose · 22nd February 2008, 10:45 PM

Nice... but I can't help but think it's not quite big enough.

CLS · 22nd February 2008, 11:35 PM

NurEinTier,

Do you mean the walls of baffles, or the walls of the house?

LOL

No no no, this apartment is really small. I won't bother the neighbors. Well, as possible as I can.....

Hello,

Very cool

Are you going to multi amp those?

How is the bass?

chrismercurio · 22nd February 2008, 11:50 PM

Are you married?

Seriously....those look really cool. They put a smile on my face.

Nice work,

C
