re: Horn Sub Input Please - Build In Progress!

If you put duct take on all those holes around the bends it might work!

I just had to do it!

Looks very well thought out.

What are you going to put over the mouths? You could make a grate similar to those used on hardwood floors. Or if you are up on supplies you could get a steel grate.

Because mid movie, with special effects, T-rex and all one of those mouths might just swallow a chair or two!

I would pay lots of money to watch that.

Yes the plan was to make up a grate to fit in. More worried about losing my kids in there.

re: Horn Sub Input Please - Build In Progress!

Keep in mind that those graceful curves need only be approximated with angled reflectors. In a bass horn an angled reflector is actually preferred over a curve. you don't want to be reproducing midrange frequencies out of a bass horn, and the flat reflectors help to knock them down acting as a natural filter.

And I complement you on the nice compact fold. Nice to see someone thinking in terms different from what is normally offered. The snail folds do not give a person to much room for proper flare expansion. This type of fold will get you a better sound.

Yes agreed on the reflectors. Do you recommend using insulation or sound dampening in the corners and inside the rear chamber?

Hope to get revision 2 drawn up today.

Also thinking again on those flanking subs, I will probably use the dual driver version at the front for the LCR channels and use the single version for the surround channels.

Thought being better transient response and a better match to the sensitivity of the 4pi main speakers

re: Horn Sub Input Please - Build In Progress!

The dual driver configuration can be done with either woofer mounted on both sides of the beginning of the horn. Same as you did for the ULF horn, but on both sides.

As for the Pi speaker keeping up, I'm not so sure. A direct radiator never has the same type of sound.

If you have already purschased the Pi speakers then great. They are pretty good speakers.

If you are going to purchase the Pi's, there are other ways of doing it.

Specifically doing it in a manner that will be much more dynamic.

Depends on your woodworking skills. And the time you have available.

re: Horn Sub Input Please - Build In Progress!

How many channels of your MiniDSP are used in this setup?

re: Horn Sub Input Please - Build In Progress!

DO more complex horns scare you?

No insult intended in the next question.

Do you have the woodworking chops to build cabinets?
