The level of bass will change throughout the room. If it is not acceptable you can either move the sub, or move the sitting position. Most people prefer the former...
I like secrets...most of the time. Depends on how much secrets cost though :P
And should the bass change with difference in distance from the ground ?

Re: Maelstrom-X Horn

you are experiencing "boundry gain", same effect you were noticing regarding sub placement. I suppose you could lower your ceiling...

Re: Maelstrom-X Horn

Dylan - very interesting thread. I've thought quite a bit about building a horn and using one of Kevin H's drivers - since I like them so much.

It looks like I underestimated the importance of strong bracing though - after seeing what you've been through. I imagine that there is a good reason for kits like the Danley DTS-10 to have dado cuts for the section... Too bad it's hard to do without CNC!

Nice build Dylan. You may have convinced me to do my own when I get the space.

I have a friend with access to a very large CNC router. I suppose I should get to the begging!

Thank you.

Bracing is definitely a very important part that I missed, quite frankly, with installing the plexiglass where I did. The PVC bracing that I've installed has pretty much taken care of all the rattling/flexing problems, but I am still working on securing the plexiglass to the baffle.

I am extremely happy everyone took their time here to design this horn, and especially thankful that my uncle was willing enough to let me build this in his garage...well he pretty much did all the building

A CNC cut box would be extremely helpful...especially with horn boxes that require tricky angles and things like that.

Just a little update. Got most of the rattles fixed yet again, hopefully going to get it somewhat painted tonight, and round over the edges as well.

I got a short video posted up on YouTube a couple of days ago, here's a link if you want to check it out. Song is B-Legit - Stick Em (extremely slowed down). I think the highest note in the song is around 30hz, and seems like it drops down to around 17hz. Sounds amazing. Lol.

This afternoon, my Uncle brought over his router, we rounded over all the edges, sanded down what was needed, and smoothed out the rounded joints. Looms great, but the pictures aren't showing it very well. Didn't have very much light to work with, so bear with the photos please







The three edges on the mouth are completely round now. It looks amazing, and it super smooth. The last photo makes it look like the far edge is slightly un-even. It doesn't appear to be in person though. If it is, it's small enough to not notice it at all. It's ready for paint now. Hopefully tomorrow I can find some time to throw a few coats of truck bed liner on it and finish it up. Going to get some wold dowels soon as well, to replace the PVC that I have installed at the moment.

Got two coats of paint on the box last night, looks alright so far. The putty used to patch the nail holes is showing through the paint, so I will hold off on more coats until I decide what to do. I think I'm going to sand down the areas that need it, and go buy some roll-on truck bed liner paint instead of the spray can stuff.

Re: Maelstrom-X Horn

Great job Dylan. You need to undercoat the filler, sometimes twice with a light sand between them.
Keep up the good work.

Silence is golden but duct tape is silver.
