Re: BAD ASS!!! My Sub Box is looking great!

Your speaker boxes look good. It's interesting that you chose Balsa for your boxes. I love innovation like this. Balsa is actually in the hard wood family and when reinforced with fiberglass, is strong as hell.

I have 2 friends that had custom made V-Drive Flatbottom race boats. Both were made entirely of Balsa wood and fiberglass. The bare hulls on these 18' 6" boats weighed only 397 lbs (bare hull = fiberglass &amp; Balsa wood before any hardware installed). When the 427 BBC's were added, they were extremely quick. From years of racing, they never broke...even after flipping a few times at speeds in excess of 100 mph (only stress cracks in the gel coat).

Let us know how your speaker boxes sound when they are done and installed. If you like the results, I may do mine the same way.

Re: BAD ASS!!! My Sub Box is looking great!

Nice job Chris!

....and I know the feeling of wanting to hear them play some BASS!!! The more time you spend on those cabinets, the more you want the 'payoff' of hearing them, and hoping that they sound great!!!

Don't forget to go buy some Polyfill at the local fabric store...It's cheap and you'll want to stuff the box with some before you button everything up for good.

......now I really wish you lived closer! I'm getting excited for you!!!

Re: BAD ASS!!! My Sub Box is looking great!

Greg: yea.....I suspect I will have it all ready in about 14 days. I have the polyfill - I got some from Crutchfield. Question: Should I just lay it inside or glue it around the interior?

I am working on the port today as well as some more sanding and sealing. Saturday will mark the start of exterior laminating. You can not even believe how stong this this is. I can send you part of the cross section I pictured on my webpage if you want to see just how strong this is.

I'll post more updated as I get closer to finishing.

Re: BAD ASS!!! My Sub Box is looking great!

I dont know how much polyfill you got (LBs-wise) but the idea is to "stuff" it into the box. It needs to be somewhat "firmly" packed in so that it doesn't just fall out, but not SO tight that it removes the airspace of the box.... keep it from blocking the port on the inside, and from getting jammed behind the basket of the sub itself. You wouldn't want to keep the speaker from moving!

If I recall, I think I got a reasonable 1.5" Lbs of Polyfill in my 1.0 CuFt boxes. By that logic....somewhere between 3/4 and 1 pound is probably all you should expect to get into yours without overdoing it.

It's not rocket science either, so don't stress out over it. You might even want to play the subs without ANY to get used to how they sound first, and then stuff 'em and listen again. The polyfill is a "fine tuning" process, to get the sound the way you want it.

Also.....The speaker will probably sound pretty bad for the first few hours. Just like an engine, they need to break-in. So play some music at moderate volumes to get the speakers moving. It will "loosen up" mechanically and will start to sound more "relaxed" and it will get "deeper" too. Don't make any final decisions about the quality of the sound for at least 10 - 20 hours of "break in". The speaker will continue to loosen up after that, but the improvements will be very slight.

Re: BAD ASS!!! My Sub Box is looking great!

Chris- I'm going to have to drive down in a couple of weeks to check those things out! I don't have the time, patience or expertise to build some for myself so I'll just have to envy yours!

Greg- I never really thought much about speaker "breakin" but it makes perfect sense. Definately something to keep in mind. Thanks!

Re: BAD ASS!!! My Sub Box is looking great!

Maxq,

A lot of people "assume" that because they aren't EXPERTS, they won't be able to notice things like the sound quality of a speaker changing....

In reality, most people can tell the difference if they focus on the sound and use a piece of music that they're familiar with.....

As the subwoofer breaks-in, it's suspension will get more compliant and it's excursion capaility will increase.....the sonic result is that the sub will start to play DEEPER notes, and will feel like it's not working as hard to produce the notes.....just more of an effortless sound.
