View Full Version : Will a aero ported enclosure tuned @55Hz hurt lows?

I'm looking at a couple different boxes for my Fi SSD and have pretty much narrowed it down to two. One box is around 3 cubes, has two 4" diameter aero ports 4" long but is tuned to 55Hz. The other is your standard ported enclosure, but only has 1.8 cubes and also comes with some polyfill "sheets" I guess you could say on the inside of the box. Which box is better for an spl design and would give me the best lows? Is there any way i could lower the tuning on the aero ported box? Thanks

You'd be best going off with a custom box design and enclosure. 55 hz tuning will sound terrible.

Both are terrible. 55hz is far too high tuning to play music and that other one doesn't look like a very efficient design at all. Of the two, if you're dead set on this, go with the smaller one because at least you probably won't break your sub.

Could lowe's cut all the MDF for me? The only reason I'm not designing and building my own box is because I don't have a table saw, only a hacksaw

Its sad seeing all those reviews that are 4-5 star on the pre fabs some people just don't know...

No kidding. It looked pretty nice to me until I ran it through my calculator and saw that bs tuning

Yeah they will do all the cutting for you.

those aero ports are alot longer than 4"- look to be about 10" in a box of 17" depth.
i would guess its tuned to 40-42hz

Can they do the circular cuts too?

In that case it tunes around 41Hz... still a little high for me. I just finished designing my own box with 2.5 cubes tuned @33Hz so I'm gonna go ahead and build that. It looks like a much better idea to build my own box anyways lol

yes, building your own box is the best way to go, to me its probably the funnest part of the hobby

I kind of doubt it but i never asked either.

When you put your boxes together do you use glue and screws or just glue and clamp? Also could i use the same caulk used on tiles to seal my box?

You can do just good wood glue, but the cuts have to be perfect, and its very possible they wont be if your getting it cut at lowes. I a personally always screw as well

How hard is it to carpet a box to hide the screws? I just dont like the look of screws lol

If the box is a pretty regular shape its not too hard watch a tutorial and take your time you'll figure it out. Seams are probably the hardest part but youll figure out what works well for you

an easy way to temporarily lower the tuning freq of abox with aero ports is to simply plug one or more ports. this can be tested my shoving a towel in the port, or by using a board with weather stripping to create a tight seal.

All you need to build a box is a skilsaw for the straight cuts, a jigsaw for the round cuts, an a drill for screws, and to poke a hole to start the jigsaw in.

Clamps aren't absolutely necessary, but they help.
