Build it ported and you can always plug it and try it sealed.    Nothing ventured nothing gained. 

I hate to disagree with you Mr. Haskins, but I think it would be easier to build it sealed and try it for awhile. If it doesn't wind your watch, you can then add ports. Just design the enclosure with ports calculated in, the typical ESB is pretty generous and forgiving when it comes to internal volume and it wouldn't hurt a sealed unit either.
Personally, I'd do a sealed unit as I think they really sound better although some of the modelling programs might lead you to think that it wouldn't.

Best Regards,

Yes; maybe its best to size it for a sealed Qt around 0.7, say 500 litres 18 cubic feet.
18 cubic feet doesn’t give maximise the EBS extension, but it still yields an f3 of 13.6 Hz . . 

But I think it’ll be much easier to put ports in during construction.

If three ports are used, that gives four tuning steps below 20 Hz from EBS to sealed . .

This is the point where you should be finishing all your head scratching and just build it.     You will scratch all the hair off your head and you will end up looking like me.   

Make a choice and build that sucker.

At least the scratching led to a better plan than the first one plan
I don’t have much hair left to scratch either!   :wink:
(Now to finish a workspace & make some room space)

Thanks for all the advice

I'll agree that this thread is one of the most informative on subwoofers I've read in a long time. I've been a fan of EBS for some time, not just for subwoofers, but full-range speakers as well. After reading this thread however, I am almost tempted to try sealed again! :)

I will say that I tried my Dayton Quatro sealed for a few days after listening to it's 11Hz tuning for years, and I felt like there was something missing on certain soundtracks, and definitely on frequency sweeps below 20Hz.

If I went sealed, how would I have the cool looking ports?? Here's the EBS Quatro, followed by recent pictures as I converted to the Tempest-X (now tuned to about 12Hz). With a tuning that low, the vented box will handle considerably more power above 10Hz.

Ok... that is the coolest looking sub I've seen Aaron.  If it was in my house though it would end up filled with Hot Wheels.    :lol:

Yes, with the top firing wide open ports, I can forsee a problem with kids. :) I have only had to rescue a couple action figures from subwoofers at work. I think it was a little plastic alien.  :green: I've thought of putting a grill over the vents. Here's a picture with the grill over the woofer. I need to do a little routing to get it to fit over the Tempest-X's large rubber ring, but no biggie.

I think you've created a new alignment: the deep sub as personal art  :thumb:  :green: :thumb:

I think you need to turn that grill into this...



At least that is the first thing that came to my mind when I saw your last photo and the skull next to it.

Hey, that's a great idea! Looks like there a bunch on eBay for cheap, perfect. That saves me a bunch of work. Thanks!
