Default where have you been all my life sealed speakers!

I never see us parting I have almost finished putting together my all sealed system. At least I can say I have it somewhere I really like it. 2x 3ways with 8 inch drivers and 2x 8 inch subs, all sealed. When the sound gets you the chills its usually a good indication your personal quest made a move in the right direction. I guess thats what its all about. Where to go next. I decided to add 2 more sealed subs so that I can try one in each corner, and the + configuration. Im guessing the corners might offer better imaging effects because I wire them L and R the stereo is main purpose is music.

I like the sound of sealed too... but I prefer open baffle.

I also like the sound of back horns and ported boxes. But each has it's sonic character. All can be implemented well and give goose bumps. Enjoy!

Sealed for mid-bass, ported for subs when it's time to move some air.

I prefer a good sealed box over ported too (subs and midbass).

The only open baffle I tried was inside auto, but I don't think that's a fair comparison. I am going to build 6.5 vifa midbass and prestige 8 woofer into separately sealed environments within an environment.

From a technical perspective sealed is probably superior because it cause the cones of the drivers to return to point zero faster whereas ported doesn't put extra strain on the cone as it moves back.

funny

nah
if it is superiour it is only because the system only consist of clean predictable air, and no other strange less predictable system playing along

Closed box is a flippin' nightmare on cabinet construction. It does tend to rattle a box most unpleasantly.

But it has "Timing" on the bass. You will tap your feet to the good rythym of closed box.

Reflex is not so good in that respect. There are technical reasons why the higher order bass of reflex introduces delay. The fact is that reflex bass lags the main signal. So your poor little feet get confused.

Plus closed box goes deeper. So if your room acoustics are big and good, you get a good deep sound.

Trouble is, most bass drivers these days are designed for reflex. It's easier to do reflex cheap. A good closed box gets quite elaborate on bracing and damping. Think B&W matrix cabinets for instance.

But I agree, closed box is more satisfying really.

Why are there so many sealed subwoofers available on the market and so few sealed speakers?

Because it is not so easy to build a small reflex-box that is tuned low. One will actually end up with a long an narrow tunnel.
By using specialised drivers (i.e. specilly designed with the appropriate TS parameters) that go low in a small closed-box one will have very low efficiency though, which is then made up by the use of a strong amp.

And don't forget: Some of them just look like closed boxes but they are in fact reflex boxes using passive radiators.

Charles
