I like innovation in speaker design.
Probably the latest thing I have seen different is the Forte cabs with the side ports.
That is a neat idea and the reportedly sound great.
I also like how he weight relieves the plywood to keep the weight down.

I like this one!
They are kind of expensive but they are quality.

They have a new kick stand tilt back system.

Re: Why oval ports?
I don't like porting on any axis other than 0. What can sound good in certain spaces folds down to a canceled nightmare through a microphone.
Not what you expect to hear, and you know.. you expect to hear a certain thing that we are used to.

Ever made large holes to wood...?
A rectangular hole requires that you drill about four small holes per each corner of the rectangle and then cut the wood from hole to hole with a handsaw. (The holes are needed for the handsaw's cutter bit). Usually you need to finish things up with a file since the result isn't often perfectly square.
A round hole only requires that you simply drill it with one of those drill bits that looks like a rounded sawplate (I don't know what you call that thing in English). If the hole is very large in diameter you drill one hole and cut the whole thing with a handsaw.
An oval hole requires two such holes and you cut the rest away with a handsaw.
So, it's basically much easier to make round or oval holes to wood than square ones.
In many cases it might also be just an aesthetic issue.

Re: Why oval ports?
As for all these kinds of supposedly "ported" systems...
I wonder how many have ever done the math of them, finding out the wavelenghts vs. cab dimensions and figuring out at which frequencies they actually introduce some filtering or if the ports actually could even operate as ports (moving air mass contained within the port).
Most of these new so called "Tuned Thiele" cabs (the one's that look like twin speaker cabs with one speaker missing) are pretty much equivalent to placing an open back cabinet in near vicinity of a wall behind the rear opening. Nothing "Thiele" or "tuned" in them whatsoever. That 3D sound cab goes to the same category.

... with the exception that the 3-D cabinet should not be as sensitive to how close it is to a back wall.teemuk wrote:Most of these new so called "Tuned Thiele" cabs (the one's that look like twin speaker cabs with one speaker missing) are pretty much equivalent to placing an open back cabinet in near vicinity of a wall behind the rear opening.

Re: Why oval ports?
That's my thought as well.
The Forte sounds similar to a semi open back cabinet but has a sealed back so it shouldn't matter too much how far away the wall is behind it.
Of course with just about every kind of cab there is, you will perceive more bass if a cab is up against a wall or in a corner.
