Hi Grey, I'd like to say Welcome back! I hope this won't be your only post.

There are always people who rub us the wrong way, I find it best to just avoid them if possible, and where not possible to allow time to cool down before posting I don't know the back story, but I think you know as well as I do, why certain things said privately need to remain private. There have at times in the past been threads for actively discussing moderation of the site, at the moment that is not the case. Feel free to raise any issues via the report post button though.

I'm sure you know what a balancing act effective moderation is. I hope you can put behind you any history and become an asset to diyAudio once more. I know I'm mentioning moderation in this reply, but if you wish to discuss it further please PM me as this thread is not an appropriate place for that discussion

Tony.

If you want to decide that the front loading is causing less excursion of the
diaphragm and thus less output on the rear, that would be OK with me.
The asymmetry is the most important feature, agreed, but improved efficiency wouldn't be bad.

It took me two days to convince myself it was worth entering the fray. After posting, it took about 20 minutes with a saber saw to bring into existence a small, single driver example. The SPL meter and my ears confirm it is a very effective mechanical crossover at about 800 Hz. It sounds just okay, but without the baffle to hide the rear of the driver it is a full range speaker.

my brain hurts....
slot volume vs driver area* Frequency range and I'm assuming ~1 to 400hz* avg excursion. BTW I like the single sided driver slot as you could use a wall or floor as one side of the slot. I can see dollars flying out the window for drivers as I visualize a slot sub woofer/open baffle mid-low tweet/ with some kind of super tweeter... can you say 6 channel amp with active crossover.

It's also nice to have some color commentary even if the color is grey...


regards, E

When the impedance goes down the efficiency does not go up.

Some modern stadium line arrays use it in different guises.
