Please comment on this enclosure

BorisH · 3rd April 2005, 07:46 PM

I like this design because it looks good and doesn't offend my other furniture. Internal volume is 5l, height 70 cm (27.6 inches), the baffle is slanted and aims at the listener. Driver's diameter are that of a Seas L12 woofer and a Seas 27* or 25* tweeter. A vent will be placed on the rear side behind the tweeter.

I have another design with the woofer on top here
http://www.audiodiskussion.de/foren/....php?idx=43995

The design with the woofer on top places the tweeter in a more favourable position what edge diffraction is concerned. On the other hand, it moves the tweeter closer to the floor. Still, I tend to prefer the woofer-on-top design as I may tame the early reflections by a carpet.

Concerning phase alignment, there's no difference between the designs. Since the listener is on axis with the drivers, the time-aligned axis is either below or above the listener (unless sitting on the floor).

So, what do you think of this enclosure?

Yeah they are a nice shape etc only thing is all those angles would be annoying

It looks very nice. Now, its sound must be as fine as the unit looks. Have you designed the crossover?

You must do your best to get it.

Congratulations.

Thank you for your comments.

It's the one with the woofer on top.

What do you think of its acoustic properties? I want to use it for John Krutke's Seas L12 system.

OK JK's L12 system has its bafflestep compensation built around the width of the cabinet. If you make sure to keep the baffle width, enclosure volume and port tuning the same then yes it should work well.

Dear Borish:

I agree with 5th element about the sharp corners the front baffle has. You may add some labor making them round.

I do not know anything about the L12 Seas system, are you able to provide some mora data?

I will appreciate it.

Regards

Hugo
