Revelation - status of the project (BD-Design)
Hi Bert,
I'm curious about the progress of the Revelation bass system.
The new Hypex Fusions amps looks like an obvious match?
Best Regards,
Kim

No progress... done!

Hypex PSC2.400, Hypex PSC2.400d and of course the Hypex Fusion amps (FA502 or FA252) will work flawlessly with the system.
Cheers,
Bert

Great to see the Revelation is up and running. 
It look a bit different from your drawings by lacking the compartment for the amplifier at the bottom.
I try to get my head around the principle of the bass system.
As I see it its based on the ripole principle by having a very small compression chamber for each driver (the magnet is sticking out of the enclosure).
The area of the vented slots in front of each driver is roughly 1/3 of the drivers effective area. This should speed up the velocity of the air with a factor of 3.
To my understanding the smaller vented slots also act as an acoustic filter - clever move. 
The front area of the slot opening of the loudspeaker itself seems to be quite bigger than the total area of the vented slots for the drivers - roughly a factor of 1.5. Right?
I might be wrong in my way of thinking... I think that the gained speed in velocity of the smaller vented slots for the drivers will be lost in the bigger front slot opening?
If that is true I believe the front slot should have the same total area as the vented slots for the drivers to maintain the gained velocity of air?
BR.

Hi Kim,
A bit late (forgot to answer...)

The picture is made from an 15" version which does not have the space for the amplifer.
To my understanding the smaller vented slots also act as an acoustic filter - clever move.
Still, not steep enough and with DSP not really something to consider as a bonus.
I might be wrong in my way of thinking... I think that the gained speed in velocity of the smaller vented slots for the drivers will be lost in the bigger front slot opening?
It is tapered... and then still, having it small for 2cm length or 20cm length does not really matter.
