Lab12 - Tapped Horn -
Thanks to Don Snyder & Chris.
Split off from this long post,
- 2-sheets of 3/4" 15-ply ApplePly used.
- The blue CAT5 will be used to power some RGB LEDs to illuminate the 1/2" Green-Edge CNC Carving / access panel.
- Coil will be installed later
Here are my current build pictures:
Old Canon 10D, 28-135mm USM-IS, ISO100, F16, 1/80sec.
Some CNC V-Bit Carving Action:
Setup took about an hour
Wow, love the pictures and the build quality, very nice!! Although this is build very rugged, you might consider some bracings at large areas, Since I´m in Pro-Sound, I use similar plywood as you do and I´ve always had to add some bracings and it always improved the sound (and made rumble from the enclosure walls less).
Nice work! Please, keep us informed as to the placement of damping materials, and other progress.
Also, would you mind sharing name and number of the driver and CNC panel (elegant) mounting hardware?
what about doubling the number of biscuits?
Really nice work and great pics! I like that the driver is visible. My tapped horn is very similar in layout to yours and I get slick of putting on the hearing protection and sticking on my head in the mouth with a flashlight to monitor driver excursion.
I added a ton of bracing to mine, here's a pic if you're looking for some inspiration.
BTW how to you intend to finish it - i.e. paint, stain etc.
It's great when a plan comes together ...
MaVo did the simulation, Chris8sirhC decided to build the first one, and I did the fold
for Chris. Now, Layertone has built one of the nicest Tapped Horns of this series.
Great job & pics,
Great construction !
How does it perform compared to regular boxed sub's with the same driver ( sealed box ? ) ?
Horn's are great for high efficiency but how does this implementation compare ?
I'm asking because the chance of me coming across a similar setup is 'very' remote .
Impossible to design without computer simulation, and 95% of all drivers are unsuitable.
This one has an F3 of 20Hz, but it can only be used to 70-80 Hz. It requires 4th order HP & X-Over filters
It isn`t very much
grey the same driver with the same inductor in a vented enclosure of the same size (peak at 20 Hz will be lower in reality because of enclosure losses)
Now, lets turn up the power ...
1. What happens when the port chokes?
2. Doesn't the vented box run out of xmax first?
