16" Table Tuba
16" Table Tuba
Here are some pictures from my recent 16" Table Tuba Build. Pretty much followed Bill's instructions. Cut most panels using a panel jig on my table saw as per Bill's design. The panels turned out pretty accurate and after the first few panels I started contructing without screws. I simply glued and clamped.. including the final side. Installed the 8" Dayton recommended driver. Powerred the unit with a vintage Audio Design PA100 MOSFET 100 watt per channel mono bridged power amp. Sounds great!

Re: 16" Table Tuba
Have you tested it out yet? How does it sound? After I get done with my current builds dr's titians and wedgehorns I am going to build one of these. I got lucky and already have a tang band 8" driver that will work in a small ported sub that I build a few years ago.
Re: 16" Table Tuba
It sounds amazing. It has replaced a ported down firing 8" Mission sub. As expected there is a big change in the low end sound. I have no equipment in to make any actual sounds measurements so I am restricted to what I can hear. The home theater now has a solid low end response that is both musical and heart stopping.CraigsAudio wrote:Have you tested it out yet? How does it sound?

The sub is corner loaded behind the seating position. The Yamaha RVX663 receiver choose a crossover of 60Hz and that seems to work as I am getting no locational signals from the sub.
Here's a question:
I have not tried the TT in any but the one spot that I had had the old sub in. (That location was chosen by moving the old sub around the room until I found the spot that gave me a peak in the listening position.) Would you expect the TT to behave in a similar way to the old sub in terms of room nodes? There is one other location in the room that the TT can go but it is where I had previously found was not a good spot for the old sub.

Re: 16" Table Tuba
If it works well, leave it alone. Don't fix what isn't broke. However, I do suggest that you at least try and raise the crossover frequency to at least 80Hz, or higher. I think 60Hz is just too low, especially when the sub will handle the band better than the mains.

Re: 16" Table Tuba
With the rising response of the TT that's about right, unless you've got 4th order filtering.DJPhatman wrote: I think 60Hz is just too low, especially when the sub will handle the band better than the mains.
Re: 16" Table Tuba
Thanks Bill and DJPhatman for your comments. I will bump it up to 80Hz and see how that sounds.Bill Fitzmaurice wrote:With the rising response of the TT that's about right, unless you've got 4th order filtering.DJPhatman wrote: I think 60Hz is just too low, especially when the sub will handle the band better than the mains.
