Dual Loaded Table Tuba by a Teenager

That's quite a good story, glad you didn't get a ticket! (Or whatever they call them there, eg: "cops" for us="billos" for you Aussies)

Its actually an offense in Aus. now to "Cause offensive noise from vehicle / conveyance" there could be a lesson for you BM. Best google your local regulations before you set it off in the Forester

This is sage advice, I read and heed. I tried googling, and the laws in Memphis, at least the ones that I looked at, don't show specific dB levels.

Nice work. I am somewhat worried that the police will be a semi-constant annoyance once the warmer weather comes around here as I intend to throw some garden parties and get a few mates in to DJ.

I think the very first test we did of the two T39s and Omnis was sat in the garage where they were built which is about 20ft from the house and a good 9/10ft from next door. We had them playing and the signal was barely registering on the mixer and they sounded immense, however juuuuuuust at the drop (always is, isn't it?!) we heard the lady from next door screaming over the gate "EXCUSE ME! EXCUSE MEEEE!". We turned it down and the lady explained she lived next door and the bass was causing her TV to vibrate and asked if we could keep it quiet.

After she'd left myself and my friend just looked at each other, both thinking 'holy fuck, what have we created?'.

I hear ya. My back yard faces the State Police Barracks/Warden Service right through the woods there. I can see their building plain as day. Minimal outdoor parties over here. Good crime preventer in my neighborhood though.

I'll probably do a light coat of black, just to cover up all the ugliness of the filled screw holes. Can I use drywall spackle or wood filler for this instead of Bondo?

Why? Just overbuy duratex and sell it back in the sellers forum.

As for the spackle, I have done that on another project. Not so great. Either bondo, or if you need very little spot putty (bondo in a big toothpaste container) should work. Just do it right the first time.

I'm getting a quart of Duratex, which should be more than enough for 2-3 coats. Thanks for the advice about the spackle/bondo.

NP. Actually you can get by with PL too. If you have some left over you may want to try it but the spot putty is pretty cheap anyway.

Just make sure to take it upstairs before you go to demo mode. Your dad may not want to help you take it back out.

I will be able to use PL as long as I sand it down to expose the pores. (I forgot if it's 60 or 40 grit, some grit gets quickly clogged)

I use PL for the screw holes. When sanded the exposed pores in it hold DuraTex just fine.

good plan, or demo outside when nobody important is around. I'm piety sure that thing is capable of putting cracks in drywall if you crank it to the right frequency inside. Seriously.

The cops not having a dB level to enforce means they get to use their own judgement and discretion. They are always right.

Parents warned me that I would have to pay for windows that I broke, but drywall?? Sheesh. As I said awhile ago, this thing will never see full power inside my house. It may see close to full power at small DJ events I sometimes do, but probably only a couple times will it be really pushed in my car, and at that volume I would lose my hearing pretty quickly anyway so only for a little while, wearing ear protection. It's all about the vibrations anyway.

+1 about being always right. I was joking about that, but I don't know how half the young hoodlums in my city aren't broke from noise violation tickets, with their multiple 12's all booming at once. Some guy in a truck pulled up next to me the other day, he must have had a couple of big subs in his truck somewhere, it made my seat vibrate and I wasn't in the car with him!


I'm think I'm going to be genuinely shocked when I fire it up for the first time. There will be two "first time listenings" for me: One when my parents home, barely giving it 10 volts most likely. And one when I'm home alone, cue war volume time and dancing madly with nobody watching.

No progress today, but there will be a marathon of progress tomorrow since I have a good chunk of time in which to build.

Random post update: Another order from Parts Express came today, two pair MTX Monitor 5i bookshelf speakers. These will be side fills for extremely small >50 people garage DJ events like I sometimes do for my friends, and monitors for the bigger events once I build my Otops or SLA pros in the future. Here's my personal music listening setup so far. It's on an anorexic budget (that's why I mix pairs of speakers), and much of the stuff was inherited from my dad, including the Sony STR-D1011 and the pair of old Polk Monitor 4a.




I know this is probably one of the worst ways to arrange speakers on top of one another like that, but I don't have any room to fit the rest. The blue Sony speakers in the middle are my garage rave mains.

It's not much, but I'm happy with what I got, all of them together get pretty loud in my 11' by 12' room. Can't wait to see what the TT does.

Nice Setup Bassmonster 5 drivers either side is guaranteed to give you some punch. My olds would have been all over me like magpies on a chip, if I had a setup like that as a teenager. Seems like you have some pretty understanding olds.

I bet your Dad is almost as excited as you, waiting for their maiden demo. Good luck with the rest of your build

[Gregory East]

Actually, vertically stacking is the best way to arrange them.

When I said break the drywall I was meaning cracking the joints like you had an earthquake or dodgy foundations, or poor building practices. Or too loud subs.

Good luck with that.

Hmmmm, parallel wired driver's, 10V, that'll run aboooot 125dB in your earhole at 8kHz. ( Mum screaming at you to turn it off )

If you can get over 5V before Mum starts having kittens you have a very placid Mum.

[bassmonster]

125dB at 10 volts? B...b...b...ut... I was running 15v on break-in and the gain on the Bash was only turned up 2 or 3 notches! What kind of monster am I building.............


On an update, I've had lots of time to work on it today and Panels 10 and 11 are installed, more to come later tonight.


I had the chance earlier today to flex the muscles on my new speakers with a nice blast of Noisia. All that combined with a small corner loaded sub still managed to make the gutters on the outside of the house rattle a healthy bit (my room is at the corner of the house).
