Mandoman you clearly feel pretty strongly about this, and that's perfectly OK by me. But it seems pointless argueing the point without setting out to prove it. We can end this argument quite easily!...

Did you notice your cabs gaining any weight when you used this stuff? I ask because the Rhino Ute/Truck liner I used on one of my cabs added 3kg, much to my disappointment. It's indestructible, but...

4 litres = $99, plus last time I looked at this several years ago, you also had to buy a hardener. It's a great idea but at that...

Nope. They do it to prevent standing waves and internal reflections of the frequencies with wavelengths small enough to be fully formed within the cabinet - i.e. the mids and highs. And those are not...

Great post Soundman but how are you imply I'm a guitarist :) I'm a bass player, and that means that clarity is very important. OK not as important as Hi-Fi, but certainly more important that a guitar...

I'm reading between the lines here, but it seems to me the whole point of the exercise is to run the greatest amount of watts possible into the system to help the inefficient speakers. Hence the...

Just a quick update - Two interstate plane trips later and I'm still very happy with these NC earphones. If you're looking for a set of in-ear NC earphones, look no further.

Did you use a glass top as per the one pictured on this website?

Fuzzie, for $8, you could have got an in-line earphone volume control and solved all your problems. I use this one on planes and it's perfect.....

Not sure what you mean, but if you're worried about the crossovers suddenly seeing a different impedance, dont. You're essentially wiring the woofer sections in series. The crossovers themselves are...

In this case this isn't such a big deal but in case anyone reads this and ponders this as a solution to other speaker impedance matching issues, I feel the need to issue a warning.

Yes adding a...

I pulled the trigger on a set of Sony MDR-NC22's. They cost $195 Australian and what a difference!!! These ones actually work well. The seal the ear canal as well as my Sennhieser CX-300's, they...

Hold the phones (pun intended). There's more to the story of the disappointment of the Sony MDR-NC11's.

As stated in my post above, I have a pair of Sennhieser CX-300's which work very well for...

This is by far the best explaination of Truss rod adjustment you'll find anywhere on the net. Is it then any surprise it was written by...

OK they've arrived and I've quite disapointed. Scratch the Sony MDR-NC11's off your list. There's no noise cancellation at all. All the Noise cancelling feature does is add hiss. The noise cancelling...

Les Paul isn't just a guitar. It's name of the guitarist who invented that guitar. He had a problem with a broken arm that didn't heal properly. Didn't affect his playing though - he was pretty darn...

Hang on a sec, you're in the USA? That should give you plenty more makes and models to chose from. I pointed you towards those because they were either available in Australia, or sold by companies...

Well the air force guys use a combination of passive filtering (i.e normal foam earplugs) and Active filtering (noise cancelling headphones).

The best way to replicate this and still be able to...

For workshop use, I totally agree. For planes or sitations where there's a low of low frequency noise, traditional earplugs don't cut it. That's where active noise cancelling works best ie <200Hz....

I agree with pretty much everything you said. But in this bit, you didn't account for the effect of multiple horns cabs used in conjunction. If you line up several ported subs, they get louder, but...

Is this version better? :)

Agreed! Which explains why a large percentage of guitar and bass cabs contain 2 or 4 speakers mounted in the worst possible position for maximum comb filtering. Placing speakers horizontally was a...

lol... soundman is right, that thing is vibrating. That's a massive loss of acoustic power.........

Trouble is, you'd be amazed at how many commercially made pro-sound cabs can be made to walk...

You're talking to a guy who's home theatre sub is a sealed 2x10 and who's bass guitar rig is a ported 2x12, both of which I designed/built myself, and both of which kick ass...........

Yeah Bill's...

I bought a set of the Jaycar noise cancelling headphones for a recent trip to Thailand. They worked a treat. I usually get off planes with a splitting head ache but not this time. Audio sound quality...

What you really want is a "Bill Fitzmaurice" coffee table sub. It's a true folded horn and a true sub. He sells you the designs and detailed plans, you build them yourself, then finish it in whatever...

I was involved in a rather large experiment which started at a Bass Player's forum I'm assiciated with. Someone was claiming their power cables could improve the sound of ANY piece of audio...

Thanks for the neat suggestion Rod. It made me go and stare at the wall for a few minutes and think about the best option. To be honest, I can't convince myself I'll be able to get the skim coat...

Ok we finally got around to removing some of the mirror tiles, but not from the bedroom as mentioned in my first post. We decided instead to use the small 2m x 1m section of mirror tiles in the...

Sorry to re-hash an old thread. I've just bought a house and am considering buying an alarm system from Jaycar and installing it myself. I was thinking about something like this :-

Thanks guys, some good tips there. I'll let you know how it goes. We're not moving in until late May 06 so if anyone has any other tips in the meantime, feel free to throw them at me.

My girlfriend and I just bought a house, so you're going to see me on here a lot over the coming months. The good news is the place has a double garage which will be my very own 6mx6m workshop. The...

OK it's finished. Check out the thread at:-

The finished product in position. You can see the matching Sub and one of the satellites in the background. As you can see, it was all designed to match the TV cabinet.

Here's a pic with the electronics added.

There seems to be a few of you interested in building speakers, so I though I'd share my latest project with you.

The original plan started a couple of years ago.... to buy a cheap 5.1 surround...

Yep that's what I ended up doing.

+1, It works great for capacitors, and on inductors wound on to plactic spools. But I learned the hard way not to use it on metal inductors, especially heavy ones. The metal conducts the heat too...

I've got one of the GMC table saws. It's OK. It cuts wood. But the gate is pretty much unusable. I only use the table saw sans-gate to cut big planks of ply down to managable sizes, then use other...

I was going to dig up the T/s data and do some maths as the the ideal enclosure size and porting. I did some hunting around for some hard specs on the JV60's. Apparently they use two Vifa P17...

I'm going to have to invest in a digital camera. The trusty SLR is great, but it's not practical in this day and age.

Most of my speaker are designed for bass guitarists but as it happens, I'm...

Yep those loudspeaker programes are a must. I like WINisd for beginners. All of them use the Thiele-Small parameters I mentioned earlier as a basis for their modeling, and all of them make...

It's impossible to do without writing an entire textbook :)

Seriously though, I'm more than happy to answer questions, either in the forum's on via the PM feature.

Greenie the cab's look nice. If I may, I'd like to comment a little on the speaker design. I apologise in advance if you've already accounted for these things:-

As you know, cab size an porting...

Trav as someone who has been designing loudspeakers for several years, I don't see any problems with your original plan. You say the speakers are front ported so that pretty much eliminates my...

Is one of those enclosure types "Bandpass"? If pure SPL is the most important factor, a bandpass cabinet if deasigned correctly exhibit increased efficiency compared to a vented or sealed cab....

Bump! Any follow-up on this Dylan? Did you end up buying a panbrake?
