[quote name='spinynorman' timestamp='1344247214' post='1761561'] Internal Memo: From: Manager, UPS Depot, Dublin To: All UPS UK Hi guys. I can't decide which bass to buy. If you see anything interesting going through, divert it over here, only need it for an hour or two. Cheers [/quote] One bass now had a "test gig"!

I think the speaker/instrument cable is more of an issue the opposite way around. I tried using a speaker cable on my bass & it buzzed like a fridge.

Cheers. When I first read about it, I was envisioning a 60w bayonette type pearl bulb in the cab to light up the port ala KB stylee!

Here's a video of the JBL one... http://www.youtube.com/watch?v=OQo_TUhvUzU I was hoping one of them would pop pretty early on!

After reading another post about a chap (AMPEG) who had blown a driver, I thought I'd have a wee read about & came across this... [quote] Some famous US speaker makers (e.g. Bose and JBL) have discovered how to prevent speaker failures and dramatically improve the input power ratings at the same time. Impossible you say? Actually, it is dead easy. All you need to do is fit a low voltage halogen light bulb in series with your woofer - chosen so it has almost no effect at the 1 watt level where efficiency figures (dB per watt) are always measured and quoted but [i]lights up[/i] brightly and limits current flow when the power input is enough to threaten the woofer. This works because the resistance of the filament typically varies by around 1:10 from cold for full brightness, so when hot, the series resistance is high enough to protect the speaker. If higher than rated system power is ever applied, the bulb simply burns out rather than the woofer!!! Using this approach, a 4 inch 20 watt, 2 ohm wide range driver becomes rated at 80 watts in the Bose 101. Similarly, a 6.5 inch, 30 watt, 4 ohm woofer accepts 160 watts of "nominal" input in the JBL Control 5. [[url="http://sound.westhost.com/articles/speaker-failure.html#ref"]3[/url]] Pure genius or a dishonest but cunning dodge? Seems all is fair in a game where reality has been rendered meaningless.[/quote] Anyone know if it works & if so, why don't more cab manufacturers do this?

The speaker's wattage is how much heat it can deal with. Was you playing at the time & how long at what sort of volume? There's every chance the Ampeg cab wasn't getting 300 watts if you wasn't playing at a pretty high volume. I suppose it's a good way to get rid of the weak cab. Onwards & upwards

& check that they're all 9 volt or you might need separate PSUs.

One's got an N, one's got an H & the other doesn't?

[quote name='Skol303' timestamp='1343920499' post='1757373'] ^^ Cheers folks. It's a tricky subject for obvious reasons. In hindsight I should have trodden more carefully. Hopefully no harm done. [/quote] I never read it as offensive, but it is very easy to read things not how they are intended. The Mrs does it all the time with texts!

[quote name='Mr. Foxen' timestamp='1343931876' post='1757581'] Believing what you read on the internet and magazines would be the seriously wrong thing in this case then. [/quote] As read on internet!

If you took the 2 pictures, turned one to be the same as the other & overlapped them, that would show the overall dispersion.

[quote name='Mog' timestamp='1343905577' post='1757057'] This confuses me. Is the only thing that can cause this proximity to the stage floor or is it some new fangled physics I haven't heard about. And isn't an 8x10 just a two pairs of vertically stacked 2x10's? [/quote] It's all to do with the soundwaves of each driver pushing against one another. You'd have the same result if you stacked 4 2x10s in the same config as an 8x10. Here's something from an AV site that explains a bit about surround sound systems. Same logic applies.

[quote name='Big_Stu' timestamp='1343903398' post='1757000'] Hmm, cunning! a ploy to get another 11 pages going on PC or Mac debate? [/quote] I could have gotten away with it too!

[quote name='Big_Stu' timestamp='1343902571' post='1756980'] Oh I dunno, I'm enjoying seeing how many times people can be so egocentric as to be totally capable of missing the entire reason why most of us are on BC. I know some PC geeks who are more socially aware. [/quote] That's usually because they've saw sense & bought a Mac!

[quote name='discreet' timestamp='1343900265' post='1756918'] Quite. I don't worry about dispersion at gigs. I worry about remembering my lines and trying not to look like a tit. [/quote] I gave up on what you worry about & I just accept it.

You're now gonna spend the afternoon looking for a spare to take with you just in case! Sorry, I'll shut up. Have a good gig tonight.

Some good advice posted there. If you're sitting at home, load up a daw or go to a site like Wikiloops.com on your computer, get some drums going through some decent speakers & jam away. You'll soon be taking basslines to the band to write songs around. I did.

[quote name='Mr. Foxen' timestamp='1343897411' post='1756869'] Doing something seriously wrong if you need to replace power valves anally. [/quote] I'm sure you mistyped?

[quote name='Bill Fitzmaurice' timestamp='1343871309' post='1756744'] It would be better. Horizontal dispersion is inversely proportional to the width of the source. By making it narrower dispersion is widened. Of course this makes the head placement a bit of a task. [/quote] You could always use the amp to prop the 4x10 up on.

That would depend on the frequency response of the cab.

[quote name='stingrayPete1977' timestamp='1343853467' post='1756462'] I was going to make a bonfire night joke but decided to resist due to the thread being quite tense as it was, your joke was better anyway. [/quote] Cheers I think one should always keep a sense of humour regardless of the situation. Or does that make me a bit twisted?

[quote name='Musky' timestamp='1343852029' post='1756433'] Weirdly enough I know someone who did that to an Orange 4x12, back when they were considered undesirable old cr@p! [/quote] Are you saying that's changed?

I've got a couple of spud guns for hire. Good powerful ones too.

This discussion is getting rather humorous. I'm at work until 10 & I've got my popcorn.
