[quote name='civictiger' post='689184' date='Dec 19 2009, 11:35 AM']what would be the more punchier cab?[/quote] Since 'punch' is a purely subjective term one can't say. One also can't predict what any cab will sound like based on driver size alone, this explains why: [url="http://www.eminence.com/resources/data.asp"]http://www.eminence.com/resources/data.asp[/url] Most who combine a 1x15 and 4x10 do so assuming that a 1x15 will go lower than a 4x10. Usually that's not the case, nor will a 1x15 be as loud as a 4x10. The best addition to a 4x10 is another identical 4x10.

[quote name='john_the_bass' post='685184' date='Dec 15 2009, 08:59 AM']Thanks Bill In relation to the below spec sheet (or the snapshot of it here), which of those figures relate RMS power - Music Power or Rated Power? That's what I'm having trouble finding a definition for.[/quote] RMS will be the smallest figure, the one that many manufacturers would prefer not to reveal at all. BTW, that driver will be next to worthless for electric bass, 2mm xmax means it will fart out in the low end with no more than 50 watts input, making the thermal power rating rather moot. I wouldn't consider a driver with less than 4mm xmax. [quote]The trouble you will also have is that it's possible to damage a speaker with a rating of 300w, by only giving it 200w. Your ears would have told you, but underpowering can be just as deadly as overpowering[/quote]Speaking of piffel... Absolutely, positively untrue.

[quote name='john_the_bass' post='685153' date='Dec 15 2009, 08:34 AM']I've been sent a spec sheet for a speaker I have - listed on the spec sheet is a figure for rated power and one for musical power. Sorry to sound like a div, but rated power = peak and musical power = constant? How would that be referred to in terms of RMS power? ie if a cab is marked 300w RMS, what would that relate to? I should listen more I know.[/quote] RMS is real world power, the only figure that should be considered with either speakers or amps. Anything and everything else is marketing piffel.

[quote name='Peter Rand' post='683531' date='Dec 13 2009, 06:17 PM']I won't be running anything at full range. The plan is to send highs to the tens, lows to the fifteens. Anyone else??[/quote] Don't bi-amp. There's not enough difference in the response ranges of the speakers you're using to make it worthwhile. Bi-amping is only of benefit with speakers specifically designed for that purpose, and no electric bass cabs are. Even with a well designed multi-way system with woofer, midrange and possibly tweeters the power demands of electric bass are way too low for bi-amping to be useful.

[quote name='BassBen' post='678000' date='Dec 8 2009, 10:04 AM']I was reading about the Carvin BX500 in the BassPlayer magazine it got a good review. But I hve never owned one or met someone with one. Whats your thoughts? Cheers, Ben[/quote]California is a long way to ship it to if it ever needs warranty service.

[quote name='Moos3h' post='675950' date='Dec 6 2009, 01:14 PM']Nutsacks. That's a pain. Sigh - the search continues.[/quote] You can get 4ohm BP102s here: [url="http://www.speakerhardware.com/legend_bp102_4-SPKBSBP102-4Legend.php"]http://www.speakerhardware.com/legend_bp10...102-4Legend.php[/url] They can't ship outside the US direct to you, but this explains how to get around that problem: [url="http://billfitzmaurice.info/forum/viewtopic.php?f=14&t=9905&sid=7de0486e001ea6e38dd7f5cde25ce01c"]http://billfitzmaurice.info/forum/viewtopi...dd7f5cde25ce01c[/url]

[quote name='Moos3h' post='675931' date='Dec 6 2009, 12:55 PM']Given that 2 x 10 is quite a common setup, why does no-one have any?[/quote]Because the average buyer wants a 4 ohm cab 'so I can get all the watts out of my amp' so few 4 and 16 ohm drivers are produced, and most of those are OEM that you have to buy from the speaker manufacturer, if they'll sell them.

[quote name='jmsjabb' post='675162' date='Dec 5 2009, 01:28 PM']Thanks guys Bill, would you go 4 or 8Ohms for this amp speaker? Thanks[/quote]8, in case you want to add another later.

[quote name='ColinB' post='674954' date='Dec 5 2009, 09:22 AM']Eminence Deltalite II 2512 is a popular drop-in 12" replacement speaker.[/quote] For that application save a few quid, use the Beta 12.

[quote name='warwickhunt' post='670265' date='Nov 30 2009, 01:42 PM']Putting aside what they actually do (or claim to do), I've used them in the past and they can make a dramatic improvement to the tone of certain set-ups BUT if you have a top quality rig then the BBE makes less sense. I'm not being elitist or dismissing the Sonic Maximiser, as I rate them very highly (I presently use a BBE acoustic preamp with SM circuit for my acoustic guitar and it makes a world of difference). 'Lazy EQ'... maybe, but what's wrong with that if it does the job? [/quote]+1. They can make a poor rig sound better, but if anything tend to make a good rig sound worse. Be sure to try it before you buy it.

[quote name='Moos3h' post='669203' date='Nov 29 2009, 11:21 AM']Yep, there's a Little Giant chassis lurking in there when you take it out of the ridiculous amount of metal it sits in.[/quote]I haven't looked inside mine to be sure but I suspect that one could retro-fit an internal fan as well, to duplicate the Little Giant.

[quote name='BigRedX' post='669143' date='Nov 29 2009, 09:52 AM']For me that pretty much defeats the object of having one. The basic unit fits nicely into the "shortboard" pocket of the Line 6 pod gig bag so I can get my complete secondary rig into an easily carryable form, instead of a bulky 6U rack case that my main rig occupies.[/quote] Not at all. Strip off that aluminum crap and you end up with a physical package identical to the Little Giant, and half the weight of what it is now.

[quote name='derrenleepoole' post='668989' date='Nov 29 2009, 06:21 AM']The Superfly is a good head on paper but is let down by overheating issues, grossly overweight for it's size and build quality issues.[/quote] For those who do have them ditch the heavy aluminum outer casing and handle. If that case was properly finned it would weigh a third what it does and would slough heat away, but it isn't finned, so all it accomplishes is to double the weight of the amp and retain heat. Rack mount the innards and put a computer fan in the rack and the heat issues, and the long term damage it causes, disappear.

[quote name='Commando Jack' post='668698' date='Nov 28 2009, 04:00 PM']Hi, I've been looking a new rig, which will be my first giggable rig for small to medium venues. I was initially after a reasonably powerful combo, but since rummaging around on this site, I'm now on the fence about getting separates instead! So it's open season here. A friend of mine recommended [url="http://www.theacademyofsound.co.uk/"]this site[/url], and said he got a 'great' deal on an Ashdown superfly [url="http://www.theacademyofsound.co.uk/Ashdown_Bass_Amplifiers/Ashdown_Superfly_1000_Bass_Guitar_Head_Amplifier"]here.[/url][/quote]I like my Superfly, but I wouldn't pay that price for one. Mine was $199 US two years ago. I wouldn't pay more than that now. If you go for one you'll need two 4 ohm cabs to get the most from it. I'd use a pair of 2x10 or 2x12.

[quote name='harmonicfish' post='665454' date='Nov 25 2009, 01:53 PM']Ok, time to set myself up as a target for ridicule There are a lot of threads in this forum regarding lightweight cabs (indeed there's a whopping great sticky right at the top), but a lot of the time these cabs, although light, are just as bulky as their heavier brethren.[/quote] You've got your Hoffman's Iron Law a bit askew. The rule is low, small, efficient. Pick any two. Weight doesn't enter into the equation. Using lightweight materials, the right construction methods, and long excursion neo drivers you can go low, loud, small and light. The downside is that it won't be as efficient as a larger box, especially one loaded with more than one driver, so you need more amp power. Lightweight materials (12mm plywood) built using the right construction methods and long excursion neo drivers are an expensive combination, too expensive for any of the usual sources to offer them AFAIK. Aside from custom made and DIY Barefaced is likely the only source for cabs of that sort on your side of the pond.

[quote name='ase_one23' post='662905' date='Nov 23 2009, 12:05 PM']would this really make things 'louder' though?[/quote]Yes, by a substantial margin. Put them one atop the other for best results.

[quote name='ashevans09' post='660744' date='Nov 20 2009, 10:22 PM']I've recently been noticing that a couple of bands have taken to pointing their cabs away from the audience, with the backs facing them instead. Now this seems slightly odd to me to say the least - surely you'd want to throw sound out right? And this is on all size venues too. I first noticed it at sonisphere during this performance (nice aguilar rig btw): And also noticed Paramore doing it on smaller indoor venues, bassist included. What is the reason for this? Is it just an aesthetic thing?[/quote] If they're running in ears they don't need to hear the cabs directly, and pointing them backwards would allow them to be run at high levels without interfering with what the audience hears, which is the PA.

[quote name='spinynorman' post='657403' date='Nov 17 2009, 02:37 PM']We're using a Mackie SRM350 as an active monitor for vocals, but the singer often can't hear herself.[/quote] Only one? A monitor per player/singer is the norm, and EQ isn't an option, it's mandatory. If that's all in place and she still can't hear herself: turn the instruments down.

[quote name='fatback' post='655917' date='Nov 16 2009, 08:11 AM']Do amps with DI usually have it post or pre eq? fatback[/quote] Better amps have a switch to choose either.

[quote name='Jigster' post='655219' date='Nov 15 2009, 10:15 AM']okay ta - does any of that go towards explaining why sound guy at my gig last night did a line out connection for my amp? I understand the DI principle but am struggling to see the diff to line out!! [/quote] Line out is unbalanced, which is fine if used to go to a slave power amp that's plugged in to the same AC outlet or power strip as your amp, but can lead to serious ground loop noise when run to a remote device, like a mixer. DI is a balanced send, which eliminates the potential for ground loop noise.

[quote name='gary mac' post='654438' date='Nov 14 2009, 08:22 AM']I know it's tempting to save on lugging stuff about, but I think it's a bad plan Peter. I've seen what happens to stuff in my shed, even when well wrapped.[/quote] +1. And leaving it covered won't discourage thieves. Quite the reverse, they'll break in just to see what you've hidden.

[quote name='Mr. Foxen' post='651246' date='Nov 10 2009, 07:33 PM']I'd hope so. Too much lecturing on the internet and not enough carpentry is that guys problem. See how Bill makes everyone do their own carpentry leaving him free to tell people stuff on the internet. Cunning chap.[/quote] Why spend 14 hours a day in the kitchen cooking when you can make twice as much selling cookbooks?

[quote name='LawrenceH' post='650407' date='Nov 10 2009, 04:56 AM']my limited understanding from t'internet would be that if xmax is reached at 150W LF, then an amp capable of 250w max is about right - it'll drive this speaker to full potential with enough headroom to prevent nasty amp clipping and you shouldn't get near the safety limits of the driver.[/quote]By and large you're fine with an amp that has the same power rating as the thermal rating of the drivers, giving enough power to get the full displacement limited output from the drivers with adequate headroom to keep the sound clean. But some players prefer more grit to their sound and might like to run with less power, especially if tube based, while others may prefer the effortless headroom of an amp with twice the driver rating or more. To each their own.

[quote name='Bass Culture' post='650204' date='Nov 9 2009, 05:41 PM']Okay, I think I've got that. But in practice would it be unlikely that you would put more than 150w into each driver in the low end as the mids and highs would also take a certain amount of the available power too (I've got a horrible feeling this might be a really stupid question now I'm reading it back - but hey!)?[/quote] Power requirements and driver excursion drop by roughly 50% for each octave higher you go.

[quote name='Bass Culture' post='650088' date='Nov 9 2009, 03:58 PM']So the benefit will be in the lower weight of the neo driver but there'd be no performance benefits as such?[/quote]That's about it.[quote]So if I have two cabs with the same driver configuration - i.e. the neo versions - does that mean that my 500w Little Mark will be too powerful for them?[/quote] Not at all, but if you put more than 150w or so into each driver in the low end they won't go any louder, and with enough power they'll distort badly.
