[quote name='spongebob' post='443998' date='Mar 24 2009, 05:28 PM']TBH, I've always found my Trace to have a fine amount of power for me.[/quote] 150W into two 6"s will be far quieter than 150W into one 15". Alex

[quote name='AM1' post='443701' date='Mar 24 2009, 12:56 PM']Haha, doesn't that depend on the singer turning up? I'll get mi coat.[/quote] Curiously whenever our bass player turns up so does our singer. Alex P.S. Our drummer (not the one with the tempo issues) has started doing back vocals too - it's awesome!

[quote name='Twigman' post='443624' date='Mar 24 2009, 12:10 PM']and the fretting hand?[/quote] When you lighten up with the plucking hand you can then lighten up with the fretting hand too - it takes less effort to hold down a string that's being softly plucked rather than being ripped off the bass. And once you get the hang of moderating your typical attack you can then vary your dynamics much more. Alex

[quote name='Stylon Pilson' post='443475' date='Mar 24 2009, 09:53 AM']I think that often, drummers are so focussed on their drumming that they forget there's a song going on around them. In fact, I think the same can probably be said of any instrument, it's just that the effects are most noticeable when the drummer does it.[/quote] Yep, total nightmare if they're not into the song. This is particularly bad with straight ahead rock music where the drummer is essentially playing identical beats from one song to the next. Teach them the lyrics, get them to sing along in their head. The results are almost magical. Alex

Turn your amp up, pluck less hard. Alex

You've only just bought it. Learn how to get the best out of it before you start adding/changing things. Alex

Logos are here and the first one has been fitted - looks best near the bottom of the grill, centred left to right. Will take some measurements and then get kits sent out to all current owners! Alex

With our previous drummer who often struggled with tempos the solution was to get him to focus on the lyrics - if the lyrics feel like they're going by at the right speed then so the song is running at the right tempo. Once he had them in his head then he usually ended up pretty dead on. Alex

[quote name='Marcus' post='443096' date='Mar 23 2009, 08:59 PM']would I lose any nearfield sound by having driver with a longer throw ?[/quote] This is a very common and totally logical misconception - however 'longer throw' refers to the linear excursion abilities of the driver, i.e. how far back and forth the cone can move, not to how it 'throws' the sound. Often longer throw drivers have less midrange than shorter throw drivers (though this is not the case in the latest designs) and thus the lack of midrange causes you to think the sound is developing further away (due to boundary reflection and off-axis response issues). Fortunately there are no loudspeakers that exhibit 'long throw' characteristics in the sense of 'throwing the sound' so it develops at a distance, though some PA speakers are referred to as long throw because they are more directional and thus should be used when the audience is a large distance away (or else those up close and to the sides won't hear the sound properly).

[quote name='Beedster' post='442209' date='Mar 23 2009, 09:01 AM']Thanks Alex, crap question I know, but would you describe the the extra 3db as significant in the majority of situations?[/quote] Depends! Try adding that amount of boost/cut to your current cab to get an idea of the effect (your EQ is +/- 12dB). Alex

The 151HF is about 50% bigger in volume so I'd expect about 3dB more bottom. Alex

Someone on talkbass changed the stock drivers for DeltaLite II 2512s which can handle a lot more bottom and have much stronger mids. However such a swap would completely change the tone of the cabs. There aren't any decent 4 ohm bass guitar suitable 12"s that I know of. Also there are no 'fullrange' 12"s that can come close to handling all the power your DB750 can deliver in the bottom into the current 4 ohm load. Alex

[quote name='Marcus' post='442188' date='Mar 23 2009, 08:16 AM']I purchased some mega expensive Shure ones like £150 VAT free at the airport when I was flying to Dublin once, thought they were pretty poor so got a refund..... tried all of the different foam & rubber bungs and they just sounded thin and lifeless to me....[/quote] Yep, that's consistent with the iPod's headphone amp limitations - plug it into a high impedance load and the response is flat but plug it into a low impedance load that demands current delivery as any headphones do and it suffers serious sag in the lows. The solution is headphones that would sound far too bassy when driven by a decent headphone amp - so any expensive headphones with near-flat response will sound really thin on the bottom. Alex

[quote name='Delberthot' post='441287' date='Mar 21 2009, 08:18 PM']One thing I can't work out though is that my cab is quoted as being 800w - but these are 250w drivers.[/quote] Specs are certainly creative things... Alex

Looks like an Eminence DeltaLite II 2512. Alex

[quote name='chris_b' post='441148' date='Mar 21 2009, 04:42 PM']I've seen reviews reporting that an amp running at 4 ohms can put out a fuller tone than when it's running at 8 ohms. If that is the case then there could be benefits other than volume when using a 4 ohm cab.[/quote] I've seen similar comments but none of them make any sense. Impedance is nowhere near constant, varying hugely across the frequency range. Here's a plot for a car sub - a ported nominal 4 ohm bass cab would have a similar plot though the twin resonant peaks would about an octave higher and would probably peak at an even higher impedance due to the typical driver characteristics: An amp that sounds fuller into a 4 ohm load would surely sound thinner around the resonant peaks where impedance goes so far above nominal? Also the B&O class D modules in most of the new micro-amps may put out more power according to their ratings into a 4 ohm load than an 8 ohm load but in sustained power tests these modules can deliver about twice as much power into 8 ohms as into 4 ohms because into the lower impedance load they run into lack of current supply and overheating problems more quickly.

[quote name='Chris V.' post='441069' date='Mar 21 2009, 01:46 PM']Let's say I get one of these new Epifani amps and in my bedroom I have the switch set to 8 ohms but when I need more watts at a gig I switch it to 4 ohms - would I be louder or not?[/quote] That depends on whether or not your amp could push your cab to full excursion at 8 ohms, which takes less than 150W with a typical premium neo 12" (like the OEM DeltaLite II used by Epifani) and less than 75W with the same breed of neo 10"s. So there would be a useful difference with a 300W @ 8 ohm, 500W @ 4 ohm head into a DIST 6x10". Smaller cab or bigger amp and the only advantage is psychological. Alex

[quote name='lemmywinks' post='440438' date='Mar 20 2009, 04:30 PM']what's the point in downsizing if you're gonna take 2 rigs?[/quote] Indeed! Alex

[quote name='noisedude' post='440284' date='Mar 20 2009, 01:51 PM']I was thinking more along the lines of a 12+tweeter because this Zoot really brings the combo alive with the tweeter on about a third. I know Alex Claber would kill me for making such a generalisation though.[/quote] Honestly, am I that bad? (Yeah, they say that cat is a bad mother... shut yo mouth!) What's wrong with the Zoot then? Alex

[quote name='Stylon Pilson' post='440208' date='Mar 20 2009, 12:29 PM']New here?[/quote] What happens when you increase Mms? Does switching voice coil change BL and thus Qes and sensitivity? Etc etc. Alex

[quote name='dave_bass5' post='440205' date='Mar 20 2009, 12:27 PM']Im not after more volume as such but more breathing space for the notes, especially the lower ones if that makes any sense.[/quote] My gut feeling is that would be trying to get something out that your cabs don't want to give. Alex

The AccuSwitch was indeed complete BS - it used a large capacitor to isolate one woofer from DC so a DC resistance meter would read both woofers for 4 ohms or just one woofer for 8 ohms. Didn't actually make any difference at all to the impedance between 20Hz and 20kHz. I gather the Epifani solution uses dual voice coils to achieve the switchable impedance so it actually works but it's solving a problem that only exists in people's minds and the solution introduces a whole host of other issues which are far too boring to go into on a bass forum! Alex

[quote name='dave_bass5' post='440175' date='Mar 20 2009, 12:02 PM']Im not thinking of getting one of these as when i tried the SD800 out last year i didnt quite like the tone compared to my SA450 and LMII. I did find the SD800 had a bit more headroom though, certainly on the lower notes. Also it seemed to have a quicker response but not quite as warm. Also i dont need the extra volume although i am thinking of getting a LMIII800, maybe, mainly for the extra headroom i hope it will have and alos the minor updates.[/quote] The LMIII800 has the same power amp as the SD800 and as the preamps are near identical that's where the difference in tone lies. The extra headroom will be pointless, your cab can't do anything with that power. There, saved you ££££££! Alex
