  1. Grilles can rattle for a variety of reasons. Ideally, you need to pinpoint the exact location of the vibration. The most likely source of the problem is around the edge of the grille where it's attached to the supporting batten. The screws could be vibrating against the grille, in which case @alexjbassist's solution would work. It's also possible that the foam strip beneath the grille has disintegrated or isn't damping the grille effectively. You would then need to replace the foam strip. 2mm thick should do the job.

    Your best bet would probably be to tilt the combo back to point it at your ears, that gives you 'more-me' but won't change things too much for the audience or the rest of your band.

     

    This is an important point that's generally neglected. The reason you need to point a cab at your ears is because the cone drivers used in bass cabs beam at mid/high frequencies, above about 1kHz or so. So, unless your cab is a constant-directivy design (like a proper PA), you'll only hear those crucial frequencies when your head is directly in front of the cab. Most tweeters fitted to bass cabs don't help either because they don't produce much below 5kHz and the cheap bullet tweeters normally used also squirt the sound forwards in a tight beam.

     

    So,  tilting a cab might help the player standing directly in front of it (just don't move to the side) but, in those instances when the bass isn't going through the PA, it actually makes it worse for the audience because the mid/high freqencies are now being squirted at the roof.

     

    Taller cabs or cabs on stands are easier for the player to hear, of course, as their ears are closer to the drivers. But even then, unless you have a constant directivity design cab, your audience is still going to hear the indistinct, muffled sound that is typical of the bands I hear playing in small venues around here. The solution is a cab that's been designed to be used on the ground and that delivers the same sound to the player as to the audience by crossing over to a midrange driver or HF horn before the beaming becomes a problem.

  3. The peak is unlikely to be a function of the steel basket. If that is the only subsdtantial difference, which seems to be the case, I would expect the frequency response to be the same.I wonder how reliable the published curves are.

  4. I'd expect the higher Le driver to have a longer coil (all other things being equal) but the spec sheets claim the coil lengths are the same. The specs seem to be identical otherwise - so I'd expect the Le values to be the same. One major difference I noticed, however, is that the pressed steel chassis has an undesirable resonance between 3 and 5kHz that is not present in the cast chassis version. For that reason alone, the more expensive driver would be worth it to me - if the published curves are accurate, that is. Another thing you're getting with the cast chassis driver is spring-loaded terminals, which are much nicer and more reliable than the push-on type.

  5. That's a workshop and instrument hire operation rather than a retailer. Also, they operate by appointment only.

     

    This place looks interesting: https://www.geigenbau-winterling.de/.

     

    They build, restore and repair. They have a large selection of antique, old and new double basses and stringed instruments, including, for example, 300 bows. Note that they are only open on two days in the week unless you make an appointment: Thursdays from 2 to 6.30pm and Fridays from 10 to 6.30pm. They have a single page in English, which is here: https://www.geigenbau-winterling.de/service/-english-

  6. On the other hand, there are plenty of reviews saying it's fantastic. There was a video on YouTube about setting levels to minimise the noise but I can't find it any more. It could be that some units are noisier than others.

  7. If I were in the OP's position, I'd concentrate initially of sorting out the cab. At the amp shootout at the last SW Bass Bash, we tested and compared a range of low powered mini-heads through an LFSys Monaco. At one point, one of the amps was driven into clipping to see how loud it would go. There's no doubt that they all produced an SPL that was more than enough for your average pub/club gig. So I wouldn't worry too much about the amp at this stage, although it's always nice to have more power on tap.

     

    "The sound is very muddy and lacks definition (and that's when I'm able to hear myself in the mix)."

     

    I'm afraid that's what cheap cabs sound like. To get to a low price point, manufacturers specify drivers with small magnets and small voice coils, which distort easily and tend to produce a one-note bass. If you buy a second one, you'll still have a muddy, undefined sound - but louder. You might be able to hear your self a bit better by virtue of the fact that the second cab is closer to your ears.

     

    As @Dan Dare advises, you need to try out some more cabs. Don't rely on forum recommendations. If money's tight, go for a used 15" cab made by a decent brand. Fifteens have fallen out of favour nowadays and can be picked up for very little money. A decent fifteen will do the job for you. As far as hearing yourself is concerned, try turning the midrange control up on your amp, or tilt the cab so that it's directed towards you.

  8. For me, hi-fi is a sound that reproduces the bass accurately and without colouration. As @Dood says, it's probably easier to define it by what it isn't than what it is. Most bass heads can do hi-fi well or reasonably well. I've used Markbass, TC Electronics, Ashdown, Behringer Veyron, Aguilar Tonehammer, various Trace Elliot - even a cheapo Behringer Ultra BX4500, as well as power amps and preamps. They all did hi-fi.

     

    The weak link in the hi-fi chain, whether you're talking home hi-fi or hi-fi bass, is always the speakers.

  9. I see nobody's put their head above the parapet yet.😁

     

    I'm fairly sure the differences between these cabs would be more evident in person or if an ominidirectional mic had been used. The sound from directly in front of a cab is only a small part of the story. Anyway, here goes nothing. Bear in mind I don't think I've ever heard any of these cabs in person before.

     

    The numbering of the actual sound files is hidden. On my PC, they go from top left to right, with C2 and C1 from left to right underneath.

     

    C5. Upper mid and higher frequencies absent. Uneven in the lower registers, with some notes louder than others. Some boom. My least favourite. I'm guessing this is the TKS.

    C4. Good definition. Balanced frequency response but lacking some top end. Lows well controlled, although slight tendency to boom. A good quality cab. Guessing Genz Benz.

    C3. Mids and HF present. Balanced with well controlled low end. I think I'm hearing plastic cab colouration here. So I'm guessing this is the QSC. No obvious shortcomings otherwise, and nice top end.

    C2. Uneven, with some notes louder than others. Nice mids but let down by the lower end, which is a bit uncontrolled. On the positive side, it's got a punchy sound with good HF extension. It's a sound I'm sure lots of players will like. Guessing TC RS210.

    C1. Balanced sound, warm and powerful with good mids and highs. Slight bloom on some notes but lower frequencies well controlled. This was my favourite. I'd guess this is the Aguilar.

    I use a Tecamp Puma 900 with a 100W BC micro cab for open mic nights. No problems.

     

    Question for you: would you be happy to let one of the open night punters play through that rig?

  11. Very nice review,

     

    I had the opportunity to hear @Merton's Trace at the SE Bass Bash. It was very impressive from a sound quality point of view. It's difficult to be categorical about these things when there are so may variables in play, but I would definitely be looking more closely at this amp - if it weren't for the price. As the TE1200 is basically a Peavey in Trace Elliot livery (or am I being unfair?), @Chienmortbb's question is an interesting one, because similar bass amps with a Peavey badge on the front are are available for half the price.

  12. Don't overthink this, @warwickhunt A proper, scientifically acceptable comparison requires a much more stringent approach than anything suggested so far. Unless you have a degree in acoustics and an in-depth knowledge of statistics, just make recordings that are as close to what you would expect to hear as a player. Otherwise, there will always be some smart Alec quick to point out the failings in your procedure.

     

    If I were doing this, I'd record each cab in the same position in the room - not too far from the back wall. I'd raise the mic to ear level, i.e. not directly in front of the speakers. I wouldn't bother with close mic'ing at all (but that's up to you), as it's not going to tell you anything useful. If you're using a recording as your source, a hi-fi amp, if you have one, would likely be a better choice than a bass amp. Probably a step too far, but a high quality full-range recording makes it much easier to discern differences/shortcomings in speakers than bass guitar on its own.

     

    Ignore the complications of multiple drivers and different impedances. Just provide the information with each recording at let us, the listeners, deal with it. Keep it simple. Remember what Voltaire said about getting your knickers in a twist.

  13. Nearfield recording isn't a great idea because you won't fully capture the contribution of the port and the tweeter. I'd suggest putting the mic about two metres away. Bill's suggestion of placing the test object in the same place in the room is sensible. Recording at ear height could be interesting, as could recording with the cabs turned facing 45 degrees from the mic - but let's not overcomplicated what sounds like a fun project.

     

    In a perfect testing scenario, amplifier power would be adjusted to account for the different cab impedances. But there again, a 2x12 is going to sound louder than a 1x12 even if the impedance is the same. I'm looking forward to this. It's just a shame you don'f have an LFSys cab in the line up. 😁
