  1. I'm not sure this actually is a small form factor amp - it's 380mm wide. The Peavey Minimax is only 280mm wide and it has two Speakons. The old Ashdown Little Giants were only 200mm wide and they had two Speakons. I'd consider this a minor niggle rather than a deal-breaker. It's certainly good to see another British company active in the market. The more competition the better for us all.
  2. Definitely an interesting head. Cabs not so much. Why only a single Speakon out when the amp can cope with a 2.67 ohm load?
  3. I couldn't agree with you more. I'm trying to get my head round the idea of a pleasing sound that doesn't work live and the picture I'm getting is the Trace smile, with bass and HF lifted and mids cut.
  4. Whilst @alexclaber makes some good points as usual, I think two things are being conflated here. The first is the ability to adjust your sound so that it works well in a band situation. The second is the ability to evaluate a speaker by listening to it. I’m assuming that the “pleasing” sound referred to by @fretmeister is lots of bottom end and no mids(?) because this is the typical live sound of most of the semi-pro bands I’ve listened to over the years. It doesn’t matter what cabinet you give these guys, they’ll always sound the same. Sometimes, the cabinet can make it worse, as there are a few brands out there that make it difficult to get a sound that isn’t muddy and will cut through. However, with a reasonable amount of experience (and as @Muz says, you do need to work on it), you should know what kind sound works for you in your band(s) and how to get it. If you don’t know how to do this, how will you cope when you have to use somebody else’s gear? And if you don’t know how to do this, it doesn’t matter whether you try your new cab with your band, in a shop or in a field. If you do know how to get a band-friendly sound from your gear, however, where you test your new cab shouldn’t make a blind bit of difference. Clearly, for some players on here trying new gear out with their band is important. I understand that. I also understand that it’s a good way to test a speaker’s power handling capabilities. But I don’t find it an ideal environment for evaluating gear personally, especially as venues can differ so much. The most important thing for me when evaluating a possible new cab is an A/B comparison of the potential new purchase with what I’m currently using. Or, if a number of new cabs are in contention, an A/B comparison between them all. You can’t really do that in a gig situation. Still, you pays your money....
  5. Why do so many people think that they can't evaluate a cab unless they use it in a band situation? It seems like a load of tosh to me. In a shop, you can concentrate on the sound and what the speaker is doing, and you can try a variety of things out to see how it responds. In a band situation, you're concentrating on playing with the band. This myth appears to exist only within the bass community. Do you hear violinists, banjo players or drummers saying this? I don't think so.
  6. This is really neat. Thanks!
  7. Your figures are certainly in the ballpark. I checked for 150W using a different program. I'd be tempted to tune to 60 and use a single round port if possible - 69mm drainpipe x 200m long. Perhaps add a couple of extra litres to account for the space the drivers take up. I'd expect this to sound really good.
  8. So this is your sixth? One can't help wondering what happened to the previous five.....😊
  9. The Kappalite 3015 used in the BF Compact works from about 60 litres up. It's probably a better bet than the Faital Pro if your cab is on the small side.The BMS 15N620 works in a 50-litre cab (I had one in an Ashdown Mini 15) and is in a different league to either of those. Unfortunately, it costs more, but it is available in 4 ohms if you can find one.
  10. Before you can figure out whether your replacement driver of choice will work, you need to calculate your cab's internal volume. Faital Pro is a quality brand and the driver you mention is used in a few high-end cabs. However, its parameters tell me that it needs a reasonable volume to perform properly - and combo cabinets tend to be on the small side. My guesstimate is that you'll need at least 70 litres. I should point out that I don't have hands-on experience with that particular driver. There are a few alternatives that function well in a relatively smaller volume, although the ones I'm familiar with are more expensive. Also, if you're going to double the power handling of the driver, you need to make sure that the porting is adequate - or alter it. Bear in mind that you'll likely have to take a jigsaw to the driver opening to accept a slightly larger chassis. You can easily measure that beforehand with reference to the Faital spec sheet.
  11. Overall, a very nice little cab. I compared it with a fairly expensive 12" commercial cab (which shall be nameless) and it sounded much better to my ears, although rather on the lean side. To its credit, it made the 12" cab sound bloated. I think this will surprise people when John's amp is fitted.
  12. To troubleshoot the dip, I measured the cab at 30 degrees off axis. If the dip is caused by reflections from the cabinet sides, the effect will be reduced. The fact that the driver is dead centre in a square baffle will make matters worse. The dip has indeed disappeared on the off-axis measurement, which proves that the cabinet is the source of the problem. This is not something I would worry about personally, as it's very likely to be inaudible.
  13. Finally, the on-axis frequency response curve. It's quite sensitive for an 8" driver - about 94-95dB - and extends up to about 3kHz. There's an ugly dip at 1.5kHz which requires further investigation. It's either a driver fault or it's being induced by the cabinet. I suspect the latter.
  14. Here's the response at low frequencies. -10dB down at 50Hz is quite respectable for this size of box. I've been using the same driver in a larger cab for practice at home for the past few years, and I know it will go lower in a larger cab. Nevertheless, it sounded good on audition, with a lean but tight bottom end that should be easy to fatten up with a touch of eq. Much better that than bloat and boom.
  15. John dropped his cab offwith me a couple of days ago, and I ran a set of measurements on it this morning. It all looks really good. First, the impedance curve. It doesn't reveal any problems and shows a tuning frequency of about 61Hz. I also did a nearfield low frequency measurement, which is more accurate, and that says tuning is at 58Hz. For a very small cab like this, that's fine.
  16. Normally, applying any kind of paint or lacquer to a driver will dampen the top end response, as Phil explains. However, I did measure a blue Ashdown 15" driver a while ago and the top end was all there. So it seems that they (and Sica) know what they're doing.
  17. There's quite a bit of info on this cab on Talkbass. From what I can gather, none of the smaller drivers is sealed; they share the same airspace as the 15. That's not great for the six-inch drivers in particular and might be why so many people on that forum are trying to repair them. To make matters worse, the crossover only works on the horn.
  18. This is a more advanced project than fitting a different driver in an existing box. You're going to have to integrate three different drivers and get them working together seamlessly. Your best bet, as Steve has alluded, is to find out what the existing drivers are, get the spec sheets, and try to locate the nearest modern, neo equivalent. Keep the existing EV crossover (which also might be in need of repair, by the way) and cross your fingers. Unless you're lucky enough to pick some up secondhand, you're looking at a minimum of £400 for new drivers. If it works, you'll not only have a much lighter cab, but it will also handle more power. If it doesn't work, you'll just have to resell your drivers and swallow the loss. Interesting project though.
  19. Check out funkle's build thread here: That's for the CNC cab kit, but the same principles apply if your cutting your own panels.
  20. You'll find the plans and the parts list on page one of the thread, @martyy. Build the cab without the horn and compression driver if you find the electronics a bit daunting. Add them at a later date if you want.
  21. I'd be reluctant to blame Westside without knowing what deal they had with Mesa. As far as I can tell, prices in the rest of Europe were comparable with those in the UK.
  22. Quite probably. 😊 It wouldn't be the first time.
