Could second as a DI and/or preamp too.

The Walkabout is rated at 165W into 8 ohms. I would guess that that would give about 118B with the Faital Pro driver. I will model; it soon but I am up to my ears at the moment.

Call it latency or propagation delay, the Dawson's one quotes 15Ms so twice as long as the Smooth-hound. I have been playing a Smoothound for over a year and never felt an issue. On Thursday, on a dark stage I had to bypass my pedal board that included Smoothound and plug in directly as I lost sound.* Playing with a cable did not sound noticeably different in a band setting. Someone mentioned the latency when plugging into a DAW? Why would you not go direct into the A to D input to the DAW? * I had disconnected a power supply cable when I trod on it. My fault, it should have been tucked out of the way.

The reason you use s resistive load is to take power factor out of the equation.

But how may watts RMS was the Sharpie?

The only way to test and amp is into a resistive load and quote the continuous power (RMA amps x RMS voltage). That give s Average watts. Sadly some use RMS Watts. If you audition an amp or speaker it has to be against another amp/cab in the same room at the same time as our ears have no memory. You may still get it wrong though as the room is a major component of your sound.

One of the things we did was spend hours and hours bracing the cabinet so as to remove resonances. Resonances colour the sound and waste energy. The only composite cabinets I have seen that are anywher neare a` properly damped wood cab are the old Ramsa WS-A200/500 series ( the ones the elephant stood on in the adverts if anyone remembers). However they are not light.

It is not stupid but not all powered PA cabs are created equal. Many have appalling cabinet resonances and suffer badly from the sort of marketing hype (in terms or power specs) that Behringer are often slated for. The fact is that it costs a lot to get a really good FRFR system and even the one that Stevie has been working on is expensive in terms of labour (if you had to pay yourself). Also the recommended driver (because of its weight) i has changed to a new Faital Pro Neo PR320 is approx £130 currently.

The weight at 13Kg is really light. It does not quite get to Barefaced levels but it is not far away. To get lowered weihht we would have the use thinner play and then the bracing and complexity of the design are a real issue. You would not believe the amount of work,especially by Stevie, that has gone into this.design. I am still using the Beyma Version and that comes in at about 14.5Kg I will be fitting a Faital Pro PR320 soon.

The one thing about the BF cabs is their light weight and I find that I would rather have a lightweight cab in one hand and a small amp in the other than a heavier combo in one hand. Of course I am lazt and use a small folding sack barrowlike THIS. Even more helpful is some bungees.

Just silly

I wonder if any amp that needs an idiots guide is worth while? Not being argumentative, just wondering.

Never assume anything when it comes to speakers. You will have lots of suggestions but you do need to try them. Also don'y rule out the Tonehammer, that is supposed to have a dialled in sound and it may be that that is throwing you off. If you can do bit of DIY, then the BassChat 1x12 MK2 may be the right one for you.

Have you got one or two ports?

Might be I will chek it for you later.

Is it the 1x15 version?

There are a few on here that can do that but you would have to post details. Driver model(s) used. Internal cabinet dimensions Port details if any. Tour design goals (what are you trying to achieve in a speaker cab) It won't take long for someone to give you an answer.

As AGEDHORSE points out in a later post, I got my maths wrong as both peak voltage and current are 1.414 times greater than their RMS values. Thersfore PEAK Power is almost twice "RMS". I have left the rest of the post intact but in the table below, Peak power should be 1414W and peak to peak 2827W all rounded to the nearest whole number. Peak of a sine wave is 1.414 x RMS and Peak to Peak is 2 x Peak. So can we believe that the Veyron is 707 Watts. Are Uli's boys playing tricks on us? Well yes to both and it is the slight of hand that causes the problem. However as has been said already, it is a loud amp and is really good value. I have read most of the guff online about power and Rod Elliott has, as usual summed it up well on his site http://sound.whsites.net/power.htm Incidently you will see a term Average power used on some HiFi sites and although not wrong, it is as wrong as RMS watts or RMS power. It should be just power but many, me included, like to say RMS to ensure that people know I am talking about the RMS voltage X the RMS Current. Of course then you have the issue of distortion. If you quote a 10% figure it will still be inflated. I am happy for 1% figure to be quoted on a bass amp although I would like better than 0.1% for HiFi

That is because AFAIK most used standard circuits. Marshall, Sound City et all used the old Mullard amplifier designs manual.

If the FULL power is 880 watts then best case would be 85% efficiency and that means about 750 watts for a class D amp and Switch Mode Power Supply. However if either power amp or power supply is linear then that would drop to sub 70% or 600 watts max of whatever type GK quote.

It ain;t love at first sight though. Attractive it is not.

Air moves out out rapidly from a tuned port as the back of my leg can testify. A hole in the cab could be a tuned port bit it is unlikely to work that we as the port length is only a few mm

Many have used the 10% distortion figure as their claimed out put as Some class D amps are rated that way. IcePower and Powersofet ERTC don't but you can still use slight of hand with those. For example the ICEPoer 50ASX2 is capable of 100W int 8ohms and 170W into 4 ohms bridged (BTL). Gallien Krueger use it in their Combos and in the little 200 Head but ICEpower only claim 170W. But then we are all guilty of assuming that a number in an amps mode; number indicates Watts

I I use a small amount of compression annd a bit of drive usually. Tonight I will go with nothing biut a flat amp from a passive bass at open mic and see if I can hack it.

Out of interest this is the the response of my BC1x12 MK2 as measured by Stevie. It does sound better than my HiFi speakers. The frequency response is the lower trace.
