Badmaieff and Davis pub 1966, I've got a copy in front of me, my first speaker book I built a few near copies of the Altec A7 from this and I have a collection of old books from the pre Thiele and Small era. Happy days

Go on give the family a trip to the countryside

The tweeter does so much more, but depending upon how it is implemented. That depends to a certain extent on the crossover used. The Crossover shares the sound out, highs to the tweeter lows to the woofer. It might be wortwhile checking that the crossover is disconnected in your cab, if not it might be stopping the highs reaching your woofers and killing your sound. There is a reason why tweeters have a poor reputation; many older cabs had tweeters added as an afterthought. Frequently they were poor quality and simply added on to an existing design with a simple capacitor to protect the tweeter as a 'crossover' instead of a properly designed system. Worse still many of the add ons were super cheap piezo tweeters which did away with crossovers altogether and in any case didn't have a very flat response. Simply adding high frequencies simply doesn't work well creating lot's of unwanted noises and sharpness whilst messing up the crucial mid range. Bass guitar doesn't really need high frequencies there is nothing there above roughly 6,000Hz depending upon which pickups you use and in any case these frequencies are lost once you are playing within a band, the crucial frequencies are from roughly 80-4,000 Hz, give or take. Speakers with big cones start to beam (narrow the dispersal of sound) when their dimensions get close to the wavelenghts of the sound they are producing, 10" speakers start to beam at around 500Hz and beaming is significant and unpredictable above 2kHz and big heavy cones don't produce high frequencies well anyway. A well designed horn system will fix a lot of problems the small driver will produce cleaner high frequencies and the horn will guide the sound in a predictable fashion so people to the side of the speaker will hear more or less the same sound as people in front of the speaker, That includes the bassist who rarely has the speaker pointing at anything other than their legs.

I must admit that £5 off the Sennheiser and Shure radio gear hardly counts as a discount But, there's a lot of Behringer digital mixers with much bigger discounts of around £100 or more which makes me wonder if behringer are about to upgrade their offerings. Over the years a lot of the Andertons bargains have been end of lines, and I've bought a few bits of bargain kit off them.

I've always loved the look of this @Pea Turgh I'm a lazy so and so when it comes to finish and the corners and handle set it off really nicely reminding me I really should take it more seriously. You've even made the round grille look like it belongs rather than the afterthought it is on my cabs

Sound enginers have sometimes had a bad rap on Basschat but there are some great ones out there too and a good monitor engineer just gives you confidence to play your very best. Here's to Dave and all the others like him 🍾

Yes, I use the same few bits of music to test speakers but a lot of it is classical music which is very demanding of any speaker but not familiar to everyone. I use Western Highway by Maura O'Connell as a test of the midrange, a lovely clean recording of two acoustic guitars and two female vocals that is really revealing of any crosover artefacts. @stevie uses Smooth Operator: Sade which has some nice percussion up-front as his go to. I'm guessing though that a majority of us are playing some form of rock so something well known and well recorded might be better and I'll need CD quality. I've also got some Hi Fi Choice test recordings somewhere.

OK I wanted to do the PA shootout anyway so I'm proposing to do that in the main hall after lunch. I'm going to bring my 15" tops to compare with my 10" tops used with a sub, @Woodinblack is bringing his Evox system, all these are RCF Active systems and roughly in the same price range so its a reasonable comparison of big tops, little tops plus sub and a stick system If I can fit everything in the car I'll bring my old Wharfedale PA so you can see what a cheap old system will do and I can demonstrate the power alleys you get when you have the subs placed under the tops. I'll also attempt another cab build in the side room at some time in the morning demonstating the 'Easy Build' technique and showing off the new BC 8" cab design. I'm happy to take suggestions about what we might add to the PA shootout to help anyone thinking of buying PA gear in the next couple of years. Any suggestions though are welcome.

The problem is pretty well known but I've never seen a band address the problem before and to be fair not very many venues. Full marks to you for thnking of the solution and finding the right product. 6db extra headroom before feedback will make a difference.

Have you ruled out a self build? I designed the basschat 6" cab for precisely this use, it's tiny but has a proper speaker that will handle bass. The bottom end has been sacrificed deliberately but it has a flat response from just below 80Hz all the way up to the highest frequencies from a bass and in a small room it sounds beautufully clear and has plentyof bass if you don't want that rumble that permeates the house. You can use it with your TC If not then another option is to use a studio monitor, I use an RCF Ayra Pro 5, if you want tone shaping then something like a Sansamp or a Zoom B1 four will drive it or your Phil Jones Bighead

That's interesting, I've not come across that before, how do you go about it?

That's it really, Andertons have a sale on with some interesting reductions. A few RCF speakers (RCF 735 for £839) £200 of a couple of A&H Qu mixers, Loads of Behringer stuff cheap including X18 for £399, XR16 for £322, X32 Producer for £999 loads more too. https://www.andertons.co.uk/browse/offers/all-live-pa-offers/?page=2 Does this make me an influencer?

Ooh, bring it to the bass bash

https://www.thomann.co.uk/tc_helicon_voice_tone_d1.htm https://www.thomann.co.uk/tc_helicon_duplicator.htm https://www.thomann.co.uk/tc_helicon_critical_mass.htm this one is not really delay but another way of thickening out the sound I'm looking at these for my own use in my duo where I do the dooby-doo's and it would sound better if there were several bv's. Think Chelsea Dagger. The advantage of pedals is that you can switch them in and out with your feet obv's and your singer can/should buy her own. On another track you might like to look at something like the Mic Mechanic https://www.thomann.co.uk/tc_helicon_mic_mechanic_2.htm . You are right though, a mixer would give more bang for the buck. Given the number of pedals you have...... you'll adapt

Limiting is just controlling the peaks and bringing them down. Compression is looking at more of the sound and squashing it down reducing the difference between the loud and quiet bits. They both work the same way but compression affects pretty much all of the vocal sound depending upon how you set it up. Normally with compression you turn the volume up to compensate for the compression. https://www.sonible.com/blog/compression-vs-limiting/ I ought to say that the poblem with compression in a live setting is that because of the increase in gain you can get feedback problems, not a problem if your singer is loud and doesn't need a lot of ggain but a problem if there are howlround issues. Limiters tend to decrease feedback issues Detuned delay: delay is an echo effect but with often one repeat rather than reverb where the effect decays over time. If you set up a single repeat it sounds like a second voice supporting the first and if you can de-tune it you get a more realistic effect as no two voices are identical, delay without de-tuning sounds a little robotic if overdone. There's a thread on reverb and delay in the PA forum. TC and others make pedals for vocals which can create this effect for you.

I would have thought prety much most interfaces will do this I have a Moukey MSc1 and it sounds great alternatively a lot of small format mixers have USB interfaces built in. I'm using my Alesis mixer at the moment for this evening's practice The ana logue circuitry leaves a bit to be desired but it's good enough for personal practice and recording ideas. Hiopefully you can fix your old one though. Good Luck

I'd say for least financial loss buy something fairly decent and avoid anything that says 'practice amp' The reasoning is this: if you buy something old but good you'll be able to re-sell at more of less the price you pay. On top of that most 'practice amps have terrible speakers and tone. Your novice is going to be discouraged by poor tone and enthusiastic about making lots of lovely bassiness. They'll be even more encouraged if their first amp is good enough to jam along with mates. My first amp was a Hartke Kickback 10, bought for £100, used for four years and sold for £100 and I even gigged with it a few times and used it for dozens of rehearsals. A small gigging combo might be easier to re-sell and be a better bet and it will certainly be nicer to play

So are you proposing to build a cab? im assuming since space generally is an issue and given the capability of the Kappalite that you’d go for a 1x15. Essentially a version of the gen 1 Barefaced Compact. If you aren’t going to build then one of those would probably work well for you.

We will need the internal dimensions of your boot for our calculations 😂

Like you my bass has mainly gone through the PA for years and that is pretty much what the audience usually hears. The best bass sound I ever get is surprisingly through my little RCF 310's up on poles which we use for rehearsal. On the floor the bass is just a bit overwhelming without a lot of eq. but used as stage monitors you can get a good sound with them eq'd. I've also used them singly or as a pair for backline at gigs and it works ok. Nowadays I use in-ears. It can all be done successfully but you need to reset your patches and spend as long on getting it right as you probably have on your TC setup. Like you I feel I have to carry some sort of backline for the odd gig where nothing else is available and I do have an amp and bass cab. I think that's the rule though, There's no voodoo magic in bass speakers or PA speakers and all the rules apply. If you can't get away with a single 10 for a bass cab then a 10" PA cab isn't going to do it either. If cheap bass cabs dont sound as good as expensive ones the same is true of PA cabs. If the cab only sounds it's best after 2 weeks of setting and re-setting your signal processing then expect the same when you switch to FRFR. If the Spectracomp is central to your sound you are going to need a pedal with FRFR. In your case with the BC208 you'd probably need a decent 1x12 FRFR speaker to match the output. Personally I'd look at something a little better than the Headrush or Harley Benton where some savings will have been made in the bass driver, but they'll be fine if you don't push them. The advantge to you of course is that you can then rationalise and use the same speaker for bass and your guitars

Happy to take a look.

I'd love to see your BC 112mk3 cab. It's the only one of the BC designs I don't have.

We've swaped thoughts on PA before Mike and you were one of the West Country people I was thinking of. Maybe we could play with PA speakers in the side room during the day and perhaps do something more organised next year. Let's see what people want once we have a few more comments
