You don’t actually need the crossover (all the boxes you’re looking at have passives, and to put an active in would ideally require you to re-wire and bypass the passives)…

Pretty good for £2K though – don’t forget that at that power, you will need to run it off at least 2 seperate ring mains in your house (assuming you are in the UK and have standard 13amp domestic supply). As a relatively simple calculation for your requirements, take the KW rating of all amps added together, and multiply by 4 (so your prog rating of 6K needs about 24amps of power).

Like the look of those Turbo boxes though – gonna be building something similar for our rig this winter (having discovered my bass drivers are in the process of kicking their way out of their current boxes – if I’m building boxes, I decided I’m gonna be doubling up too….raaa)

Wont realy need 2 seperate mains at the mo coz our rig is only at the 2-3 k mark at the min. Still wondering if u can help. Got this 5kva honda generator and it has 2 230v hook ups does this count as 2 ring mains?

Looks like a kicking little (?) rig you are putting together there man.

Gotta be great value, even assuming you are earning the yankee dollar, rather than taking pounds and converting them, as these are good prices. Might be worth a few UK people looking at them, although shipping would be a few quid.

Good luck with it all out there – we look forward to fantastic party reviews….

BTW – which part of US you gonna be raving?

Righty first of all I can’t stress how important research is.

£2000 is a lot of money and you don’t want to realise at the end of it you’ve bought a load of shit. I would hold off for now as although a few of the things you are talking about are good quality bits of kit, things like those nady’s aren’t worth the chipboard they’re made of.

Running the txd-151’s and those nady’s covering the same frequencies will sound worse than just running the turbos on theiir own as the nady’s contain rubbish quality components and dreaded piezos.

Your subs will do the job not my preferred choice (I don’t tust behringer very much outdoors) but they will do the job. Though you have chosen a double 15″ box to go ontop of the 18″ behringers (I’m assuming) that actually only plays to 40-150hz which is lower than the behringer although you could put them on top but I don’t trust them as they don’t give any sort of freq response diagrammes proving their 40-300hz claims.

I also think you need to look into impedance to understand how your amplifiers will power your speakers as the behringers you’ve suggested wont power any of the stuff you have suggested.

an ep2500 will put out 500w at 8ohms which isn’t enough for the behringers and 2500w at 4 ohms bridged which is a full 900w of headdroom which is usually a bit much for a reflex cab especially if its behringer.

same goes for the turbosounds they need 1200w at 4 ohms. You get about 950w (all these figures are off the top of my head as I own an rmx2450 which is wha behringer ripped off with their ep2500) which won’t do the job and 4 ohms bridged is double the required output.

I would again have to say don’t do it yet. Wait learn and save yourself a load of hassle. Running soundsystems is an expensive hobby. The ammount of money you invest to begin with means nothing if you don’t know how to properly maintain and run it.

it would be two radial circuits (a circuit straight from the power source to the equipment), at 2.5kva each which is about 10amp from each circuit. If you balance the load across both of these outlets everything should work,

The principle behind a ring main is more suited to fixed wiring and thus normally only found in houses, they were something invented in the UK to save copper after World War II (as half the size of cable can be used

As for suffolkravas, he is using all this kit in America where they normally have 110V power but some areas of a house have 220V which is taken across two phases (for big appliances), or larger houses have 3 phase.

If he has access to the sort of space I believe is called a “den” across the pond I would suggest he sets up there and gets a proper electrician to check the power feed out.

Although the rig is way more than most “normal” houses use, lots of Americans have workshops and loads of computers / electronics /studio kit in their den so its not uncommon to provide big power feeds to this part of a house..

ta for that

a crossover would help as then you can controle the frequency range going into yous bass cabinets this is quite usefull sometimes and when you dont need it its also usefull to controle the gains personaly i find a electronic crossover godd for my subs and they sound better with them…other people may disagree tho..but you certainly dont want to start pluging crossovers into full range cabbs unless you just want them to play tops mid or lows.,..should pound tho..but i would still look around and learn a little more befor forking out all that cash even if it is a good deal..raaa :crazy_diz :bounce_fl :bounce_fl :bounce_fl :bounce_fl :bounce_fl

Is everyone missing the fact that none of the kit goes together?

Wrong power ratings of amplifiers and mismatched frequency coverages.

Although I haven’t slept much so I might be making a mistake.

You don’t want to cascade crossovers though (if the speaker box has a passive in it, and you are also using an active in the signal chain, you are wasting a lot of power, along with losing control of the xover point above the frequency the boxes are set to)

As GL says – ring mains are basically fixed install (when I say ring main, I am referring to an individual feed on it’s own circuit breaker – either fuses, or MCB’s depending how old your wiring is. Each circuit should provide 13amps though (in the UK that is – I have no experience of US or continental wirings…))

For the generator, the power should split evenly into the two circuits, and as GL says, should supply about 10amps to each… It will supply power unevenly if you load it unevenly, but try and balance your load as best you can (more due to the fact that most cable runs you’re using are likely either 13 or 16amp rated, and melting cable isnever good…:wink:)

The only other point is wether the genny is diesel or petrol… You can run a rig off a petrol, but I personally never do (petrol genny’s are less even in their power generation, as they generally alter engine speed to cope with increased or decreased load – a diesel puts out the same power irrespective of load, which makes the generated power constant – something that will help extend the life of your rig)….

No, you are right…. (sorry, didn’t look too hard into the specs…. being lazy this morning…:sign0007:)

All I really looked at was the Turbo’s (which are speakers to die for…) The nady’s are a bit of a waste of space – the TXD151’s will cover everything the Nady’s do, and will do it with far more style (they have 1″ compression drivers for the top end – which are more than capable). The TXD215’s will cover more than the Behringer woofer can, and will be far louder/cleaner sounding… You would be better served using the cash from the 18’s and the Nady’s to get another set of TXD’s (or better still, invest it in really good amps like Peavey, or Crown).

Not to say that Behringers aren’t any good (I use a lot of Behringer kit, and much of it is excellent), but the reason they keep prices down is often by using cheaper components – not a problem in many cases, but with power amps it usually is a problem, as the components can be put metaphorically through the wringer – cheaper ones usually pop their clogs at this point, where the more expensive will survive…. Check ebay for power amps – you can get some really good stuff quite cheap, and if you go for something like Peavey, C-audio, Crown, H & H etc, you should be OK (most amp makers realised long ago that the primary characteristic an amp needs is indestructability:wink:).

If you want to use an active crossover (and here, Behringer make an excellent one in the CX3400), you could rewire the TXD151’s so one input speakon goes to the 15, and one goes to the CD horn. Then you can run it 3 way (the 215’s won’t have a xover, as they only have 1 speaker type in each box) – one amp driving the 215’s for bass, send mid to the 15″ drivers in the 151’s on another amp, and high to the CD horns with another amp (just remember that most of the 600W power rating of the 151’s is driving the 15’s – a max of about 80-100W will be driving the horns.)

That would mean you’re looking for only about 3.5K in amp power (which is just small enough to run from a single 13amp supply)… And you will get more from that than you will from the mis-matched 6K…. Just don’t accidentally send anything but high to the horns, as they fry quite easily….:wink:

I’d try keep the rig fairly simple, using the same kind of speakers. The turbosound speakers will sound decent, theres not much point polluting the sound with the crap behringers and nady speakers.

Personally I’d rather have a smaller rig tht sounds fat thn a powerful rig thts all over the shop, I’ve heard some really shitty rigs tht dont work cos they’re just made from all kinds of random speakers tht have been put together carelessly. I’d stick with just buying the turbosound speakers (they’re considerably louder than the others you’ve specced anyway) and use the money u save to buy some more powerful amps (preferably not behringer ones).

Its always better to use amps that are more powerful than the speaker ratings, they will control the speakers a lot better and also u won’t be driving them hard and causing loads of distortion tht blows ur speakers (and ur ears too). Just be careful that they don’t get turned up too far or u can kiss ur new speakers goodbye. Ur rig will still be ridiculously loud for a room in your house, and u won’t be losing anything by ditching the behringers and nadys.

I guess you’ll need the crossover as the turbosounds don’t seem to have passives built in (I might be wrong, the descriptions on that site don’t tell u much) – u don’t really want to be feeding the subs with anything other than bass, and u can take the sub-bass out of what you’re feeding the full-range cabs too unless u really feel u need it.

The behringer crossover looks a good buy as it has a limiter built in, which will prevent anything too high level from being sent to the amps (particularly important if ur using amps capable of supplying more power than the speakers can handle). Take time to tune the rig when u set it up, setting the crossovers at the right frequencies and the amps at the right level. U can improve the sound a lot just by taking 10 minutes to listen to it and set everything right. If u want to upgrade at any point, buy more of the same turbosound speakers.
