@viceadmiraal61 You lack basic knowledge of electronics. You only need cable thick enough to carry the current to maintain the damping factor. All the silver in the world will make no difference beyond that. Just put a dual trace 'scope on both ends of the wire and invert channel B while adding them. If the result is a flat line, the cable cannot be improved on. All you audiophools wasting money on fraudulent cables. I'd rather get my wife a nice diamond, than wasted on something of no value.
@viceadmiraal61 Did you ever hear of "The Emperor's New Clothes"? That's what your snake oil audiophool $12,000 solid silver cables, cable lifters and toobs are.
Anyway, your 'intelligence' precedes you. Enjoy wasting your money on overpriced speaker wire. I'll enjoy the music.
@MightySaturn5 To date, the highest power amplifier I'm aware of is the Powersoft K20, at 18,000 watts. It has intelligent dynamic management, so it can delivery bursts of any power up to 18kW, and can be dialed down to reduce power in accordance with voice coil heating. They're made in Italy and may not be user-serviceable the way the QSCs are. I looked briefly at the Crest 10001, but there were some things I didn't like about them and opted to go with QSC.
@basspig Powersoft, Lab Gruppen, Martin and a few others have achieved enormous wattage ratings using h.f. switching power supplies,these companies make excellent products however they and others rarely give a 20-20khz spec at full power @ less then 1% thd whereas the 10001 has such an overbuilt power supply that it can do 5000 watts per ch. into a dead short (1 ohm) at perfect fidelity, of course it draws 72 amps and is impractical to lug around (140 lbs) however its fidelity is unmatched
@MightySaturn5 The switching power design is actually superior, because the power is being supplied 180,000 times/second, instead of 120 times/second. The power factor is closer to 1.0 (is very poor with linear supplies) and because of the HF switch rate, core size for transformers is drastically smaller.
At full load into 2 ohms with max unclipped output, the QSC PL9 willdraw 126 amperes from the ac mains.
@basspig -I understand the design and efficiency ratio of hfps's to traditional 60hz (120 alternations) designs and have even made a few smaller switching power supplies used for simple ac to dc conversion / reduction however in the times we've used the PL9 ( 9 shows presently) we've never seen it draw that type of current when driving two (per channel) of our ground stackable EAW SB1000e's
@MightySaturn5 You won't see that kind of current draw with typical music, due to the crest factor of such program content. Those max current draw specs are continuous sine waves for testing purposes (FTC power rating).
As I recall, the reason we went with the QSCs was power into 8 and 4 ohm loads was higher due to higher swing voltage of the power supplies. In fact, when you bridge these amps mono, NEMA Class 4 wiring to the speakers is required.
bridgeable or monoblock prefered as i run one amp per sub. was lucky enough to be given a JBL 4645c, and might be getting another 2. got a Citronic PPX900 at the moment for the one i have already.
That's a pretty competent sub and it has a maximum peak power handling of 3200W, which, to take advantage of, you'll need amplification that can deliver close to that, at least for short term peaks. While any good consumer audiophile amp will work great, if you want to push to extremes, an industrial amp from QSC or PowerSoft may be preferable. QSC's PL380 would work nice into a pair of these. Remember to use a high pass filter @20Hz!
jesus H christ. that's some serious gear. i'm trying to put together a PA for a band. thinking about a set peavey SP6s for FOH.. but i need advice on subs.. folded horns or regular subs? what are the characteristics of each type? i'd rather sound really good (complex musical detail, punch, whatever) than really loud.
Hey, hey... we just put in a full projection system and 154" AT screen this summer, and some more gear.
If you're not doing urban or hip-hop concerts, then a number of good vented subs exist. BassMaxx Technology just started marketing a vented sub, in addition to their horn-loaded subs. I can't recommend the horn loaded subs because of the craggy response curves. If you stack a cluster of vented subs together, it's almost the same effect, only with flatter response. Keep all subs clustered.
My first woofer systems were horn-loaded. The problem is that to achieve low frequencies, the horn mouth has to be huge. To get down to 16Hz or so, the horn has to be somewhere around 32ft wide at the mouth. Obviously not practical. I had some W horns that were good down to 85Hz or so. They had a mouth of about 4ft. Response was NOT flat in any range. I also had Community SRH60 midrange horns. Again, big peak at 960Hz, nothing much below that.
Thanks. I'm inresting in something compact like bassmaxx x3c trip which is a folded horn sub. 4 of them should go with -3 dB response to 29 Hz in half-space and who knows how low with electrical correction indoors. I like to play deep indoors and loud outdoors, but I always seem to lack depth or volume. I also like straight uncolored responce.
What I'd like to find out is if folded sub horn efficiency is only useful outdoors or if they also perform better than a couple of reflex 18s indoors.
The X3C Trip is a fine system, but it has a specific application and that's to get loud with minimal cabinet volume. Behing a horn, it has a rocky response curve and a sharp cutoff at the low end. But 29Hz is pretty low and I think it could stretch lower if you don't expect full output. But for a hi-fi system, I would go with LLT and double up on the woofers. Such bass has far less coloration and more detail. Bassmaxx is for large venues and minimal truck hauling.
Two words: Bigger monitor. That 47" looks ridiculously small in the middle of all those speakers...
But holy crap, this is more woofage than Steve Meade's truck, and i bet it's got a lot more SQ as well. Freakin awesome man! Also, nice studio you got there.
Music has been a passion of mine for half a century. I used to DIY all my gear, and up until 28 years ago, it was all tube, homebrew amplifiers, as well and homebrew speakers. Then electronics technology got too good for me to keep up with in DIY, so I started buying gear in the late 70s and into the 80s.
HD video seems not to play well on single-core computers. My quad cores play it fine, but not my single core Athlon.
ya im really interested in speakers and the technology behind them. its a shame though i think i a bit tone def. and by homebrew speakers do you mean everything even the drivers?
but for the HD thing i dunno. my cpu is only at 70-80% usage while watching.

yes a do..a have the mony for it....yes you not..that is your driving problem
jealous low budget guys..we audiophile must have same patience with them
sadness can not satisfy them..it became a hallow habit to hallmark
audiophil as overload big spanders........

now a know wy you don,t here div cabels in loudspeakers.......you drown your ears
in bassssssssssssssssssss sound only..and next time use a windcap on
the mic recording the steam loc 75.....blubber low end sound...a thougt you
are a pro in soundrecording...and this video next time recoding the real sound
with mic..not playing a direct cd sound........if you want to be straight..
