I've never heard a set of headphones that I get enough bass definition from. I know it's there, but I often find it hard to discern what the bass player is doing.

IMHO, Bass needs room to develop.

A lot of the time this is down to lovely mixing where the drummer and bass player are playing in a similar frequency range. Even the relatively crappy Sennheiser CX300 in ears I use can manage when the actual track itself is good enough.

For example, the last reference track I used was Under the Influence (Chemical Brothers) which has enormous bass.

I love that track, the initial frequency sweep as it starts is AMAZE and then the bassline just throbs wonderfully. One of the best they've ever done IMO.

This conversation about self-production specifically reminds me of what my brother Porter says about this stuff. He's a pretty huge EDM musician who's constantly encountering stuff like this, and he's coined the term "lofty audio myths" to describe it.

Basically: as hard as people look, it's really, really difficult to find excuses for why your music sounds bad other than that your music sounds bad. Audiophiles are the worst!

I'm building a long style Table Tuba first as I mentioned, purely because I want to see what a £40 8" car audio driver can do in a proper enclosure. I have the wood and driver, just need some spare time to get it started (hopefully at the weekend).

I've already got a pair of T39 PA subs and Omni12 tops from Bill's site and I've got driver for a pair of T60s now too.

The T39s and Omnis are really impressive, I ran them outdoors a few weeks back in a nice big open space and it's just like listening to a very nice quality stereo setup, just a whole load louder... Very very impressive considering the cost to build them.

Have heard almost the full gamut of Bill's designs, and whilst they serve a purpose, there are far, far better box designs for free. The components however, usually cost more. One thing that really irks me about BFM stuff is the almost audiophile way he describes and 'tests' his kit. None of the comparisons to commercial or other subs are done fairly, or in a standard manner compared to other professional stuff - that extends to Tom Danley's newer bits too, awesome sounding boxes but the measurements have to be calculated backwards to be directly compared to their competitors.

Seeing as this whole thing started off on pretty much a whim I've been more than happy with the results so far. I just like how everything is all ridiculously simple to throw together. If there's better I'll have a dig, I'd quite like to manufacture a whole stack of different designs; Big E Loudspeakers seem pretty impressive and are a new company with a slightly different design ethos.

Basically this is a hobby that came about from being loving tired of hearing lovely club sound systems so I wanted to see if it was possible to make better myself. It's actually easier than I thought it'd be though that said it's not like venues round here are actually thinking about the stuff they put in, are getting sold the wrong kit by companies and aren't exactly treating any of the rooms.

One room has loving line array speakers 4 aside and the ceiling is barely 8ft...

I'll certainly have a lookie at those designs, they're definitely interesting but I just like the ease of using a few boxes to cover the entire range rather than using a shotgun approach and having a million different designs sat about the place all doing a smaller section of the frequency range.

Guess that makes me an un-audiophile?

But seriously thanks, I enjoy hacking up wood and pissing about with drivers so I'll add them to the (slowly growing) list.

The easiest way to think about sub placement is when you stand in front of a completely still pond and chuck a stone in. The ripples produced all come from the same spot and are nice and smooth.

Wait for the pond to become still again and chuck in two stones this time, you'll notice that unless you're unbelievably lucky the ripples will gently caress with each other in a destructive manner.

This is the simplest way to explain what happens with more than one sub source, obviously rooms factor into this but y'know...

Olympic Mathlete
Feb 25, 2011





Nah you need the pond. It must be filtered using our new proprietary carbon nanotube filtration system to ensure the surface is completely oxygen free. The filtration system is to be run off our state of the art custom power system which removes any and all noise from the mains cables using anti-matter and so on and so forth... Basically buddy it's $200k to you. Bargain.

Yeah for a lot of things it's cheaper to buy a cable but a few of these runs are fairly long and to get something with Neutriks on was about the same price as just doing it myself and since I had the equipment it was a no brainer to ensure the quality was decent. I'd like to think I was at least competent with a soldering iron considering I put together the passive crossovers for the tops in my setup. I need to get pictures of those, they're pretty nicely done.

http://www.thevinylfactory.com/vinyl-factory-releases/dfa-and-despacio-engineer-john-klett-despacio-vinyl-only-soundsystem/

quote:

Each system is 5-way and it’s kinda obvious what it is: There are two 15s and it’s about 9 and a half cubic feet and the vents are huge but they’re not deep. Early bass reflex cabinets didn’t have the big shelf going back or pipes or any of that stuff, so those are tuned ducts; it’s also a reflex, they call them reflex cabinets, but this is where the vent is the thickness of the baffle.

These are really efficient speakers. For most of the night last night we were averaging about 80 watts, out of each of these mono-blocks, but we were getting very high levels in the middle of the floor because these put out almost 100db per watt.

So, same deal with the mids. It’s one mono-block per box. The stereo amplifier, because horns are much more efficient, we only have 450 watts for the horn and for the bullets and we cross these differently – I’m trying to not get too dweeby – but we’re crossing the horn about 2 octaves above what we could cross it at. I don’t like crossing horns near where they cut off. And the bullets are cut off way above where they normally cut off. You’re not stressing them that way, you can actually put a lot more power into them because you’re moving them less.

This thing on the top is called the birdhouse, because that’s where the tweeters live. And the horn thing is actually a drawer that pulls out and tilts down and it’s pulled out to time-align. All this is physically time-aligned, so there’s no timing other than just physical placement. And then the subs were bought in and they’re 21inch subs – pretty loud – and we’re actively crossing them over rather than using the crossovers in the subs.

So these are 1200 watts each, that’s what they’re rated for, they’ll put out a lot more than that. Last night at one point we were running the stack at about 2000-3000 watts, but we had like 10dbs of float on top of that. These things will actually give you a peak output that’s pretty close to 4000 watts peak.

The crest factor, because we’re using vinyl, there’s absolutely no dynamics, there’s no throttle, this is basically ungoverened. They [James & 2ManyDJs] have to control it back there. I have done the gain structure so it would be hard for them, but they could push this thing over the edge I guess, it wouldn’t be pleasant.

Has something been lost in translation on that last bit y'think? 'cos in the next paragraph he states there's loads of dynamics... :?

Oh and there were 7 stacks there, at a total cost of £1.2mil. So of course, there's another 25 stacks on order…

Talking about watts and dB like they're totally interchangeable is just hilarious. In no way was that system anywhere near close to 4000 bloody acoustic watts of output.

I've never known a band be able to EQ themselves properly. "I'm lead guitar, I should be louder than everyone else by a large margin!" It's usually the bass player that gets a raw deal and he usually doesn't know how to set his tone properly anyway... "I play bass so the bass knob on my amp is turned way up because bass, right?!" and the end result is the guitarist being loud as gently caress, the drummer trying to go louder and the bass player just kicking out a fuckton of midrange and the entire thing sounds poo poo.

One place I'm more than willing to spend a few extra bucks on cables is Neutrik connectors for cables that see frequent use. The strain reliefs they use beat any other I've seen hands down, and they're typically rated for twice as many insertion/removal cycles as the cheap ones. Part of my job is designing and building high-tech classroom consoles where the cables will typically be plugged in and unplugged several times a day in addition to taking a lot of abuse from being moved around, tripped over, etc. Neutrik rebrands their connectors as Rean and sells them for half the price with nickel plating instead of gold and powder coat, so it's not even that much more.

I love Neutrik stuff, their entire line is great, I never knew Rean were a rebrand of theirs. I'm also a fan of Amphenol kit, particularly for stuff like instrument cable plugs as they're just a joy to solder.

We all hold a certain vibrational frequency, not to mention our bodies are estimated to be about 70% water… so we can probably expect that musical frequencies can alter our own vibrational state.

Every expression through sound, emotion or thought holds a specific frequency which influences everything around it—much like a single drop of water can create a larger ripple effect in a puddle.

432 Hz is said to be mathematically consistent with the patterns of the universe. Studies reveal that 432hz tuning vibrates with the universe’s golden mean PHI and unifies the properties of light, time, space, matter, gravity and magnetism with biology, the DNA code and consciousness. When our atoms and DNA start to resonate in harmony with the spiraling pattern of nature, our sense of connection to nature is magnified.

...and then never does anything about it. It's pretty annoying. The most hilarious part of it all being he made some speakers and they sound so loving weak it's unreal. Like you could buy a pair of $50 garage sale speakers and they'd sound better than these things he spent weeks and hundreds putting together.

Is that thread representitive of normal audiophile behaviour or is it an edge case?

Wrapping your mains cables in foil is just pointless and stupid. In fact virtually everything audiophiles is pointless and stupid (and also massively expensive).

Anyone else care to chime in here on the factors that would make the most difference to a sound setup? Environment and the actual speakers would make the most noticeable difference, cabling would be way down the list under the format you're firing through the speakers...
