yo is there bass-driver inside the speakers or is is just the fulltone drive? how much does just the drive costs? i want to build myself monitors too. |
I'll answer this...
No, it's just one full range driver. Rich won't tell anyone what driver it is, but I would consider betting my left testicle that it is a Jordan JX92/JX92S.

Oh, no.
I'm surprised that nobody has corrected this misconception. For the sake of this discussion, the speed of sound is not a function of frequency. (Except in adiabatic situtations, with specific gasses, in specific frequency ranges, don't quote me on this, please)
Here, get a little education on the behavior of sound waves reflecting off of a surface. SCIENCE!!!!!Shift+1 It's a thing I did a while back to take to high schools and do demonstrations. I did Figure 1 in MS Paint!
Also, nicely enough, Ferry Corsten's "Fire" hits some nice resonant frequencies for demos. I should take video of this when I get back up to Seattle. |

| an 80hz sound wave takes about 10 feet to do a full cycle, compression and refraction. so you wont hear it at its loudest unless your 10 feet away.. this is where the misconception comes from. |

what you are confused with is the physical distance it takes for a low frequency wave to develop. this doesn't have a lot to do with standing waves and accoustics really.

Explain or reword before I call BS. What do you mean 'develop'? Are you describing a specific situation? You too mysticalninja.
also, you didn't correct his statement regarding speed of sound as a function of frequency directly. You were setting him on the right course, but I feel that there are just some concepts that any producer needs to understand, including the basic nature of sound waves. |

he said bass is unimportant because the sound is delayed due to the low frequency. i corrected him, saying that timing is irrelevant (obviously because we're talking about reflections etc.).
i assumed he got his argument confused with the fact that a low frequency sound wave takes a longer physical distance to do one full cycle than high frequency waves - not the effect on accoustics.

No worries Palm, we're good now. 
Sorry for being picky with my physics, and I promise to post pictures after I move. Okay? |

sorry mate, this post is an epic failure.
hs80ms are rear ported. this means the bass flies out the back of the cabinet. bass builds up in corners. his speakers are facing back into a corner.
= standing wave mania.
it is a very bad idea to have your speakers going back into a corner because the frequencies accumulate at a very small point. this happens on all monitors, but really badly on rear ported designs. the reason you have speakers firing down the long end of the room is to reduce late reflections. conversely, you should have them firing accross the short length of a narrow room as it stops early reflections.
he is also massively off axis. unless he sits a good 1-2m back from his computer, hes not on axis. the way the speakers are positioned at the moment makes them akin to headphones, except there will be massive comb filtering in the middle. |
Cheers for that mate, I wasn't aware the HS80M's were rear bass-ported.
If so, then all your observations are spot-on :) |

it applies regardless of speaker type ;) |

You think so? Actually, my background is not really studio design and setups but, more towards installation audio / pro sound.
In that regard, I'm not really qualified to answer.
However, in my experience, I've kept sub-bass units in the corners of certain rooms and have achieved excellent bass response down to 30 Hz without any noticeable phase cancellation.
Mind you, none of these units were rear-bass ported.
JBL SRX 728S, if you've head of them.
Of course, those rooms were acoustically treated w/ low RT60 / RT30 and great intelligibility to start with.
Personally, I prefer flown-subs w/ line-arrays for larger installations.
It's pretty hard to beat the vertical pattern control, low drop-over distance and the even SPL distribution :) |

IMHO, stay the hell away from 2.1 systems. You have to be so particular/precise with a separate sub and someone else just walking in to the room can effect the accoustical dynamics.
With mid or near monitoring systems the sound ideally is the direct output from the speakers with the room tailored as best as possible to reduce colouration (or not as sometimes desired for a particular room "feel").
Flown subs and line arrays are only for live sound reinforcement and while they do offer good clarity for music dependent on good hi frequncy respresentation (classical, vocals etc), I'd take a traditional stack set-up any day for popular music (edm, rock, pop).
LA systems are great in hockey rinks and are actually more efficient in terms of the amount of kit needed (as opposed to regular stacks)but nearly every prolive sound engineer I know perefer stacks. |
