Bronze Member Username: OlogyaudioColumbus, Oh USA Post Number: 30 Registered: Oct-05 | Looking for the right person to send the 6.5" prototype to when it comes in ;) Granted it will go through a lot of people first... but may as well show it off here too if it is wanted ;) |

Silver Member Username: MixneffectOrangevale, Ca. USA Post Number: 509 Registered: Apr-05 | "94 dB 6.5" midrange driver" OUCH !!! What tweeter will compliment this beast? Hopefully not a horn loaded transducer. The tweeters mentioned (JL XR tweeters/LPG silk domes) would not match up at all. I am in favor of paper verses alum/mag/polly/kevlar/mineral comp.......etc, but high SPL paper drivers tend to have crappy/choppy FR. Seriously, how exactly is a 6.5" diaphragm going to reproduce flat response up to 10khz? Most 1" tweeters have a hard time accomplishing such a task. I was just wondering what are the thiels on it? Qes= Qms= Qts= Bl= Cms= Mms= Rms= Vas= Fs= Xmech= Le= Re= IMHO DVC spells trouble for anything other than subs. The Qms should explain alot. |

Bronze Member Username: OlogyaudioColumbus, Oh USA Post Number: 33 Registered: Oct-05 | I'll let ya know the t/s when the driver comes in and we get some tests run on it. Yea we dropped the XR tweeters after I convinced my partner it was a bad idea... Prolly going with dayton neo tweets for the low end. Being off by a dB or 2 in sensitivity isnt a huge deal, especially if you consider that many people have their tweeters a great deal closer to their heads than the midwoofers. Only educated guess as to what the top end looks like... again we will know for sure when we get measurements -- I'm sure he didn't mean perfectly flat... more like... extension... if we see perfectly flat I'll be elated The phase plug should help but... The highest these midwoofers will be lowpassed is 3.5khz 2nd order so we don't want crazy things going on just above the xover point... These mids rly should be some PHL type midranges... just sporting 13mm of xmax Whats wrong with DVC on a mid? Just an extra set of leads ;) |

Silver Member Username: MixneffectOrangevale, Ca. USA Post Number: 511 Registered: Apr-05 | DVC = two voice coils on the same former, not just two leads DVC spels extra weight = less controll. Human ear is most sensitive to mids than any other F. We are many times more likely to identify a bad sound in the midrange than bass or highs. So if a midrange driver has a choppy FR then it will be noticable right away. "Being off by a dB or 2 in sensitivity isnt a huge deal, especially if you consider that many people have their tweeters a great deal closer to their heads than the midwoofers." A deviation of dB is definately noticable on a FR, especially in car applications where the listener is confined to a compact space. IMHO the tweeter has to be in perfect alignment with the midrange. When people put the eyeball tweeters up by the visor and the mid in a kickpod or door, that spells crap imaging. I wouldnt rely on moving the tweeter closer to the listener to make up for efficiency imballance. Just my .02 |

DVC doesn't necessarily mean extra weight. You can have the same amount of copper in the gap through the use of two coils that are 1/2 the size. Well the mid-low end sets using 92-93dB/w efficient tweeters... honestly ends up being far more ideal that any other sets I can think of at about that price... Alpine type X for example the tweeter is 4dB less sensitive than the midrange. I don't think there's much of an issue here if the critical midrange is better than +-1dB and the FR is +-2 or so dB full range... especially since after it is installed diffraction problems will make a mess of the FR regardless. I agree that the tweeter should be within say 3 wavelengths (at the xover point) in terms of spacing in the Z axis for proper imaging. Phasing of the tweeter is useful ;) The higher end set I will optimize the hell out of... Leaning for a lower xover point (higher order) allowing for a less sensitive install, a more robust tweeter is nice... More even power response |

New member Username: FeandilPost Number: 1 Registered: Nov-05 | About this ridiculous comment about DVC = less control... you DO know that a DVC coil weighs the EXACT same as the coil if it was SVC??? the EXACT same... it is literally simply SEPERATING the longer coil into two coils those speakers adire makes is a joke in comparison 85db/w vs. 93db/w no faradays... no top end... less excursion... less power handling you're looking at easily 112db of max SPL with 125w RMS with these from 90hz-10khz this driver is flat as a board till 10khz... 4 layer aluminum voice coil, and dual faradays with the top and bottom plate shorted it's the exact driver Adire would make if they made a more efficent extremis... I designed it and the prototype will be here in around a week or less... as far as good tweeters to mate with it... it's realitively simple to find something... however this speaker was specifically made to do something nothing in 6.5" could do till now and that's mate in a 2-way situation with a horn or ribbon tweeter however there a few domes that will mate quite well |

New member Username: FeandilPost Number: 2 Registered: Nov-05 | Qms is 3.4 Xmech is 17mm or so 1 way Mms: 8.9 grams BL: 8.6 N/A Le: 0.09 mH XBL2 DVC spells nothing for nobody... it's the same as a SVC 8ohm but with wiring options... absolutely not a single specification changed going to DVC from SVC |

Gold Member Username: Mikechec9Http://www.cardomain.c... Post Number: 1442 Registered: May-05 | as admirable as your theoretical prototypes seem to be, there seems to be a real lapse in PR. try some smileys with pig tails or somethin ()and positive comments. not certain if you meant to sound as negative as you do, but forum news spreads faster than your supposed shipment. just food for thought |

New member Username: FeandilPost Number: 3 Registered: Nov-05 | I'm not sure what to say to that other than you obviously took what I said as something completely different I was pointing out the errors in your posts... I'm sry if this offended you Cheers |

New member Username: FeandilPost Number: 4 Registered: Nov-05 | oh and Dan wiggins and David hyre designed and built the speaker... I assure you it's clean till 5-6khz and good till 10khz and just so you know the PHL 1120 is an example of a speaker already capable of doing this it's not really all that hard |

Gold Member Username: Mikechec9Http://www.cardomain.c... Post Number: 1448 Registered: May-05 | "oh and Dan wiggins and David hyre designed and built the speaker..." well then, why didn't you just say so in the first place. cheers! steve "kep" built my brahma hybrids. is this the same driver that is supposed to take the place of the extremis, (between the 6.5 koda and extremis) or is it completely separate as well? |

Silver Member Username: MixneffectOrangevale, Ca. USA Post Number: 512 Registered: Apr-05 | Qms is 3.4 Xmech is 17mm or so 1 way Mms: 8.9 grams BL: 8.6 N/A Le: 0.09 mH XBL2 Qms is really low for a driver with DVC. I ll explain later. Mms is really low. Bl is 8.9, NO WAY, not with a Mms of 8.9 you wont. By the way what is the Qes? |

Silver Member Username: MixneffectOrangevale, Ca. USA Post Number: 524 Registered: Apr-05 | Dylan, Any word on those comps. I am interested to know if they are what they were supposed to be. |

Bronze Member Username: OlogyaudioColumbus, Oh USA Post Number: 35 Registered: Oct-05 | qes should be ~.3 if dan did his job right -- still waiting on proto to test for sure... it can varry a little bit and still be useable... If it isnt this than he simply changed something out for a better option -- but it should give you an idea on how they model -- Pretty much line up down low with the extremis in the same box with 1 watt -- however the higher reference efficency... well you get the picture I'm sure Anywho -- EQ up the bottom end -- or use as a mid -- or use as a small subwoofer... any way you go about it... it goes rather well What were you saying about the qms? |
|
Silver Member Username: MixneffectOrangevale, Ca. USA Post Number: 525 Registered: Apr-05 | High Qms = better controll on rebound between cycles (F). As the woofer pumps in and out, a woofer with higher Qms would have better controll. Kinda like a car engine. Some engines, when you rev it up and then release the gas pedal, some take forever to come back down to idle, while some will reduce much much faster, therefore having tighter response. This would be better. Low Qes = high motor energy. |

Bronze Member Username: OlogyaudioColumbus, Oh USA Post Number: 36 Registered: Oct-05 | $60/ea preorder... whenever that happens... which is when we get the prototype in and make sure it behaves like it should... As for that high QMS = better control on rebound = less linear distortion.... where did you ever see that one? The lower the QMS the higher the rms (driver's mechanical losses) Gotta watch QMS vs impedance curve... a too low QMS will result in a nice big hump at Fs... As for BL with that mms... well the parts have already been designed and made by dan (adire audio)... just things need assembled... which is taking way too long... And I may venture to say that these are defiantly up there with the best drivers on earth (assuming they come out to spec) You will want to EQ up the bottom end though if you run them IB... or just live with a relaxed midbass relative to the high sensitivity of the midrange... Pretty much on par with the extremis in terms of low end sensitivity... just that's much lower thn the sensitivity though the midrange... In a small ported kick you can get flat highly efficient response to 80hz no problem... 50hz if you go a little larger... Or go with a 3 way ;) using 2x of the 6.5s -- one in ~.7cuft tuned to 32hz and a 4th order lowpass at about 70hz... and ditch your subs... Kinda big for kicks though if you ask me... some people could manage though... |

Silver Member Username: MixneffectOrangevale, Ca. USA Post Number: 621 Registered: Apr-05 | I am interested to see the FO graph, impedence curve, and Thiel large parameters. Please post them when you get em in. Thanks |

Bronze Member Username: OlogyaudioColumbus, Oh USA Post Number: 38 Registered: Oct-05 | Indeed -- the first place they are going = npdang and mark k for some independant measurements if they don't meet design goals... back under the knife they go... Unless they are better by some fluke ;) |
