Stupid question but why all these powered speakers from Emotiva? If we already have huge, powerful, quality amps from them why would we not want passive speakers? I am just thinking from a HT set-up point of view, already have an XPA-5... The Airmotiv and Stealth line of self-powered speakers were developed for "professional" studio work. They weren't initially targeted for home use, but some of us do use them that way and they work quite nicely in the right applications. See here for more detail..... Emotiva ProEmotiva is currently developing a new line of passive speakers (based around the AMT tweeters found in both the Airmotiv and Stealth products)and will be bringing those to market soon. Hope this helps...  |

Hope this helps... That's what I assumed since they were called "studio monitors", just saw so many people use them in HT. I also saw so much hype about this 88 which again is powered. Glad to hear they are making some passives so we can keep our awesome XPA/XPR amps, looking forward to it. |

I am just thinking from a HT set-up point of view, already have an XPA-5... From an HT/living room point of view. To be perfectly honest I find the powered speaker approach to be rather cumbersome for a person not used to them. Long XLR cables, power cables going to different outlets. My only real problem with them. They were designed for pro use like the previous poster said. But I honestly don't think they are suited for that purpose. The airmotivs and the DC-1 DAC really shines best for enjoyment in a musical sense - not pro use. |

It is thought that one gets better quality when each driver has it's own matched amplifier. Were you do do this yourself you'd need 4 mono block amplifiers in the case of Stealth 6s or Stealth 8s. That's per pair. That's a lot more expensive and it's also more wiring.

I don't mind the cable spaghetti; it cancels out the noise!  |

The biggest reason for using a powered monitor - no passive xover to try and fight current through. Most passives are extremely inefficient, and choke out a lot of the amp's power before it actually makes it to the driver, wasting it as heat within the speaker cabinet.

DJ After trying a pair of Stealth 6, my first active monitor purchase (I have owned powered speakers in the past), I know going forward that I'll never return to passive loudspeakers again.  |

When I ordered my Stealth 8's about a month ago, I had been trying to hold out for the 88's so I "prodded" the sales rep on the phone trying to get some info...he just laughed and said they've been put on hold... I hope it's not on hold too long! I'm gonna have a place for a pair of these soon! |

On the bright sight, those Stealth 88s going on hold may have saved me some money.

DJ Do these speakers have active xovers? Stealth 88? Not out yet, but I'll go out on a short limb and say "yes." Similar to the Airmotivs and Stealths that came before them, they'll have active crossovers that happen prior to amplification, as well as on-board discrete amplification for each frequency range. I don't know whether each of the two midrange/woofers will have separate amps though. |

DJ This is just silliness talking and it is not how passive crossovers work. Indeed a high order passive network will increase the efficiency of a system. Crossovers do not waste incoming power as heat (well, the resistive component does, but that is true of all resistive components of all electrical systems, the biggest "culprit" being the voice coil of the driver. Voice coils, especially in woofers, "waste" most of the power being input, on the order of 99% in many cases. Look up "eta naught.") |

woooo, they are ugly as heck! Curious to see what they are priced like. The active vs passive xover debate always makes me smile.

The active vs passive xover debate always makes me smile. +1 ; It would be nice if they considered a speaker grill as many active designs find their way into homes Otherwise the baffle is good as its obviously designed for low diffraction to help the drivers . Could be worse with a stepped design to help with a phased array like an old duntech etc  encrypted-tbn0.gstatic.com/images?q=tbn:ANd9GcSKytFRxB3QYutpSg9XlCrIdCqzxB4E0M-ML1Cd0oDv9I_FoOWqug |

Voice coils, especially in woofers, "waste" most of the power being input, on the order of 99% in many cases. Look up "eta naught.") "There is information presented here that I have not seen in any other material on the subject of crossovers, with the exception of my article, "Biamping - Not Quite Magic, but Close". Specifically, this is to do with the shift of filter frequency and alignment that occurs when a voice coil is hot. Since a stable operating temperature will never be achieved with music signals, there will be a constantly shifting crossover frequency, and a peak in the frequency response where the amplitude is dependent on the power at any instant in time. This cannot be considered a satisfactory situation, and is quite possibly one of the most compelling reasons to use active crossovers whenever possible. There will always be power losses in a passive system - this is generally referred to as 'insertion loss', and all resistors and inductors will create power loss and thus, heat. Capacitors will generally contribute very little loss, and will not get hot - a potentially notable exception being old, dried out bipolar electrolytics. This is another very good reason not to use them, but the main reason is that their value will change over time, and will upset the crossover frequency." |

Typically, the drivers in a speaker have different sensitivities. Therefore the driver or drivers with higher sensitivity have to be "padded down" to equalize the speaker response. That's were a good bit of power may be wasted. Padding down a driver by 3dB (not unusual) throws away half the power of the amp driving it.  Russ |

Russ Which is why speaker matching by component amplifier is so critical - something I'm certain Emotiva has done for their active monitors - to minimize the need for this as much as possible. The ability to match driver impedance to amp creates a greater flexibility to eliminate the need to dampen the driver. |

I truly look forward to this speaker after living with the stealth 6 for a bit. I think that for a 2 channel large room setup these speakers will be incredible full range. My fiancé likes the stealth 6 a lot. She said the other day. "Do you think they will make a really big version of these so we can have them in the living room without a sub?" I love how she is involved and plays to my hobbies. It has been mentioned, but I would be a bit more interested in a Stealth66. Hopefully this is in the works for the future. |

What she didn't realize is that all you heard out of that was "do you think they will make a really big version so we can have them in the living room?" Because....they aren't competing with dual PSA's  |
