Question about the two new subs just announced. The descriptions say that they will have amps with toroidal power supplies. With the new class D amps coming out and the switch from toroidal to switching power supplies for the XPA G3 line of amps and the accompanying explanations about how effective both of these latter two supplies are compared to toroidal, what is the advantage to having toroidal amps in the new subs? It seems like something that is bulky and heavy for a product that itself is already bulky and heavy.

That would be nice... most of the info is in the wild, so stop teasing us loyal Emotiva fans! lol Dan Laufman popped in the other night and verified a larger speaker in relation to what I just posted above is indeed on it's way. Yes...and here is a picture of it:  |

It seems like something that is bulky and heavy for a product that itself is already bulky and heavy. That caught my eye yesterday as well and left me scratching my head.-- New Emotiva subs that are Class A/B and use a toriodal. The announcement says nothing about the subs featuring a switching power supply. "Airmotiv S10 ($499): A powered subwoofer with a cast frame, 10” long throw woofer, and a 10” passive radiator. The S10 has a 350-watt RMS Class A/B amplifier with balanced and unbalanced inputs, and a toroidal power supply. With onboard controls for gain, crossover frequency, phase, the S10 automatically switches on when signal is detected." "Airmotiv S12 ($699): A 12” powered subwoofer with a cast frame, long throw 12” woofer, and a 12” passive radiator. The S12 has a 500-watt Class A/B amplifier with balanced and unbalanced inputs, toroidal power supply, as well as onboard controls for gain, crossover frequency, phase, and automatic signal detection and switching." My HSU VTF-15 MK2 Subwoofer features a "2000w short-term, 600w continuous amplifier with a class A/B output stage/switching power supply." |

My HSU VTF-15 MK2 Subwoofer features a "2000w short-term, 600w continuous amplifier with a class A/B output stage/switching power supply." When I purchased my HSU VTF-15 MK2 this year, I was well aware that the HSU sub amplifier was Class A/B with a switching power supply. How? I formerly read a Sound & Vision article: "Dr. Poh Hsu, Founder, Hsu Research;" By Brent Butterworth • Posted: Feb 23, 2014 www.soundandvision.com/content/dr-poh-hsu-founder-hsu-research#LMD6yo8DFv2YfhlL.99"Dr. Poh Hsu has a doctorate in civil engineering from MIT, but his passion for audio and experiments in subwoofer design led him to found his own speaker company in 1991. His subs quickly earned a reputation for high output, outstanding sound quality and great value, and he’s still at it today." "S&V: What goals do you set when you tune the digital signal processors on your subwoofers? Do you make the response flat, or do you put in bumps in the response to give the sub a certain sound?" "PH:: I don’t use DSP, I do the tuning in analog circuitry." "S&V: How do you feel about high-efficiency subwoofer amplifier technologies, such as Class D, Class G, and Class H? Do you feel a traditional Class AB amp offers better sound? Or do you feel Class AB is still viable?" "PH: Further down the road there’s the possibility they’ll come up with something I’m happy with. But most of the Class D amps I’ve looked at have a poor damping factor [the ratio of the impedance of the speaker, typically 8 ohms, to the output impedance of the amplifier] because they have a high-frequency choke to keep high frequencies of the switching circuitry from getting out. Especially with subs, I feel the vast majority of damping is coming from the amplifier, so I don’t like using an amp that doesn’t have a good damping factor. It should at least be in the 50 to 100 range. So I feel Class AB still seems to make the most sense. A Class D power supply is fine, though. If I come across a Class D amp with a good damping factor, I’d be happy to try it out. I have no problem at all with G or H, because those are just Class AB with multiple rails. My old cylindrical tube subs had a Class G amp, and we’re using BASH amps now with switching power supplies that track the incoming signal." |

 I think this is exactly what we're looking for... These would look 100 times better if in real wood veneers! These better sound incredible because the WAF is terrible. |

What about high gloss black? Very reflective if your intent is to use them for HT as well. Just an opinion. |

Remember specs don't tell the end all story to sound quality. Emotiva is likely using these class A/B amps for the subs because they sound best. The sub I use (JM Lab Electra SW900) has a class A/B amp which is conservatively rated at 250 watts. I've read somewhere that it actually measures around 400 watts. Whether it's true I don't know? The point being is that it sounds terrific. It is very musical and when it's hammer time with explosions and such it can fill the room with very loud and clean bass.  |

Off topic, but the term "musical" needs to die. There is no such thing as "musical", either the sub works well or it doesn't. A sub that plays back music really well will do the same for home theatre. You're just confusing newbies when you use such a term. |

Instead, stuff like "good pacing" and "organic" should really determine if your sub (or speaker) is musical.  Now seriously, it isn't just a sub, but the speakers, too. Either they work well or they don't. Either they reproduce the source properly or they don't. |

I have always liked the Black Ash look for speakers.  The Black Faux Leather on my Airmotiv 5S monitors is very handsome and I imagine that is what they have wrapped these new Airmotiv speakers with.  |

Why are there two different photos of the T1 loudspeaker? Unless, there's an AT1 coming too?

I think both Emo subs already facing a strong strong strong competition! Without mentioning any manufactures but there are already proven good 12" powerful subs out there with free shipping and 45 day money back for a few hundred less (even cheaper if you get a pair) than the Emo 12" sub. Just saying....

At this point in my life I'm thinking that a pair of these new speakers from Emotiva will probably be my last equipment purchase in this lifetime. I'm very excited. I don't want anything equipment wise, so I decided that I wouldn't buy myself anything for Christmas this year. I haven't even been looking, but I said that if Emotiva came out with some speakers, or something tube I would give them the first chance at my money. I'm looking forward to adding my fourth pair of speakers to the line up.
