I remember some time back about Emotiva making high power double wide blades for the Gen 3 chassis.
I'm thinking about replacing my passive sub amp. The Gen 3 2x will probably be fine, but I may have different subs in the future.
Anybody know anything???

why go so expensive for a sub amp?

Mind you, DSP can be done before the amp in multiple ways |

Could we get back to topic?
This isn't about whether you think it's a good idea, it's about what you know about the double wide blades!

Chuck, The double wide module will give 500 watts into 8 ohms as a bridged balanced mono-block module. You can put up to three in a chassis. Chuck I will look for more info on this. This was all I had in my notes. Great job with that trigger timer. I watched the video of it and thought that could work for many as my Harmony remote continues sending commands before all my gear is fired up to receive them. Cheers ! |

Both the double-wide and standard modules are stable into 2 ohm loads.

I power my DIY sub, a 17" driver, 4 ohms nominal in a 140 litre dual ported enclosure with an XPA-100 which has 400 watts into 4 ohms. It's easily the best sounding power amp I have had power that sub and it has no shortage of grunt to shake the floor, rattle the windows, vibrate the walls and let the neighbours know that mine is better than theirs. I have had plate amps, pro amps, DIY amps, Class D amps up to 1500 watts rating etc etc. Most do OK for LFE but to my ears none are as good as the XPA-100 for music.
Cheers

Cheers Gary I have initially used my new XPA5 Gen2 as a sub-amp while my Anthem MCA-20 was being repaired. The XPA-5 (two channels only) outperforms the Anthem hands down! I can't bare to put it back in action! A good amp is a good amp. It doesn't matter what it's being used for - this extends to a sub amp too! I think that at the first of the month I'm going to order a XPA-2 Gen 3 for the subs and move the XPA-5 to its intended location driving the fronts and surrounds. |

I would suggest an alternative - use the Gen3 for the mains to gain the XPR quality, and then use 2 channels from the Gen2 for the subs like you are now.

Let me ask this, not to hijack, but rather to tag along to the OP as it kind of fits, and I don't really want to create a new thread and open up a big debate.
I realize there is a big difference in putting an amp on the LCR of a system. In general terms, For a 5.1 channel system, how big of an improvement does an amp make on the rears, or is the difference marginal and the power from the HT receiver is sufficient to drive them since they really don't do a lot?

Surrounds can do the same thing the Main left and right does. That same explosions or helicopter sound that is coming out of the Mains can come out the Surrounds. Use full range speakers all around and your in for a treat !  |

Use full range speakers all around and your in for a treat ! The punch line for me is panning, when a sound moves around the room, side to side, front to back etc it has to sound the same. It annoys the hell out of me when a moving sound source changes tone, maybe I'm just more sensitive to it than the average person. But we are talking high quality audio on here and noticeably different sonic signatures from different corners of the room aren't what I'd consider high quality. Cheers Gary |

That was another thing I had wondered about that makes sense. Going from 250 watts in front to 100 in back, I would think, would be noticeable as far as playing at the same loudness and same source input considering I would think with the fronts not being driven by the same amp that the gain of playback would not match the level of the receiver, that it would be either slightly louder or quieter, not even taking into account different sound quality from the massive difference in power between the front and rear channels. Damn. Guess I had better just go 5 channel then and get it over with and stop thinking of just going with 3 channels. |

Fully balanced 500 watt per channel amplification in a couple chassis now. Possible Monster speakers in the works from Emotiva. The best sound quality Pre/Pros on the market and game changing room correction. Add your favorite surround sound audio codec, player and display.

You want to dial in your level matching with a sound meter and ideally the software tools available (Dirac, EmoQ, whatever). It's iterative. You don't want to just assume your levels are matched because all the channels are hooked up to one amp. Room acoustics are the biggest hurdles you have to overcome, not amplifier gain. For level matching; not for timbre matching. |
