Yamaha AVENTAGE 2021 AV Receivers Bulk Up on Power and 8K Features

[3db]

I do love me some big full-range towers of power with dual 12” or 10” woofers.

Its much harder to place a pair of tower speakers in a room that balances bass (due to room modes based on room dimensioms) with room layout and they rarely ever meet. I can tell you with 100% certainity that no high end mega dollar towers and monoblocks will give good bass in my great room due to room layout. I needed 3 subs to tame the bass and make it useable in this room. I could use a 4th sub but have no place to put it. Please stop feeding the ignorant.

Yes, it is uncommon, but it is also a "gotcha" - as the manufacturers do not (usually) advertise their full frequency impedance curve...

All you can say, is that if running 4 ohm (nominal) speakers... you should be cautious, and typically, 8ohm (nominal) speakers, are pretty safe.

So I do tend to warn people ... the low impedance thing can drive you nuts, as the system doesn't sound right, but there is no obvious reason for it... which can lead to random upgrades, and discussions about how different amps "sound different" (yeah they often misbehave differently under low impedance conditions, and their distortion patterns differ...).

And then you try an amp that is stable into 1ohm loads, and suddenly the midrange clicks into place, imaging stabilises, dialogue is intelligible.

It is a frustrating and pernicious problem... (if you have it) - and typically you can only uncover that root cause by finding a proper lab test of the speaker where the full impedance/frequency is mapped....

(and just to exacerbate the problem, most amp manufacturers don't publish data on their 2ohm or 1ohm capabilities....)

All my PSB speakers are nominally 6 ohm and dip into 4 ohm on every system and I have no issue with imaging or smoothness of frequency response across the spectrum, even when listening to them full range at 95+ db. They ars all driven by top three models in Yamaha's line up. Could a budget Yamaha do that without engaging protection circuit or clipping? No. They werent designed to do that but the top model AVRs easily can. I think most modern speaker impedances (designed in the 2000s and up ) regularily dip into 4 ohms and even budget AVRs can drive them in smaller rooms to lesser volumes. Separates arent required to get great sound unless one's speakers have an uncommonly low impedance.

Hey, the heart wants what the heart wants.

I wasn’t trying to feed anyone. Just innocently stating my own personal preference.

I love big towers, and I ain’t gonna lie.
