Home Theater

Home theater is the one category in hi-fi where the layout matters more than the equipment, and where the manufacturer of the format publishes the layout. Dolby tells you the angles. Most people ignore them and then buy a better receiver.

Spend in this order

1. A complete channel count. A 5.1 system of modest speakers beats a 2.0 of expensive ones for film, and it is not close. The reason is the center channel: in a typical mix, most dialogue lives there. Without one your receiver synthesizes a phantom center from the front pair, which works only if you sit exactly in the middle. On a three-seat sofa, two seats are wrong.

2. A subwoofer, placed by crawl. Where you put it changes the response enormously, and you cannot calculate your way out of it — room modes depend on your exact dimensions. The subwoofer crawl (sub on the seat, crawl the floor, listen for the most even spot) costs nothing and does more than any upgrade at this budget. The method is in the setup guide. Our subwoofer roundup compares six of them — including two whose manufacturers publish no amplifier power rating at all, and the input spec that decides whether one will connect to your amplifier.

3. Room correction, run properly. It is already in the box — Audyssey on the Denons and Marantz, YPAO on the Yamahas, AccuEQ on the Onkyo. It measures your room with a microphone and corrects for it, and it is the single most effective feature on any receiver. More than any power figure.

4. Room treatment. Cheaper than electronics and it fixes problems electronics cannot. Room correction is very good above about 80 Hz and only adequate below it, because down there the problem is physical rather than electrical.

5. Better speakers. Last. Not first.

That order is close to the reverse of how most people spend, which is why most home theaters underperform their price.

The receiver specs that actually matter

Not the wattage. Every figure at this price is rated with two channels driven — Denon publishes 80 W + 80 W for the AVR-X1800H under exactly that condition. A seven-channel action scene drives seven, from one shared power supply. Nobody publishes an all-channels-driven figure here, so the real number is lower and undisclosed. The FTC-rated spread across the whole bracket is 75 W to 100 W — about 1.2 dB, which is nothing next to a 6 dB difference between speakers.

Room correction quality. Audyssey MultEQ XT on the Denon AVR-X1800H is a step above the plain MultEQ elsewhere. This is the real differentiator.

Pre-outs.The spec nobody mentions and the one that ends upgrades. The AVR-X1800H has 2.2 pre-outs — front left/right plus subs. The AVR-S670H and Yamaha RX-V4A have subwoofer outputs only, so there is no path to external amplification at all. If “I will add an amp later” is your plan, that spec is your plan, and it is buried in a manual.

A phono input, if this doubles as your stereo. Four of the five receivers we cover have one — the Denons at 2.5 mV MM, the Yamaha RX-V6A at 3.5 mV, the Onkyo at 3.5 mV. The Yamaha RX-V4A does not.

Our receiver roundup works through all of it — including the 210-watt figure that is not a rating, and a case where Denon’s own sources disagree about whether a receiver decodes Dolby Atmos.

Atmos, honestly

The third number in “5.1.2” is height channels. They need real amplifiers: a 7.2 receiver can do 5.2.2, and a 5.2 receiver cannot do height at all, whatever it decodes. No firmware fixes that.

Height speakers go overhead — in the ceiling, or as up-firing modules bouncing off it. The commonest mistake is mounting them high on the front wall, which produces an elevated front channel rather than a height channel, because it is not above you. The published angles and the up-firing requirements are here.

What we would skip

Buying a receiver on its wattage. Buying 7.1 when 5.1.2 uses the same seven amplifiers better in a small room. And putting acoustic panels on the ceiling if you run up-firing Atmos — you will absorb the exact reflection those speakers depend on, which is two good ideas canceling each other out.

One thing we do not cover: soundbars. Not because they are bad, but because we have not verified a set of them against the criteria we use here, and a soundbar is a different argument — it trades the layout above for not having a layout at all.
