How much does a complete home theater system cost?

With separate components we recommend, from about $1,100 for a powered-speaker TV upgrade, $2,017 for a starter surround system, $5,633 for a 5.1.2 Dolby Atmos room, and $8,231 for a 5.1.4 dedicated theater with two subwoofers. Speaker wire and mounts add a little more.

Is a home theater in a box worth it?

Rarely. Boxed systems hit a low headline price by pairing a receiver with small speakers, and none of the parts can be upgraded on their own. A receiver and separate speakers cost more at first but sound far better and can grow one piece at a time.

What is the difference between 5.1.2 and 5.1.4?

The last number is the count of height speakers. Two heights give overhead effects a clear front-to-back sense; four add a second pair behind the seats so sounds can move across the ceiling. Four heights need a receiver with at least nine amplified channels, such as the Denon AVR-X3900H in our dedicated theater.

Can I mix speaker brands in one system?

Keep the three front speakers from one family, since sound pans across them constantly and a mismatch is easy to hear. Surrounds and height speakers matter less; our Atmos systems use Polk surrounds and Klipsch in-ceiling heights with a Polk front stage, and room correction evens out the rest.

Can I buy a system a piece at a time?

Yes. Start with the receiver, front speakers and subwoofer, which carry most of a film's sound, then add surrounds and height speakers later. Each system here lists how it can grow.

The Dolby Atmos room 5.1.2$5,633
The dedicated theater 5.1.4$8,231

The TV upgrade

2.1, no receiver

Powered speakers with HDMI eARC plug straight into the TV, so the TV remote controls the volume, and a compact sealed subwoofer fills in the bass a pair of bookshelf speakers cannot. Far better than a soundbar for films and music, with nothing else to buy.

System total	$1,100

Growing it: No surround channels, and powered speakers cannot join a receiver system later. If you want surround sound, start with the next system instead.

The starter surround system

4.1, room to grow

A Denon receiver with a front pair, a surround pair, and a sealed subwoofer. There is no center speaker: the receiver blends dialogue into the front pair, which works well when the seats sit near the middle of the room.

System total	$2,017

Growing it: Add a center speaker later to make it 5.1; the receiver supports it. For Dolby Atmos, the receiver would need replacing, so if height speakers are in your plans, look at the next system.

The Dolby Atmos room

5.1.2

Matched Polk Reserve towers and center for the front stage, Polk Signature Elite bookshelves as surrounds, two Klipsch in-ceiling speakers for the height layer, and the SVS PB-2000 Pro for movie-weight bass, all driven by the Denon AVR-X1800H, our default receiver for a first Atmos room.

Growing it: The AVR-X1800H's seven amplified channels are all in use here. For 5.1.4 or 7.1.4 later, step up to the AVR-X3900H.

The dedicated theater

5.1.4

The Atmos room's Polk front stage and surrounds, four in-ceiling heights for a full overhead layer, and two SVS PB-2000 Pro subwoofers at opposite walls for even bass across every seat. The Denon AVR-X3900H powers all nine speakers and adds Audyssey XT32 room correction, with Dirac Live as an option.

Growing it: The AVR-X3900H amplifies nine channels and processes eleven. For 7.1.2, swap two of the heights for a rear surround pair. For 7.1.4, add the rear pair and a two-channel power amplifier on its pre-outs for the extra two channels.
