TV Home Theater: Surround Sound, Projector, DVD Player, or Cable - What Should You Buy?

Upgrading your TV home theater comes down to what you already have. Compare a 200W surround system, a region-free DVD player, a 2500-lumen DLP projector, and a simple RCA cable to find the right fit for your space and spending.

Quick Take

Upgrading your TV home theater isn't about buying everything at once. It's about finding the missing piece. If your TV's speakers sound thin, the Bobtot surround system can replace them with a full multi-channel setup. If you still watch discs, the Geoyeao DVD player handles region-free playback and upscales to 1080p. If you want a giant image for movies, the Casio projector brings DLP projection to your wall. And if you just need to connect older components, the 3-RCA cable does it for a few dollars. The price range on this list is $4.30 to $129.99, so choose based on what your current setup lacks.

How to Choose

  • Bobtot Surround System - Choose if your TV speakers are the weakest link and you have space for multiple speakers. Keep in mind it's the higher-priced option.
  • Geoyeao DVD Player - Choose if you still watch discs and want a player that handles more than a basic DVD player. Keep in mind it costs the same as the surround system.
  • Casio Projector - Choose if you want a large display without buying a new TV. Keep in mind this is a used unit.
  • RCA AV Cable - Choose if you already have the components and just need a physical connection. Keep in mind it's a short cable.

Product Notes

Bobtot 200W Surround Sound Stereo System for TV 5.1/2.1 Ch Home Theater Subwoofer

200W Surround Sound Stereo System for TV 5.1/2.1 Ch Home Theater Subwoofer

This complete surround system brings five speakers and a subwoofer to your TV setup. The package includes a center speaker, two front speakers, two rear speakers, and a main unit with a 4-inch subwoofer and built-in receiver. You can run it as a 5.1 or 2.1 channel setup, depending on how many speakers you want to place. Bluetooth connectivity allows wireless music streaming, and HDMI audio input means you can connect a TV or other source with a single cable. The design is compact enough to fit in small rooms, and a 1-year manufacturer warranty is included. It's one of the higher-priced items on this list, so it's a serious commitment to better audio. The main limitation is the number of components: you'll need room for all speakers and the subwoofer.

Blu Ray DVD Player, 1080P Home Theater Disc System, Play All DVDs and Region

Blu Ray DVD Player, 1080P Home Theater Disc System, Play All DVDs and Region

This disc player is a strong option if you still have a library of DVDs and want them to look better on a modern display. The Geoyeao EVP-102 upscales DVD video to 1080p through its HDMI output, and it's compatible with NTSC and PAL discs from all regions. That makes it useful for imported titles that many fixed-region players won't accept. Beyond HDMI, it has composite video output for older TVs and a front USB port for JPEG, MP3, or WMA files. Dolby and DTS audio output let you route sound to a compatible receiver. It costs the same as the surround system, so you're choosing between audio and playback. The main limitation is that you need to be a disc-heavy viewer to get the most value from it.

Casio 2500 ANSI DLP Projector for Home Theater Movie Lovers Cinema TV Video Full HD 3D

2500 ANSI DLP Projector for Home Theater Movie Lovers Cinema TV Video Full HD 3D

This Casio XJ-M141 DLP projector brings a large picture to your wall without the need for a massive TV. It outputs 2,500 ANSI lumens, so it can handle moderate lighting, and its laser/LED hybrid light source is designed for long service life. The projector can operate 24/7, making it flexible for both residential and presentation use. It has a native resolution of 1024x768 and a 4:3 aspect ratio, with HDMI, VGA, S-Video, composite RCA, network, and RS232 connections. Built-in speakers mean you can get started without an external sound system. The unit is sold as used, so the lower price is a trade-off for that condition. The main limitation is the used status, which means you're buying someone else's projector rather than a fresh unit.

3 RCA to 3 RCA Male to Male Composite AV Cable for TV DVD Home Theater- 1m

3 RCA to 3 RCA Male to Male Composite AV Cable for TV DVD Home Theater- 1m

This is the simplest item on the list, but it can be the one that makes everything else work. The cable has three male RCA connectors on each end, carrying composite video and stereo audio between devices like DVD players, projectors, or older TVs. It's shielded to reduce EMI/RFI interference, and the gold contacts are designed to maintain a clean signal. It's new and comes at the lowest price on this list, making it an easy add-on to any setup. The length is 1 meter, so it's best for connecting components that sit close to each other. If you need a reliable cable for an existing RCA connection, this gets the job done without changing your other gear.
