Start with the symptom, not the product category
A beginner theater commonly combines an AV receiver (AVR), front left and right speakers, a center speaker, surround speakers and a powered subwoofer. In Klipsch’s beginner overview, the center channel carries most dialogue, while the subwoofer handles low frequencies. Those roles make it possible to map a complaint to a likely cause, but they do not prove that new hardware is needed.
Before spending money, describe the problem in one sentence. “Voices are muffled,” “bass is too light,” and “I cannot connect the source I want” point to different investigations. “It does not sound cinematic” is too broad; play a familiar scene and identify whether the weakness is clarity, impact, coverage or a missing function.
#1 Best Overall
- 10" front-firing spun-copper IMG woofer
- All-digital amplifier with 300 watts peak power
- Volume low pass crossover and phase control
- Line level LFE RCA inputs for maximum receiver compatibility
- Dimensions 14 5" x 12 5" x 16 4"
- Dialogue or channel clarity: inspect the center speaker, its placement and the receiver’s configuration before replacing speakers.
- Insufficient bass: inspect the subwoofer level, crossover, phase and location; a new subwoofer is relevant only after those checks.
- Missing layout or connection capability: assess the AVR against the system you actually plan to build.
- No clear complaint: postpone the purchase and complete a setup check. There is no evidence that one category always produces the largest improvement.
The manufacturer guidance available for this comparison explains component roles and room setup; it does not provide controlled tests that measure upgrade returns. Treat broad claims such as “always buy speakers first” as assumptions, not established results.
Check setup before replacing hardware
A misconfigured system can imitate a hardware fault. Denon’s AVR-S670H manual guidance says to determine the speaker system from the number of speakers, then install the speakers and subwoofer according to room guidance. Apply that principle to any AVR, even if your model is different.
- Count the speakers you actually use. Confirm that the receiver’s speaker pattern matches the physical layout. A receiver configured for a center or surround channel that is not present can produce confusing results.
- Confirm channel assignments. Make sure the center speaker is connected to the center output, left and right speakers are not reversed, and surround outputs feed the intended positions.
- Check listening mode and levels. A direct, stereo or all-channel mode can route dialogue and effects differently. Use the receiver’s test tones or calibration routine, if available, and verify that every speaker is audible from the main seat.
- Inspect placement. Keep the center aimed toward ear height and avoid blocking it inside a cabinet. Give surrounds and front speakers clear paths to the seating area.
- Check the subwoofer settings. Verify that it is powered on, connected to the subwoofer/LFE output, and not muted or set to an extremely low level.
- Listen again with a familiar scene. Change one setting at a time so you know which adjustment solved the problem.
Klipsch specifically encourages experimenting with subwoofer location because small movements can create large differences in bass reproduction. A placement change costs nothing and can outperform an indiscriminate replacement.
When speakers should be your first upgrade
Dialogue is unclear
In a conventional 5.1 layout, the center channel is primarily responsible for dialogue. If voices remain recessed while effects are loud, the center speaker and its integration deserve attention before you replace every speaker. First verify placement, level and the receiver’s dialogue or dynamic-range settings. If the center is an obvious quality mismatch, damaged, undersized for the room or simply the weakest component, a better-matched center speaker is the targeted upgrade.

One channel is limiting the system
Listen to a scene with a steady sound moving across the front. A tonal jump, distortion or drop in level when sound reaches one speaker indicates a channel problem. Replace the faulty or mismatched unit rather than buying a new AVR that leaves the same speaker limitation in place.
You are moving from an all-in-one package
Separate speakers can offer a more flexible path than compact bundled speakers, but compatibility matters. Keep the front three speakers from the same family when possible so voices and effects retain a consistent tonal character. The available guidance does not establish a particular brand, model or measured performance advantage, so choose by fit, placement and compatibility rather than a universal ranking.
What to verify before buying speakers
- The number of channels your AVR can drive and the channels you intend to add.
- Available space, stand or wall-mount requirements and a clear path to the listening position.
- Whether the center speaker fits beneath or above the display without being aimed at the floor or ceiling.
- Whether the new speaker is intended to blend with your existing left, right and surround speakers.
- That the complaint persists after level, wiring and placement checks.
When a subwoofer should come first
Identify a genuine low-frequency limitation
A subwoofer is the focused choice when your system lacks weight and extension in bass-heavy music, explosions or atmospheric effects, while voices and midrange sound balanced. It is not a cure for muffled dialogue or a missing surround channel. If your current subwoofer reaches the required level cleanly, changing speakers may address the real weakness instead.
Placement is part of the upgrade
Low frequencies interact strongly with the room. Klipsch’s beginner guide states: “Experimentation with subwoofer placement is highly encouraged; slight adjustments can create big differences in bass reproduction.” Try several locations and listen from the main seat. A position that sounds powerful beside the sofa may create a null at the listening seat, while a modest move can smooth the response. Leave room for ventilation and a safe cable route.

Subwoofer checks before purchase
- Play a bass sweep or familiar soundtrack passage at a moderate level.
- Move the subwoofer to a few practical positions, keeping the same receiver settings.
- Confirm the receiver recognizes the subwoofer and that the speakers are set appropriately for bass management.
- Adjust level and phase gradually; return to the previous setting if the sound becomes boomy or hollow.
- Only then decide whether the existing unit lacks output, extension or reliability.
Room size, seating location and placement options are therefore purchase constraints, not afterthoughts. A larger subwoofer in a poor location can be less satisfying than a smaller unit placed well.
When the AV receiver should come first
A capability is missing
An AVR is the right first upgrade when it cannot support the system you intend to build or the sources you need to connect. Examples include moving from stereo to a multichannel layout, lacking enough powered channels for the planned speakers, or lacking a required input or control feature. Match the receiver to a defined requirement; do not pay for channel capacity you will not use.
You are choosing between stereo and surround
Denon’s beginner guidance describes a stereo speaker setup with an AVR as suitable for people who do not yet want surround sound or do not have room for it. That means an AVR does not automatically belong after a speaker purchase, nor does a two-channel system need to be expanded simply because a receiver supports more channels. Decide whether your room and listening habits justify multiple speakers.

Plan the layout before selecting the model
Dolby’s Home Theater Setup Guide says: “If you’re building a dedicated home theater and have space to include multiple speakers, an AV receiver with individual speakers for each channel lets you precisely tailor the sound to your room.” Use that as a planning principle. Count the channels, identify source devices, measure the room and decide where speakers can go. Then compare current receiver specifications on the manufacturer’s product page; exact model capabilities change and are not established by the general guidance used here.

Stereo system with no subwoofer
First decide whether the complaint is speaker clarity or missing bass. If voices and instruments are clear but music lacks low-end weight, investigate a subwoofer and placement. If the speakers sound strained or indistinct across the range, address them first. An AVR upgrade is justified only by a planned move to surround or a concrete connection need.
Basic 5.1 package with weak dialogue
Run the setup checks, then focus on the center channel. Correct its placement and level before replacing it. If it remains the clear weak link, upgrade the center with a model that blends with the front speakers. A subwoofer will not solve a center-channel clarity problem.

Good speakers but no surround capability
If your speakers are satisfactory and the desired change is adding surround channels or connecting a source the current receiver cannot handle, the AVR becomes the enabling purchase. Confirm that the planned receiver powers and processes the complete layout.

Note: For ②, main speaker requires LINE IN (Bluetooth/USB/optical/non-wired not supported).
Bass varies dramatically by seat
Treat this as a room-and-placement problem first. Move the subwoofer and repeat the test from the main listening position. Purchase a different subwoofer only if the existing one still cannot meet your output or extension needs after practical placement is exhausted.
Common mistakes that waste an upgrade budget
- Buying by channel count alone: unused channels do not improve a two-channel room by themselves.
- Replacing the AVR for a speaker problem: a new receiver cannot repair a badly placed or mismatched center speaker.
- Adding a subwoofer without testing locations: room nulls and peaks can hide the benefit.
- Ignoring the center channel: in a 5.1 system, it carries the dialogue role, so front-left and right upgrades may leave the main complaint unchanged.
- Changing several components at once: you lose the ability to identify which purchase helped.
- Assuming a guide’s example is a specification: general setup advice does not replace checking the current model’s manual and product page.
How to make the decision with a fixed budget
- Reserve a small amount, if needed, for stands, cables or placement changes that make existing equipment work correctly.
- Choose one measurable goal: clearer dialogue, stronger bass at the main seat or a required receiver capability.
- Spend on the component directly tied to that goal, not on a broader system rebuild.
- Install and calibrate it before evaluating another category.
- Keep notes on the original settings and listening position so you can reverse a change that makes the system worse.
This staged approach also protects compatibility. A receiver selected for a future layout may be sensible, but only when that layout is defined; otherwise the money may be better directed to the speaker or subwoofer that limits today’s listening.
What the available guidance can—and cannot—tell you
Klipsch’s “Buying and Setting Up Your First Home Theater System” explains a typical 5.1 component arrangement and the effect of subwoofer placement. Dolby’s “Home Theater Setup Guide” distinguishes an AVR with individual speakers for a room that can accommodate a dedicated multichannel setup. Denon’s “What You Need to Start Your First Home Theater System” discusses stereo versus surround and selecting a receiver for the planned system, while the Denon AVR-S670H manual page emphasizes matching configuration to speaker count and room guidance.
