It is complete, which five products on this shelf are not

Integrated power amp with 700 watts system power.

The amplifier lives in the subwoofer. Connect a television, a player or a phone and the system works.

Five of the thirteen products here are speakers only, and need an AV receiver you must buy:

Energy 5.1, $275 · Klipsch Theater Pack, $549.99 — “designed to pair with your favorite AV receiver” · Klipsch 5.1.4, $749.99 · Klipsch R-620F pack, $988.89 — “connection to your receiver or amplifier” · Klipsch R-625FA pack, $1,298

And this shelf lets you price the missing piece. Three Klipsch bundles share the reference 1065841: BB at $1,298 (speakers), KA at $1,799.99 (+ Onkyo TX-NR7100), KF at $2,198.99 (+ Onkyo and a second subwoofer). So the Onkyo adds $501.99. And the Energy reference 1008207 goes from $275 to $749 with a Denon AVR-S670H — $474.

So a complete system at a hundred and twenty dollars is a different category of purchase, not a cheaper version of the same one.

The cable lengths are published, and nobody else does that

2 fronts and center satellite speakers have a 15 foot single RCA cable, 2 rear speakers have 25 foot single RCA cables.

That is the figure that decides whether a 5.1 system can actually be installed, and it is unique on this shelf.

Rear surround speakers go behind the sofa, which in most rooms means a run along a baseboard, round a doorway, or under a rug. Twenty-five feet is about 7.6 meters (25 ft) — enough for most living rooms, and not for a large one.

Yamaha comes closest with “Speaker wire perfectly matched for each speaker” on the YHT-5960U and “Speaker wire” in the YHT-4950U box contents, without lengths. The Klipsch packs supply no wire at all.

But the RCA connection locks the system shut

Each satellite is fed by one RCA lead from the powered subwoofer, not by ordinary two-core speaker wire.

Two consequences.

You cannot substitute a better satellite. Any normal passive speaker expects speaker wire into binding posts or spring clips, not an RCA plug.

And you cannot extend the run with a reel of cable from a hardware shop.

Every Klipsch and Yamaha system on this shelf uses standard speaker wire, so individual speakers can be upgraded, replaced or re-cabled.

The input list is genuinely better than systems five times the price

Six independent RCA inputs for true surround — so a player with six analog outputs feeds each channel directly, bypassing any internal decoding. Digital optical, which is how a modern television actually outputs sound. USB and SD card, for files. An FM tuner. Bluetooth. An illuminated display with front panel controls.

The Klipsch Theater Pack at $549.99 has no inputs at all, because it has no amplifier.

Seven hundred watts, read against the shelf

Unqualified — neither RMS nor peak.

And the inversion on this shelf is worth seeing whole: this at $120.88 claims 700 W · Sony at $329 claims 600W · Yamaha YHT-5960U at $749.95 claims 80-Watt · Onkyo TX-NR7100 claims 220W per channel at 6 ohms.

The Yamaha’s eighty watts is the honest figure — a real per-channel rating for an AV receiver. Seven hundred watts from a system with 6.7-inch satellites is a system-total peak number.

Note also “20 Hz – 20 kHz” attributed to the subwoofer: a subwoofer covers roughly 20 to 200 Hz and is crossed over below the midrange precisely so it does not go higher. That figure is the system’s, misattributed — and it has no tolerance either way.

And “magnetically shielded” dates the design

Shielded driver magnets mattered when televisions were cathode-ray tubes: a CRT steers an electron beam with magnets, and a stray speaker field bends it, producing a colored patch on screen.

Flat panels have no electron beam. The claim is not false; it is answering a question nobody asks.
