Is the Motion 4i worth it at $200?

At $200 at eBay as of November 8, 2026, it is a reasonable buy for a small room or surround duty. The tweeter is the draw; budget for a subwoofer if you want bass.

Do I need a subwoofer with the Motion 4i?

Yes for most music and movies. The speaker reaches only 70 Hz, so a subwoofer fills in the low end.

Can a budget AV receiver drive the Motion 4i?

Check that your receiver is rated for 4-ohm loads. At 90 dB sensitivity it plays loud easily, but the 4-ohm impedance draws more current than 8-ohm speakers.

Can I use it as a surround or Atmos height speaker?

Yes. It is compact, wall-mountable and can be hung upside down, which suits surround and height channels.

How close to the wall can it go?

Leave some space behind it. The port is on the back, and blocking it muddies the bass.

One speaker with its grille and mounting hardware. Speaker wire and a amplifier are not included.

Our take on the MartinLogan Motion 4i Bookshelf Speaker

The MartinLogan Motion 4i is a compact 2-way bookshelf speaker built around MartinLogan's Folded Motion ribbon tweeter, paired with a 4-inch woofer in a rear-ported cabinet. It is rated 4 ohms, 90 dB sensitivity and 70 Hz to 23 kHz, with a 2,900 Hz crossover, and it can be wall-mounted or set upside down for surround duty. The best new price is $200 at eBay as of November 8, 2026, against six stores listing it new. That is near the low end of what this speaker has sold for, so the price is fair rather than exceptional.

Pros

Folded Motion tweeter gives crisp, detailed highs for the money
Compact cabinet fits shelves and wall mounts, and can be hung upside down
90 dB sensitivity means modest amps can drive it
Doubles as a surround or Atmos height speaker
Upgraded binding posts accept bare wire or banana plugs

Cons

4-ohm, 75 W RMS rating asks more of budget receivers
Bass is limited: 70 Hz at the bottom, so a subwoofer is needed for low end
Rear port needs breathing room from the wall
3.4 out of 5 from 91 ratings suggests uneven owner experience
Not weatherproof, so indoor use only
