Do the Contour 1.1 speakers need a powerful amplifier?

Yes. At 85 dB sensitivity and 4 ohm impedance they draw real current, so a high-current integrated or power amp gets far more from them than a budget receiver.

How much bass do they produce?

The rear-ported cabinet is rated down to 47 Hz. Bass is tight and quick rather than room-shaking, so a subwoofer helps in larger rooms or for home theater.

Can I place them close to a wall?

The port fires from the rear, so leave some space behind them. Owners report better imaging and less boomy bass with breathing room and stands.

The pair of speakers is the core package. Stands, speaker cable and amplification are separate purchases you will need for a working system.

Are they good for home theater?

They work as high-quality front or surround speakers, but their limited low-end reach and amplifier demand suit a system built around a subwoofer and capable electronics.

How do they compare with the Contour 1.3?

The 1.1 is the smaller two-way with less bass extension and output. The 1.3 adds a larger cabinet and driver for more low-end weight, at the cost of size and placement flexibility.
