What is the nominal impedance of the speaker?

The speaker has an easy-to-drive 6-Ohm nominal impedance.

Is the speaker compatible with all AV receivers?

Yes, it is compatible with nearly all AV receivers and stereo amplifiers.

What are the dimensions of the speaker?

The dimensions of the speaker are not mentioned in the description.

If these are meant to be flush against a wall how do you connect the speaker cables if the connectors are on the back?

The connectors do not come out of the back but are inside. The speakers remain flush on the wall. It is a good design

Two different screws provided. Which are for the provided molly bolts and which are for the speaker?

The one with threads further apart doesn't screw into the bolts, so they go into the speaker. It makes sense because for things like sheetrock or MDF, screws are typically coarse thread.

Can these speakers be mount on a ceiling, as dolby atmos speakers?

They could but you would have to add a stop on one end to keep the speaker from slipping off the bracket due to vibration.

Usage will be 100% stereo music (jazz, classic rock). no thumping bass but i want sound clarity, warmth and bass. will use with subwoofer. thoughts?

Given the brand and its reputation, my guess is that they would be a good speaker for mids and highs. The specs say 70Hz at the low end. To get good output at 100Hz or below, my preference would be to go with a larger diameter woofer.

Purchased two polk audio rti a1 speakers but they stick out way too far. would the elac debut 2.0 ow4.2 work as well if i paired with a subwoofer?

The OW4.2 was designed as a surround speaker. They work well as side and rear surround speakers and I use them with subwoofers because they do not play low enough on their own. I don’t have any experience with the Polk speakers you mentioned but the Elac speakers are very good for my use case and are only a few inches deep.

Which hardware suits for mounting this on ceiling?

A screw although I wouldn’t do that. If mounting to a ceiling, not recommended by Elac, I would figure out a much more secure way to do it. Personally I’d go with a different speaker. Elac has in-walls you can mount in a ceiling for instance.

Do these speakers connect to my teac need. 3.5mm

No, these are passive speakers.

Finally, a no-compromise solution for a total surround-sound system when space is at a premium and performance is top of mind.

Product Details

ON-WALL SPEAKERS - A solution for a total surround-sound system when space is limited and performance is key. The compact proportions make installation a breeze to bring huge dimensionality with a speaker that makes itself heard but barely seen.
CLOTH DOME TWEETER - The soft-dome tweeter features wide-roll surround & takes response up to 35,000 Hz for life-like high frequencies. The waveguide improves directivity control & eliminates diffraction modes inherent in traditional box enclosures.
WOVEN ARAMID-FIBER WOOFER - The aramid cone shape offers even greater stiffness and damping, far superior to polypropylene or paper. The added strength allows more flexibility in design to achieve a smoother, extended low-frequency response.
THICK MDF CABINETS - The compact proportions of the Debut OW4.2 make installation on side or rear walls a breeze. The MDF cabinets are larger and internally braced for greater stiffness & strength, reducing cabinet vibrations.
REDESIGNED FROM THE GROUND UP - The original Debut Series changed the game & now it’s changed again with the Debut 2.0 Series. Redesigned from the ground up, they sound more remarkable than the speakers that sparked a revolution in high-end sound.

ELAC Ceiling & In-Wall Speakers Editorial Review

The Elac Debut 2.0 OW4.2 speakers have received positive reviews from customers. They are particularly recommended for use as surround speakers and are easy to install on the wall with the supplied brackets. They have a solid build, sleek design, and good sound quality with clear mid and high range output. However, they are criticised for not having good bass response and poor low-end response, which is where the on-wall form-factor is shown to disadvantage. The binding posts are not ideally located and may cause the speaker cables to protrude from the wall. Though these speakers cannot be connected using a 3.5mm jack and are passive, they can be used with a subwoofer.

Pros

Good quality sound for mid and high range output
Easy install with supplied brackets
Sleek design with solid build

Cons

Limited bass response and poor low-end response which is a disadvantage
Binding posts are not ideal
Not recessed for speaker connections
