Q: What’s the best current receiver to use with theses
A: Hello. Thank you for your question and we hope all is well. We don't have any models or brands to recommend as the speakers work with almost everything. It's pretty subjective as it will really be a matter of personal preference, including for our staff. However, something that might be helpful is we do recommend an amplifier power of 20-140 watts per channel. If you are providing around 100-140 watts per channel, you should be sending sufficient power to the speakers. We hope this helps and please let us know if there is anything else we can assist you with. We appreciate your question and support.

Hands down the best speakers I’ve owned. Currently using these speakers as left and right channel and these speakers are beautiful as well as sound great. Great mids and highs, however due to being thin they suffer when it comes to bass so make sure you have a sub. Installation was fairly simple, considering this is the first time I’ve installed any speakers on a wall. The only thing I wish as that it allowed the speaker wire to run down rather than on the side. Recommend having another one as a center, or even a Motion SLM. If you’re looking for great sounding speakers that take up no room then these are your speakers.

These are really nice looking and great sounding speakers. I love the slim profile with them hanging on the wall. I use this one as my left and right stereo speakers. If youre using these as stereo and/or center channels, you need a woofer. The sound clearity is amazing but there is very little bass out of them. Dont let my photo deceive the size of the speaker. I have an 85" tv in the pic.
