At one time I recommend these Edifier bookshelf as cheap audiophile speaker, but after self tested at Harvey Norman store on the R2700 model, I feel disappoint with the speaker.
I connect the speaker with the provided 3.5mm audio jack input to my phone.

I set my phone output to max, and the speaker volume to max. The speaker is very low in loudness, feel like a flawed or defect unit, rather than how it's look telling.
Being the speaker this big in size, it should be very loud, but it very very muted.

I recommend better check in person for the speaker unit before buying.
