Edifier Speakers (bluetooth) r1850db with subwoofer out

These bookshelf speakers are Ideal for plugging in to your TV with the optical cable or your TV, PC and phone via bluetooth or dual RCA to 3.5mm audio - USB-C (not included) for an even better quality sound, especially with Looseless. No need to add an amp as there already is one built-in. It also has a sub out in case you wanted to add one. A brand new connecting cable (5M) and brand new optical cable are included with the remote. No scratches and still has a great quality sound; I assumed it will only be better with the new cables. I also have an extra 3.5mm male to 3.5mm male although there isn't a plug for this model. Retails for $329+tax.
