Hello, I don't have much knowledge about receivers or home audio setups in general. In summary, I need help with 1) picking an receiver, and 2) picking out connections. Please pardon any mistakes I make.
Recently I purchased a nice TV, and decided to use the surround sound system that came with the house. There're 5 speakers in the ceiling arranged like the following looking from the ground. They are already installed, and there's almost nothing I can do to change them. The speakers are already installed in. The room isn't huge, but it isn't small either. From center to either left front or right front runs about 6 feet. (So, left to right runs about 12 feet). From the front to rear runs about 10-11 feet.

(front left) (center) (front right)
(surround left) (surround right)
I'm guessing the setup is 5.1, but the center ".1" part is missing. I'm guessing that's missing because that would be the subwoofer (?).
The previous owner was kind enough to leave the instruction manual. All I know to interpret is the model information: 6.5" Sonance Symphony Series in-series speakers. In the instruction manual, there are also specifications for four different models. I don't know which one these speakers are, but these are what I see that are relevant. I unfortunately don't know which one I have.
624TR 623TR 622TR 621TR
Freq. Response: 38Hz to 20KHz+/-3dB | 40Hz to 20KHz+/-3dB | 45Hz to 20KHz+/-3dB | 55Hz to 20KHz+/-3dB
Impedance (Min.): 6 ohms (4 ohms) | 6 ohms (4 ohms) | 8 ohms (6 ohms) | 8 ohms (6 ohms)
Power Handling: 5 to 125W | 5 to 100W | 5 to 75W | 5 to 50W
Efficiency: 90dB @ 1W/m | 89dB @ 1W/m | 89dB @ 1W/m |88dB @ 1W/m
(How are these speakers?)
This is the output found on the wall (behind the TV).
I'm assuming what I need is a receiver for this to work out. Is there anything else I need besides the cables?
What kind of cables do I need? (What are these outputs called?) Does length and gauge of cable matter? I know that I won't use more than 2 feet of cable per connection because they're right behind the TV/stand.
Basically, I'm completely lost. Just need to have some insight. What do you guys recommend for an receiver/AVR? I do want some future proofing.
Thank you all in advance helping out a newbie.
