Did I get the right Speakers?

[ORFF]

Receiver: Sony Strdn 1030

Center :Sony - Core Series 4" 2-Way Center-Channel Speaker
Model: SSCS8 SKU: 5720006 (best buy)

front right and left:Sony - Core Series 5" 3-Way Bookshelf Speakers (Pair)
Model: SSCS5 SKU: 5721014 (best buy)

Rear 4 Bose® - 161™ Speaker System - Black
Model: 161 SKU: 4151394 (best buy)

Basically I'm wondering if the receiver is good enough to handle these? Am I going to stress it or the speakers by having it up loud?
I just bought them and want to make sure they work well together.

I really appreciate any feedback. I'm new at this stuff and don't quite get stuff like this: 1015W (145/ch x 7 (8 Ω, 1kHz,
0.9% THD 1ch)

Thanks in advance for helping.

What that means is that they're claiming your receiver is 145 watts per channel x 7 channels when driven to an 8 ohm speaker (as opposed to a 4 ohm speaker).

However, they ran that test not across the whole frequency range, but only with a 1 Kilohertz signal. The total harmonic distortion is 0.9%, but the tests were run with only 1 channel being driven. When all channels are driven (as in a big scene in any movie that has sound effects, dialog and music score all at the same time), the power output would be far less. And even with only one channel driven, at high frequencies or at low frequencies, the power output could be far less (which is why they only quote at 1KHz.)

Not that it means the receiver is bad - my old Crown D60, which output only about 30 watts per channel sounded far superior to my modern high-end A/V receiver that claims much more power.

In the hi-fi industry back in the day, there were standards for this implemented by the IHS (Institute for High Fidelity) and they used to have to quote RMS wattage, all channels driven, 20 to 20KHz at a given level of distortion. That was a far more honest methodology. The auto industry didn't follow that, so they'd do something like claim a receiver was 100 watts, but that was peak-to-peak wattage, so it was 50 watts peak, 35 watts RMS, 17.5 watts per channel, but only 12 watts when all channels were driven and 9 watts with under 1% distortion.

So the numbers can be very easily manipulated.

Having said all that, simply listen to your speakers. If you like the sound and they were within your budget, then they were the right speakers.

Any receiver can handle those tiny things. Is your set up in a BEDROOM!!!.
You might get away with small family room with volume not too loud. You have to find bench test on that receiver to see how many watts 5 channels, also
it does not have pre-outs, so if in the future you get better speakers and you
need to hook up a power amp to drive them you would not be able to. Those
speakers you have are not going to sound good in my opinion.
