Wow KEW, you put a lot of effort into discussing that graph, many thanks! I learned a lot from reading your post. Sorry about the -50db, I screwed that up by using the scroll wheel and I didn't know any better.
So let me focus a minute on the super-shitty laptop speakers. Those are "Bang & Olufsen" speakers on a $1,365.39 HP Envy laptop. Let me tell you, I have been a loyal and satisfied HP laptop owner before buying their modern overpriced trash. They have really wh*red out their name. I was literally SHOCKED at now shitty this laptop was compared to my last 2 similarly priced older HP laptops. The speed is like 8% of my old laptop (verified with speed tester), the hard drive failed in less than 6 months. It has warped plastic that never fit, the keyboard keys protrude, etc... F*** HP. My long standing loyalty has been r*ped. They took a $300 grade laptop and gave it their top-tier pricing and advertising.
So back to audio.
I took the same data and re-scaled it as you recommended, in case you are interested. This time with 1/24 octave smoothing.
I like that you are the second person to recommend the RSL system, that's a good sign.
I like the factory refurbished route for the receiver. I might just order one today.
I will be having some fun with a DIY speaker next month, but they won't be for this system. I have a cool design in the works with the perfect amount of sealed space behind the speaker. The 3D printer makes getting everything perfectly placed easy. That speaker will be a Dayton Audio ND-65-8, but it's on back-order now.
