Need advice to buy better speakers

[Ali]

I don't think speaker quality is a really important thing, if you is using masked it is alright to use any kind of speakers including laptop speakers as long as the sound doesn't sizzle, Shannon said this sometimes. And if it is ultrasonic it should be reach 20Khz or better frequency. I use cheap Creative Sbs A120 speakers. it is a good sound system and produces 40hz-20khz frequency they are right to my head when I sleep.
But of course when it is comes down to music, your system should be amazing I love high quality sound materials 

I think the main thing to consider is what your objectives are. If you are planning on using the Ultrasonic format then speaker quality is important. That doesn't mean expensive, but it does mean a speaker that has the frequency response range of at least up to 20Khz as Shannon advises. This doesn't mean you need to break the bank though as there are plenty of speakers that can achieve this. For me I didn't have any speakers at all apart from one bluetooth speaker (which I know would have not been good) and I also wanted to get a good reasonable set that would play music well too hence I bought some that were more expensive so I could achieve both objectives : Win Win haha.

Hope your journey is going well tolgacal80   good to hear from you
