I am looking for a small sub woofer and a pair of smallish full range speakers, bookshelf speaker type of size that can be wall mounted rather than floor standing ones

The full range speakers just need to be able to handle 100W, the sub woofer really doesn't matter that much as with it being a semi detached house I can barely turn it on anyway

Not an audiophile so not looking for ones that would require me to sell a kidney, just something "ok" at a reasonable price for a surround sound system
