Inexpensive but decent 8" subwoofers

SVS does not make an eight inch sub. Emotiva Airmotiv se8 flex subwoofer, currently on sale. REL Acoustics Tzero MKIII is the one ☝️ you should check out for the best quality. 

Take a look at Tekton 2-10 or 4-10 subs... sound great and look awesome.

The SVS 3000 Micro is worth considering…

I concur that the SVS 3000 Micro deserves a look.

It combines two horizontally opposed 8" woofers in a compact, attractive package which i was able to fit under a buffet used as my stereo cabinet.

I bought one a few months ago and then added a second one more recently, which I think balances the bass in support of a pair of K-horns.

A mobile app is handy and I can attest that the current customer support is good.

Thank you all for your suggestions.

So based on the price range and the appearance, I have narrowed it to the following ( in approximate order of price, low to high):

Kanto Sub 8

Jamos S 808

Monolith 8 

Audioengine S8

RSL Speedwoofer 10s MKII

Tzero MKIII

Sonos sub

Any of these that I should specifically avoid? Any of these that punch above their weight in terms of sound quality?

The speakers that I have are supposed to be "quick" and hence I was looking for 8" in the first place.
