I am guessing they are all sold out for now. Nevertheless, the 10E offers more value (if you meant the 'new' speed woofer at 300$. Here is a comparison among the 3 diff RSL ones - https://www.reddit.com/r/BudgetAu...e_new_rsl/





That said, the KEF 10b compares to the RSL 10E - both are Class D 300 W RMS, 10" drivers. RSL is about an inch larger (about 16" cube) vs KEF being 15". KEF claims 24 to 140Hz (±3dB) while RSL is 26-200 Hz ± 3db. I would say the 10S MKII is a better buy for most people among all these, for say, a regular living room home audio setup.

Thank you for posting this. Here is EAC's review on the KF92 - https://www.youtube.com/watch?v=jmIB4saPQ3g
Besides the subs, Q150s are back to their 'normal' price of 350$ as part of this sale.
And there is one (?) open box Blade one meta at about 29K!

The RSL models are great value for the money and I would probably choose them over these KEFs. The best deal of the KEF specials is the KF92 which is a great choice for those that are looking for a smaller form factor. compared to something like the RSL models. Also the RSL models are generally pre-orders so that may not work for someone that needs a sub immediately.

I'd take the RSL subs over these all day long and twice on Sundays. Other much better subs can be had from Hsu, Rythmik, SVS, PSA, etc.

These KEFs are all SEALED subs. If your main use is movies/TV and you have a big room (esp. an open plan space) then PORTED subs (like the RSL) are the way to go, no comparison. To get similar performance as a ported sub in the same price range, you'd have to go with the much bigger and pricier 15, 18, or 21" models costing $1K-4K.

These KEFs are good if music is your priority and you are under severe WAF pressure to have something petite and pretty.

The only open box item listed in this sale is the KEF Blade Meta. All of the other items are new.

Bought thr kef 12" in March when best buy had on sale for 835 from 950. Kids watched monsters inc two weeks ago while I was in the room. Thought we were having an earth quake! I'm very happy. Goes great with my 2 R7s.

The WAF is real!

I currently have a 4.0 setup with JBL A180s as my mains. They do a decent job with low-end, but I'm ready for a dedicated sub. This is an entry-level system in my living room; open floor plan, but small-ish 1,500 sq ft home.

Recommendations for under $500? The RSL 10E is attractive at $300, but this is gonna be mostly for movies. Was considering springing for the 10S mk2, unless anyone has a better recommendation.

The only competition to the 10S (you'll have to be patient though, since RSL has shifted to a batch-order system nowadays) is the Monolith M10 but only when it's on sale for $450-500. Regular price is $650. However, Monolith/Monoprice has seen some complaints about after-sale customer service issues which much smaller subwoofer-specialist companies like RSL, Hsu, etc. don't suffer from, so there is a little bit more risk in terms of keeping fingers crossed that you don't get a lemon. Otherwise, you'd have to wait until around Black Friday when SVS usually puts its first gen PB1000 or older discontinued PB12 on sale for $400-500.

Kef fanboy here. I have the Kube 10b and the KF92. The 10b is a good, not great, subwoofer. It's good if you need some low end for home theater, but isn't a real powerful or deep bass. I replaced it with a JL fathom 13" and moved the Kube to the garage gym (along with my LS 50s).
The KF92 is a great little unit. Powerful, tight bass with great response and detail in low and high levels. It's in my audio room and I don't plan on replacing it anytime soon.

This is incorrect.

I reviewed the RSL 10E on YouTube and measured it exactly 15".

I agree with you that the RSL is better value and I got 27Hz in my tests.
