The Polk XT20 Bookshelf speaker seems to take a few ideas from the JBL A130 using a similar waveguide. From what I've seen of recent reviews, Polks have measured flatter than they did in the past few years. It's listing at $250, but is on sale for $200 at Best Buy putting it securely in the budget line.

Review is now on my site.
I was expecting a lot worse. It looks like a 2 Ohm resistor inserted right before the tweeter positive terminal would smooth things out quite a bit. What remains is the directivity issue. Do you think that would still make these a non-starter?

Yeah, I was thinking the same thing - padding down the tweeter a few dB to eliminate the rising response above around 2000 Hz.

Dayton could have designed the crossover to not have the elevated response above 2000 Hz, right? Wonder why they went for the elevated response?

Also, I noticed that the manual indicates a 2000 Hz crossover, but the webpage says 3300 Hz.

All-in-all, for $150/pair, if they did not have the elevated response above 2000 Hz, they don't look too bad.

Definitely not the worst I've seen. Distortion performance in particular seems surprisingly solid. Directivity is kind of a mess, but I think at least some of that could be mitigated by redesigning the crossover.
Would be nice to see the Focal Alpha 50 Evo. I would like to see how the cheap Focals perform! :)
I saw some gated in-room measurements from a Korean site that @napilopez digitized. It's overall pretty decent, and if the measurer's distortion measurements are accurate it's very low distortion as well - better IMD performance than even the KH120.

Yea, it's not terrible but - being they (Dayton) have access to all the parts they'd need to make this better - I am disappointed. There is no reason for the HF to be lifted +5dB as it is. And then you read this on their site what I've provided below and it's just... well, honestly, annoying. IMHO, it "primes" the customer base to think that artificially lifted treble is "detailed". As someone who is doing their best to provide data and help people understand the importance of a neutral response with good directivity, it makes my job harder (hopefully that doesn't sound like I have an ego about it; that's not my intent). Then there's the "you don't need a sub" bit. Meanwhile, the data shows this isn't the case with an F3 of 72Hz and F10 of 43Hz. Those numbers are indeed good. But is it "subwoofer" territory? Certainly not. I feel like Dayton's marketing department took this speaker and ran with some outrageous claims.

Sorry, I didn't answer your question above.

My opinion regarding the directivity error as it relates to the shallow LPF of the midwoofer is it seems like they may have used this slope because of the cabinet resonance(s). If you look at the nearfield responses you can see there is definitely some port leakage and this is most likely the cabinet resonance. I say that from the perspective of having tested a handful of smaller speakers over the past two months and finding similar resonances and confirming they're due to the cabinet resonance via an accelerometer. I can't help but wonder if Dayton said "hey, we can save money on components and use the resonance to flatten out the response". Or... maybe they didn't. I'm trying to give them the benefit of the doubt. Still, that doesn't fix the directivity error you asked about which, IMHO, is pretty severe as it spans a couple octaves. @pierre's results put the preference score for this speaker goes from 3.2 and with EQ it goes to 6.2. Not that the preference score is something I always go by but in this case, I think it's worthwhile to mention because EQ doesn't account for directivity error. So, it is possible the speaker might benefit from a simple padding of the tweeter *but* I believe that for $2 in parts (Dayton's cost) that this speaker could have been a lot better and I'm surprised they did what they did here. I kind of always held Dayton in a higher regard but I feel like they caved to the marketing side with this speaker; especially considering the above screenshot of their website citing the "detailed highs" and "no subwoofer needed". :/

Oh, and FWIW, I know two others who have this speaker. One received them for review. One bought them. Both said the highs are unbearable.

Looks like a speaker that may be good at low volumes, but not high.

Amir, this knock off Genelec from Behringer could be a good one to review.
B2031A - $200 each typical price
You reviewed the discontinued passive version of it (I think): https://www.audiosciencereview.com/...behringer-b2030p-studio-monitor-review.14719/

Not only passive but also smaller, the passive equivalent was B2031P (both passives are discontinued).

I agree that the B2031A should be definetely measured here as other measurements have shown very good perfomance for a very small price and big size (8,75" woofer), it seems copying Genelec worked quite well.

Amir, thanks for your work,
Pretty sure some people are already suggested it but...
I would like to see Wharfedale Evo (some 3 ways... - 4.2?) - tested, wonder if its upgrade to Diamond series. Also some listening comparison to revel's would be nice :)
