Budget speaker test Dayton Audio B452 vs. MK402 (with audio sample)

I wanted to see how big of difference there are to these low cost mini bookshelf speakers.

Thank You!
DAVID GREGORY KERR : If they had gone with powered speakers they could have had a two DSP processors doing the work of the filter networks inside the speaker cabinets plus PWM output stages for the Woofer and Tweeter maybe that would have been better.
EspHack : I've been wanting to buy a pair of MK402X or micca mb42x for a while now, I currently have an old AIWA stereo paired with a sub at 80hz crossover, the AIWA speakers are 6ohm, ported, 4" woofers with no tweeter at all, but the cabinets are huge and heavy for some reason, I wonder if the MK402x would be a noticeable upgrade?
vaughn tonkin : Hey John, have you considered the micca speakers? the base model is one cap X over and the X model has 9 part X over 12dB with zobel across the woofer, I have the base model and it sounds better than Polk T15, the Polk's treble too flat and 130Hz honk, the micca's have the same tweeter as the 402 but is 8 ohm and the micca woofer is 4 ohm hence the impedance on the micca says 4-8 ohm
joshua wang : MK402 is way more better than B452. it sounds better in every way, fuller, balanced, more freq extension,
Ruben Torres : I need a pair to replace my Optimus speaker!
Automation Academy : Thanks for sharing your knowledge very informative, it
inspired me to focus more making electrical video
Chris Harper : I bought a set of the B452-AIRs for the TV and they are dreadful. They were so bad that I pulled the drivers out, made my own cabinets and crossovers and still not very happy with them. Those woofers look just like the RS Minimus 7's but with a poly cone yet they're worse. AMT tweeters seem okay.
Car Rizzle : The capacitor doesn't block the meter from reading the resistance. Capacitor have an ESR (Equivalent Series Resistance) rating and is shown in parallel with the speakers resistance thus giving you the total resistance of the tweeter. The speaker resistance is a combination of the woofer and tweeter resistance together giving you the total resistance.
And 6 ohms is a speaker rating nowadays. Just needed to spread some useful information.
But good video.
AcousticTheory : The B452 was one of my products when I worked for Parts Express. It's quite limited, which should be apparent, but we (myself and another engineer) spent a bunch of time working to find the right balance between the tweeter and midwoofer, and the right capacitor value to blend the tweeter to the woofer, and we relied heavily on listening tests. (The MK402 was after my time.) It was a fun challenge to try to make the least expensive product possible that would have acceptable performance for many people, but it doesn't claim to be more than it is - a compromised, cheap speaker. We were aiming for a smoother and more natural reproduction instead of a biting treble or boxy, colored bass range which some cheap speakers have. I don't know if any changes have been made to the B452 since I moved on. The MK402 is intended to be a nicer speaker, obviously, and it has a lot more to offer, but still at a slightly higher mass-market price. Its 4-ohm load is actually a good match for the small Class-D chip amplifiers that have become widespread in the last 10 years.
James Palmer : The mk402 reminds me of Bose bookcase speakers.
