Late to the party. For the price&look it is not bad.
By the way, @MZKM I think your scores for the 305P are wrong on your ranking lists comparing them to @edechamps 's scores, even taking the differing 'ideal' LFX frequencies used into account.
It’s only anechoic down to ~80Hz. They rented a larger one down to 20Hz and tried to make a calibration to their measurements lot make it also accurate down to 20Hz. However, it doesn’t work well at all and anything <100Hz should be ignored.They report as using an Anechoic Chamber. .https://www.soundstagenetwork.com/index.php?option=com_content&view=article&id=16&Itemid=140
It was @ROOSKIE not me.Then why did you warn that it would require a large inductor? For a 1st order (electrical) high pass you would use a large capacitor in series, not an inductor. I think you must have meant a capacitor, because that's what you're using in the schematic you linked. But even the 470 uF shown in your schematic would cause the bass to start rolling off higher than you would want.
But, the Point-to-Point bracing!
I wonder how the older 3020 performs.
Not so sure about that. Here's my little back-of-the-envelope analysis. Stay with me, I want your feedback.
Start with a tweeter 9' up. Sounds high, right? 1 foot from the ceiling. But when I'm standing in the kitchen 15 feet away my ears are only 3.3 feet lower. That means the down angle is only 12.4 degrees. I can toe them down by that much easily, let's say 10 degrees. So I'm actually about on-axis at that location. Of course, the vertical dispersion is critical to give as long a sweet spot as possible. Looking at the M106, the vertical is pretty smooth +/- 20 degrees, so, with a toe-down of 10 degrees, that gives me a cone as close to the speakers as 6 feet and as far away as I like. Horizontally, I can't get much closer than 8 feet anyway, with a 10 degree toe-in.
SPL is the bigger issue, but the M105 is rated to about 106 dB so I reckon 96 dB at the end of the room. OK, let's say 90 sustained. Isn't that loud enough?
Hi yes, that was me. Woops, yes I meant large capacitor. Really just meant that due to component costs it makes more sense for manufacturers to rely on the purchaser to attend to the monitors high pass via the AVR or EQ or some personal method, also allowing the user to choose the frequency.Then why did you warn that it would require a large inductor?

you are right on the money with rolling off the bottom octave hard and boosting targeted frequencies above that to fill-out a small speaker.
Interestingly enough, Radio Shack/Tandy used to sell a bass-enhancer which was an active LF parametric EQ with a low 20Hz filter (18dB/oct). It was sold specifically to work with their smaller speakers (minimus 7s etc) and was incredibly effective at cleaning up the low end from TT related warp and extreme LF from digital as well as providing useful and adjustable extension.

They are a very cool little product and frequently appear on eBay for nothing or close to it. It can make a minimus7 sound like a completely different and larger speaker.
I think there's a nice balance between low price and performance + looks. The new 3030i should be a good one. A lot better than this for sure.
Q-Acoustics Concept 40 owner here. Also owned the 2020is. What do you think is missing?I've tried Q Acoustics twice because of the great reviews. I've been disappointed twice. I like how they look, but something is really missing for me.
I had the much cheaper 2020i and Q ACOUSTICS Concept Center. Great finish. But... lack of detail, presence (won't talk too much, this is a measurement forum hehe). Never heard the Concept 40.Q-Acoustics Concept 40 owner here. Also owned the 2020is. What do you think is missing?

I had Klipsch also twice, wanted to like it, but also no love. Funny, that were the only brands i couldnt really like, 2 brands hyped very much. I've had Canton German speakers which were quite good and some I'm still using.That's funny: compared to my KG4.5's they seem almost clinical. Only thing coming from the Klipschs is that voices suddenly seem much more anaemic.
Oh well, it's all psychoacoustics anyway
