Great video, I enjoy watching your channel! One comment about the B&O speaker, it should really be viewed as a 3-way speaker, with the 4-th driver acting as a "phase-link" - it fires in a narrow band with a peak at the crossover frequency between the woofer and the midrange, which are connected in phase. This technology was called "uniphase" by B&O, these speakers have linear phase response, are time aligned and transient perfect.

I've also done 45'ish years enjoying music, first as a low'paid electrical technician apprenticeship (£8:09p / week at 1'st) ... listening through s/h speakers (& s/h vintage valve amps in my first 25 to 30'yrs (of real hi-fi) at cheap pre-eBay prices from local ad's & that old mag' "Exchange & Mart") I'm 65 now & bought my 'better' own hi'fi gear from 20'yrs old &+ when I had my first flat. I've owned many speakers from always looking to improve my sound. I remember that IMF monitor (I once couldn't afford s/h but bought the more affordable s/h 3-way KEF Concertos instead & later, a pair of Cambridge Audio (?) ...but tall slim f/standers with vertical grooves in their black grills ...gr8 sound! & i think with the same drivers as the KEF's Concertos. My point is about driver materials, paper woofers / woofer-mids always sounded best to me (tho KEF B139's flat-faced racetrack shaped woofers were gr8, with their polystyrene (?) type of diaphragm construction) Older Metal dome tweeters i heard were not often smooth but more often brittle. And my biggest driver hate of all is: Polypropylene woofers & woofer-mid drivers, no matter who made them, all the polyprop' driver'd speakers I've had or heard, all had an annoying cuppy colororation to their sound, esp' in the lower-mid but throughout. The Mission 770 'Freedoms" had that awful polypropylene coloration & I don't know why hi-fy mags rated them so highly. And I always enjoy your videos.

I would vote for the 3 ways I've owned over 2 ways I've built... Our main listening room has a pair of 3 way 10 inch Dyna- Audio kits (built 30 years ago from Meniscus audio)....I reconfigured them in a smaller formant replacing the woofer with 6 1/2 inch....Driven by a 90's Adcom system they punch base push midrange with crystal clear highs Recently built the Hivi DYI 3.1 with upgraded crossover from Amazon...Yes these little speakers do deliver in all aspects...Highly recommended....Though both sets are small configuration they keep up with my 70's ESS/Canton 10 and 12 inch in punchy bass and sparkling highs....Yes, size does matter, but contemporary smaller drivers with quality crossovers and aligned cabinets can make a huge difference....

In the 2 way speakers the woofer manage bass and mid-range, but when the bass moves the woofer it creates a Doppler effect on the mid-range sounds that turns a bit confused or un-focused that mid-range, but the more ways or components the more trouble at the crossover transitions, there were in the 70's a speaker with 5 ways but with a very good crossover design that you didn't notice those crossover transitions that was the Dahlquist DQ-10. One of the most clear mid-range I have heard was the B&W 802 S3 with it's Kevlar yellow mid-range, the only coloration of that speaker I found was in the upper bass due maybe to the need of a bigger bass box volume I'd say maybe 20% more volume to the bass twin 7 inch woofers, but forgiving that coloration at around 150hz that is a faboluous speaker. Another low colored speaker was the JBL L-112 On other side the Martin Logan's but they are roll off above 10khz and as I can hear to 13 khz I find them incomplete due to that 10 to 13 khz roll off but in the mid-range are excellent. On early 80's Canton from Germany made incredibly musical speakers for me much better than those Rogers, I remember Canton Plus S and Plus Beta active subwoofer they were super musical, now I don't like Canton's modern metal cones and speakers, those of the 80's was wey better.

@@stereoreviewx The first mirror image speakers were JBL L-112 on 1980 as an improvement over the L-100 which was not mirror image pair. Since then every speaker design that do not employ mirror image design is a big mistake, this only apply when the voice coil of drivers are not inline. Because it affects the image and soundstage capabilities.

There are some great two way speakers out there. However they always come with a compromising factor. In essence though, they only come in two varieties. Speakers that really only deliver high frequency and lower midrange, meaning they are totally dependent upon porting, and strategic placement to produce reinforced bass. Or, secondly, speakers which deceive the ears by forsaking midrange altogether in order to produce convincing bass and treble. The inescapable truth is, there really is no substitute for a decent, emphasis on DECENT, three way speaker.

JOHN Heisz on his audio chamnel also argues that it's just the cross over and I agree. There's this general perception metal domes sound brighter but this could be manufacturers playing to that perception and make it sound brighter. At least if the resonance frequency is outside audio range and the infinite baffle response is reqsonably flat.
