Its amazing. The issue with the fast8 is that if you dont cutoff low frequencies from it, even tho they are much lower in db through baffle adjustments the driver is still impacted by trying to produce those frequencies and hurts the mids and highs because its a single driver.

Try building a big baffle for the bass driver and have a completely open 5" FR driver on top. I have my open FR driver on top of a bass reflex box with a normally mounted woofer. They are the best speakers I heard! They flog my B&W 706 bookshelf speakers (2 grand). I urge you to make them and test against the 15" FR speakers. I used $9 FR drivers and can afford to modify them. This is what I did. They roll off up top but I changed that by slitting the cone (right through) with a sharp razer blade. I made 8mm long cuts around the center (3mm out) right around, with 5mm gaps that are not cut. I repeated the process 1cm out. For the best treble I ever heard! 😅 I also removed the dust cap and whizzer cone (if it has one) so there is no enclosed chambers what so ever and also no out of phase whizzer. I also made cutouts on the main cone (right around a 3" diameter circle softly drawn on the cone). I made five 25mm curved cuts around the circle, with gaps about 12 mm long (that are not cut). Softly draw thin banana crescents outside the cuts so they start and stop @ the start of the cuts (width of the crescent in the middle is about 3-4 mm). This acts like a free edge cone! And it's still strong and you can crank it a fair bit (I have a 100 mf cap on the open driver along with a filter and a large inductor on the woofer about 300 hz crossover fr). And the voice sound is so confined! You can "see" their tonsils! It's dipole and holographic off the scale. You can hear everything. With the cutout it's not shouty and the med is so clean, defined and detailed and not a hint of resonance! Just completely clean and lush. Like an aluminium ribbon panel speaker but it's entirely cardboard! Crazy sound. If you make it, listen and close your eyes and try to imagine it's conventional 2-ways. Good for a laugh! For the start you çan't even tell where the speakers are (with eyes closed). Love your channel and take care. And remember, there's nothin' like dipole point source! ❤

I reckon class D has treble a bit like piezoelectric tweeters. I used those tweeters inside coaxial drivers and I made inductors with 20 winds of standard speaker cable around a pencil (and hot glued). This improved the "spiky" sound of the piezoelectrics a lot. So maybe try 10 winds on a class D amp so it sounds more like an AB amp (maybe).

@LeonFleisherFan

GM70 are among my favorite tubes. Whether copper anodes sound better than graphite or iron has a lot to do with the design of the amplifier (in the Amplifon, perhaps my favorite GM70 amp, the copper sound very different, but not "better" - actually I know at least four audiophiles who think it sounds worse, so much for tube aficionado opinions…). In general the "sound" of any particular tube is hard to discuss fairly because so much depends on the circuit in which it's used. GM100 I have only heard at trade shows (e.g. NAT). Any amps in particular you have in mind there?

Hi. Love your channel and your way of getting great sound at not too high a price. Just got a pair of new W15s to handle bass below 70hz via an active crossover, powered by a Hegel H120 ( 2 x 75 W into 8 Ω and stable at 2 Ω ). For some reason W15s are crackling quite easily on reaching peaks. I would have thought that these powerful speakers would easily cope with peaks and high wattage. Wonder if you could help me out or give some advice as you must have loads of experience dealing with these speakers.

Right now, its direct in the wall in the same circuit as the puritan and the rest of the components why? Because i ran out of outlet for all my gear so I prioritized the sources and upstream components in there over this amp. As if noise is coming in to an amp giving clean power to the amp will not make it better.

@@hificave Those are indeed factors though somewhat interrelated, for instance a weak magnet in a large driver will not have high sensitivity. The W15 is a high sensitivity bass driver, just a bit less than the full range F15, yet still needs far more watts than the F15. Which all else being comparable is what leads me to suspect that it is the bass frequency that is the determinate factor in why there is a difference. A deeper bass note requires a greater movement of air which takes more power, i.e. Watts. Test tones and a volume meter might well confirm or dismiss this factor. As, if a test tone of 36Hz requires turning up the volume to match the volume of perhaps a 80Hz tone, it would confirm that theory. If no change on the volume meter is seen, then we have another theory shot down in flames ;-)

I'm confused! With the Fast 8 rolling off at 200Hz, why would you have the F15 starting at 250Hz? I would have been more inclined to set at say 150Hz, then take measurements even with a simple phone app to see where they are summing and alter so the point where they crossover is flat. Only jumping in at 250Hz you are going to have a lump and likely some cancellation as well.
