In Reply to: RE: a 3" driver besting a two way design in a bigger cabinet? posted by 3db on February 27, 2021 at 21:37:45
Allow me to play devil's advocate and indulge this 3" driver thing.It's a single driver.
You can't get less crossover than a single driver with no crossover. You're connecting the amplifier output state directly to the speaker terminals. People spend $25,000 on a pair of Neo-magnet 8" fullrange drivers. They then connect the amplifier output stage directly to the speaker terminals. Bliss ensues.
But every "fullrange" speakers has, in effect, two "crossovers" (or filters) associated with it - not electrical per se, but mechanical. The first is the low end rolloff and the the second is the high-end rolloff.
A full range speaker is actually a band-pass device. It can't do 20Hz well any more than it can do 20kHz well. And by well, well, I mean well.
So does a 3" speaker in a clock radio trump a 3-way with an exhaustively designer crossover and cabinet? If you're a single-driver officionado, you might actually say yes.
And that is all I have to say about that...
Cheers,
Presto

that would fall apart rather quickly in a blind listening test. A 3" driver cannot do bass, cannot do midbass, can do midrange and lower range treble but cannot do upper range treble, especially those stuck in a clock radio. Its purely sight bias and has nothing to do with actual quality of sound.
I was saying that a full-range speaker is governed by the laws of physics, making it a glorified midrange driver with a high and low pass filter built into it, inherently. (Mechanically).
Freaky whizzer cone breakup to get "up to 20khz" notwithstanding...

I understand that mechanical limitations makes it sound like a glorified midrange driver but the quality of midrange also sucks. If one prefers that sound, Im saying that the only reason why that sound is because of sight bias and not because it actually sounds better.

Turns out I was just being sarcastic that day.
But I did not suggest that a clock radio speaker would "do midrange well" - I merely poked fun at single-driver aficionados who would make note that it's a single driver connected to an amplifiers terminals.

Thanks for that comforting post. I made a pair of 7x 11 cabinets for 5 inch Dayton Audio full range drivers bought on sale for $40. I am somewhat proud of the sound. This started me thinking on going for high quality drivers, perhaps costing up to $200. I gave up that plan when I saw the Zaph SR71 drivers for around $400 which is loved by audiophiles.Then the idea occured to get one driver of very high quality for $400. My friends cannot accept the idea of going back to mono. So the dilemma. Decisions! Also this lock down and such. Afraid of vaccination too.

of both Moderna and Pfizer. We are all feeling great , and I am the only one who had a slight fever and nausea for one day only. That is a normal reaction of the immune system, which is a little more sensitive in me who has had hives in the past. I wouldn't be nervous about it.
Once a large majority of us get the shot, the sooner this virus will be subdued and we and the economy get back to normal.
And like I said, I love my stock Tivoli. I even have the original KLH, but it needs restoration before I can compare.
Ah, how I loved the KLH radio playing WNEW of NYC. I still can hear the Byrds singing Turn turn. Tivoli has the family traits.
Cheers

"Turn, Turn, Turn" by the Byrds used to give me goose bumps in my folk rock days. Eveyone on this site is so different in their "goose bump" recordings.
