Thanks for your reply. I'd like to try those salad bowls, did you make a sphere out of them? That little driver has decent excursion.
Haha, yeah good description, I would think something like that would happen eventually. 🙂
Thanks, I wonder if those that like large drivers, perhaps with whizzer cones, are on to something.....
Well, as already spelled out it depends on a number of variables, but the bottom line is how much distortion folks find acceptable and never cease to be amazed just how much many folks will tolerate if perceived as euphonic such as is common with high output impedance tube amps or later lower output impedance tube or class A amps with +20, -15 dB bass boost and certain driver designs such as curvilinear profiles that do a decent job of ~preserving its HF timing while its lower fundamentals, harmonics below our ~<250 Hz acute hearing BW is being 'stretched' over time with increasing excursion.
I use 10dB bass boost with a Linkwitz transform filter for my Tangabnd 3"ers (W3-871). These are my PC speakers, so listening position about 60cm from the speakers. They still play plenty loud with 2x 1W due to the proximity.
An it's certainly not a band aid - speaker is a totally different beast when equalized down to ~50Hz instead of the un-EQd rolloff at ~120Hz.

Hi Jazz Man, yes I did. Managed to find two pairs that were a decent match, sanded the rounded rim flat and glued them together

Is there much difference in size? I'd get mine mail order so it would be pot luck, thankfully any step that far round the enclosure wouldn't be an audible issue, more cosmetic. They are made out of bamboo which is supposedly quite a good material for speaker cabinets?
I use a Tripath TA2024 amplifier which is fed by a 5V to 9V DC/DC converter with 2W output. The TA2024 goes into undervolt protection if I push it too hard (DC/DC converter looses voltage), so I definitely cannot go above 1W per speaker.
with 1W the W3-871 probably make an Xmax of +/- 0.5mm, maybe a tad more (cannot measure that). It should be in spec. And no, no audible distortion problems in the bass range. The speaker is not the cleanest regarding distortion but that's more audible in the critical midrange frequencies and even at levels way below max. It's certainly not a high end driver but it has given me countless nights at really enjoyable listening levels and with a lot of pleasure so far! Bass is very dry (Q is tuned to 0.5) and not earth shattering but still astonishing for such a small speaker. As you might have guessed by now, I really like these small beasts 😀

Not per se. Link? Understood, just added a couple of very common issues WRT to 'FR' systems in particular that I didn't notice in a quick scan since I currently don't have time to do much more with knowledge intensive threads, so if already discussed, never mind.
This is not totally unreasonable but why not adding sub instead? $60 sub from Amazon will not sound better?

Ah, sorry, I mentioned and linked to it earlier in the thread, here you are Doppler Distortion in loudspeakers
Doppler distortion makes sense. But 2 of 3 texts i have read on human hearing say it is not really of concern.

I think IMD is probably of more concern, this is an interesting post hhttps://www.diyaudio.com/forums/mu...istortion-doppler-distortion-post4697123.html
Thanks! Harks back to the referenced PWK paper I read way back when, though while my 'knee jerk' response was IMD, need to 'refresh' my mind before doing any more of this type response.
Overall, looks like frequency modulation distortion [FMD] is the most technically correct description and seems reasonable it's the 'biggie' for wide/full range drivers in general due to doping, generally increasing stiffness as it approaches the VC junction.
