How do the Mechano23 compare to the modded Pioneer SP-BS22 (Philharmonic AAM) ?
A current comparison point would be to the Philharmonic Audio True Mini, at USD380. Measurements above 100 Hz are available on their website. The Mini's response appears even flatter than the Mechano23. 4" woofer though!How do the Mechano23 compare to the modded Pioneer SP-BS22 (Philharmonic AAM) ?
Imagine if a better woofer was used.
Actually, in those cases you owe yourself money…But if you are building speakers instead of watching TV, taking a walk, etc. then that time did not cost you anything.
There could be some small effect depending on how much stuffing is used. It's used mainly to damp internal reflections, but if overstuffed, can choke the bass. Why wouldn't you just stuff it first anyway, it's such a trivial task in such a small box...?Slightly off topic but too simple a question to start a different thread:
Im trying to build a speaker myself now (got inspired by this thread) and i've a question about measuring individual drivers.
I have constructed a box but does filling make a difference when measuring the individual drivers? Or can I make my polar measurements without filling the box?
with Purifi 4" drivers and Linkwitz transform possible ?Indeed you can't get deep bass response out of any small speaker like this from anyone.

At the cost of efficiency and distortions. Something for something - can't beat rules of physicswith Purifi 4" drivers and Linkwitz transform possible ?
Deeper bass extension in a passive box of a given volume requires that you give up sensitivity. this means in practice a combo of a weaker motor and higher moving mass. Aka Hofmann’s Iron LawImagine if a better woofer was used.
we can trade sensitivity for more bass extension for a given box size (the Hoffman Iron Law). Our little 4” woofer in about 3 liters with passive radiators has F3 around 52Hz.Indeed you can't get deep bass response out of any small speaker like this from anyone.

is anybody selling this as a kit yet?
