This is a budget gem! It looks like an OEM version of the 830855 (which is 8 ohm), with an extended pole piece for longer throw.
Thiele-Small parameters all match the datasheet out of the box but the compliance, which is lower; i guess it's normal since i tested one of them before actual use, so a burn in might soften the suspension and bring cms to the stated value.
I paired it to a LaVoce TN100.70 in a 2 way bookshelf speaker and in a portable ammo-box speaker. The bookoshelves are made out of 10mm MDF with lining on the sides, the enclosure is a 5L bass reflex tuned to 48Hz, and the bass is amazing for the size, it reaches easily 50Hz and goes even deeper. Midrange is also good, with the filter i made.
The ammo-box is a very cramped 2/2.5L net volume with 5mm mdf on the sides; i turned it into a bass reflex enclosure tuned to around 72Hz, it doesn't have the deepest bass but it's punchy enough for a portable boombox.
The excursion is really big with little distorsion, i think the 5mm xmax is realistic. No mechanical noise.
Overall it's a gem of a speaker for cheap projects, similar to the Dayton Audio TCP115.

Very good, I use it in a 5 liter cabin, with the Peerless DX20BF00-04 tweeter, I should make a bigger one for 2 such woofers. I highly recommend it.
