Default Mivoc subwoofers- low bass, great value; whats the catch?

http://www.mivoc.com/mivoc/PDF/AW200...nblatt_WEB.pdf

8" driver
fs 30 HZ
rms 120w peak 300w
4 ohm
35 euros....

speaker trade - mivoc - Einzelchassis - AW 3000

12"
fs 27 HZ
rms 180w peak450 w
4 ohm
49.00 euros.

Anyone used these? Can't understand all the spec as its in german but its mentioning passive radiators and BRs- wondering if it could be used in a sealed enclosure?

Tiny Vas, strong motor = small cab tuned high. Trade efficiency for increased cab Vb/lower F3 by adding series resistance to 'weaken' its effective motor.

8 litres... thats what I'm looking for, good performance from small sealed box

...except that this unit works much better in a BR!

I decided on a closed box around 40-45 liter netto

Whether its a sub driver or just a nice woofer would be a matter of priorities
I think of it as a woofer
49EUR is a very nice price

hello.
mivoc is a wellknown trademark in germany (see speakertrade/solingen).
there are two german speaker builder magazine's (klang&ton ,and hobby hifi) that worked out examples with this.............
k&t 6/2006 an active subwoofer called versacube (aw300 in 35 liter closed) with a hypex ampmodul....................
k&t 4/2006 a passive bandpass box (two aw3000 speakers front to front built in one vented box...........translation?)
and hobby hifi 5/06 and 6/06...........
greetings

When i modeled both, the smaller unit (AW2000) in a bass reflex gets a very good response with a box volume of 29 litres and a Fb of around 24. It drops slowly/smoothly from 100 hz to an F3 of under 30 hz, if I roll off (3rd order) at 70 hz or so. Great performance for such a small enclosure(if this is correct).

datasheet aw2000 in post 1
gehäuseempfehlung...........box recommended;
geschlossen.......closed (box);
bassreflex........vented (box);
basskorrektur.........bass corrected (with an amp);
diese gehäuseempfehlungen sind nur anhaltspunkte..........these box recommendations are only clues;

the examples are with use of an active bassmodule (am 80) and bass amplified +3.......+4db;
greets

They both look like nice drivers for a 6th order vented box. They will probably require passive radiators (because of the small box size).

The 8 looks like it would be good in a 15L box, tuned to Fs, with a Q=2 filter at Fs.

The 12 looks like it would be good in a 40L box, tuned to Fs, with a Q=2 filter at Fs.
