## Questions & Answers

**Q: Hi, did anyone found speakers parameters to build cabinet for 8" sub? Thank you.**
A: I found the specs *thiele small parameters" for this driver after a bit of luck and a lot of searching. Assuming you know how to use these they are:
FS: 38Hz / Qts: .54 / Qms: 7.1 / Qes: .58 / Vas: 22.6 Litres / Sd: 218 cm2 / Mms: 50.5g / BL: 12.2 / Xmax: 5mm
I have put these is a 40 litre cabinet tuned to 38hz. QB4 alignment suggests 36 litres, but 40L will allows for port, bracing and driver.
it's a big box but wow the bass is crazy. These are possibly one of the most under rated drivers I have come across for a while :)
I made the cabinets using a 36mm mdf (2 x 18 mm sheets glued together) and heavily braced. 
I have another pair as main speakers for the home theatre with a tweeter. They also extend quite well into the mid range and with a bit of cunning in the crossover network you can get these to sound surprisingly good. - no subwoofer needed.

**Q: I have a 50W*2 and 100w sub amp, would this be a good subwoofer to use for it? I know you should match,I'm struggling to find anything below 500w rms**
A: For the price this unit is excellent all round, but I would suggest it needs more power than 2 channel (2x50W) or singe 100W. I recommend 100W RMS amp at least per speaker to get these drivers going properly :-)

**Q: Are these mid or low range?**
A: I have the 8" and it's very definitely a sub/low range, I think the 5.25 will drive low with the right crossover but I would class as a mid.

**Q: what is the output of each unit in terms of watts- RMS ?**
A: 250 Watts RMS,max is 500. That manufactor their website.

### ⭐⭐⭐⭐⭐ For the price - UNBEATABLE!
*by A***R on 16 May 2017*

I have had many of these over the past 6 years or so.. not because they have broken, but because I always seem to find a project to use them on! I have found that these things are just amazing for automotive use. I bought my most recent pair to use as midbass door speakers in my custom build. I originally had some Ground Zero reference drivers installed but my friend put his foot through one getting in the car! I didn't want to fork out for another set of those! The system is ran though a DSP and each driver is amped at 100 watts, crossover set at 50hz and 8khz with a 12db slope so the subwoofer and tweeters take over. I found drivers only needed a small amount of EQing to even out the response. Overall I am so impressed with the performance and sound quality of these drivers. They are installed in custom door cards with a ton of sound deadening and proper sealing which helps bring them alive! As long as you don't overpower or under power them, get the crossovers right, take some time with positioning and placement they will surprise you!
