## Questions & Answers

**Q: what is the frequency range on this driver**
A: 50-4500hz is probably a good estimate. This is one of my all time favorite drivers because it covers such a broad range.  You will need a tweeter for this driver, but the amazing thing about it is how low it reaches and how clean the bass stays.  By that I mean the harmonic distortion is kept to an absolute minimum within the specified frequency range.  However you will need to have a low pass on this to avoid the cone breakup above 4500hz which is quite sharp

**Q: What is the maximum wattage this thing can take?**
A: I don't have the specs, but I recall the speaker was rated at 25 watts RMS.  Search online, I recall a Chinese company had all of the specs listed.  BTW, I was running them through an amp that was rated 60 watts RMS a channel and that didn't blow them out.

**Q: Is it sold as a pair or single**
A: Single.

**Q: Do you combine shipping if I buy two?**
A: Our pricing is already based on someone buying two.

People getting sued for gouging on hand sanitizer, but it's cool to charge double for speakers.... The speaker itself is great, I just had one damaged by kids...
