## Questions & Answers

**Q: Is Carry bag or cover included?**
A: No, a cover/bag is not included

**Q: Picture says 2 inch tweeter, description say 2.5 ? And double 6.5 inch woofer means each woofer is of 6.5 inch or what? Please explain... Thanks**
A: The amp has two 2.5 inch tweeters and two 6.5 inch woofers. The tweeters are mounted in the top corners of the cabinet and the woofers are mounted below. I have been using this amplifier in our church for 6 months now and it’s a great unit. I have 2 electro acoustic guitars connected to it and use the Bluetooth function to connect my iPad for the backing tracks. The DI output is then fed straight into the mixer desk. Great value for the money.

**Q: would it be suitable for vocals and backing tracks in small venues**
A: Yes it would be perfect

**Q: How much does it weigh?**
A: It weighs about 8 kg. It is easy to carry as it has a handle on the side.
