Mackie Thump TH-15A is a powerful speaker that is light and can be used anywhere , and still get you a powerful sound.
What I like most about this product is the 300-watt class-D amplifier, and a 1" compression driver powered by a 100-watt class-A amplifier and also the phase-accurate electronic crossovers, time-aligned transducers, and digitally tuned EQ filters allow a high quality sound regarding the frequency vibration.
What I like about this product as well is the fact that this product is portable , easy to carry it anywhere if you're a traveling artist or singer.
I must mention the 400 watts of pure punchy power , a complex and great 15-inch high-precision woofer , a single XLR input , a great design that assures durability and a great look , 3 bends of parametric EQ with different mid frequency , 1-inch compression driver and a pole mountable.

My opinion about the value of price is satisfying , this product can be bought on amazon or ebay for around 350 $ , however the quality provided , the design that is extremely well made , is worth the money and even more.

Precision and quality of the sound is very pro , no matter in which range the speakers work , they do sound very rich and good , without any additional noise or bass trembling , and in the low register it sounds even better.

I've tried several models that are available on the market right now , however I always loved a high quality product that isn't expensive , it's movable , light , well designed, and this is exactly what I've been looking.

Knowing what I know , I would buy this product over and over again , mainly because of it's frequency response and light weight.
