So Far I Did Not Check, I Got Everything, The Delivery Is Fast, I'll Check-I'll Add It. 27 Jul 2020 12:02

S***v from RUSSIA

Ordered On April 30, Arrived On May 18, Shipped Was 14, Like 4 Days, But Csuka Almost 3 Weeks Shipping, If Shipped Immediately As Ordered, Nace, The Box Came Slightly Minted, Stocked On 2Ku Little Protection For Such A Product, Any Static, Large Weight, Could Not Hurt So Spoil The Fee. Playing Slaughter, When Connecting Bluetooth There Are No Sounds, Took For The Project, The Very Thing I Was Looking For, Very Glad, Did Not Open That There With A Thermal Paste, But So I Understand You Need To Pour. Slightly Slowing The Sound From The Connection Of Saba, Delay Eaten Noticeable Ear, But Stresses, May Cause The Sound By Bluetooth, But On The Wires Will Not Make Connection And Check. 19 May 2020 03:36

Norms. Krutilki Soft, When Adjusting The Volume, There Is No Noise Or Movement Of The Speaker Membrane (unlike Some Cheaper Analogs). In Silence, The Hissing Is Very Quiet, With A Volume Increase Slightly Increased, It Is Not Heard If You Do Not Listen. Default Bluetooth Mode. Delivery From Russia, A Box Came Up For A Week. Cons: When You Turn On The Speakers Crack Regardless Of The Position Of The Volume Handles. When Switching To The Mode Of The Line Input, The Baba Speaks In A Eager Voice Liin Yiyin. The Rise Of The HF Affects Only The Right Channel, Which Is Visible On The Charts In The Third Photo. 05 Jun 2020 12:01

Packed Perfectly, Came Quickly-in Two Weeks In The Lipetsk Region In Conditions Of Coronavirus. Connected To Check 2 Speakers Without Subwoofer, Power Supply From The Same Seller, Everything Works, Everything Is Adjustable, Music From The Phone By Bluetooth Plays, When Connecting/disconnecting By BT Quite Quietly Picks, No Chinese Words Say, It Is. When You Turn On The Network, It Pulls Loudly From The Columns, It Is-. Between The Radiator And The Chips Was The Finest Layer Of Thermopaste, Twisted The Radiator Was Weak, But When Trying To Twist Stronger Everything Bends, So Do Not Pull Hard 11 Apr 2020 04:48

There Are Little Damage. Apparently Traces Of Transport. Or Bad Miscarriage. Otherwise, Everything Is Fine. 25 Jul 2020 06:32

Very Good Amplifier. Works Better Than Options From Competitors With 3 Handles And 1 Small Radiator. There Is More And More Quality And Dissipation Area. Decided To Change The Amplifier Inside 5.1 Sven Ha-1410t. Make It Pure 2.1 Instead Of Native 5.1 As The Amplifier Is Noisy, Humming Even After Repair And Replacement Of Capacitors. This Model Can Be Advised To Buy. I Attach A Photo Of The Competitor. 13 Jun 2020 01:32

M***v from RUSSIA

Minus Only One, When Turning On A Very Strong Second Crack From The Speakers, The Volume At 0 A Sound As If At The Maximum. On Large Speakers Have Not Yet Checked, But On Small Plays Decently. Powered Both From 12 And From 24 Volts All As Stated By The Seller. Everything Works! Thank You! 09 May 2020 08:01

N***h from UKRAINE

The Product Works Great. Shipping Fast. 50w Bass Speaker Is Insufficient. It Can Open Up To Half. The Only Problem Was That The Potential Meter Had No Nuts. I Had No Trouble Because I Had It. 12 Jun 2020 13:52
