## BASS Hz! Description
Built for car audio enthusiasts who tune by ear.

Test subs, amps, and enclosures with precise bass tones from 10–150 Hz, in the driveway, garage, or at home.

Dial in your sub. Find rattles. Set your gain right.

Generate clean bass tones from 10–150 Hz to test and tune car or home audio while using pure frequencies, not music. Built on Apple’s Core Audio engine for accurate, low-distortion tone generation.

Perfect for:
• Finding and fixing rattles and buzzes in your vehicle
• Setting amplifier gain and boost with precision
• Stress-testing subwoofers to find their best response
• Prepping and fine-tuning systems for audio competitions

Features:
• Bass tones from 10 Hz to 150 Hz
• Real-time frequency adjustment as you listen
• Five preset bass tracks included
• Noise Test mode
• Sweep Test mode (20 Hz–20,000 Hz)
• Fine-grained control for precise tuning

IMPORTANT — READ BEFORE USE
This app generates very low bass frequencies not typically found in music. Always start at low volume. Unmonitored use at high volume can damage speakers, subwoofers, and amplifiers. Know your system’s limits and monitor volume at all times.

## BASS Hz! Reviews in United States

### ****- "Nice app!"
Wish I could go above 100 hz to test front speakers cutoff. Would be easy feature to add.
-- vurden, 2024-11-12

### ***** "Found my rattle"
Got this to find a rattle in my system. Found it at about 70 Hz. It was the TV base on top of my sound base. This will be an easy fix with some buffer material. Great app.
-- Cant pick, 2019-06-17

### ***** "Excellent"
I always keep this app hand when setting up a new system. No lag, no frills.
-- Dprill95, 2018-02-15

### ***** "Does what it suppose to do"
This app is easy to use and at a fair price I don’t have anything negative to say about this app just it not for boosting bass on music it’s for adjusting your amps and for setting the gains on your amps more correctly this way you can avoid clipping
-- Mr Magic 831, 2017-10-22

### ***** "Works"
No complaints. It works how its supposed to. Only buy this app if you have subs. Otherwise it wont be too useful
-- Dillon244, 2016-06-13

### ***** "The best subwoofer testing app... Period."
Evidently some reviewers on here are not taking 10 seconds to read the app description...  This app is **ONLY** for testing subwoofer systems in vehicles, etc.  And it does an amazing job of that. Has 12 different preset test frequencies, beginning at 20 Hz, the user can select with the press of a button...even has a slider so you can adjust the frequency down or up a little.  Perfect for testing and finding the weak spots in your subwoofer system, so you can adjust and improve your car audio system&#039;s bass performance.
-- Johnnierr, 2016-03-21

### ***** "This is an app to test with"
This doesn&#039;t add bass to songs. It&#039;s just here for people to test speakers and subs. What did you expect
-- Silly10101, 2015-08-10

### *---- "Crap"
See 1st review
-- MetalMan3, 2015-01-23

### *---- "Disappointed"
Perhaps I do not properly understand how to operate this APP?   I thought it was supposed to help add BASS to my music library?  The only thing that it did was create a buzzing noise as I increased the BASS on the APP.   Annoying and very disappointing, along with more $ down the drain.

Still in search of a good Equalizer APP to help me add BASS to my iTunes, music library, etc.

Any ideas?  Thank you in advance for you help.
-- #1*snowflake*, 2014-12-31

### ***** "Perfect"
This is just what I needed! I cant believe that I actually found an app that can do this! Definitely worth the money!
