super compact

(tagalog) : napaga ganda ng design perfect for small space, i did not yet tested since but my first impression are totally amazing for me, will install to my HYUNDAI KONA in the philippines thanks for the great deal! i will upload my video in my you tube channel

Powerful and convenient

This DSP has all the features you would expect from a DSP but its so convenient with the ability to control and monitor everything from your phone. My favorite features are the voltmeter, limiter and gain controls at your fingertips. It's also cool to be able to see the actual cutoffs of the crossover on the screen.

It’s ok

Hooked up and got it working does what it says but the blue tooth part sucks every time u want to change something u have to pair it back to the phone some setting stay and some change so I am going back to the old school EQ

A++++ products love them. This TPT-SP4BT have it all you are looking for can't ask for more.

Solid DSP

Let’s start by saying, the Timpano DSP is an excellent choice for newbies. For the price, the DSP has enough features to dial into your system. Bluetooth feature is a plus. Plus, the DSP is small enough to fit in tight spots in your vehicle. I would definitely recommend it.
