Why Upgrade Dash Speakers?

Many drivers focus on:

• Door speakers
• Amplifiers
• Subwoofers

But forget that dash speakers play a major role in:

• Vocals
• Instrument detail
• Sound staging
• Overall clarity

When dash speakers fail, music often sounds:

• Distant
• Muffled
• Flat
• Unbalanced

Replacing them can dramatically improve the overall listening experience.

Sometimes more than upgrading larger speakers.

Featuring a 2-way design with separate drivers for different frequency ranges, they provide accurate, balanced sound reproduction. With a peak power handling of 60 watts and continuous handling of 15 watts, these small speakers deliver dynamic, clear, and precise audio at any volume.

Premium Pioneer A-Series Sound

The A-Series lineup is engineered to deliver:

• Smooth frequency response
• Detailed vocals
• Balanced sound reproduction
• Improved efficiency

Compared to aging factory speakers.

The result is:

• Better music detail
• Cleaner vocals
• More realistic sound

Without requiring a complete audio system overhaul.

Because not every audio upgrade needs to involve an amplifier rack.

Their broad frequency response of 60 Hz to 28 kHz ensures wealthy sound reproduction across numerous music genres. The enhanced sound clarity comes from a 25mm tweeter for crisp highs, paired with a 3.5″ carbon and graphite reinforced IMPP cone for reduced distortion and increased rigidity.

2-Way Speaker Design

The TS-A878 utilizes:

Woofer

Handles:

• Midrange frequencies
• Vocals
• Instrument fundamentals

Tweeter

Handles:

• High frequencies
• Treble detail
• Instrument separation

This separation creates:

• Better clarity
• Improved balance
• More accurate sound reproduction

Compared to traditional single-driver factory speakers.

Because asking one tiny speaker to do everything rarely ends well.

Smooth Treble Response

One of the standout features of the A-Series:

• Smooth high-frequency performance

Benefits include:

• Improved vocal detail
• Cleaner cymbals
• Better instrument separation
• Reduced listening fatigue

Without becoming overly bright or harsh.

Because nobody wants tweeters that sound personally offended by your playlist.

Designed for compatibility with more than a few vehicle systems, the TS-A878 speakers make a very good replacement for factory-installed speakers or a simple upgrade for existing setups. Professional installation is beneficial, though they are able to be installed DIY with proper vehicle and electrical knowledge.
