The Pioneer Way
Writer: PICHET WONGNAK
It’s few and far between for this writer to get his hands - ears rather - on an audio system with championship credentials in the less-than-B60,000 category of the USAC Thailand competition. I was privy to this particular audio system fitted to a Honda Civic, costing B42,000.
Pioneer head unit replaces the factory-issue unit.
Components
The system comprised of the following components:
- Pioneer P80RSII head unit.
- Performance Colorful4000 power amps (two units).
- Two-way component speaker DLS PS6A, JL Audio 10W0 10-inch subwoofer.
Installation
This one, a winner, used a front stage setup style. The new Pioneer head unit replaced the factory-issue unit. Speakers were DLS P6A. And since they were component speakers, the tweeters went to the newly-built A-pillars for optimal angles .
The woofer was slotted in its original position, but the pros tweaked the woofer’s angle upwards for better sound stage.
Doors were treated with a bit of damping, five layers to be precise, which in turn enables it to work as a high-quality speaker enclosure that is capable of reducing exterior noise as well.
The wiring is tri-amp with an electric crossover integrated into the head unit without using a passive that came with the speaker set. The reason for this is to ensure convenient fine-tuning from the head unit itself.
The tweeter has a mid-range frequency filter for protection against the lack of a passive crossover.
Front speakers use a Performance Colorful 4000 four-channel to independently drive the two-way component one speaker/one channel setup.
Then the subwoofer JL10W0 installed at the rear as a closed enclosure uses the other Performance Colorful 4000 power amp to serve as a bridge mono to drive the subwoofer.
User-friendliness
Easy is the key word here. However, don’t meddle with the crossover because the sound quality will change.
You should remember the set parameters of this system or else you’ll lose hours trying to figure it out later.
Sound quality
After hours of listening, it was such a pleasant experience. The sound stage, image and focus were easy on the ear because of natural tonal balance.
If this system was subjected to a blind test (without seeing the actual system), the quality of sound would seem as if it was coming from a system worth hundreds of thousands of baht.
In reality, this Q Consumer 60000 champion spent only B42,000 on the head unit, speakers, power amp, wiring and damping.
In summary, this is the best system under B50,000 (including installation costs).
