Introduction to Paul Adams' Modified Prius
Paul Adams showcases his 2012 Toyota Prius V, which is nearing the end of its current project phase and is about to be swapped out. The car features a true infinite baffle (IB) setup with a massive 24-inch Stereo Integrity subwoofer. The audio system includes True Audio amplifiers configured with a mono block for the subwoofer and separate amps for the mid-range and tweeters.
Amplifier Configuration and Custom Modifications
The True Audio amplifiers are completely modified with Class A line drivers, including the subwoofer amp. These amps feature billet output cards, typically found in top-of-the-line models. The car uses a spare battery to power the audio system due to the challenges of running high-end audio equipment in a hybrid vehicle. The entire system, including the amps, processor, and computers, runs off this secondary battery, which is connected to the car's inverter.
Head Unit and Customization
The Prius does not have a traditional head unit; instead, it uses a Windows PC for audio control. The car features custom-made carpet and sound-directing elements. The system has evolved significantly, with previous iterations using different amplifiers. The current setup includes custom fabrication work to optimize sound quality.
Front Stage Setup: Speakers and Enclosures
The front stage includes SB Acoustics Satori mid-range drivers and Satori AMT (Air Motion Transformer) tweeters. The speaker angles are designed to create a point-source-like response. The mid-range drivers are housed in sealed enclosures built into the doors, utilizing the factory contours to maximize airspace. The enclosures take advantage of the space behind the window, including the defroster vent channel, to increase the effective volume for the 5-inch drivers.
Control System and Daily Use
The audio system is controlled via a tablet, which serves as a screen for the Windows PC mounted under the back seat. The rearview mirror has been replaced with a digital display connected to rear-facing cameras to eliminate reflections. The modified Prius is Paul's daily driver.
Future Plans for the Lexus
Paul discusses his plans to modify his Lexus, including changing the layout to incorporate separate sealed boxes for the Scan-Speak subwoofers in the back. He is considering adding dual 10-inch mid-bass drivers in the floors instead of the doors, while retaining the Dynaudio speakers.
Trends in Speaker Materials
The conversation shifts to new trends in speaker materials, particularly textream carbon fiber, which is used in the tweeters. Beryllium is becoming less common, with manufacturers like Scan-Speak using textream for their tweeter domes. Other companies, such as Orca (Raven line) and Natan Budiano (SB Acoustic), are also adopting new materials. SB Acoustic is launching a new line called SB Automotive, featuring speakers designed specifically for car audio.
Infinite Baffle (IB) Subwoofer Setup
Paul shares his experience with the infinite baffle (IB) subwoofer setup, noting the psychological hurdle of cutting a hole in the car. While it initially felt strange and increased road noise, the resulting sound quality made it worthwhile. People outside the car often struggle to locate the source of the sound due to the unconventional setup.
