Bundle contents and purpose

This package combines an 8-channel digital sound processor amplifier with two shallow 10-inch subwoofer enclosures and two 6.5-inch coaxial speakers. It is intended for vehicle owners who want a complete Hi-Res audio upgrade without assembling separate components. The all-in-one amplifier simplifies installation by integrating processing and power in a single chassis. Buyers needing more than eight channels or a different speaker format should look elsewhere.

Processor tuning and enclosure benefits

The PXE-C80-88 OPTIM8 provides real-time sound tuning via a PC or iPhone app, offering both manual and automatic modes with a 31-band parametric and graphic EQ. This allows precise correction for cabin acoustics and personal preference. The SS-SB10 enclosures use an ultra-shallow design measuring 18.5 by 4.5 by 12.5 units, fitting tight spaces while delivering 300W RMS power handling through Gen2 DD-Linear Magnetic Circuit technology. Adjustable foam-padded brackets give flexible mounting options.

Power handling and frequency headroom

The R2-S65 coaxial speakers are Hi-Res Audio certified with a frequency response up to 40kHz, using a glass fiber reinforced cone for clarity across high and low frequencies. Each speaker handles 100W RMS and 300W peak power, matching the subwoofer RMS rating for balanced system headroom. The 16.5 cm woofer diameter supports mid-bass reproduction alongside the dedicated subwoofers. Systems demanding higher continuous power or lower frequency extension than the shallow enclosures provide will require different hardware.

Questions about this item

How often will the 31-band EQ on the OPTIM8 processor need retuning?

The 31-band parametric and graphic EQ is adjusted via software; once calibrated it holds its settings unless you deliberately change them, so no periodic retuning is required.

What limits sustained output first — the 300 W RMS subwoofers or the 100 W RMS coaxial speakers?

The R2-S65 coaxial speakers are rated at 100 W RMS each, while the SS-SB10 subwoofers handle 300 W RMS, so the coaxial speakers reach their thermal limit first under continuous high-level playback.

How much heat does the 8-channel amplifier in the OPTIM8 produce during all-day use?

The built-in 8-channel amplifier is designed for continuous operation; its chassis dissipates heat passively, and no external cooling or duty-cycle restriction is mentioned for normal listening levels.
