What the L-Acoustics SYVA-low+top does well: Vendor Spinorama data gives preference scores of 6.05 standalone and 8.11 with an ideal subwoofer, the best in this ranking. The tradeoff: A passive system that needs L-Acoustics amplified controllers (LA4X, LA12X or LA8).
The case for the Kling Freitag PIA M: High-quality manufacturer measurements give preference scores of 4.50 standalone and 7.92 with an ideal subwoofer, with a 1.7dB reference band and 0.82 predicted in-room smoothness. The tradeoff: Bass is limited, at 95Hz for -3dB and about 82Hz for -10dB in bass-reflex mode, so it needs a subwoofer for music.

The Two Speakers In Full
L-Acoustics SYVA-low+top Passive eBay
Pros: Vendor Spinorama data gives preference scores of 6.05 standalone and 8.11 with an ideal subwoofer, the best in this ranking. Pairing the SYVA line source with SYVA Low adds two 12-inch drivers, extending bass to about 50Hz (-3dB) and 137dB peak SPL. Listening-window narrow-band deviation is 0.188, and the 140° horizontal pattern covers wide rooms from one slim column. Measured bass extension of 50Hz (-3dB).
Cons: A passive system that needs L-Acoustics amplified controllers (LA4X, LA12X or LA8). The two-element stack is 2.15m tall and about 50kg, so it is an installed or touring system rather than a grab-and-go box. Vertical coverage is only about 25°, which suits seated audiences but limits use on steep or multi-tier rooms.

Kling Freitag PIA M Passive eBay
Pros: High-quality manufacturer measurements give preference scores of 4.50 standalone and 7.92 with an ideal subwoofer, with a 1.7dB reference band and 0.82 predicted in-room smoothness. The 3-way column has an adjustable tweeter array (5°, 15° or 25° vertical), a cardioid midrange and a woofer section switchable between bass reflex and cardioid to cut sound behind the speaker. It reaches 132dB from a slim 12.2kg cabinet. Measured bass extension of 95Hz (-3dB).
Cons: Bass is limited, at 95Hz for -3dB and about 82Hz for -10dB in bass-reflex mode, so it needs a subwoofer for music. It is passive and meant for Kling & Freitag amplifiers, and it is sold only through pro dealers with no published price.
