Short answer: the Pitt & Giblin Superwax Mini. It ranks #5 of 8 powered floorstanding speakers by sound quality, rated 4.6/5, at $15,175; the Grimm Audio LS1c + SB1 ranks #7, rated 4.4/5, and costs $28,850, which makes this an easy call rather than a real tradeoff.
The case for the Pitt & Giblin Superwax Mini: The published DSP-adjusted manufacturer measurement shows a 1.2dB response span from 300Hz to 5kHz and a 8.60 ideal-subwoofer preference score, supporting natural vocal balance. The tradeoff: The Mini gives up some deep-bass reach compared with the full Superwax.
The case for the Grimm Audio LS1c + SB1: Independently measured by Audio Science Review as a complete system with its SB1 subwoofers, with 0.83 listening-window smoothness and 0.38dB average on-axis deviation. Watch for: The standard preference score is only 5.73, rising to 7.54 with an ideal subwoofer, because spinorama puts the system’s -6dB point at 45.4Hz despite the subwoofers.
Buy the Pitt & Giblin Superwax Mini. It is rated higher for sound quality than the Grimm Audio LS1c + SB1 and costs less, which makes it the one to get unless you need something the other one does better.

The Two Speakers In Full
Pitt & Giblin Superwax Mini: $9,800 per pair Pitt & Giblin eBay
Pros: The published DSP-adjusted manufacturer measurement shows a 1.2dB response span from 300Hz to 5kHz and a 8.60 ideal-subwoofer preference score, supporting natural vocal balance. Bass reaches 30.9Hz at -3dB. The 15-inch woofer, bronze waveguide and built-in amplification provide a substantial two-way system with both digital and analog connections.
Cons: The Mini gives up some deep-bass reach compared with the full Superwax. Its low cabinet height makes the supplied tilt feet and listening position important. At 40kg per speaker and 460mm wide, it is still a large installation. The quoted response describes the measured DSP tuning; alternate voicing profiles change the balance.

Grimm Audio LS1c + SB1: $43,440 per pair The Listening Room eBay
Pros: Independently measured by Audio Science Review as a complete system with its SB1 subwoofers, with 0.83 listening-window smoothness and 0.38dB average on-axis deviation. ASR found the widest horizontal dispersion it had measured, very clean decay and distortion that stays low at 86 and 96dB. The -10dB point sits near 28.9Hz, and the SB1’s motional feedback controls the 10-inch woofer. It is a complete active system with Hypex NCore amplification, DSP crossovers and analog, AES/EBU and USB inputs. Measured bass extension of 28.9Hz (-10dB).
Cons: The standard preference score is only 5.73, rising to 7.54 with an ideal subwoofer, because spinorama puts the system’s -6dB point at 45.4Hz despite the subwoofers. At $28850 per pair with the SB1s, it costs far more than active systems that score higher. ASR measured a maximum of about 105dB, modest output for the price. Custom finishes add weeks to the dealer lead time.
