Source: monoprice.com (verified 2026-07-11) · corroborated by ecoustics.com. Confirmed the exact model on three fetched pages: the dated ecoustics review (updated June 25, 2023) detailing the Monolith M-12 V2 (Product Number 42847, 12-inch), the Amazon Monoprice-Store listing (ASIN B09LSSG9LP, model 142847), and Newegg (model 142847, UPC 889028170403, first listed Feb 2, 2023) — none are the M-10 (42843) or M-15 (42851) siblings. The ecoustics review supplies the verbatim specs (Class D 500 W RMS amp, HDF dual-ported enclosure, -6 dB vented/Extended-EQ response 17-200 Hz, 25.8 x 16.7 x 22.8 in cabinet, 98.34 lb) and the US price "available for $849.99 at Monoprice.com," with Amazon/Newegg corroborating the 12-inch 500 W RMS identity and wired RCA/XLR (no wireless) inputs. The manufacturer product page (p_id=42847) returned HTTP 403 and could not be fetched, so all values are taken verbatim from the review; 900 W peak power (present on Amazon/Newegg but absent from the cited review) and driver orientation are left null rather than risk an unverified figure.
