The PSB Imagine X series is a characteristically masterful approach to budget speaker design from a brand with a great pedigree. The Imagine XB and XC would play reasonably loud with a budget receiver, but to get their full flavor, you’d need a higher-end receiver, and it would be worth the $1K-plus investment. The 8-inch SubSeries 125 is an excellent performer for its size and modest price, though the system would benefit from the greater weight of an equally well-designed but more substantial sub. So Imagine X could be the foundation of an excellent starter system—but it could also serve in a step-up system with a more powerful receiver and a brawnier subwoofer. Isn’t it nice to have options?
