I've been testing out inexpensive speaker equipment with my home made amplifiers for the last two years and with the addition of these subs, my system is now entirely goldwood speakers and subwoofers. Their HDS kevlar ceiling sub has never rattled apart, so I have two of those as well. They're the most reliable brand, with no frills design, high sensitivities, and to date, not a single burnt driver in my speaker graveyard. Goldwood reports and performs accurately to specifications. This model jives well with the TDA8954TH chip, but be aware that this amplifier chip is designed for 8-ohm impedance only when in BTL, which is the only configuration that delivers the desired 420W per channel to run this subwoofer. The chip is compatible with lower impedance in stereo mode which may be confusing if the board runs two chips in mono-BTL to create an overall stereo, 2 channel, amplifier board..
