Choosing a suitable mid-bass speaker is the core issue of low-cost high-fidelity speakers. Only by finding a low-priced but high-performance unit can we make a satisfactory speaker. We hope that the total cost of a pair of speakers will be controlled within 300 yuan, so the unit price of the bass unit must not exceed 50 yuan per unit; from the unit performance requirements, the size of the magnetic steel should be relatively large and the diameter of the voice coil should also reach 1.5 inches, otherwise the Q value will be too high or the power capacity will be insufficient. Of course, we can only choose domestic brands. After inspecting the relevant products of many domestic manufacturers, our ultimate goal is to lock in \"Tianlai\". We have used some products of Tianlai, from 5 to 10 inches including dome tweeters, and we are not very satisfied with their performance. However, after comparing many manufacturers, I feel that Tianlai still has the highest performance-price ratio.
