## Description

Pioneer TS-B401PRO 4″ PRO Bullet Tweeter

Review: TS-B401PRO Pioneer 4" Tweeter - These tweeters are just nasty! Paired with a pair of D4S 65v2 and D4S JP84 amp. I still need to configure bridged to test the amplifier's performance. This chuchero box sounds wonderful and I'm still tuning on it. Pros: build quality, freq. response, rms capacity Cons: none for me I bet once it's bridged, it's going to stay that way. Including 2 10" DD Audio Redline 10" subs + DD Audio D1100 monoblock 1100w RMS amp. *** 10/23/2024 *** bridged the D4S JP84 amp @ 4Ohm 280w rms 2 channel and the 401Pro tweeters have fantastic performance. The D4S 65 v2 speakers have such a frequency response the tweeters are almost unnecessary. The audio system sound fabulous! It's like butter! *** 3/15/2025 *** Purchased a second JP84 amplifier to power these super tweeters. The JP84s consistently dyno at 300w RMS bridged @ 4Ohm so each tweeter will be receiving 150w RMS @ 4Ohm, as will each of the new 6.5" marine grade speaker upgrades (D4S HexiCone NEO HexiPRO cs65 6.5" carbon fiber speakers). Definitely increasing my -dBi!
Review: Lightening - I'm not saying because they are too good and I need more.
