Pioneer P.R.O. Series TS-B401PRO 4” Speakers (Pair) – 500W Max, Perfect for high-SPL Builds and pro-Level car Audio, Bullet Style Tweeter

Awesome little speakers.

Pioneer TS-B351PRO 3.5" Bullet-type4 ohm tweeter (sold as pair), replaceable voice coil capabilityHigh-quality alluminum construction and great sound. I had been eyeing these up for a upcoming project (custom-built concert-type speakers) for my backyard entertainment area. Ended up purchasing 2 pair of them during Amazon shopping days for a really good price. These are an improvement over the last model (TS-B350PRO), as they made the new TS- B351PRO with a replaceable voice coil for people who like to push the power limits of these tweeters.I plan on purchasing other P.R.O. series 4" tweeters, 6.5" mids, 8" woofers, and 12" subs for the rest of the project. I exclusively use Pioneer for all my audio. Please keep in mind, the P.R.O. series speakers were designed with more of an emphasis on power & SPL over sound quality. Don't get me wrong, the sound quality is very good though. It will do fine for this project.For my vehicles however, I prefer the route of sound quality over SPL, so I use their Z & PRS series components.

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 capacityCons: none for meI 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!

Sonido niiiitido, trabajan muy bien

Calidad de audio increíble

These should have come with wires already attached to the diode. Very difficult to hook up however the big deal is the sound. cuts out at 10000 and the sound is not crisp and clear like a tweeter should be. I was not even pushing 100 watts through them. I have a pioneer 7000NEX head and love all their products but these do not meet up to their quality.

Muy buenos suenas duro y nitidos

Exactly what you need to finish your sound
