Pioneer UD-RP401PRO Repair Kit - Replacement Diaphragm TS-B401PRO 4" P.R.O. Series Bullet Tweeter

My husband loved them for his truck, I recommend them, they have great sound

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!

Pioneer TS-B351PRO 3.5" Bullet-type 4 ohm tweeter (sold as pair), replaceable voice coil capability High-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.

No es and good

Imo... they better than the 4in. They sound cleaner n the highs are crisper. I love them

Muy buenas y bien equilibradas

There is a capacitor you have to Hook up when you connect your positive and negative wire leads. Had a system for a very long time then added these and now there's a pop when I turn on my vehicle that was not there before.

speakers sound good for size.
