  • Great build and sound quality at a reasonable price
Style: Tweeter (Pair) Size: TS-B351PRO
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. ... show more

  • TS-B401PRO Pioneer 4" Tweeter
Style: Tweeter (Single) Size: TS-B401PRO
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 300w 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! ... show more

They don't give you any speaker wire, have never purchased speakers with no wiring to connect to radio would rate this a zero if I could. Paid good money for these and thought I was buying a quality named product

  • Doesn't give upper most frequency.
Style: Tweeter (Pair) Size: TS-B351PRO
A good product but doesn't give the real high band very well. I would invest more in tweeters to get the best sound.
