BRS40 50 Watt, 4 Inch, Full Range, Replacement Car Speaker - Sold Individually

Very good base for a cheap speaker very much recommend as good as a good set of speakers

車に備え付けのダッシュボードスピーカーの音ががっかりだったので 同サイズのこのスピーカーが意外に格安だったので購入 低音は満足のいく音でした。高音もう少し出てくれると更に良かったのですが 良く見なかった自分が悪かったのですがペア（２個）価格かと思って購入したら １個でした。（慌てて追加購入しました(^_^;)）

For the price, which is simply incredible, these are 5-star speakers. I picked up 2 for a home stereo project (bookshelf mini-speakers). They arrived incredibly fast and were clam-shelled for extra protection. See picture below for contents. Speaker is 4" square. The leads are marked, but it is really faint; I used a flashlight to read the polarities. Speakers were tested on a Pioneer amp. At 25 watts (4 Ohm impedance) they were clear, loud, and without distortion. The bass registers but is nothing to write home about. The woofer does pick-up beautiful midranges clearly and with an audiophile level not expected for the price. It is a dual cone, so the tweeter is is a whizzer that really can't pick up the high range treble and is mediocre, but passable. The next test was at 50W - likely overdriven somewhat (~55W). Sound output was very good; loud, mostly clear and unexpectedly crisp on midrange (with limited bass) - it played a house mix with boom. Again, the treble suffered; it started to distort on treble laden rock songs (despite the amp actively filtering the signal). Despite this distortion, the speakers are surprisingly good, better than expected, and at that price... need I say more?

Clearly these are not intended to be audiophile quality speakers. But they seem well constructed and work well for my application, as OEM-replacement rear fill speakers. I'm using them behind the seats in my BMW Z3 -- even though they are full-range, they're being driven only in a mid-range capacity by the OEM H-K amp. I'm pleased.

Muito bom, veio bem embalado e sem avarias. Já instalei, ele vem com uma moldura para auxiliar a instalação.

Quedaron perfectas en mi jeep Comanche,buen sonido
