Hard as Rock Yet Eloquent as Ivory

Speakers are extremely important when it comes to the recreation of high quality sound from CDs, MP3s, radio signals and more. MB Quart engineers built the all new Onyx series speakers from the ground up to be an affordable speaker with the audiophile and performance enthusiast in mind. This series is composed of value-packed 2-way and 3-way speakers that are constructed of the same superior technology in MB Quarts other lines. All Onyx Speakers come elegantly designed with a glossy black piano finish woofer cone and rubber surround. The stamped steel basket touts black high-gloss paint to accent the polypropylene woofer cone and contrasts well with the red progressive cotton spider. Matching these speakers perfectly the line of Onyx Amplifiers shows off the same piano black finish applied to their heatsinks and outer casing. No need to find a match maker, it’s already been made.

You won’t find a lack of features at this price point. Onyx series speakers come equipped with 30mm WideSphere titanium dome tweeter with matching piano gloss finish. The piano black polypropylene cone is suspended by a rubber surround that allows rapid movement to hit all notes. The crossover system has been designed to filter out unwanted frequencies and supply the tweeter and midrange with the power they desire. Tweeter attenuation on the crossover allows 0db, -3db and -6db steps so you can tune your system the way your ears want to hear it. Top it off with a black smoked crossover case to continue with the sophisticated theme and you have yourself Onyx series speakers.

Great speaker for the money. Definitely an entry level Quart but great sound reproduction non-the-less. I wasn't going for professional level audio just something better than stock. I have a ford pickup and WOW did these speakers wake up that factory deck. I'd say not only a clarity/detail improvement but a Volume level improvement aswell. The only thing they lack is bass but really its a 5x7 what do you expect. (Also I'd like to add the placement and size of cab are not lucrative to good bass. Oh and they are a million times better than the factory speakers.)
