SB Acoustics Bromo 2-Way Speaker Kit - Pair
Overview
Bromo is taken from an active volcano in East Java, Indonesia. The name Bromo is derived from a word in Javanese: pronunciation of Brahma, The Hindu creator of God. It is a 2-way ported speaker with hard material drivers including the SB17CAC35-4 woofer. Ceramic provides a very hard and robust surface with improved sonic properties and cosmetic appearance. The SB26CDC-C000-4 tweeter combines the exceptional detail of a metal dome with the smoothness and non-fatiguing characteristic of ceramic. Experience superb high-frequency extension and authoritative mid-bass reproduction.
The drivers are known for very high performance, low distortion and unique price-performance ratio. The NBAC (aluminum) mid/woofers and CAC (ceramic) woofers can be both used with the same crossover designed for this kit. Tweeters ADC (aluminum) and CDC (ceramic) are also interchangeable. Though the specs are similar, both setups are audibly different. The ceramic set is subjective step up form a relatively small difference in price.
This is a hard cone/dome kit but without the typical ‘issues’ as audible breakups of the mid-woofer and the tweeter never get too harsh for the ears. The speaker is detailed and more ‘punchy’ than what was expected from this cabinet size, while displaying a noticable lack of coloration. A demo was done at Axpona Show 2019 & 2023 in Chicago and we received huge positive feedback.
SB Acoustics has developed, built, tested, listened, and are proud of this kits performance. All development details are available on the SB Acoustics website.
