SB Acoustics Bromo 2 Way Bookshelf Speaker Kit - Pair

SB Acoustics

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.

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 a step up as you get more from the sound quality.

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 development done by SB Acoustics utilized the evenly distributed vibrations through 18mm MDF panels with bracing, lowering sound coloration. The speaker is detailed and more ‘punchy’ than what was expected from this cabinet size. A demo was done at Axpona Show 2019 in Chicago and we received huge positive feedback.
