Product Details

Peerless 830870 4" PPB Cone HDS Woofer

The Peerless High Definition Sound (HDS) Series offers high-quality solutions for multi-way speaker systems employing vented box alignments. A powerful ferrite magnet system is coupled to a finite element analysis-designed suspension system, containing a linear spider design and rubber surround. The motor incorporates an aluminum shorting ring that reduces coil inductance, extending frequency response performance and reducing second harmonic distortion. A cast aluminum basket provides high structural rigidity, heat-sinking capacity for the motor, and additional ventilation under the spider that in combination with a vented cone neck reduces air compression effects. Peerless developed the proprietary and highly advanced Polypropylene Black (PPB) cone material used in the HDS PPB Series, creating a stiff but still dampened cone that remains stable even under the greatest sound pressures. .

Peerless 830870 4" PPB Cone HDS Woofer
Peerless 830870 4" PPB Cone HDS Woofer is rated 5.0 out of 5 by 1.
Rated 5 out of 5 by from Used in upgrading a vintage Passive Sattelite/Subwoofer systemI used this and other components in an upgrade for my vintage 1980’s Passive TMM Satellite/Subwoofer system. I wanted to keep the elegant cabinets and use them with my new receiver, so some of my selections were influenced by size and cut outs. But they all worked great together!First I replaced the old paper tweeters with Tang Band 28-847SD Shielded Neodymium Dome Tweeters (264-822) and it just woke everything up! Good detail. I then added the PEERLESS 830870 4" PPB CONE HDS WOOFERs (264-1070) combined with the Dayton Audio XO2W-3K 2-Way Speaker Crossover 3,000 Hz (260-144) and that produced a very rich sound.Lastly, I replaced the original 150 Hz crossover from subwoofer with a higher quality 100 Hz High Pass 4 Ohm Crossover (266-460), - The Peerless has more performance in the lower range on paper and perceived, and that let the midwoofers/tweeters produce more detail.Thanks to Parts Express tech folk for their help on this project.
