Product Details

Peerless 830875 6-1/2" Nomex 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. The famous Peerless Nomex cone offers neutral, accurate audio reproduction.

Peerless 830875 6-1/2" Nomex Cone HDS Woofer
Peerless 830875 6-1/2" Nomex Cone HDS Woofer is rated 4.375 out of 5 by 8.
Rated 5 out of 5 by from AppealI cannot measure the output response, specificly the bass extension. All I can do, is use my ear, next to the Dayton 7" aluminum woofer, costing about 1/2. Comparatively...the Peerless driver has clear and detailed reproduction, and it seems, in the proper cabinet has very significant bass output, however, in my test cabinets, the projection is a bit deceiving; I have no qualm that a speaker designed with this driver can be a very serious contender in a commercial endeavor. I paired the Peerless nomex driver with a ribbon tweeter with a simple 6db 3.3uf crossover. The nomex woofer extends into the crossover frequency and the natural mechanical rolloff created a very good working crossover into the ribbon. I believe the parameters of this driver are "Remarkable". My 4.5 on the scale for 'features' was given only since there is no bucking magnet mounted, and in the current speaker market, basing a tower speaker on this driver requires keeping it away from CRT. Alternately, if the driver is high in the cabinet the weight toward the top of the cabinet is lower without a bucking magnet, and the stability of a cabinet with a small footprint is greater with a low center of gravity. 'Entropy' on my design sheets is a 3' tall 8.2 x 8.2" of such design, using the Vas of the driver with additional port full-length resonance 20hz. 'Entropy' uses a pile of scrap steel in the bottom, capped with resin to solidly couple the tower to the floor. The Peerless driver in my 5-way configuration coupled with a ribbon tweeter created a seriously large soundstage.

Rated 5 out of 5 by from Look at the spec sheet, what a nice FR!This is the woofer used in the "Elsinore" speaker (which I haven't heard, but I'd like to). It's well constructed, has a shorting ring, very open on the back side (NICE cast frame). If you went some other high $ woofer ($100 +) don't assume you'll end up with a better speaker. Cost is not always equal to sound quality. Low distortion, decent excursion and efficiency, moderate box size - all around great woofer.

Peerless 830875 6-1/2" Nomex Cone HDS Woofer

what is the port length in a .50 cabinet to tune to 45hz?

Asked by: single leg steve
Port length also depends on the area of the port opening.For this driver I would use at a minimum of a 2" diameter port to keep air velocity down.Here are some port lengths for round ports:1.5"D = 4.5"L2"D = 7"L2.5"D = 11.25"L3"D = 16.5"L
