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 An Outstanding Woofer For This Price RangeI was truly impressed with the performance of this woofer. As others have stated you are immersed in the sound field of this quality woofer. Nice detail and great bass, but not over powering. A 2300 to 2500 x-over point with a 2nd order on this woofer seems to work the best. I tried a 3rd order and it made it sound abit lean and bass somewhat subdued as well. I installed a 3 dB L-pad on the Vifa tweeter to compensate for the woofers lower sensitivity. Overall a pretty impressive 2 Way speaker system. A .5 ported cab is a good choice for this woofer

Rated 1 out of 5 by from Not same as older unitsBE forewarned this is not the same 830875 as the older(say 2-3 yrs ago) units.. I have both used in exact same application..reviewing my old spec sheets.. the older unit have highter Qts and inductance.. hence more or bigger wire in voice coil./I have burned up and the VC unwound on two newer units with 60-65WRMS and wrecked my RS52 mids in the processIn the same app my older units routinely would take 150WRmswith no problem. still have them in use.. these blew in a WWMT wired up with the older units on same crossoverDEFINITELY A QUALITY or reliability issue here.

Rated 5 out of 5 by from Great in every aspectOne of the few 6.5" woofers with a clear, extended midrange and no real cone break-up. Excellent bass - larger than normal cone area and long xmax. Easy to work with, a LR4 slope can be obtained with a simple 2nd or even 1st order xover. Very good efficiency for a long-throw midwoofer. Works well in the Dayton 0.5cuft cabinet with a 2" vent tuned to 45Hz. Certainly one of the best all around woofers in this price range.*The woofer looks grey in the photo but it's actually black.

Rated 5 out of 5 by from Very pleased with these drivers.I recently purchased a pair of these 6.5 inch woofers to use with the Dayton DC28F-8 tweeters in a studio monitor build. Each one was put in a ported 18L cabinet tuned to 44hz. After about 6 hours of listening to various material, it is apparent that the midrange is quite excellent; when coupled with my tweeters, the drivers present a soundstage which immerses you very convincingly. They can play quite loud and appear to use their full xmax before any distortion is audible. The bass peaks at 55hz drops after 50hz and extends down to 40 hz before giving up the fight. This was in a 12 by 8 by 8 foot bedroom on a desk against the wall. The audible response of the woofers in these boxes is a flat midrange with a slight downslope from 200hz and down. (in room perceived response with sine wave test tones)

Rated 4 out of 5 by from great for car audio!after some careful consideration, I chose these over many other 'car audio specific' component sets costing upwards of $600.. i had hoped that the doors of my '01 eclipse would not be too much airspace..so far, they have played excelent. upon first installing them, i ran them without a lp x-over with no issues-- they cleanly played down to around 25-30hz, even at loud volumes! they have been in the car for almost 3 mo. now, using a 50hz 12db/oct lp, and 2khz hp with no issues at all.

Rated 5 out of 5 by from Supurb sound in a studio environmentOne of my biggest problems in the recording studio is ear fatigue. I have had so many monitors including the highly regarded Dynaudio bm15a's. I decided on these Peerless with the nomex cone after looking at the incredible frequecy response, and they fit my enclosure perfectly. I had built some very nice .46 cubic ft enclosures. The other drivers didn't fair well, but woke up in a larger box. I am so impressed with these peerless drivers. I crossed them over at 4500hz and get true flat response all the way down to 30hz with only a slight 3db roll down to 20hz! And they sound so very nice. I hear incredible amounts of detail. They throw a nice soundstage with lot of air. They sound so smooth in the midrange, and they really hold up with the bass. Finally an accurate monitor that sounds pleasant when the recording is good, and let's you know when the recording needs help. They took alright to my tube equipment, but really woke up with a 100 watt Rotel amp. The amp makes a huge difference with these drivers.

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

Is this a good replacement for the woofer in a Sonus Faber center solo?

Looking to replace a blown woofer on a Sonus Faber center solo. The dimensions seem to be a perfect fit. I have no idea on the TS params on the SF woofer unfortunately :-(
Asked by: kuvempu
I believe Sonus Faber outsourced to Peerless or Tymphany for the drivers they used so the physical fit should be perfect. There may be a slight difference in sound but as long as the impedance matches the original I see no reason it wont work.

X-Over Question

What is a good x-over point and is a 2nd order or 3rd order slope the best for a 2-way!
Asked by: jasm
i have this crossed around 2.3k 2nd order electrical with vifa xt25 and get almost perfect frequency and phase in a small 2 way around .5 cubes ported, with no eq applied at all, very easy to integrate and fairly cheap.

Is this the same part as 299-127? It seems to have the same model number 830875

Asked by: buyer
It does look so, and the T/S specs also seem to line up.

How low can you go?

If size was not a concern, what would be the ideal box and vent dimensions to really make the most of the low end for this driver?
Asked by: Nanuk
The largest I would recommend putting this driver in is a .8 cu ft enclosure tuned to 47 hz, a 3" diameter by 8.5" long port should get you there with minimal port noise or compression, this will give you an f3 of 43 hz.A larger enclosure and you start to get a peak in the bass, a lower tune and the low end will start rolling off early.

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
