Peerless SDS-160F25PR01-08 6-1/2" Paper Cone Woofer Speaker
Peerless SDS-160F25PR01-08 6-1/2" Paper Cone Woofer Speaker is rated 4.6 out of 5 by 5.
Rated 4 out of 5 by from Great for the price.I bought these not expecting great things considering the price.I have had some problems regarding the chassis, one had a very buckled chassis and the replacement also had a slight buckle that wasn't bad enough to stop me fitting/using it. Although it does have a resonance around 300hz.Overall I'm pleased with the results in my experimental transmission line speakers.These are used with Morel MDT32S tweeters with crossover at 2.1khz .I will most likely replace them with something more of a match for the Morels at some point.Parts Express were very quick to replace the faulty unit and it is this after sales care that will retain my custom.

Rated 4 out of 5 by from excellent driver!a 6.5 driver with a characther that doesn't strike your attention while reproducing, very ''laid back'' sounding, very flat response, it can go low on a proper box, and is easy to work with. a bit unefficient but it makes up with dynamics. only poblem is power handling, maybe due to low frequency over-excursion, i haven't fed it with 60w but i have been able to get some distortion at relative high volumes on drums/kicks, but overall very clean sounding. that paper cone is great! recomended crossover point 1.5k-2k with 12db slope.

Rated 5 out of 5 by from Makes me smile!One of the best drivers I've had the pleasure of using. Haven't measured low end extension but put up against a wall it has "sufficient" low end that I don't need to turn on the subwoofer for music primarily consisting of >45 Hz. I predict with a solid 6 dB boost from 40-60 Hz that this speaker would be flat down to 43 (what I tuned the enclosure to, +-3 Hz). I'm not going to point at any company in particular but I believe that this woofer (or a clone) is used in a new studio monitor line that I saw at NAMM. Excellent woofer with or without considering cost. I have it low-passed at 2800 with a 3rd order butterworth and the beaming isn't too noticeable (see charts). For the record they are getting about 0.6-0.65 cu.ft internal (each) and they sound solid even though bassbox would like a larger enclosure for a lower tuning. However, one thing is that the smaller enclosure does help limit over-excursion and my design doesn't exceed 6.5 mm until 60 W RMS below 34 Hz.

Rated 5 out of 5 by from Great midbass speaker.I used 8 of these speakers in a 2-way MTMMM set-up (4 in each speaker) The project turned out really well, but if I were to do it again I might have designed the speaker for "High Fidelity" instead of "Extended Bass." They reproduce percussion really well, but they also produce a lot more bass than I had anticipated. Anyway, for the price ($18) you can't go wrong.

Peerless SDS-160F25PR01-08 6-1/2" Paper Cone Woofer Speaker

Hi, Ordered two of these for experimenting with transmission lines and maybe then back to sealed/ported if that doesn't work out. Will these work OK with Morel MDT32S tweeters? Was thinking of XO at approx 2.5kHz.

Asked by: Jonion
Yes these will work well with that tweeter and crossover point.

What do you think of running this speaker with no crossover. Using in a small video system. Would like your input. Thank you.

Asked by: ron9632
If this is used full range with no help from a tweeter, it will have very limited output above about 2 kHz unless you are listening to it directly on axis. Even then it will only play to about 4-5 kHz, so a tweeter is recommended. Running this with no crossover will not damage anything however.

What is the "horizontal" overall width of this speaker compared to the "vertical" width, since the sides are sliced off?

Asked by: Marvin 100
The frame of this woofer measures 6.45" across the flats and 7.165" across the round edges.

I am going to build a 3 way floorstanding speaker with double Dayton Classic 8" woofer as bass drivers, and a planar tweeter. Is it a good choice as a mid range driver for the frequencies around 800hz-8khz. Is it covering 35hz - 20khz as written? 

Asked by: markpen883
The stated frequency response is a bit ambitious and based on the response graphs in the spec sheet, it is not accurate. I will have this updated online. The highest I would cross this driver is about 2.5kHz.

What size enclosure for 2 of these? vented or ported. If ported what size port.

Asked by: okiefz1
A sealed box volume would be .7 cubic feet for both woofers, this will provide an F3 of 80 Hz. Vented is quite a bit larger at 3.2 cubic feet with a 3" diameter port that is 2.5" long. This provides a tuning frequency of 33 Hz.

the details say a 20000 upper limit, what is the real number??

PRODUCT SPECIFICATIONSPower Handling (RMS) 60 WattsPower Handling (max) 120 WattsImpedance 8 ohmsFrequency Response 35 to 20,000 HzSensitivity 87 dB 2.83V/1mVoice Coil Diameter 1"
Asked by: Mawdeeb
If you look at the frequency response in the specification PDF it starts to rolloff above 5 kHz on axis. However I would go no higher then 2.5 – 3 kHz with it as it starts to beam around that point and you want to cross below the cone breakup at 4.5k.
