Product Details

Celestion Neodymium 5" Full-Range Woofer 4 Ohm

This 5" full range OEM driver from Celestion was designed in Great Britain for use in high-end, lightweight acoustic instrument speakers. A neodymium motor not only makes this speaker light, but it also reduces distortion by focusing all of magnetic power into the gap and onto the voice coil for complete control.

The neo motor also features a bumped backplate for reduced voice coil "bottoming out" conditions, while a paper cone is mated to a cloth accordion surround for a natural, warm midrange tone. This speaker is also nice to look at due to its rounded stamped-steel frame without requiring a recess in the baffle. 

Flat frequency response from 200 Hz to 6,000 Hz, and useful to 9,000 Hz, this driver is well suited for use in HiFi home audio systems, the reduced mounting depth is useful in car and mobile audio systems, and output is high enough (89 dB 1W/1m) for professional audio applications as a midrange in three-way systems or a full range column driver for line arrays. Available in 4 and 8 ohm versions to cover a wide array of applications, including building your own personal monitor speaker. Factory buyout with limited quantities!

Note: For even greater maximum power handling, a 330 µF capacitor for a 1st order crossover point of roughly 125 Hz is recommended.

Celestion Neodymium 5" Full-Range Woofer 4 Ohm
Celestion Neodymium 5" Full-Range Woofer 4 Ohm is rated 4.75 out of 5 by 12.
Rated 5 out of 5 by from Great speaker, great priceI bought these speakers roughly six months ago, along with some closeout 8 ohm tweeters and some crossover components - I noticed there's a huge peak in the 5k-10k area, so I crossed them over at 5k, using a 1st order highpass for the tweet, and a 2nd order for this celestion. I made some bookshelf speakers with them using some scrap 1/2" particle board and some foam leftover from a household furniture project. The box used roughly their recommended box size and tuning - I settled with roughly 329.5 cubic inches, and 89hz tuning or so, using some 1+1/8" PVC pipe (internal diameter) to make the port. The box ended up being 8" tall by 8" wide by 8 5/16" deep. I'm using them with a Lepai LP-2020A+ 20w/channel amp. With the relatively low volumes these bedroom/computer/bookshelf speakers were made for, this setup has plenty of bass, good treble, and nice, clear midrange. I don't really have the time or energy to draw up any plans, but I pretty-much explained everything that I did, aside from setting the baffle inside the cabinet by 1/4". In order to make the tweeters fit, I had to cut them down into a triangular shape. Anyways, I really like these, and they can get pretty loud - the only thing is that the bass on them doesn't carry when they go loud, but that's perfectly fine by me. Part of me wants to get another few pairs so I can do the exact same thing for work, and for the garage!

Rated 5 out of 5 by from little gems!very detailed in the midrange...excellent imaging...using in a line array....tested in a small closed 9x6x7 enclosure with Dayton domed tweeter...crossed a 5000k......believe these little gems are a steal.....does not produce much in the mid bass range but not why I purchased them...bought 48 for three line arrays for my kids as a graduation present for getting their degrees from college...hurry before they are gone forever

Rated 5 out of 5 by from Great for mediums.I bought this to replace my old fender passport speakers.Great improvement, very clear, and only costed me 9,99 each.I will need something else for the bass, this do pritty well with the right enclousure and some eq for acoustic music.

Rated 4 out of 5 by from Good replacement for a Cerwin Vega midrangeI bought this speaker a couple of months ago, to help a friend who blew the midrange on his Cerwin Vega VE15Fs. The fit was good, and it sounds great.

Rated 5 out of 5 by from Good stuff!This is the first time I toyed around with building a set of components for a vehicle, in this case my '85 F-250 where these are used as door speakers, with a Vifa textile dome 1" tweeter.I tried a couple different crossover configurations, first was high pass 2nd order butterworth on the tweeter at 4100hz, with first order low pass on this 5" driver also at 4100. I thought I didn't like it, and tried a 3100hz crossover with 2nd order LW filter on both.. Turned out the first one seemed to have a better frequency split between the two, the tweeter didn't sound as strained at higher volumes. Tweeter was wired reverse polarity in both configurations.After settling at the 4100hz crossover and installing them in the vehicle, these things came to life. It's interesting to note that this driver when wired as full range has quite a wide frequency response. It could almost be used entirely as a full range driver, except for the highest audible frequencies, where you'd need a tweeter. The highs sounded so good with hardly any straining or breakup, I almost hated putting the LPF on, but the tweeter takes over nicely where the 5" leaves off.I have these on a 4 channel Aura 50 Wrms/channel amplifier (two tens on the third & fourth channel take care of the lows) and these seem to take all the power I care to throw at them. They will crank up to a deafening volume before starting to distort. Seem to have decent excursion and low end for a driver this size, though a subwoofer is needed to get any usable volume at the lowest frequencies.The clarity and accuracy of these is second to none, and they matched my tweeter well despite practically pairing two random drivers (cost was my primary consideration) and attempting to make them place nice with one another. They do have a noticeable emphasis on the midrange, but this was easily offset with the EQ on my head unit. Excellent build quality, I have no doubts that this is a speaker that will last.

Rated 5 out of 5 by from Used the 8ohm version so far.Purchased 4 of these and 4 of the 8ohm version. I replaced the single 5.25" midbass driver in a pair of Sonance mariner 100 speakers with these 8ohm.Fit perfectly and I couldn't be happier look better too.Im listening to them right now with a 10" sub w/eminence BP102.The factory speaker should go in the trash compared to this one,it "factory" driver may have played a hair lower?I also used the other pair of 8ohm 5"celestions in a 3way from 750-3000hz and they are as good or better than the 4-5in drivers I have used from TB and Dayton at 4x the price.Now I need something to make with these 4ohm.Buy em cause one morning your gonna check the speaker buyouts page and they will be gone like the 6" Auras and the 6.5" focals both of which I have a few of and will buy a few more of these in 8ohm version,Enjoy.

What would be the Sensitivity of using two of these in parallel? If I understand correctly it would be around 90 db since the stated sensibility is in w/m instead of 2.83v/m. Am i correct?
Asked by: Moose87
You gain 3dB for every doubling of the number of speaker drivers.In this case you would also gain an additional 3dB of sensitivity because you are having the impedance by using two of the speaker drivers in parallel. This enables more power to flow through the system (assuming your amplifier can keep up without overheating) the speakers themselves stay the same, the system just puts out more power enabling more gain.To recap:You get +3dB greater sensitivity from doubling the number of speakers.And you gain and additional +3dB from the doubling of current flowing to your speakers.Hope this helps.

Would this be suitable in infinite baffle use, as in open back guitar amp or pa speakers?

Asked by: Whitewinddesigns
Yes this will be suitable for an OB application.

Looking at the spec sheet it seems that the magnet gap is only 1.375 mm deeper than the centered coil. Given that the x-max rating is 1.25mm that doesn't leave much "buffer". Is there a "real" x-mech parameter for these things? [PE doesn't do destructive testing do they?]
Asked by: chmedly
I am sorry, we leave all destructive testing to the manufacturers.

Has anybody modeled boxes?

Vented? Closed? How about an array of 5 in a single box?
Asked by: namenick
I would recommend vented only for this driver unless you do not want anything below about 250 Hz, in which case the sealed size makes no difference. The vented volume is .25 cubic feet with a 1.5" diameter, 1.5" long port for a tuning frequency of 89 Hz. If you want to use 5, just multiply volume and port quantity by 5.

Zobel suggestion?

Thanks in advance for any Zobel impedance compensation suggestions. Found something that worked? Trying to cross 1st order around 6000Hz so the car tweeter can take over from there. Can't read the impedance curve properly...
Asked by:
I would recommend a 3.3 ohm resistor and 10 uF cap for a zobel at that crossover frequency.
