Product Details

Celestion Neodymium 5" Full-Range Woofer 8 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, limited quantities! Factory buyout with limited quantities!

Note: For even greater maximum power handling, a 150 µF capacitor for a 1st order crossover point of roughly 125 Hz is recommended.

Rated 2 out of 5 by from Missing something?I have been watching these for a long time & finally ordered a pair of the 8 ohm version. I built some cabinets ~0.23cuft. They sound like a midrange speaker only, with some highs. Not FULL range at all. Pretty disappointing. No lows whatsoever. Even voices sound thin. I supposed they would be good as a mid range that many others are using it for.They will be going back.

Rated 5 out of 5 by from Upgraded midrange for 45 year old ADC18'sAs an avid audiophile and electrical engineer, the buyout price on these celestion full range drivers had me questioning the quality of manufacturing of this driver from ROC. Ordered 2, redesigned the crossover and could not believe how well these midranges performed after all the prep work. As a midrange, the price vs quality and performance cannot be beat! Thanks for offering PE!

Rated 5 out of 5 by from Awesome as midrange!I built a pair of 3-way towers and used these neos' as the midrange. As previously stated they do need break in time, but wow are they crisp. At under $13 they are a huge bargain!

Rated 3 out of 5 by from They're OK - great design and buildFirst, the magnet on these is serious - it's a large ring of rare-earth / neodymium so keep your pacemaker away! Also, the general build quality of the baskets, cones, etc is way beyond my expectation for such a low-priced driver.How we got "Full-Range" from a speaker that rolls off at 8000, I have no idea.I bought these for a small computer-speaker project and admittedly made the decision on price - at the buyout price on PE, it's pretty hard to argue. The surrounds are quite stiff out of the box and will require significant, high-volume break-in time to achieve good results. After some play-time, the sales description nailed it - guitars, for whatever reason - sound extremely natural. Voices, meh...not bad not good. They're just goof-off speakers anyway.Matched them up in a no-crossover piezo set of triangular-framed boxes, sealed enclosure. The entire project soup to nuts #including wood, poly, screws, everything# was $50. Built in about three hours #not including dry time, of course#, and at the price and effort I guess I really couldn't do better. They look pretty good, but response is $50 worth of colorless. Make no mistake, for the price there is little #or nothing# better out there so I'm happy. GREAT DEAL.

Rated 5 out of 5 by from High Value DriverThis driver offered a number of surprises. Reviewing the factory specs, these drivers look very similar to a number of Tangband fullrange drivers. I've been looking for a high-value driver for an MLTL project for some time, and this 5" Celestion fit the bill - the price is certainly right.Upon measuring the T/S parameters using the Dayton DATS system, I measured the following values (average of four drivers):fs=131HzRe=6.45 OhmLe=0.68 mH@1kHzBL=4.72 NAVas=2.86 LQe=1.024Qm=2.05Qt=0.68SPL=89.9dB/W/mThese values are quite different from the published specs. At first I had concerns due to the much higher fs, as the rule of thumb is that the lowest achievable f3 = fs/(sqrt(2)) - i.e. with fs = 131Hz, best f3 would be 93Hz. To my surprise, running the measured data through MJK's Mathcad worksheet, an MLTL with f3=65Hz is achievable. My modeled response is a bit rough still, but looks promising. If this holds true, this is good news as the driver can hold it's down into solid sub-woofer territory.The published SPL seems accurate, which is good news for use with smaller tube amplifiers, as I'm planning on doing.The top end is also surprising. In listening tests there isn't any offending breakup that I can notice, somewhat contrary to the graph on the spec sheet. Also, the upper frequency roll-off appears better than published graph would indicate. I don't have the ability to measure this, but used for background music you may not need a tweeter. For a high-end system you definitely do need it. If nothing else, to fight the beaming...The beaming is noticeable, borderline annoying. This shouldn't come as a great surprice for a 5" driver. 30 degrees off center and the top-end is way down. This would be the most compelling reason to add a tweeter.This exercise also proved to me the importance of designing enclosures off measured values as opposed to factory specs. Get the Dayton DATS if you haven't already, or learn how to measure T/S parameters the old fashion way.Over all a great value.

Will these work being wired parallel for simple home audio?

I have 2 cabinets for home audio. I'd like to put two of these wired in parallel in each one. Do I need to worry much about cabinet size or porting?I don't plan on using a crossover with them. Thanks
Asked by: MJ is new
These are essentially mid-range--great midrange, but just mid-range--speakers. With an Fs of 104hz, you're not going to get any bass out of them.Let us know the internal size of your boxes and what kind of music you like. We'll try to help you pick something to use with these for superlative listening without breaking the bank.Hope this helps.

Would this speaker have low harmonic distortion suitable for hi-fi use? My understanding is that musical instrument speakers sometimes add distortion.

Asked by: Shrub0
This will work well for home applications but is really designed to be used above 200 Hz due to the low Xmax and high resonant frequency.

Do these need a special gasket to mount from the front of a baffle?

There's a space between the flat where the frame meets the front section and the outermost rim. The center picture above shows the space. The mounting screw holes are in this space. When the mounting screws are torqued, it will tend to bend the metal in that space. If a gasket designed to fit the space was slightly higher than the lip, it would compress and prevent any metal bending. I have these speakers, and the lip of the rim appears to be the same height as the flat. Should I just go without the gasket and torque the screws carefully so as not to bend the metal?
Asked by: Pgoodwin1
The easiest thing to do is be careful installing the screws. I suppose you could use a gasket to prevent problems but we do not have anything specifically available for this.

Re use of the magnet?

How hard would it be to remove the magnet and put it on a different driver?I guess I am wondering what is the ideal process for magnet removal?
Asked by: Ray K
I like thinkers of this caliper , shows engineering thoughts in skills,,,,,HOWEVER,,,,, Unless six figure CNC machining tools and magnetic De and RE Gauss machine are at your fingertips, swap cannot be done !!!!Magnetic forces are so great its unlikely even able to pull thing apart by hand.If you tinker be careful not to get finger pinched between magnet and metal , magnet suddenly springing back wanting to regain natural poles. (been there done that, ouch!!!)Speakers are magnetized after fully assembled and glues cured. this allows top/ bottom plates, basket, magnet, and pole-piece assembly to easily align, impossible if magnetized.Belise Transducer Acoustics in Canada will DE-Gauss for a fee.

Loud using as mid in 3way

Is there a way to alter a DA crossover to bring down the mids using this driver in a 3way?Or, suggestions for a less-harsh driver as replacement?Thanks.
Asked by: wadefx
You usually want to find a driver with an SPL within about 3 dB of the others so this is not as much of an issue. You can use an L-Pad on mids and tweeters however, this will allow you to bring the volume level down to an appropriate level.
