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.

Celestion Neodymium 5" Full-Range Woofer 8 Ohm

For an electric guitar small table top 2 watt tube amp set-up. ...  Would this speaker be better suited for a sealed enclosure or an open set up ?

Asked by: KPM61
It will work fine for either application, it really depends on the type of sound you want to get from it. You can try it either way for experimentation.

I want to use this speaker with dual 8" Dayton Classic and a dome tweeter in a 3 way project with custom made crossover crossed at 800hz - 3.5 khz. Would this driver be a good options for power handling up to 150 -200 watts for the whole system?

Asked by: markpen883
Yes this will be a good choice for a system like that.

Zobel Network needed as mid in 3-way?

I would like to use this as a mid crossed at 500hz and 4000hz. Based on the graph (and assuming it is showing double the ohm-value of the actual impedance curve), the higher crossover point would be in the 12 ohm range.Would it be beneficial to add a zobel network?
Asked by: Tha Scar
I don't think so, but a listening test would tell you. A Zobel network is used to flatten the tendancy of voice coil impedance rising with frequency. Where this is most beneficial is in woofers. Taming impedance rise in a woof helps by reducing highs, as I understand it.Using a Zobel on a mid in a three-way wouldn't, in my opinion, make much difference given the lmited range in which the mid will be used.The Zobel is used AFTER the crossover and acts as another filter. I always try to REDUCE the component count as much as possible. Sometimes what you're trying to cure is not as bad as the side effects induced by the cure.You're the one who has to be happy, so build one and see. I vote no though. Hope this helps.

Would these work as a midrange replacement on a Design Acoustics PS-10a?

I bough a pair of the DA PS-10s at a thrift store and they need new midranges. Would these do?Thanks,Richard
Asked by: RJP V
Assuming the physical fit is appropriate these will work as replacements for those speakers. Some cabinet modifications may be required for mounting.

Does this driver have a pole bore (vented)?

Asked by: Dirkl
even more important is,"is it blackened"?ventilation only helps with commensurate convection for dissipation.and isn't dissipation what were really after to counteract inefficiencies?
