Celestion 5" on sale at PE..
 
This looks to be a non-starter for Celestion due to it's neo motor and the rising cost of Neo.

It's based on the TF0510:

LF Pressed Chassis / Ferrite - TF0510 - Celestion - Guitar, Bass & Pro Audio Speakers

BUT.. it seems to have a more extended upper freq. response (..perhaps due to a stronger motor).

Overall good linearity and nice low mms as well. :cool:


Anyway here it is:

Celestion Neodymium 5" Full Range Woofer 8 Ohm 299-416

What sort of design would you recommend for this driver? (I'm very new to reading TS parameters). Seems like it would only really work well in a 3-way setup.

Because of it's high fs it's probably best suited to a "FAST" design - where this is a full range and another driver is added in for midbass section, particularly near the baffle step pressure loss region.

It could be in a box.. or even a large panel for OB.

You shouldn't listen to this driver to far off-axis or you'll loose the near 13 kHz + of highs it reproduces. Say ideally perhaps about 5 degrees off axis, either "toe-in" or "toe-out". Its treble response is actually better than many "fullrange" drivers.

Alternatively it could be a nice extended midrange, with something like a cheaper small Dayton Audio tweeter to accompany it (..and a basic 1st order high pass higher in freq.).

I suppose with a bit of "massaging" you could get your "baffle step loss" compensation and a bit of added low freq. extension via a back-horn, but that would put it's delayed output in the midrange - NOT a good idea.

You could also get a bit of extra extension with a Bass Reflex design.. just plug the T/S params into WinISD standard to model that, BUT you wouldn't have any baffle step compensation. (..though the Edge baffle model program can help you with that.)

Lot's of options! :)

The top end on this driver looks pretty "nasty" lots of cone "break-up"! I don't think I'd be tempted to try it!

As opposed to other "fullrange" drivers with so much smoothing applied that their treble response *looks* respectable? ;)

Hi,

Would be decent midrange in a high senstivity 3 way.

goes high enough, clean enough to mate to a good cheap tweeter.

rgds, sreten.

Though they are very good FR for the intended purpose, acoustic guitar.

celestion 5"
 
Looked at this for use in TABAQ but low Xmax 1.13mm might limit the low end.
Still,a decent buy at $8.

Hi,

Its probably quite a bit better than your average Fostex.

With a 5mm gap and 7.3mm coil, the 1.13 mm linear
Xmax is one way, bothway it is 2.3mm, and it will do
probably the same again with modest bass distortion.

In 2L to 3L sealed its basically a midrange, but could be
used for AV with a (>) 80Hz filter in 7L tuned to 90Hz.

(Again this tuning is near ideal for acoustic guitar.)

Same sort of thing would apply to any TL/MLTL loading.

rgds, sreten.

Nice driver for $8, for the top end you really need to see
the set of of of-axis curves to judge 6KHz upwards.

Hmm it was on sale for $8 back then, now on close out for $12.9. I thought I got a good deal lol just ordered a pair cuz I needed $25 more spent for free shipping.
I had a $5 off code, so figure at $20 for the pair it wasnt too much of a hit.

Now what should I do With these?

:D

I'd expect them to do rather well in a small-ish boombox, crossed to a cheap tweeter.

Go ported, tune for a bump in the 80-120Hz region and you're good to go.

In fact, put a pair in parallel for a 4ohm load, then you can bi-amp the tweeters...
