searching a non very expansive 18" double coil sub

[inertial]

hi ,
I have a 97 litres sealed beautiful cabinet very strong, that need a 18" very low Fs and large Qts imho end high Cms too, plus very high Mms i think.
I am not interested in frame coil diametre , max power ,Xmax , etc, only cost and the" right" T/S parameters to go approx Qtc about 0,7- 0,9 in 97 litres 100% stuffed fiberglass and Fc and F3 about 35 Hz or less.
Vented eventualy is possible ( a 5,5 " pipe is sufficent imho).
I do not have found nada if not a monstre TC sound (or similar) at 800/ 900 USD :-(, that is the double or the triple of my poor budget .
Thanks for help nd every comment will be very appreciated ! 🙂

Cheers

Awkward. 😱
Let me ask, why is that?! And if you don't have the money why looking at such a system in any way related to the TC sounds.
An 18" doesn't go very low and a 97L enclosure might be a very small box.
To solve your problem maybe you can use a 15" DVC or a double 18" driver system. Also good 18" drivers are:

BMS - 18N860-/862 - Look at their project here
Eminence - Omega Pro-18
Beyma - 18G40
B&C - 18 PS 100
Eminence - Delta Pro-18A
Eminence - Sigma Pro-18

Woofers • 18" • Europe Audio
Subwoofers • 15" • Europe Audio

The Stereo Integrity HT18 might meet your requirements, provided it's available where you're at. Some measurements.

Good point Diogenes, the SI's are not so expensive and can be ordered Online.

hello,

Since inertial is from Italy, Monaco SPH-450TC would be a good candidate.
I use this one for home cinema, it's a very good sub with a strong motor and the price is low.
I got it from Germany, best pricing. (eBay 😉 )
Qtc in a 97l box would be 0,616 with this woofer
Qtc 0,7 in a 69l box

Vented in 90l (accounting for port volume) and tuned to 31hz (lowest note on a double bass guitar)
If also used for HT, use a HPF.

double coil 18 sw wanted cheap but good

Hi, thank you guys for the help! 😉

I am in favour of the eminence double coil vented or, better, much better for the Integrity sub, a real monster to my poor eyes!"!
one pound of Mms!!! good for little closed box as mine! 😎

This woofer is amazing IMHO, but they claim must be ordered and wait for 4 months!! 😱

OK, if this is the standard procedure...
Where they produce it , in the moon?😀

But they are rookie factory or expert ?
162 usd are over my desire and I am propense to buy one tomorrow if you give me "techinical OK", I never seen this company.😛

So thanks again but one more question: ok, it is only a sub belowe 100 Hz 12 dB octave low pass, but 440 gr Mms isn't too much also with strong motor ( B&W 15" are 350 gr MMs and they fire up to 350 Hz but IMHO do not sound "fast"...🙁

Hi Paolo,
What is the eminence double coil vented model? Thanks.

 

[inertial]

Sorry, I have confused. They are all single coil, except the Integrity.

Bye!

Why do you need a dual coil driver?

One amplifier to drive one Voice Coil seems a natural combination.

large Qts .............Vented eventualy is possible

This seems an odd outcome.
High Qts generally does not suit vented cabinets.
Unless you plan to correct the anomaly with a Linkwitz Transform.

Hi Paolo,

Still looking for a Driver? Have a look at the submitted calculations that tries to expand your given requirements to a more complete set of Driver T/S worth looking for..

[inertial]

Thanks bjorn, but I know the calculation procedures.
I only need a double coil woofer.
For the moment in Italy I have found Ciare HS323 (if I remember correctly) that is good for a B4 reflex in about 65 liters, with the added parasitic resistence of the coil in series for low pass. It's not optimal but I have more liters of minimum so I can go.
And it costs about 220 Euro. It's a 12".

Thanks for reading.

 

[Inductor]

It's a 12".

Thanks for reading.

From someone that was looking for an 18... 😀

 

[inertial]

Indubitabilly i prefer a 18 " instead a 12 , because 97 liters closed 100% stuffed is more right IMHO.

Someone know KCS woofers professional ESPANOLs ?

A friend of mine would be sell to me for a fews euros a 18" double coil swf KCS, but I am not able to found any link to raw drivers, only speakers.
If someone kow I will be very happy, T/S parameters would be very important for me! 🙂

In the meantime have a look at this 18 Sound 18TLW3000. Make sure it's a DVC, as you need.
I know you might find it more expensive or uplevel. If so look at other JBL's GTOs type car subs. Their Fs is low and not so pricey. 😀

18 Sound 18TLW3000 Tetracoil subwoofer - YouTube

Maybe it's the same they used here
KME QLB 118X Passive Sub - pdf

Also make sure Sica or B&C doesn't make any DVC. If resourced in Italy you may save in taxes/transport. 😎

Why do you need a dual coil driver?.......

Has anyone got an answer, since the OP has not given any reason?

 

[Inductor]

Have no idea. Just for the sake of simplicity, with two amps/stereo satellites it's a good answer, no?!

 

[AndrewT]

Maybe.
