Cubo 18

The 18NLW2400 is an 18 inch extended low frequency loudspeaker designed for high SPL subwoofer applications in either a reflex, bandpass or horn loaded configuration. Compared to our industry standard 18LW1400, the 18LW9400 provides higher maximum SPL, increased program power handling and lower power compression. In order to furtherly increase power handling and reduce power compression figure, 18NLW9400 uses the same voice coil ventilation technology developed for our flagship 9000 neodymium transducer series. 

Apparently, they couldn't choose it's final name then. Now it's known as the 18NLW9400

Both the Ciare Cw455 and the 18NLW9400 will work best in Cubo 18 Extended.

Best regards Cubo

thank you very much Mr. CUBO. anyway I was wrong to write. I have the 18NLW9400, so it will work fine inside

Hello, MR.Cubo
Trying to build the cubo18 not sure which of the two I should build
the drivers in my price range and in stock are

JBL. 18SWS1000

SWLENIUM 18SWS1000

CELESTION FTR18-4080FD

EMINENCE KAPA PRO

CELESTIOR. CF1830E

Hi All,

So after faffing around for too long I missed the boat on the 18nw100 availability and they're now on back order for at least 80 days from one of the few places that ship to NZ I'd heard some positive things about the 18TLW3000 en.toutlehautparleur.com/18-sound-18tlw3...r-4-ohm-18-inch.html but it EBP (as you've defined Fs/Qts) is only 91hz. Is this going to make it a non-starter? Very open to other suggestions - am trying to balance getting something that will work well in the Cubo 18's (which I have the wood cut and ready for) and be ported into one of the paraflex designs once the price of timber goes back down in NZ (3 sheets per box at $280nzd a shot is a bit nuts!)

@Dave305: From that list I would choose the FTR18-4080FD, it's a good driver for Cubo 18 Extended. I think you also e-mailed me that you wanted 30 Hz performance, in which case you're better off using Cubo Sub. However the FTR18-4080FD might be on the light side for all day 30 Hz performance (couldn't find Xmech though).

@Jack: The 18NLW9400 is the 18Sound equivalent of the B&C 18NW100, both rated at 1200 W AES, it would be my choice with an amplifier of roughly 1200 W or less. The 18TLW3000 is a very high power driver, with the 4 Ohm version looking best (better than the 8 Ohm version), it's a good choice if you have around 1800 W or more to power it with.

Thank you very much, I`ll send you pics and keep you posted

Hello, have anyone Test the 18 Sound 18NTLW5000 in die Cubo 18? Or can say if the ntlw will work in the Cubo 18?

Thx

The 18 Sound 18NTLW5000 does not fit (under normal circumstances) in Cubo 18, mounted with the magnet in the horn, due to the driver depth. However some changes can be made to make it fit. It does fit mounted with the magnet in the chamber, with some minor changes.

It does work best in Cubo 18 Extended, if you need help with making changes so it fits, send me an e-mail at: questionsaboutcubo at gmail dot com

good morning when mounting the speaker backwards (magnet out) on the Cubo 18 do I have to revers the wire polarity?

I never reversed polarity with the magnet visible (it sounded fine to me) but it also depends on the tops you're using, so you can always try both ways and have a listen.
