We can agrue about whos formula is corerct tho. The (Hvc - Hg)/2 one is technically most correct, but in reality the movement goes way beyond that point because of the inertion of the mass. The (Hvc - Hg)/2 point is where the VC starts leaving the gap, but no cone suspension/magnet force is able to simply stop the vc at that precise point. Some do it betetr, some worse, but at all of them the excursion simply dont stop there. ------------- Marjan Milosevic MM-Acoustics www.mm-acoustics.com https://www.facebook.com/pages/MM-Acoustics/608901282527713 |

Hey reality sound, nice idea, will add to that later. Suggestions: replace BL with BL/Re² to really be able to compare motor force between differenet nominal impedance drivers replace VAS with Cms for the same purpose (getting Sd out of the equation) State xmax as (Hvc-Hg)/2 as this is the only data every brand states add VC diameter and magnet type delete sensitivity as this only applies to the octave above EBP, so of no use for bass speakers. Maybe add EBP instead. |

Please dont let it get to you. I for one and I'm sure many others quietly read through the list with interest and appreciated your effort.

lots of talk about xmax.. there are also different behaviours as soon as xmax is exceeded. Some drivers sounds horrible immediately after that, some others can be pushed even further without too much problems like cone flapping/farting etc. That's why some real world comparsion / tests should be high in priority when comparing different drivers to each other. |

I have only ever heard cheapy Techincal Pro 21 (they were $125, had to try em...) 18sound 21LW1400 which are ok for the price. They were great till I put some REAL power into them, then they were TOAST. (stonelove few years ago- red-lining signal no doubt) 18sound21-9601- beast of a driver. Haven't blown one yet! Had 5 out for Mighty Crown last year (guys still talking about it) Had all 8 out for StoneLove summer gone. Not entirely impressed with them in my scoops though, even with 2k+ into each driver. They are now in Marjan's single reflex 21's running off a chinese LAB 20000K. Something serious. However winter time is upon us, very small window of time I have to build. Toying around with the idea of 21" folded horns (similar to Tony's) or some 21 hybrid hog like cab. ------------- When you gonna send me some $$ mate ? |

the NSW6021-6 looks like it beats the RCF LF21N551 in a ported enclosure. If it is doesn't cost much more in Europe - I can't see anyone with stock nb calculating xmax for the eminence driver from spec sheet data gives 19.4mm xmax (((Hvc-Hg)/2)+(Hg/4))

Hello, Was wondering if not the 21NLW9001 would better fit than the 9601? Looking at the tsp of both and especially the fs is making me wonder. Anyone has experience with one of both drivers or could explain the differences? 9001: http://www.eighteen.com/en/products/lf-driver/21-0/8/21NLW9001 - http://www.eighteensound.com/en/products/lf-driver/21-0/8/21NLW9001 9601: http://www.eighteen.com/en/products/lf-driver/21-0/8/21NLW9601 - http://www.eighteensound.com/en/products/lf-driver/21-0/8/21NLW9601 Many thanks

Looks like a serious driver but the price  For that you can have two B&C 18DS115 also available from Blue Aran, pro's and cons but even so it seems like a hard sell.

The price is the main problem in the EU. The US price of 750 dollar is definately more affordable. Regarding performance it comes just under the 21iPal (so very good). Personally I just went for Lavoce SAN215.30 drivers, those are half the price of the NSW.

Well the principle is same as with our 18 inch subs, the M4.18. Those were released back in 2014 and Ben (RealitySound) has also a substantial number of those too. 21s surely needed more internal volume and it was only natural to simply go longer. Since RCF LF21N551 (originally used in the M4.21) was discontinued, the Eminence was the logical choice for an ultimate weapon. Yeah its not cheap, but at 2500W the driver has still 4mm of x-max left in our box. Unlike the RCF which was at he limit or any other 21 that i have simulated. Ben, send me some better pictures man. i need to brag about this all over internet :) Oh, i almost forgot. One of the reasons why i chose this shape lies within EAW SB1000 that i used a lot back in the days. I always loved the small front format. It allows you to place more subs in smaller frontal area.

Heya. How come they discontinued the beasty LF21N551, and all that without any substitute? I'm trafficking two pieces now, and they are awesome. Will gonto up-to 20.5mm excursion before they start to really struggle with noises and thermal compression from suspension, way better than 21DS115 I had before.

Heya. No, I haven't. It certainly has predispositions to be better. Everything on the driver is at least half class more massive. And it is kinda downfall of the driver in my approach. I need compact mobile bins. Eminence does not support that, while RCF just barely does. Maybe a massive 18“ driver could do that. But Eminence 18" nsw is nothing like its bigger brother. And Eminence is quite expensive in Europe. 18IPAL with its 4.5" Al coil is not that tempting for the price either.

Wow that is unexpected. In our country, it was priced right under IPAL, maybe $200 on already overpriced $1350 product, so I thought it was not that price competitive on the market, or maybe some reliability issues. But RCF pulling that product because it is too good, that sounds rather evil.
So I guess there is nothing like new IPALs or smaller M-force drivers on horizon. Saaad times. Anyways, thanks for the info. ------------- Nikon and Canon people should not be married to each other. Why did you let this happen? |
