But by your definitions this is a large chamber scoop and pfly is talking about a BMS neo driver, not a B&C.

I'm not about Nd in this but I honestly believe that BMS 18N860 is one of the very very very top sub drivers today, regardless of magnet material. Like all drivers, it won't suit every loading technique, but general quality and performance should be top notch.

Typically, drivers suited to scoops fall into 2x categories, those perfect for small chambers and the rest. So you are more likely to hear about small or medium chamber scoop drivers. Mentioned B&C, as that is also a Neo that on paper/Sims seemed to excel, however actual performance in scoop was very dissappointing. Point being, time has shown, simming Neo drivers in scoops, is "often" pointless, proof being in actual listening, as opposed to simming ferrite drivers, you will often get mostly accurate approximation, of real world results. |

to be honest i'd ignore Hornresponse altogether.
it is unable to really tell how it is going to sound. the best example being: sim a Turbomax 1800 in a medium/small scoop and the sims say it would be awesome, but we all know these drivers need more than a big chamber, so it seems, otherwise they sound like a bag of spanners. i can only think of 2 common drivers that truly work in tiny chambers with 10+mm xmax, thats the PD1850 and the V18-1000. btw those scoops look cool - did you leave the lip around the rear of the box to provide a handle all the way round for when it's on castors?

I personally would not use the 860's in anything but a large BR when you need its ability to go very low, Cinema Subs etc.
However in large chamber Scoops the 850v2 works very well. No idea how it compares to the Tmax etc etc never compared them, only with the Void 1200,s. Maybe do a comparison one day. Tony |

another measurement bump, this time outside, with 2nd and 3rd harmonics. For many reasons this is much more accurate than earlier

The response measurements posted above are impressive as very few scoops will go below 40Hz. 30Hz is quite an achievement. Was the scoop placed in a corner when the measurement was made?

All measurements done with a stack of four. Indoor measurement was done near back wall. Low-ish ceiling.
I'm more impressed with the distortion figures. I think these things sound phenomenal. They are definitely sub box with little "kick" available, but in 30-80hz range they sound fast, precise, warm and smooth. Not as "clinical" as Lab, but still there is plenty of detail that for example Meyer 700HP wouldn't reveal. Also I can give them everything that Infinite 5 bridged per pair can give and they don't show any sign of stress what so ever. Edited by pfly - 02 August 2011 at 5:05pm |
