radulescu_paul_mircea Posted April 4, 2017 Author Share Posted April 4, 2017 They have opened it . I've seen a pic last year but now it's clear Edit: in fact that is their new bass reflex m force sub Quote Link to comment Share on other sites More sharing options...
radulescu_paul_mircea Posted April 28, 2017 Author Share Posted April 28, 2017 So I heard these for the first time. They are more than wonderful. That system goes down to 27hz clean and immensely powerful.they are so loud I was shocked. I heard the Danley BC218 last year but these are in another league. The cabinets are rock solid, even the back wheels inspire quality. The amp is clamped on in the back but they didn't make a personalized case for it Quote Link to comment Share on other sites More sharing options...

I've been hearing that the DBH218 is a really good cab. Quote Link to comment Share on other sites More sharing options...
radulescu_paul_mircea Posted April 28, 2017 Author Share Posted April 28, 2017 The DBH218 sounds very nice, but it's more of a 40 hz horn. This year at Pro Light and Sound they had 4 of them with a J3-96 each side of a stage but I wasn't there so IDK how they sounded. Last year they had 2 BC218 with 4 DBH at the ends of the stage with 2 SH96HO. Those BC are crushing but these M-Force horns are over them Quote Link to comment Share on other sites More sharing options...
peniku8 Posted November 25, 2019 Share Posted November 25, 2019 Looks like there is a 50" M-Force being produced for club/home use. https://www.aia-cinema.com/references/detail/fidelity-40-ascendo-immersive-audio.html Quote Link to comment Share on other sites More sharing options...

The Funktion One horn's stats are not all that impressive when you look at the humongous size of the thing. iirc it's over 1000L and like 300kg, but if you look at it as what it is (a single driver subwoofer), it's ridiculous. I would also love to experience the Mover. The motor is similar to the M-Force in design. It generates enough force to lift my entire body. I don't know how many motors are that capable 😅 Quote Link to comment Share on other sites More sharing options...

Neo motor and 8” coil. I heard the M-Force more than once and it is absolutely amazing. Unfortunately the users had some unlucky situations with them but they indeed perform extremely well! that Funktion one sub is the loudest sub out there !period ! and it digs deep enough to be extremely impressive. It goes louder under 50 hz than 2 SKhorns XL loaded with Ipal and used with other subs from 60 hz up they will have enough headroom. There are a few companies who have 6 and 8 of them in use constantly with great results. Quote Link to comment Share on other sites More sharing options...

It's surprising that one of these subs is louder than 2 of your subs, the stats would tell a different story. According to hornresp, 4 IPALs should exceed 140db playing at their AES wattage from 30 (tuning frequency of my design) to 200Hz. Total volume being less than 1000L; 135db at 25Hz (excursion limited). Josh please get an F132 and do some CEA tests ❤️ Quote Link to comment Share on other sites More sharing options...

peniku8 Posted November 26, 2019 Share Posted November 26, 2019 I've been wondering... What if one took like 5 Movers and attached them to a piece of plywood (one at each corner and one in the center). Then mount this to an infinite baffle construction and seal off the gap with a rubber surround... The surface area of a 2.5m x 1.25m sheet is equal to about 20 21" drivers (if you add half of a decently sized surround) with an Xmax of 15mm. Even if the entire thing would probably not be able to widthstand acceleration forces to get maximum excursion at say 40Hz, this should be a pretty efficient solution for single digit extension in any home theater. 5 movers have a total peak force of 4.5KN, which translates into an acceleration of 180m/s² of a 25kg mass (estimated weight of a 12mm thick sheet of BB ply). With an acceleration of 180m/s² you could move an object 15mm (Xmax) within ~0,013s. Since you need to do that 4 times to get a full sine wave cycle, that would result in a frequency of about 19Hz. And that only with 5KW if I'm interpreting their data sheet correctly. You could make an entire wall your cone area with enough movers...

SME Posted January 8, 2020 Share Posted January 8, 2020 Is that a sealed alignment or something else? It sure does drop like a rock below 20 Hz. Quote Link to comment Share on other sites More sharing options...

It's a little hard to figure out what's going on. The longer I look at the picture, the more confused I get. What looks like horn folds seems to be bracing. What looks like vents (bottom corners), seems to be a dead end... Quote Link to comment Share on other sites More sharing options...
Ricci Posted January 8, 2020 Share Posted January 8, 2020 I think it's actually a TH variant. It is hard to tell for sure from the angle of the image but it looks like the driver fires into a throat where the motor is this then splits to the left and right and travels up, down, forward back up and then out from the top of the other side of the driver. I think! It's really hard to tell for sure from the pic. Anyway I'm going with a TH. Quote Link to comment Share on other sites More sharing options...

The EQ might help with smoothing response, but what about overall bandwidth? I could be wrong but to me the response looks TH like after a liberal dose of DSP. There's a notch and a small peak in the 65-80Hz area. A tuning at 20Hz or just above would likely put the "spike" in the 70Hz range. The M-force drivers don't model normal either due to the motor force. Quote Link to comment Share on other sites More sharing options...
kipman725 Posted January 9, 2020 Share Posted January 9, 2020 Based on innovative M-Force® transducer from Powersoft®, THOR employs transmission line acoustic design, called in to maximize the performance and deliver otherwise unachievable SPL and frequency response. TH then, Stuffing? Quote Link to comment Share on other sites More sharing options...
Ricci Posted January 10, 2020 Share Posted January 10, 2020 Probably...Either way the rear wave of the driver is exiting back in front of the driver and the driver is offset back into the enclosure a bit which is TH like. Somewhere between a TH and Tline seems to fit. That is a huge driver and a really big enclosure. Should make some noise. Quote Link to comment Share on other sites More sharing options...

peniku8 Posted December 4, 2020 Share Posted December 4, 2020 I saw this on IG earlier, but I scrolled so fast I didn't realize it was a whole new design, I thought it was a slight redesign of the existing model. Stats are insane as "usual". Re of 0.26Ohm thou? Recommended to run two series drivers off a single X4L channel (which is running in bridged configuration)? BL²/Re is 1700, but the data sheet says 1600 and that T/S params are not fully accurate for the M-drive type transducers, if I understood that correctly, but holy cow. Has as much surface area as two 21" drivers. Does 5KW. I'm just not fully understanding the sensitivity ratings. Either way, 94db at 0.5V is pretty impressive for a 2.5kg moving mass. Do I want one? No, I want 10. Quote Link to comment Share on other sites More sharing options...

How was the M-Drive set up, did it have an additional heatsink/ventilation or just the module by itself with its two small fans? Quote Link to comment Share on other sites More sharing options...
