Kyle Posted May 27, 2021 Report Share Posted May 27, 2021 Looks like a new driver, not half bad on paper. Reasonable BL, not too too high mms. Price is solid too. https://www.parts-express.com/Dayton-Audio-MX12-22-12-Max-X-High-Excursion-DVC-Subwoofer-2-Ohms-Per-Coil-295-166 Quote Link to comment Share on other sites More sharing options...
lilmike Posted May 27, 2021 Report Share Posted May 27, 2021 Yeah, I saw that the other day. Plenty of motor, decent stroke, and reportedly quiet. Only real gripe after looking at the specs is that Le/Re is greater than 1. Still, it is a decent looking driver for the $$. If I needed a 600W 12, I would certainly consider it.

SME Posted May 28, 2021 Report Share Posted May 28, 2021 I wonder if "Klippel Verified" 18 mm Xmax includes Le linearity? I didn't see any mention of shorting rings. I wonder what HF extension looks like. Quote Link to comment Share on other sites More sharing options...
lilmike Posted May 28, 2021 Report Share Posted May 28, 2021 "Klippel Verified" means whatever the marketing department wants it to... The inductance isn't terrible (5.09 mH vs a 3.95 ohm Re), but it is no mid-bass. Things are rolling off after 100 Hz. https://www.parts-express.com/pedocs/specs/295-166--dayton-audio-mx12-22-spec-sheet.pdf I don't see any suggestion of inductance mitigation in that impedance plot, and the cutaways don't show shorting rings.

kipman725 Posted May 29, 2021 Report Share Posted May 29, 2021 I think from the datasheet the 18mm is when BL=0.7*MAX(BL). Looks like a great deal for the price, shame that price will not be anything like that in the UK. I wonder how it would do in a FLH like the lab horn?

Probably decent, the Lab 12 has great mms and BL for its size giving it a low Q so it would work well in a horn. I don't see any reason this couldn't. 1 Quote Link to comment Share on other sites More sharing options...
Ricci Posted June 4, 2021 Report Share Posted June 4, 2021 For the price these look pretty decent. The other option in that price range are the Type S 12 which has a lot lower motor force. Really the only thing the UM has going for it over this is the shorting rings and possibly lower distortion. The UM series gives up a lot of motor force and costs more though. Nobody really makes a 10" or 12" like I'd like to see. Quote Link to comment Share on other sites More sharing options...
