I agree whole heartily! Perhaps something similar to the original Avalanche series with a little more BL (especially for the 18), at least 30 mm of Xmax, better upper bass response (lower inductance),all for a somewhat reasonable price point ($275-$350).Not sure if that is reasonable:dontknow:, but it sure would be cool. :yay:Oh goody... I get to post first. :bigsmile:
These are the properties that I'd like to see on a line of HT drivers. I'm one of the people who is willing to pay a bit for some extra quality so budgetary concerns aren't really on my radar.
High displacement for the low bass in soundtracks and low distortion, with high SQ and good upper end bass extension for blending with the mains. Versatility so that they can be used in resonant and sealed designs, with an emphasis on small sealed box requirements. 30mm or more one way would be great and the more the better. It doesn't need to be as crazy as a XXX, but massive displacement headroom and clearances like that is a plus. Keep it linear and low distortion too. I'd like to see a linear motor system used (split coil maybe/ counter coil?) to that end. Quiet high excursion operation. Also low and well controlled inductance through whatever means necessary(shorting rings/ counter coil, whatever). Solid venting and cooling with high thermal power handling. High BL to keep the efficiency up and the box sizes reasonable. I know that using a linear motor automatically hurts you there but it can be done. I'd like to see it have a neo based motor too. Finally, keep it plain and classy looking. Offer it all the way up to a 21 or 22" like the one we already discussed.
That'll only be what? About $1500 per driver? :thud:
1. Extreme linearity/High displacement
2. High BL
3. Well controlled inductance
4. High thermal power handling/venting/cooling
5. Low self noise at high excursion
7. Reasonable box size requirements
9. Classy looking
Perhaps you could do 60% of that in a more budget oriented line?
What were you thinking? A driver that could out-do an LMS or a more economical series that has 30+ mm of x-max & lower inductance?.........Is it too much to ask for a little efiiciency too?:whistling:I actually had a chance to do some FEA for this last night and came up with a nice little solution (havent had a chance in long time to do FEA for fun...) I definitely think we can meet those goals at a reasonable price point. Only sticking point is the baskets... but I do have a solution for that as well with some plate and one of the CNCs Need to check on a patent as I have a feeling that there might be something covered on how I want to do things already. If not, Ill see about getting one going.
I know, I know, but he did ask you know!:heehee:Robseyes,
Getting decent efficiency (low mms, High BL), really long linear throw and low inductance all in one is the ticket...usually tricky and expensive to do. Some of these fight against each other.
I checked out that M16 driver and it looks pretty nice. I can't believe I've never even heard of that one. Looks like it's either DD or split coil, field serviceable, machined frame and all of that. I really couldn't find too much info on it. Just a few pictures. Woofersetc show it in stock though. I don't see how they could patent that basket construction method really. It's a nice frame but it's not like it's an invention or anything. It's just a machined frame instead of the usual methods. You obviously wouldn't copy it just build yours the same way.Lol... I definitely dont work that way. I give credit where it is due, or figure another solution. I had heard mention that there was a patent on the Alumapro M16 style basket for its construction. I havent found anything, but will absolutely exhaust my search ability and that of my patent attorneys before I sell a single thing. While my design is no where near the same as theirs, I do need to see what the patent covers should there actually be one.
