...or why is it considered better?
Generally the cast frames are considered stiffer, not necessarilly better sounding. The stiffenss is desireable at high volume levels, supposedly it keeps the frames from distorting(out of shape) if pushed too hard.
For higher powered speakers of larger diameter a cast frame is desirable. Otherwise it's often just added cost (EDIT: and usually weight too) ... unless the driver it comes on is the only one with T-S parameters and specs that'll work for your application ; }
Thanks for the feedback. So it sounds like I probably don't have to worry about stamped frame drivers in a 2x10 250 Watt cabinet configuration then.
Nope : }
Cast aluminum frames are necessary with heavy magnets, more than 50 ounces or so, as steel would twist out of alignment. They're also a requirement for ultra light neo magnets, as they act as heatsinks for the thermally sensitive neodymium. They have no effect on sound.
Interesting... I knew about the 'heavy magnet' thing, but couldn't figure out why they would bother with those super sturdy frames for those little neo magnets.... heatsinks.... makes total sense.
The GK Neo 112 has a stamped frame...
Think it might even say so in at least one company's literature ; }
No picture of their drivers there. So I take it you've opened one up. Whose drivers are they using? Heatsinks or any venting tech there?
If you click on "specifications" it will show they are using stamped frame drivers.
Yeah. But no piccie - and de details are where de debbil lives or dies. Running a search right now ...
Cast aluminium frames also don't influence the magnetic field of the driver like a steel frame does, fwiw.
The Eminence Basslites use stamped frames and that's why they're only rated for 150 watts, they don't have adequate heat-sinking to handle more.
So far it's looking like GK and anyone not in the know who uses the Basslites will have a lot of complaints - right after the warranty expires ; }
Not necessarily, 300 watts is plenty enough for most 2x, and 600 is fine for a 4x, while 1200 is quite adequate for an 8x. Where I wouldn't use a Basslite is in a 1x, unless it was a practice cab or monitor wedge.
Well, you know 300 is enough, and I know it's enough. But -
The GK is 300watts at 8ohms into a 1x12.
I wouldn't want to be using a steel framed Neo driver with 300watts input.
