HF pot casting

Bump

This came up in another discussion.

Just to clarify then, do the 288K/L and 299s have the 'large pot' or not? Was it a test during design, or a cost reduction that remained in those drivers, as opposed to the 288Gs.

I gather that the flat pancake 399s do not just by their size.

All the 200 series (288/290/291) have the rather noticeable ~10 lb pot. The 300 series (390/399) doesn't.

The 300 series is another example of GPA picking up where Altec left off. GPA's vintage series gets back to the good stuff.

So you are saying my new 399's from GPA aren't considered as good as "The Good Stuff?
Hah, stupid me! I thought I was buying the best... :(

Perspective . . . Let's keep this in perspective.
If, and I mean IF the larger pot reduces distortion, it will be at high power. Much higher power than any of us will be using for home stereo. A 399 driver on a MRII horn will deliver about 110dB at 1 watt. How much loud do ya need in yer livin' room???

Buy the older stuff because it's cool and sounds great.
Buy the newer stuff because it's got a better price and sounds great.

Couldn't agree more.

I only hear that bad sound from the JBL pancakes when they are cranked in a large cinema.
