Giskard,
I did a search for the ME150HSand it seems that you once posted the ThieleSmall Parameters and then deleted it again.

Why you always do that? Is there so much problems with copyrights to expect?

Anyway, could you please post again or PM me?

Thanks

I did not expect this:eek:

Red is ME150HS in 4343 Cabinet with original X-Over
Blue is 2235H/2231A in 4343 Cabinet with original X-Over

Would there be any sense to try a ME150HS instead of 2235H?

Is it the superior Transducer?

Not much is written about it.

Wouldn't the 2235 put out more than the 2231 at 20Hz?, at least according to JBL they do.

"I did not expect this"

What enclosure size and tuning frequency are you using?
5.6 cubic feet and two 4.125" ID ports x 8.25" ducts for an Fb of ~ 32 Hz right?

What is the DCR of that stock LF inductor or do you have a stock one?

"Would there be any sense to try a ME150HS instead of 2235H?"

If you have them then try them :)

Only if you spank it :p

How you know?;) ;)

I use the original 4343 network except the 2012 modification :blah: :blah:

If you have them then use them :)

I just fiddle around:p
I think they are hard to get.

I can measure all DCRs of 4343 network as soon as I'm ready to take them out again.

I had them out for the 2012 mod. and bypassed the 2405 section right then and guess what...
I did not measure the DCR of the coils to help everyone here :banghead: :banghead:

Hi Giskard,

thanks for providing more detailed parameters for the ME150H than in your reply from 7-23-2003.

However, there are some parameters that I don't know, namely "Rms = 5.708 mohms" and "Pe = ?". Would you explain their significance?

And at which frequency is Z measured?
