2245H reconed as 2240H what is the result

[mbottz]

I am looking at a speaker which has the 2245H reconed as a 2240H. What is the effect of such a transplant? Is it good or bad? Anyone know the answer?

Thanks

I'm fairly sure that 2245 and 2240 are same cores.

I have 2245 cores that have been reconed as 2240's arriving next week and will let you know how the results are when I have a chance to play them awhile.

A 2245H reconed as 2240H is a 2240H.
Ok, except the foilcal.

As a subwoofer is the 2245 superior? Is it something that if played side by side in the same type enclosure I could hear a significant difference? What does it do to the value of a B460?

Thanks

For home use? I'd say yes.

...hear a significant difference?

or feel, ... most likely.

What does it do to the value of a B460?

These are freshly reconed and have not been broke in yet:

I listed the serial nrs that were used for the 2245 since I wanted to keep both identifiable.


JBL 2240H #24026 2240H #24010
Fs 31.68hz ---31.2hz
Qes .32 ---.31
Qms 7.2--- 6.8
Qts .31 ---.3
Le .87mH--- .87mH


It will take me a few weeks and break them in before they each get their own 8 cubic ft ported cabs for LF duty between 40hz and 200hz.

My room is so small that I don't worry about loading down below 35hz. The living room will not energize with those low notes, but the garage, kitchen and outside will!!!
