Brian,
You should take Flodstroems advice and buy a pair of good used 2118h(s) as standins while you wait to obtain another 2108 .
The 2118 is a good speaker, which is why it was used as the basis for the 108H ( > used in the much loved 250ti series of speakers ) .
( As requested & fwiw ), here's a comparison made of the 2115 vs the le8t vs the 2108 ( using your Japanese source for my basic trace info ) .
- From the traces seen, the 2115 doesn't look very usable in my opinion ( > when using a standard 4315 network ).
- Now, that's only
"if this Japanese trace can be believed" ( which is in some doubt ).
FYI, relative levels for the 3
are not correct because the Japanese originator of the files referenced all his captures to a single 1K point ( instead of referencing to a constant voltage ).
- As an example, I would expect that the 2115 should be more efficient than the le8T in the mid-band area above 200hz ( but here it's not ).
What I've shown is only relevant to get an idea of the various response curves ( but not absolute levels ) & even these 3 responses are quite suspect since I notice his graphs all have a
common midband suck-out ( 400-900 hz ) for one reason or another ( I suppose it's a measuring anomaly ) .
PS: my vertical scale is purposefully somewhat "Hi-Rez" ( so as to hi-light the differences ) .
