Hi, all,
I have all the pairs of three drivers (LE123A1, LE5-2 and Le20-1) and I am on the way to build a system for tube amplifier. And I have never heard to original L100 monitors.
What is the best way - to follow exactly L100 design (same enclosure dimentions and X-over), or to make the bigger box?
It may look as stupid question, but I am confused. The measurements show for LE123A1 Qts=0.5 (0.52 the second driver) and Vas=250 (220 the second) liters. Almost same data as from JBL specs.
However, original L100 are very small for these parameters. In a box of about 60 liters it will be Fs=57 Hz, Qts=1.18 (for tube amp even more). This is all very strange for me: how then can these speakers produce deep bass? The modern approach instead says the bass must be abuzzing and boomy. But many people say they love L100 monintors, and L100 were very sucessful speakers, they were studio monitors etc...
On the other hand, JBL ALpha SIII speakers with same drivers (and passive radiator) have more "approapriate" boxes - much bigger, and even X-over look more realistic - with Le bass unit compensation and flattering the increasing responce of LE5-2.
Too many questions for me.
Whould You please help:
(i) is it worth to follow exaclty the L100 design (same box, same driver position, X-over etc)?
(ii) is the bass in L100 really fantastic as people say? I can understand "there is a lot of bass from L100". But is it fast, clean, dynamic, accurate, not boomy?
(iii) what would be the best enclosure volume with this driver if the speaker size is only on the second place?
Thanks,
Alexander
