Dear @bstbomber : Yes, you are rigth the monitors in the 1812 were the BC8. I own oll LP Telarc recordings where Telarc used not only the 2030's but the 1530 that uses the same 2030 tweeter/main Midrange.
@tomic601 , you are rigth too the big enclousure in the 2030 has several problems and I took some actions about and I received advise directly from M.Kelly.
The tweeter/main mid range in the 2030's are really something exceptional even today. No, my modified L-2030 certainly is not a perfect speaker but performs at very high quality levels that are unveliable for a true vintage design.
Congratulations to A D S .
