There is a big difference between one woofer FLH and dual. With the openness, one woofer is not sufficient outside a closed cabinet. But closed cabinet worsens sonics, so to have that openness with more weight, two 15 inchers are required.
Many Altecs can be shouty, and quality of Altec set up varies a lot.
Iām always intrigued by what the desired result is replaying something like the Metallica. Are you trying to recreate the sound of the musicians as they were sounding in the studio maybe through their practice amps, or the sound that was heard through the monitors by the guy at the mixing desk, or as the recording was heard when played through the monitors in the mastering studio or indeed as it might sound played live in some large indoor venue or indeed outdoors at an open air festival? When you put that record on & plonk yourself down in front of your speakers which sound are you hoping to recreate?
I listen to Metallica now and then on my system. Never been a fan of trying to recreate anything tbh because I donāt actually enjoy live music that much, listening to studio albums is what I prefer. I just put it on to listen to Metallica tbh
Metallica is an interesting one to me. Things like the Black Album were heralded as a āfinally well recorded heavy metal albumā, but actually itās really not great IMHO. In spite of the music style, itās very flat sounding and really lacking for punch and dynamics. Itās most bizarre. I think it was on Peteās 16A that I first heard this and had a proper āWTF?!ā moment. Heard it on a few things since and same issue. And obviously the 16A sounded fucking sublime when we stuck something else on too.
The point Iām making is how do you know whether whatever system youāve got is doing a good job particularly if playing something like Sabbath, Metallica, AC/DC etc? If people are trying the recreate the experience they had seeing them live at Reading or somewhere (because it was a blast) or whether theyāre trying to get it to sound like they imagined it might have in the studio.
You set up the system to play classical and jazz and then play rock on it, but it should play rock too. You donāt need the exact venue feeling but a general facsimile. I have watched live ACDC thrice (once with Axl Rose), GnR Thrice (once with the Slash reunion), Black Sabbath, Sound Garden, Deep Purple, Iron Maiden once each, Eric Clapton 5 times, and my favorite, a Led Zep cover band thrice. Imo, a good dual FLH followed by big Apogees do rock the best.
ps: Megadeth and some well known rock band of the 90s covered for ACDC so got to hear them too
Love me my name tag line, āother peopleās horn specialistā. Whichever mod changed it has a great sense of humour even though might not have a sense for hearing nuances in videos.
