Are you telling me JBL is a liar? - Leo loves music 12:58:43 05/26/25 (10)

10db down at 35Hz. Nothing else needs to be said.nt - Tre' 14:27:58 05/26/25 (9)

You forgot one thing - 100dB sensitivity! (NT) - Leo loves music 14:51:13 05/26/25 (8)

So are you now saying you use heavy EQ to get your speakers flat to 35Hz? - Tre' 15:17:40 05/26/25 (7)

RE: So are you now saying you use heavy EQ to get your speakers flat to 35Hz? - Leo loves music 15:23:25 05/26/25 (6)

If you're not using EQ then your JBL speakers.... - Tre' 17:35:02 05/26/25 (5)

Do you really expect a 100dB speaker to go flat down to 20Hz? - Leo loves music 17:49:45 05/26/25 (4)

Absolutely, Altec A2 _nT. - Cleantimestream 21:27:09 06/03/25 (0)

No I do not. I thought you did. nt - Tre' 17:52:43 05/26/25 (2)

So, how low can a 100dB sensitivity speaker go? - Leo loves music 17:57:31 05/26/25 (1)

OK but I'm not clear what that has to do with your speakers. - Tre' 10:39:38 05/27/25 (0)

JBL didn't lie - Tre' 14:43:00 05/26/25 (1)

In later years JBL chose longer excursion for power, harder to drive than most people think. Efficiency.... - Cleantimestream 08:38:40 06/05/25 (0)

What tube are you using a 1250 ohm output transformer with? - Tre' 11:54:09 05/25/25 (9)

Thanks, now it makes sense. Parallel 300Bs are very different than a single 805. - Tre' 12:07:09 05/25/25 (7)
