Any other part to replace on XO?

It was music...

Hey Sound was tested at 1 meter from speaker. I got a few peaks at 101/102 db , and beginning clipping. I need some more power to have good bass with headroom on those particular speakers. But, with speakers that have a more SET-friendly nominal impedance and impedance curve, I will get excellent bass with flea power. Dilemma. Or get woofer on ss amp/ biamp.... Had some Autoformers with Soundlab speakers and Atma amps years ago, thought it was a bandaid.

I logged many hours with Lowther drivers. ( Lammhorn, Beauhorn, Hedlund, Rethm, Medallion II). I rarely heard the Lowther shout, only on poorly built and designed cabinets. Tough to beat the Lowther speed and the dynamics are pretty good. Back loaded horns are not for everybody for sure. They sound fine in Oris 150/200. I am fond of 10Y, 45 amps. Tough to find a mid with such realism. I don't mind losing a bit of headroom and get some compression at high volumes. Compromises, compromises))

Well, well... That might be the case: "They are 4 ohms nominal, so already hard to drive; impedance in low frequency can probably get close to a couple ohms! Plus, after a search on this asylum, i read that Klipsch uses a measuring method that greatly beautifies the efficiency figures and does not reflect actual operating conditions. I am new to speakers and can't tell you what the various measurement methods are but that's kind of like of the infamous "musical power" spec for amps, which is peak power and gives power figures that are much greater than actual continuous power. Further readings indicate that SETs do not like driving crossover networks, so a dip into the full-range world might be in order. Line arrays are also a possibility . http://db.audioasylum.com/cgi/m.mpl?forum=hug&n=95435&highlight=forte Xo, woofer, radiator, low impedance dip ...might be a pain to drive those Fortes with a 3 watt 2a3 as opposed to a 99db single horn...

Yes it s RS.Battery is brand new.

99dB @ 1watt/1meter ....I run 45 monos(1,5W) with 104db speakers in my main system, they play loud and they are far to be underpowered.Wasn't the Forte designed around 2A3? It's a struggle to drive those Fortes to 90db.

Hi I got a pair of Forte II with a 2A3 integrated amp in a 13x11 room. The amp is around 2.5w. Using a sound meter, I get max 93 db max , having tried different cd players and cds. Bass is kind of shy, wondering what I should expect. Old caps in speakers? Thanks Jf
