Hello,

 

what’s your experience with the RL 140s and home cinema setup? I’ve recently refurbished my pair (woofer surrounds, re-capped). The music generally sounds good, but when watching TV the “s, c, f” sounds are really hot. I’ve played with the EQ, but still not much luck. 

Is this usual with the RedLine speakers?

on the separate note, the twitters sound a bit echoey, but both are rather similar. Is this normal? 

any ideas? Thx

Did you use the same value capacitors? Did you use electrolytic or film?

What amplifier are they connected to?

How is the TV connected to the amplifier? Is it only when watching TV channels or also when watching a movie from e.g. streaming or blu ray?

Thanks for getting back.

Same values, electrolytic. 

They’re driven by Harlan Kardon AVR 151 (75W channel). It’s all over HDMI, 2 channels stereo. 

It’s generally with spoken sounds. Definitely TV (over DVBT) is the most obvious, some YT videos too. As I said, the music is generally fine.

That suggests the DVBT receiver as the fault. maybe internal volume set too high causing distortion, or the internal equalizer has funny settings. Youtube also has its own volume control that can be set too high. I'd lower volume on de DVBT receiver and set internal equalizer to flat, as well as turning off any 'sound enhancements' like normalisation or stage or cinema mode or whatever.

Also, youtube and DVB-T broadcasts often have an awful sound quality by themselves, super loud and normalised. This could explain your problems as well.

Good choice on the electrolytics. That makes a cause in the filters very unlikely.
