OO1 Posted January 11, 2021 Share Posted January 11, 2021 26 minutes ago, Msuwendy said: Roger that, thanks again ill get back to you The issue would seem to be the Impedance setting on the amplifier -- the amplifier is seeing the speakers as setup on the wrong impedance setting - is the amp impedance setting at 8 Ohms or 4 Ohms - if 8 Ohms , the amplifier sees the speakers T500 as 4 Ohms speakers - For optimal efficiency you would need to switch the Chinese Amplifier to 4 Ohms with the Tangent T500 - Quote Link to comment Share on other sites More sharing options...

MicroMara Posted January 11, 2021 Share Posted January 11, 2021 The T 500 is a 8 Ohm Speaker so requires the 8 Ohm Tubeamp outputs as well. The minimum power requirements are 20wpc . The chinese Tubeamp ( Reisong ? ) hasn´t enough power. If it´s one of those Reisong entry models for approx. $ 300 , sorry to tell you, those are limited to 3 wpc. only. Sell it , if possible and look for another better and more powerful tubeamp. 1 Quote Link to comment Share on other sites More sharing options...

Good call but, if you post @micromara post in entirety, another story. Thanks... 1 Quote Link to comment Share on other sites More sharing options...

Alexander Posted January 11, 2021 Share Posted January 11, 2021 1 hour ago, MicroMara said: X-over T 500 This xover looks to be an exact clone of my 2nd xover build. It was for a set of T5000s and to go through such detail as to use 16ga buss wire for the common negative “spine” down the middle. The Solen paralleled 1.0 & .22 uF caps for the mids and even the same wrong (backward) wiring of the tweeter wires. I am flattered for someone to copy it so accurately. :wink: 1 Quote Link to comment Share on other sites More sharing options...

Thanks for the detail given, its got 97db with 20watt minimum, ive tried 8ohm to my T4000 the last gen of the Tangent its loud i mean real loud, but not with my old T500 which is weird 1 Quote Link to comment Share on other sites More sharing options...
