BanjoBill Posted January 16, 2021 Share Posted January 16, 2021 I am using a pair of 1987 oiled oak Cornwalls and they are sounding a bit thin. All of the drivers seem to be working correctly, the speakers themselves are mint as can be in terms of being cared for. Any suggestions. Should I replace the tweeter diaphragms or other actions like updating the crossovers? They don’t sound bad, they just don’t have a very full sound which I know they are very capable of. 1 Quote Link to comment Share on other sites More sharing options...

wuzzzer Posted January 16, 2021 Share Posted January 16, 2021 Are these new to you? Have you tried positioning them differently in your room? What amplification/source/etc. are you using? 1 Quote Link to comment Share on other sites More sharing options...

Let's start by reading the DCR of the woofer , midrange and tweeter , with an OhmMeter -- -select Ohms - woofers are 4Ohms , midrange 16Ohms , tweeters 8Ohms ------Please -post the results - what kind of amplifier are you using ? power specs ? - Quote Link to comment Share on other sites More sharing options...
BanjoBill Posted January 17, 2021 Author Share Posted January 17, 2021 So, the amp is a Muzishare X7 with Genelex KT88's and 12AU7 phase splitters and vintage telefunken 12AX7 preamp tube. It makes 25W in Triode mode 45W in ultra linear. I have generally used it in triode mode, but have used both. I kinda prefer the sound of the triode mode. I will check the impedance of the speakers when I have a chance. They are in a room with a concrete floor that is quite large. The room itself may play into it.. I have a pair of Linn Majik 140's with a Naim NAP-250 amp that are upstairs in a room with plaster walls and wood floors and they seem to have deeper bass and better bass control, which is to me surprising as they are a much smaller speaker. 1 Quote Link to comment Share on other sites More sharing options...

No surprise there. The room is playing a major factor in what you're (not) hearing and feeling. Quote Link to comment Share on other sites More sharing options...
