Marten Coltrane Alto speakers

Early models had that problem, after that review Marten built the room for breaking in finished louspeakers. They also break-in raw drivers.
Lot of loudspeakers haven't been broken in and the annoying High End (ringing) is main drawback.

They break in their speaker in house for 3 days and ship them to distributors/dealers.

I never said they need 6/12 months of break-in.

Samuel33 you should know the facts before you put your hands and keyboard in motion.

To Samuel33,

Marten is the firm Coltrane is their famous model. And this thread is about Coltrane Alto model.
They play speakers 72hours at max level.
Average speaker needs 200-400 hours of break-in on moderate volume. If you listen to the speakers 2 hours a day you will need 100-200 days for break in

Samuel33 based on your posts on AG forums it seems that you don't have a clue about High End. You're like 16 year old kid in daddy's Ferari tryng to get out of the crashed car not knowing what has happened.

Please do yourself a favour and buy B&O system and everyone you know will like you more.

2 Samuel33 your learning curve is steep but you know it's short way down. If you find AG forums not interesting enough try toys'r'us stores.

2 Keithr loudspeaker does have lot more parts then just the edrivers.

2KR Maybe you read to little? My ears are just fine and they get calibrated in concerts of unampilfied classical music.
Thank you for your care of my wellbeing:)
