Default AMT 1d replacement bass driver?

a good buddy had a bad day and lost both bass drivers in his AMT 1d speakers. He has contacted ESS and has a line on both replacement and rebuild costs but we were wondering if there is a better quality upgrade driver that could be used. Not that the AMT driver does a bad job as it can make good deep bass but it is a small inexpensively built 10 inch driver that might well be bettered for the same or less money than the factory driver. Anyone have any alternate driver experience? Thanks and have a happy Christmas. Regards Moray James.

Give this one a look Moray. I use 'em with my AMT1c's and cross fairly high 6Khz with a 6.8 uf cap in series. I wish they were more efficient as I had to trim the AMT's back with an 8 ohm 10W resistor to level things out a bit. I hated the old xover network that ESS had in the unit. IMO - get rid of that garbage - or at least upgrade the components. Parts-Express.com:*Pioneer W25GR31-51F 10" Butyl Surround Woofer | woofer 8" woofer midbass rubber surround pioneer

Oh - yeah - almost forgot - watch out for the rubber on the surround - it can get caught in the screw and get stretched.

U R Welcome Moray - and Merry Christmas to you as well Mate!

I saw these at PE and they look interesting for low cost - Parts-Express.com:*Peerless 830634 10" SLS Woofer | Peerless P830634 10" driver SLS Woofer subwoofer bass mid midbass mtm 2-way Tymphany genelec 342-6001 2-way 3-way midrange mid vifa studio monitor active

I haven't used them so I can't comment one way or the other but Peerless usually makes good stuff.

10 inch woofers that go low are and are still fast enough to match up with an AMT hard to find
