Ampeg flatback or NV610
 

About to pull the trigger on a flatback which needs restoration.
Ihad a flatback back in the 80s which I also restored( lotta work). but really liked it.
Before I commit to the project thought I'd check in an get some opinions.
2 drivers have shall hole in their surround. Can I fix that or do I need to recone them?
I also have access to a 78 tilt back cab with original eminence drivers all good for about $100 less. This would require cosmetic restoration as well/ Are the CTS drivers SIGNIFICANTLY better tonewise?
Finally, I have heard that the Bergantino NV610 sounds like the old flatbacks with the CTS. Has anyone actually A?B evaluated them side by side to form an opinion?

Wondering if I should just wait in the weeds for a bergantino to come along or invest the work and cash to bring this flatback back to life.

All input welcome

Neglected to mention that I would not have a chance to listen to the cabs. both are far away.

I would narrow the choice down to the flat back and the Bergantino.

Size and weight and portability are big issues, but if you are talking tone alone it's a tough call. I've played both but never side to side.

Just because you get a very similar tone with the Bergantino but can put more power through it without worrying it would be my choice. The flat hacks require some caution if used alone with a cranked SVT.

I've got both but only recently and haven't done a proper A/B.

You wanna drive in one day? Maybe I can talk the studio guy into letting us do a comparison in their big room. My basement is hardly ideal.

I'd love to hear your impressions if you do this.
