Just a couple watts will get them screaming..When they were designed there wasn't a whole lot of 100-200 watt per channel SS amps..It was mostly flea powered tube amps..Quote:

Kudos! nice job!
Wow--great job on your restoration! I'll be interested to hear your impressions of them after you reduce the port size and/or add the wings--I think even just reducing the port size will really beef up the bass.....
Wings should be full hight and about 10~12" wide, IIRC. Closing up the port will help the bass. Mine are currently at about 100" sq, but I'm closing them down to around 76" sq as that seems to work best for my set up. YMMV, of course.
Are my eyes playing tricks or is those dust caps all pushed in ?
Yes they are can they be replaced with out a recone?
Yes, Bill at GPA can sell you brand new dust caps for your woofers and you can replace them without doing a recone. If there's nothing wrong with the cones and voice coils there's no need to recone them......Quote:

Ideally you want to use the top baffles also as they will still audibly help even if there's a gasket-ed cutout for the HF horn.Quote:

FWIW I'm betting you'll like the bass more the way you have them as opposed to smaller ports. That orange was god awful!!! I bet they rocked pretty good with the ol Marantz. Those have pretty good bass.
