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..

Congrats on the nice job ! Love to see when a plan comes together.It makes it all worthwhile.. The wings and smaller ports should really step up the bass output on those..

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......

Depends on the local boundary conditions as to how much they help with bass loading, so for all but the largest rooms or outdoors, you primarily want them to smooth out and extend the horn's response ~ a half octave since it's a much truncated 55 Hz flare frequency. 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.

Thanks GM for the reply. Does that mean I would have to move the horn forward and if I did would that create a time alignment problem? Truncated, had to look that one up

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.
