These are my babies:

And my attempt is to upgrade them to modern standards.
I've considered maybe running 1 Usher and then the other half a boomy-er deeper 6.5 sub but the truth is they kinda hit hard(maybe not 20's) without a true subby woofer now. And also I have been warned that mixing and not pairing up in a box like this is not recommended and I'm heeding that warning.
I am however open to replacing the front passive for a sub....and maybe port holes out back?....but I am hesitant to open up port up front cuz I happen to love their original cosmetics. It may be possible for me to seal the bottom half from the upper half.
But really it would have to be well well worth the extra work.
It is currently a true 2 way design tuned to deliver good bass.
I'm trying to increase its lower spectrum and move it out of muddish mids/upper mids at the same time.
The original tweeters have been long gone. (prolly blown by me or my brother the 1st time out 20 years ago.)
Aside from cosmetics I have no desire to make them originals or restore them. I aim to truly upgrade/enhance their original spectrum.
Sd if I go with the Ushers(2) I will build the X-over and tweet at the same time. Except I will do each speaker seperately at seperate times.(budget)
The box is tuned for 73hz originally but depending on what driver I choose this frequency goes up or down in the software models.
With the 2 ushers I beleive it goes down to the 50's while enhancing the mid-range probably plenty crispier than ever.
As far as I know what we been talking about isn't too far off from the original design so I think the passive and the driver selections should match up damm good.(definite upgrade from the older drivers which couldn't have been purely subwoofers either)
Like you said I think the X-over is of upmost importance. Thanks for the scoop on pulling tweeters down that far. If it's common practice and the modern move then I'll go with the trend.
I'm not gonna order just yet. Let me know your thoughts.
These Ushers are as big as I can go and should drop right in perfectly. The truncated sides allow them to fit snugly side by side. I've measured cutouts and exterior flange areas. They are truly the maximum of what will fit in stock original locations.(6.5's)
I'm looking at 8845P not 8945P becuz 8845P is truncated flange.
Another factor is they truly outperform any 6.5's by a very good margin. (Or at least from partsexpress.com)
Apreciating your help.
