Replacement woofers for Optimus LX-PRO55
I am trying to determine the best speaker to replace the Optimus LX-PRO55 woofers. I have determined that several speakers might be "drop in" replacements: GRS-8, Goldwood GW-205/4S, and Dayton Audio models DC-130AS-8 and DC-130A-8. I do not need the shielding feature of the original. To me, that makes the DC-130A-8's parameters seem better than the DC-130AS-8. The Goldwood and GRS have better power ratings, but inferior frequency responses. I will be replacing the passive crossover with an active crossover and will be bi-amping by adding speaker terminals for the additional amp. Sound deading spray will be used on the baffle and interior of the aluminum cabinet. Polyfill will be used along with foam in seams. Does any one have an idea of which speaker will be best suited for my project. I have been using these speakers with an AR S10HO sub. I detected a buzzing noise from one of the LX55's and noticed a portion of the foam surround had cracked.
The original speakers from Radio Shack, or actually Allied Radio Shack were mostly oems by eminence or cts. Neither made a speaker better than the Dayton Audio DC 130A. You are correct you do not need the shielding.

Replacement for factory Bose acoustimass drivers?
Any idea if these would work as replacements for the drivers in the Bose acoustimass series? (Particularly AM-5)
Yeah, these will work. However, I can't find TS specs for the original Bose woofer, so I can't confirm how well it will work. Measure the DC resistance of the woofer and check the woofer selection guide to find one with closest DC resistance, the best low frequency extension, and the closest physical dimensions. I believe the AM5 bass modules have a volume of roughly 0.6 cubic feet and have 2 woofers. So if you can, find woofers with a Vas of about 0.25-0.4 cubic feet.It's also worth noting that the original woofer had a 3 hole bolting pattern, and pretty much any substitute you find will have four holes and thus will not line up with the original mounting holes.Your surest bet would really be to try and find an original Bose part if you want to stick with the Acoustimass setup, however P-E won't have these. They pop up on auction sites and audio trading and sales forums sometimes, so you may want to investigate those.

Can the shield be removed from this woofer?
I trust Dayton does not intend anyone to remove the shield from this speaker, but is it possible (even presuming it would void the warranty)? I ask because I want to use these in the Minimus 77 and would like to avoid reducing the usable cabinet volume more than necessary. Thanks in advance for any guidance.
Typically the shielded magnet surround of a speaker is only a few mills thick and is very tight to the actual magnet. The Dayton Audio DC130AS-8 5-1/4" Classic Shielded Woofer is no different. I understand your concern at not losing cabinet volume but I don;t think you would gain much in volume by removing the shields.Perhaps an alternate speaker would be a better choice in your application, or simply consider doing some design work an adding a tuned port to compensate.Good Luck
