Rogers AB3a clone for the ls3/5a
Hi! Got a vintage Rogers LS3/5a in transit, I’ve heard this speaker before and they have excellent mids but are lacking in the critical 60-80hz bass region for kick drums.
Came across the Rogers Ab3 and I don’t think the price tag is justified ($4000++ WTF).
ROGERS AB3A
I do like the idea of of a bass unit that can also serve as the stand of the LS3/5a since my space is quite limited but due to the size of the driver it can accommodate it would be a stretch to call it a subwoofer. That is okay though since I would just like to hear a proper kick drum and don’t feel the need for subterranean lows nor high spl since the Rogers are not amenable to being driven to deafening levels.
So. How do we clone the AB3a? Do I wire the woofers in Parallel or Series?
Seems doable as I plan to make a passive version with and just have a minidsp and a Plinius SS amp to drive them. I can probably track the B110 woofers via ebay and have a carpenter build out the sealed cabinets.
But it says on the Rogers site that it’s a “special” doped version of the b110 woofer (doubt it) to give it bass.
So my question is: with the AB3a dimensions (H 23.62” x W7.48” x D6.5”) would I be better off just using a more modern woofer in a sealed enclosure or should I just stick to using two pairs of B110 woofers like the ab3a.
Any driver or build suggestions? Would want to maintain the dimensions for aesthetics and space and the thin wall sealed construction of the AB3a
Thanks!
PS: Also aware that the plans for the AB1 passive (the ported one woofer predecessor of the AB3a) are floating in the internet and that is also an option, but I think I will have better luck with a sealed implementation to integrate it better to the LS3/5a for when I want to listen to rock music.
