I happened to look on Marketplace as I do sometimes to upgrade some Klipsch R-15M bookshelf speakers. I don't have hundreds to upgrade so I usually just peruse and then sign off, rinse and repeat every few months when the urge strikes.. Well this time I see a photo of a single Penta speaker, $150. Doesn't have the make or model in the description just "tower speakers 2, $150". I'll be honest... I had never even heard of Bang & Olufsen until then.. But after digging around it seemed that this might be something to go after. And so, after she haggled herself down to $100, I am the proud owner of a set of Beolab Penta I speakers (6603)! So, between when I made first contact and picking them up, which was a few days, I did my research. Understood I was going to have foam rot. Looks like there is some recapping that could be potentially useful too. Taking them home, I have confirmed I have what I'd consider based on the minimal research I've been able to do that I have pretty decent rot going on.. I plugged them in long enough to know then work and produce sound, but that's about it. I am NOT an audiophile.. I'd say I know more than the layman on speakers, but not by a whole lot. It seemed like the mid speakers weren't doing a whole lot. The sound wasn't BAD, but they didn't seem to be vibrating at all. Is that normal? Is it because of the foam rot? So here is where I am at: I am planning on buying new foam surrounds from a decent place? Any place that sells in the US? I typically repair old video game consoles so I am quite comfortable with soldering. I have never repaired speakers before but after watching some youtube videos, I think it is in my wheelhouse... Between the two sites I'm probably looking at around $120 USD, which still isn't bad... Any other tips or suggestions? Thanks in advance!!
