Beovox P45 Replacement Woofer

5 replies
I read a discussion that was several years indicating that it is hard to get a replacement woofer for the P45 Speaker. My tweeter and filler sound really good, but no sound from the woofers. I took out a woofer and did a battery test you can hear sound but no woofer movement. It's strange all 4 woofers look good but none work. So I'm thinking of taking the woofers to a speaker repair shop, they want $55 USD to realign each magnet. Total price over $200! Which is way more that I want to spend. I just sold an excellent condition pair of S60's for $260.  But I did find on Parts Express a woofer that seems to be a near perfect fit. GRS 5PF-8 5-1/4" Paper Cone Foam Surround Woofer. It's on sale for $11 total cost for 4 woofers including shipping about $50.  Of course I prefer keeping things original but $50 vs $220 is a huge price difference. I'm actually going to use the P45 with a subwoofer, so would it really make a difference keeping things original sound wise?
It's not difficult to find a woofer that will fit physically. Finding one with the same T/S parameters, on the other hand, is impossible. (Keep in mind this is in effect a woofer in a midrange size). The original woofer was custom produced for this speaker. A similar looking one was used in a larger Beovox model, but they are far from identical parameter-wise. I would repair the original woofers. Perhaps you can do it yourself. There are threads here in the forum showing how to do the S45 woofer, which suffer from the same issue. Same goes for the speaker used in the slim 1970s Beolit portable radios. Martin
Hi Dillen, Thank you for your kind response. The repair shop also said if the coils needed work, that would be another $85 per woofer for a total of :$560!  I ended up getting some Dayton Classic Woofers that fit after I used a dremel to widen the recess opening in the baffles just a tiny bit. I hope this doesn't stumble you... But they did sound a lot better with working woofers. After I used my Wiim Room/Speaker correction they sound even better. I did save the original woofers - just in case one day I will try to fix them. ps: I bought Caps from Danish Sound Parts last year for my MC120 and it really made the treble come to life!
If you still have the original drivers…

Thank you Matador for the Link. I still have the drivers, but I'm not sure I have the skill you have. But your Beolab 8000 wood frets did encourage me some time ago to do the same to my Beolab 8000's and they look great! Thank you!
