Replacement Woofer for a Yamaha NS-A2835 Tower Speaker... Woofer M/N: Yamaha 110020

Hello,

Woofer started to sound scratchy few months ago so I didn't use it as heavily. Now it has gotten worse and I finally decided to start looking to replace it.

Tower Speaker Model Number: NS-A8235
Woofer M/N: Yamaha 110020

The model number on this woofer is hard to find and I was wondering if anyone knew where I could purchase a replacement.

Thank You.
Joe

Every time this question comes up, we always say go to the manufacturer first.  That is the only way to be sure you are getting a proper replacement driver.  Using an aftermarket driver isn't as simple as matching the size and nominal impedance.  You will need to match Theile/Small parameters to make sure it has the same low end response in the cabinet.  You will also need to make sure it has the same frequency response on the woofer's upper end as well.  You will need to match distortion plots.  Finally, you will need to make sure the new driver has the same impedance plot and sensitivity as the original or you may need to re-design the crossover.  Sounds like a lot?  It is if you want to do this the correct way. 

If you want to throw an 8" driver in there, then I recommend changing out all of them so that the speakers will sound the same.  Since the speaker as a whole is 8 ohm, are the 8" drivers 4 ohms wired in series or 16 ohms wired in parallel?  Or some other combination that interacts with the crossover?  Parts Express is the site you need to check out.  Depending on the answers above, the Dayton classic series as well as the Goldwood drivers should work.  But you can get anything from generic OEM models to Vifa, Peerless and Tang Band drivers that cost more than what your original speakers retailed for.
