Las compre y las acople a un amplificador Cambridge el S-61. Luego sume las medias de 5 pulgadas de esta misma marca. QUiero decir con esto que el resultado est a la altura de lo que entrega un Cambridge S-61. El subwoofer Polk 10 pulgadas se queda fuera de rango en calidad, es un problema que tengo a resolver ya que su corte ms bajo es 80 HZ. Y estas bocinas llegan a 20 HZ. Las cajas digamos que son improvisadas son cajas para JBL 10 pulgadas, as considero que hay algo que se pierde por ah, pero es aceptable. Llevo 1 ano con estas bocinas y en mi caso, repito mi caso llegue a mi top de escucha.

Just what I needed thanks

For the money it is a great replacement woofer for my home theater powered sub it's a paradigm sub although comparable nothing beats the paradigm woofer

Had to modify the cabinet. Sounds great!

Replaced a KLH 150 rms old school powered home subwoofer that I've had for about 20 years, and was very surprised at the frequency response. Friend of mine told me about the sub. So I had already heard it before I bought it.

I needed a sub woofer speaker to replace the one in my unit. I was unable to find one with the same shape mounting flange and gambled that I would be able to alter the cabinet and use this one. I was able to reshape the mounting area and although a very close fit, I was able to get enough surface area for the mounting screws. Only reason for only four stars in Easy to install was due to having to take time to remodel and the possible chance of ruining my Boston Accoustic sub woofer cabinet. Not Goldwood's fault, everyone's for not making a similar flange.Once all of that was done and it was fired up it sounded great. No buzz or vibration and I'm not positive, but I believe it actually sounds better than the original Boston Accoustics speaker. Very pleased with the outcome: great price, quick delivery and successful remodeling.

A Solid speaker! Thanks!!

I bought a subwoofer from you and the woofer blew a couple of weeks after so I replaced it with that subwoofer

I enjoy the deep bass

Fit in the rear deck of my 2008 Lexus gs350. Much better then stock!

I have the 10 and 12 Goodwood woofers. I install the 10 in a set speakers I made for home use. The woofers look well made, Install them bass was kinda soft at 1st it took about a week and now are coming alive really smooth not boom boom like you here in people's cars. I'm not looking for heavy bass that over powers the music but blinds with the music. If you have music with heavy notes they will handle it, very will well. If your building new speakers with crossovers give them time to break in. I have the 8ohms sets I posted few pics.Update - added the 12 woofers to the cabinets sides. Wow really great sounding speakers. 12 is wired directly to the binding posts. And the rest of the drivers is hook to the crossovers. speaker's packing/insulation plays a big roll in shapping the lower bass notes. Really please the way these turn out.

I've been testing out inexpensive speaker equipment with my home made amplifiers for the last two years and with the addition of these subs, my system is now entirely goldwood speakers and subwoofers. Their HDS kevlar ceiling sub has never rattled apart, so I have two of those as well. They're the most reliable brand, with no frills design, high sensitivities, and to date, not a single burnt driver in my speaker graveyard. Goldwood reports and performs accurately to specifications. This model jives well with the TDA8954TH chip, but be aware that this amplifier chip is designed for 8-ohm impedance only when in BTL, which is the only configuration that delivers the desired 420W per channel to run this subwoofer. The chip is compatible with lower impedance in stereo mode which may be confusing if the board runs two chips in mono-BTL to create an overall stereo, 2 channel, amplifier board..
