Goldwood GW-210/8 10" OEM Woofer 8 Ohm
I am wanting to build my first sealed powered subwoofer with this speaker. What do I need to be looking for In a plate amplifier to match it and do you have any good suggestions on which to use?
I would recommend looking at the 4 ohm version of this woofer if you only plan on using one. This in 1-2 cubic feet sealed with our SA70 plate amplifier will be nice for low-medium level playback.

I have this in a 1.8 cu ft enclosure, would these put out more bass if the enclosure was ported?
The answer is that you would get more volume but you will likely sacrifice bottom end. What you really need to specify is what frequency you are hoping to augment. When you port an enclosure, all frequencies below the port tuning frequency drop off in volume substantially. For this reason, some speakers do better in ported enclosures and some better in sealed, for example. A woofer that is not designed to respond to really low frequencies is likely going to do better in a ported enclosure because porting it will give a +3db increase in volume at the frequency that the woofer was intended to do well with anyway (there's no reason to augment a frequency that the woofer is not designed to produce) and all the frequencies below the port tuning frequency will drop off, albeit faster than normal, but in a negligible manner because the speaker wasn't intended to produced those frequencies well anyway. This woofer drops off pretty fast below 40 hz. I'm not sure that you'd gain much from porting as it already has a nice bump in frequency response at 40-50hz. You could port it higher, but remember, you'll be sacrificing bottom end by doing so. If you port it below 40hz, you run the risk of over-excursing the cone. I don't think it is worth work. I'd leave it sealed, but you will "get more bass" by porting it maybe not the quality you want though.

Is the Goldwood GW-210/8 10" OEM Woofer 8 Ohm (Model: GW-210/8) a compatible replacement for the old Sony Speaker Model SS-U542AV 10" Woofer?
The speakers (Model SS-U542AV) came with the older Sony stereo system SEN-R5420.Thanks
Unfortunately, we do not have a cross-reference by brand, model, or anything of the sort. If this Goldwood speaker's size and impedance are a good match for your sealed Sony cabinet, it should be a good performer. If the cabinet is ported, I generally recommend the Dayton Classic woofer, linked below for your convenience. If you require further assistance in making a choice, please give us a call at 1-800-338-0531, and we'd be glad to discuss the options with you.
