Goldwood GW-8PC-4 8" Heavy Duty Woofer 4 Ohm
I require the outside diameter to be exactly 8 inch's. Is the "Goldwood GW-8PC-4 8" Heavy Duty Woofer 4 Ohm" exactly 8 inch's outside diameter? Fitting Boston Acoustics T1030 woofers.
Yes these have a diameter of exactly 8".

Is this driver optimized for sealed or ported. I'm about to build a enclosure for them and am going back and forth sealed of ported. I would build it to your recommendations and tune it to 44hz. I have a minidsp so I can send them any signal at any slope.
This will work well in either type but you will get more useful bottom end in a ported enclosure.

Expected performance from 2 of these connected in series for a 8 ohm load in a MTM 42" tall tower with 275-070 tweeter and 260-142 crossover? The tower will be divided at about 34" so the woofers can get their own 2 ft3 compartment with 2"x2" round port.
Unfortunately we cannot say how the speaker as a whole will sound, but the box and port configuration looks good for a pair of those. You will have an F3 of 44 Hz and a tuning frequency of 33 Hz.

I'm looking to replace the warn out woofer in my Allison CD7 speakers. After 30 years the 8" rubber cone is cracked. I believe specs are 4 ohm. What are suitable replacements? I'm looking at GW-8PC-30-4. What's your advice?
This might be a good option. The main thing to check would be the actual driver dimensions. There is some variation on speaker frames so the outside diameter and cutout is important

Woofer Selection & Performance
Hi, i am looking for some guidance here before making the purchase. I am replacing a woofer driver for a studio set-up wich i use for DJing. The unit is a yamaha HS10w. The sub is rated at 150w Dynamic power (so about 75rms) @ 4ohms. Overall frequency is 30Hz-180Hz (-10db).I wanted to use the Goldwood GW-8PC-4 8" as it appears to have more balls and could probably handle the deep-mid baselines without getting flooged out as the OEM driver struggled.Is that a good selction for the unit? Will the amp be able to power the speaker given that it is rated at a lesseer RMS that the speaker itself.
This driver would probably work OK for the application although you may want to look into the Dayton Classic 8" subwoofer which is ideal for the enclosure you have and has more excursion capabilities for higher output potiential.

I am considering putting two of these in one box,I intend to double the volume of one for volume.I"m having trouble determing port size. Any help woul
In theory, if a single driver calls for a specific box size and port then two drivers would be doubled with 2 ports to make a bass reflex or vented speaker.But first understand what the difference is between sealed and ported is. A sealed box presents the speakers frequency as It's design dictates. The sound is tight in characteristic, meaning a solid transient responce. A kick drum will have a good thud as well as low pitch. An explosions will have some felt concussion because it is tight air movement.A reflex or vented box, depending on the port tuning will enhance a narrow band of low frequencies making them louder and appear sonically stronger at the expense of some loss in tightness. There is some subjectivity over preferences here. In audio reproduction each has their place. In my band, subs are ported bass reflex double 18", but my home system is sealed 12" and very tight.You have a unique opportunity to design what you want. I would consider the two subs with an internal baffle divider and only one tuned port. This couldgive you both characteristics to some degree and if desired a second port could be added later.A port can also cause a subtle air velocity noise but I have never found it to be a big problem. Dont be afraid to experiment and have fun.
