Hey guys - lots of great discussion!
We have copies of two different JJP factory cabinet speakers and are aware of a third. These are the GRS 8PR-8 and the Pyramid WX85X, both made in China (as is the Goldwood GW-8024 we supply).
There are two ways to express power when discussing audio - "Peak" and "RMS". Peak is instantaneous power for practical purposes, and RMS is sort of an average based on a sine wave which approximates audio. When you see a power rating of 300W on that speaker I can assure you that is not RMS (it is a gimmick). The 8PR-8 is rated to 65WRMS, and the GW-8024 / WX85X are rated to 100WRMS. All technically have adequate power capability, but the 8PR-8 will bottom out (reach max excursion) with our amp whereas the other two are fine.
All three have a 1.5" diameter voice coil.
We've obviously listened to each and chose the GW-8024 because it sounds better. Mostly in the heavy percussion when the ball is bouncing in the jets, but other places too. Also, we know of the poor performing 8PR-8 so we need to ensure that everyone gets what's needed. Feel free to compare, but I'd urge you to utilize the GW-8024 we provide. I can't say that everyone will hear a difference but I am certain there is one, and we've received this feedback from others.
Below is a table of the weights for each speaker which is almost entirely driven by the magnet size:
GW-8024 - 3lb 2.2oz
WX85X - 2lb 10.5oz (-7.7oz compared to the GW-8024)
8PR-8 - 2lb 12.0oz (-6.2oz compared to the GW-8024)
The Pyramid has a large vent opening which likely explains some of the difference of 7.7oz compared to the GW-8024. All use ceramic magnet material so it does make one wonder how much has been "hollowed" out as part of that companies' cost reduction. There is a cliff where the magnet size does become important if not vital - I'll keep a heavier magnet in play any day of the week.
The image below shows the three side by side.
Thanks for your attention!
