i have 2 HM75s in my Laney cab, and i liked them so much that when i was putting new speakers in my Marshall 800 cab i got 2 more WGS speakers, this time Retro 30s. found a pair of Celestion G12t75s on the bay for a good price and snatched them up. i cant comment on those, because they are in the 2 bottom positions, but the Retros are on top and man are they AWESOME. straight out of the box they sounded amazing, nice deep low end, great midrange, present and not too peaky, and the top end is smooth and really articulate. the HM75s are a lot like G12t75s, except they seem to have a tad more midrange to them and a smoother top end. i love them both, but i think the nod MIGHT go to the Retro 30s, just for the extra midrange aggressiveness. but so far i like them both a lot. i read about them on another site, and figured why not? for half the price of new Celestions, and they even sound better IMO. not to mention if the speakers dont work for you you can send them back and exchange them (one time, but still!)
IMO its a win-win situation. great price, american company (even if the parts are made overseas), and you can exchange them if they dont work for you. oh, and shipping is FAST. i ordered my G12T's about a week before the Retros, and the Retros were here in a day and a half. the G12s took 2 weeks. yes, it was in the description that they would take 10-14 days to ship after payment, but usually thats just to make sure payment clears. usually sellers ship before that, especially when you use paypal and pay them right away. but that dude took his time LOL
WGS will get my money for a long time. probably going to get a couple Retros for my Laney cab to replace the last G12M70 and the Peavey 1230 that are still in there. then i will have 2 amazing sounding cabs.
