Just to add my own 2p, I've used a Marshall SE100 (actually a Groove Tubes unit built by GT for Marshall) with my 30w Laney and originally kept the HH Invader speaker which iirc was 75w.

As above, attenuating the volume only didn't bring the amp alive as I'd hoped, as the speaker just wasn't being pushed to move any air.

I then swapped the HH for a Celestion greenback 25w and there was the tone. I was still able to play at a good level though which helped, not super quiet.

One caveat, I only play at home so swapping the speaker for me was fine. If you gig the amp you might want to consider a 2nd cab for home use, with the attenuator and lower rated speaker.

The Greenback is one of the most respected of guitar speakers. Not sure about the HH Invader but I think they were made by Fane? Not a name that inspires much joy in guitar player circles? So I am not surprised you "found your sound!"

Though rated at 25W Greenbacks are tough buggers and even more conservatively rated that most Celestions.

Not sure Dave but Laney bought HH years back hence their continued use in Laney products. Ceramic magnet I think, which also adds a certain edge to the tone.

It certainly has a well known and respected tone/eq curve so probably did help my cloth ears more than the HH!

HH switched to making their own speakers years ago. I'm led to believe the older ones weren't great but the current ones seem OK, if not quite top-shelf.

Yes, well I have been told that guitar speaker industry is pretty incestuous! Unless it has a famous name on the magnet you really cannot know the maker.

Ceramic magnet? Isn't everything at this price point?

I dunno, the Fane's in my MM120 were killer. I'll never forgive myself for letting that one go

Take my advice, I'm not using it.

Gor the UK, a lot of the cones are all made in High Wycombe to the speaker manufacturer's requirements then get shipped off to be installed in the chassis.

I understand that some of the 60s and 70s Fanes are highly sought after. I've got a late 60s/early 70s Simms Watts head with a matching 4x12 cab with Fanes, which a number of my mates regularly ask if I want to sell. At present, I don't. It does sound OK, though.

Back in the day ('60s, '70s) Fanes were a (relatively) budget option, EV, JBL and, especially, Celestion were the sought after speakers.

I don't think the "purple frame" 50 watt Fanes used in the vintage Hiwatt 4X12 cabs were ever thought of as budget options, Sam. They were differently voiced to the Celestion offerings, with more clean headroom. I remember being presented with a hired 100 watt Hiwatt stack for a charity concert I did in 1970 (ish) and it permanently rearranged most of my internal organs while I tried to get it to overdrive !

I don't think the "purple edge" 50 watt Fanes utilized in the vintage Hiwatt 4X12 taxis were ever thought of as spending alternatives, Sam. They were distinctively voiced to the Celestion contributions, with all the more spotless headroom. I was given a procured 100 watt Hiwatt stack for a philanthropy show I did in 1970 (ish) and it forever revamped the greater part of my interior organs while I endeavored to get it to overdrive !

Respects, John
