Which Neo15 for Trace Elliot 1153

[The fasting showman]

Hello,
Due to us becoming a one car family I've had to sell my Marshall VBC 412, my only cab now is a Trace Elliot 1153. If money wasn't an option I'd ideally get a Barefaced Compact, with this in mind I'm mulling over replacing the stock Celestion with an Eminence 3015. Or...given that my amps are GK800rb and old 400rb ,a 4 ohm speaker could be better, perhaps. So the Faital PR15-400 4 ohm is another contender.

I don't have access to a decent PC or WIN isd so I'm pretty clueless as to what would be best, it's the deeper version 1153, the later one.

My sound is more of a low mid gritty P-bass sound with not a lot going on underneath 100hz really. I just don't want to make an expensive mistake with neo speakers in this price bracket.
I'd be grateful for any advice or insight anybody can offer.
Many thanks.
