Austin speaker works kt-70

I have a Austin speaker works kt-70 in a closed back cab. I use it with a 25 watt blackface style amp (phaez corona). I love the amp and cab. I also have an orange closed back cab with a vintage 30 in it. Never bonded with this cab. I originally bought it for use with a tiny terror, which I sold. That seemed like a good match.

So here is the question. I am going to buy a TA-15. I am thinking of ditching the orange cab to help pay for the amp. But how will the TA-15 play with the KT-70? Is the orange cab a better match?

As a side note...I don't gig.

Thanks

From what I have heard of these speakers they are very versatile. I've read a post where somebody wrote that, "it's the first cab that they heard that sounds good with every head" or something to that effect. If you have the cash up front, buy the head and if it doesn't sound good with the orange cab, sell it and recoup the money.
