Tower vs Similar Bookshelf?


I asked this question in an unrelated thread but did not get an answer so I'm going to see what kind of input I get by posting as a separate thread:

I'm looking at lower end speakers for my cabin.

I was looking at a certain brand and noticed their lowest end small tower speaker had a 6.5" woofer and 1" tweeter. These were the same woofer  and  tweeter that come in one of their bookshelf speakers. The towers cost about $100-$150 more than the bookshelf version. Both have bass ports in the the rear.

My question is: Is there any sonic benefit over the tower model verses the bookshelf model with essentially the same hardware? Better bass? Different crossover? Any thoughts appreciated.

More searching and these two are available locally:

Klipsch Synergy F-2 Black tower speakers $200 local pick up.

Polk Audio T90e Euro floor standing towers $200 local pick up.

Both sets look to be in good shape. Close by. Both look like low end speakers in terms of styling. But I'm sure both would probably sound better than the Bose 2.2s I have.
You mentioned rear ports.  Keep in mind that rear ports usually have to stay a couple of feet away from the rear wall or they get boomy.  If it's truly a cabin and not a home you won't have room for this.  Go sealed or front ports...
Good points.

The little Bose that I have a front ported. One of the Klipsch bookshelves I've looked at have a front port. The tower cited above has a front port. The Polk Audio tower has a bottom omnidirectional port so any of those would do.

However, I've actually messed with positioning the Bose and to be honest, for a cabin and being driven by an almost 40 year old receiver they don't sound all that bad. I'm probably going to stick with them for now.
Silverline Preludes are a great sounding example of a small tower replicating what is good about mini monitors, with the added benefit of a much fuller range. Get a used pair.
