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.
You're going get significantly deeper bass just on account of the lower volume resonance of the larger cabinet. It's entirely possible to dig down into the low 40's with a single 6.5" in a big cabinet. It's practically impossible in a bookshelf. 
Thank you. That makes sense. I was looking for bookshelf to keep the cost down but in truth, for this application, a tower would be easier to position. So with that and the advantage of better bass the $100 might be worth it.
I answered you a moment ago in your earlier thread, n80. The bookshelf really never keeps the cost down, because you have to add stands to get an equivalent sound. Or, put them on shelves, etc, and ignore the difference. It's not just better bass, either. Everything is improved, or usually so, when the drivers are up at a proper height and away from the walls (or books). :)
Not sure what speaker you are looking for but there is a set of new Klipsch RF 62 II on A’gon for $650 free shipping they have dual 6.5 woofers and at 97db will not take very many watts to get them loud not sure about SQ. 
For his purpose, he does not need to spend that much. Enjoy ! MrD.
Didn't see a $$ limit I thought $650 was pretty good for towers with dual 6.5 woofers.
djones, that’s my fault. This is sort of a duplicate thread. I mentioned my budget in the other thread. I’m looking for something in the $350 range but we all know how that goes. Max would be $500. The ones you mention would be great but I'd end up in hot water.

Klipsch has a new tower with a single 6.5 and a 1" tweeter. $500 new, free shipping.

Polk has a dual 5.5" woofer with tweeter for around $400 new, also free shipping.

This is strictly low end. No long serious listening sessions. Casual listening and background music for the room. Only looking to better my existing 28 year old Bose 2.2 bookshelfs.
Oh, useful info....these will be driven with an old Toshiba receiver that only puts out 25 wpc. For now anyway.
Didn't see that as Rosanne Roseannadanna would say , " nevermind". 
Sucks getting old, it just goes to show ya , it's always something. 
Well, when you mentioned "Rosanne Rosannadanna" I knew exactly what you meant and I would have sworn that was the character that did that skit. I didn't realize it was "Emily Litella" until I looked up the video. 

Gosh, Gilda was a funny woman. They don't make them like her anymore. 
Hey @n80 - There are some good deals on speakers, especially Boston, at right now. They had a smallish Boston floor stander for something like $169 each, but the second one is BOGO 1/2 off right now. They also have KEF, Canton and a couple of other brands. Worth looking into for your cabin speaker replacement needs.
If you are ok with used speakers why not do a zip code search on eBay and Craigslist using the generic term " Speakers " and see what you find ,you could also create threads on any forums you belong to where you give out your zip code or city and ask members if they have any unused speakers they'd be willing to part with for your budgeted price range .

A year or 2 ago I saw a thread on the Emotiva forums by a kid trying to find a reasonably priced DAC for $100 or less ,he lived in my state so I posted that I would GIVE him an unused Emotiva DAC ,when he showed up to pick up his free DAC he asked if I would show him my system as he had never seen an entire McIntosh system ,so I showed him & spent a few minutes talking to him ,found out he was a nice kid ,when we went into my garage to get the DAC out of the attic I used the beat up Klipsch Lascalas in my garage as a step stool & he mentioned how he would love to one day own a pair of Lascalas ,damn things we're in my way so I gave them to him too ,he came back the following weekend with a friend and a truck & got those things out of my way ,they were cosmetically beat down but mechanically sound , I think you'll find there are alot of us with extra gear laying around ,stuffed in closets and attics or garages that's cosmetically not fit to sell but is light years above what you can buy new , just yesterday on the Emotiva forums a member gave away 3 sets of quality cans he had laying around ,I'm not a headphone kinda guy so I didn't take a pair but 3 other members did ,don't be in a rush ,$350 is still alot of money ,do some searches and post some threads ,after all your not asking for charity ,you have money to spend .
I donated a pair of NHT super zero's to goodwill when I downsized to a patio home earlier this year. Never can tell what you might find there thinking about giving them my old pioneer dvd/ cd player I never use anymore. 
djones51 a friend of mine here in Agon found a McIntosh Pre/Pro at his local Goodwill for $300 with factory packing ,I hesitate to post his name because he flipped it for $1,200 and I know some people hate gear resellers .

Your post made me remember something very unexpected a member of Audioholics did for me ,his username is WMAX and he's some sort of audio engineer and is of the mind all amps sound the same ,seeing pictures of my McIntosh system with 4 McIntosh amps triamping my fronts he sent me a pair of Behringer A-500 pro amps that cost $199 each ,the amps are 100wpc @8ohms and 500wpc @8ohms bridged mono ,he wanted me to do a real time A/B test against my pair of McIntosh Mc-252s being ran as 500 watt monoblocks powering my mids , I did the test switching amps on the fly and didn't really hear any difference below 10 watts ,above 10 watts night & day , when I finished he told me to keep the amps as a gift ,I can also remember when the owner of Audio Salon bought a McIntosh Mc-7104 I had been wanting for my Home Theater and just sent it to me with a note saying " pay me when you can " ,there's some great people in our hobby for sure .
I did a zip code eBay search just for 'stereo speakers'. Got 23 hits. All but two were Bose speakers. Not just from one place. Weird.
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.
I believe Elac makes some nice speakers in your price range.

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.
