I really can not recommend that bass driver. It really is just a mid range unit. You can't get F3 below 75 Hz. Also the driver has very limited throw, and handles little power below 120 Hz. So that leaves no room for diffraction step compensation, so the driver will have a thin weedy sound. So you would have to cross it over to a sub at 120 Hz at least which is far too high.

How did you get that driver, and can you return it?

This driver, will get you to 60 Hz at good power in a quarter cubic foot box or so. and down to 50 Hz in a half cubic foot enclosure. at good power.

I would only recommend your driver as a mid range unit and not a bass mid.

How big is your room and will speakers with single 5" drivers do the job?

Here are the possible bass alignments.

The SEAS driver is cheaper and has a smoother frequency response.

I already have the drivers. They are leftovers from my attempt to build a 4 way active soundstage in my car, they have been sitting in my closet for over a year... so I was wondering if I could put them to use , rather than being paperweights... I also have a pair of Dayton RS180 4 ohm that I'm not using

The room is 15' by 20', front and back have sturdy concrete walls, to the right there is the kitchen (small condo) and to the left a big glass door (12' x 8')

I don't need the speakers to play loud at all, as I can forsee neighbours complaining, just need them to sound good with a nice soundstage

I'm also planning on building a small sub based on another leftover driver, a phoenix gold rsd10 sub

What are your recommendations? - Is it worth the time and trouble to build this system, or should I just throw the drivers in the trash can and start from scratch? - Right now my system is an old bose, which is killing me

The problem with those drivers is that they have a poor bass response and poor power handling in the bass. Otherwise they are good drivers. They would make good mid range units. They would be OK in car or as computer speaker drivers, but for a room that big no way. I think they would sell on eBay.

Your intended use for them is a miss application.

How big a speaker could you handle?

I have lots of space, so driver/cabinet size is not a concern, as long as it provides a better sound experience than the smaller drivers

Two more questions. Are you planning to use a sub? What is your speaker budget?

Two more questions. Are you planning to use a sub? What is your speaker budget?

Speaker budget is around $300-$400, about $100 for crossovers and another $100 for cabinets. I would like to keep the total cost under $500

I have a phoenix gold rsd10 I could use as a sub
http://www.crutchfield.com/p_218RSD10/Phoenix-Gold-RSd10.html?tp=111&tab=features_and_specs

If that is no good, I dont mind getting another one, but it would have to be included in the speaker budget...

Also, if possible, I would like to go the diy route

Here is a design that will not break you budget. The crossover is simple.

I do not think that sub is any good for home use.

Put these speakers together first and see how you get on. I think they will be a good listen without a sub.

when it comes to a sub, I would build two subs and out the speakers on top. Second order crossover between 80 and 100 Hz will work best.

Lets see what your budget is when you have this much accomplished.

Enclosures should be made from 3/4 MDF and well braced. I strongly recommend dado joints rather than but joints. Apart from the port everything should be tightly sealed. The port should be the only opening.

You need to make the front of the cabinet as narrow as possible. The tweeter and woofer should be as close together as possible. The speakers should be on stands, with the tweeters 36" above the floor and the speakers 10 to 14 inches from room boundaries.
