I have a set of backhorns (front ported) that I made a few years ago, for a Fostex 108s (4"er) The cabinet design was from someone in the northwest U.S., but I have lost the site info. They've been in a second system in the living room, but are now going to my son's place - a fairly small house. Of course, they've never had much LF oomph, so I'd like to give them a boost. I'm thinking a separate LF driver in a box (sealed, if possible, OK vented too). I'd actively cross it around 2-300Hz to take some load off the little driver. Not looking for movie level bass, just good for music. Anyone done this, or have any suggestions?

No reason you can't buy or build a powered sub and mate with your back horns. Were you planning to buy or build?
Thanks for the reply,
Could do that, but I've got plenty of amps, so I don't need a powered sub. I've also got the preamp set up so that I can easily do an active crossover in the pre.
The other reason for not just going for a sub, is that I'd like to cross higher than usual. So I figure it's best to have stereo woofers, located next to the speakers. And, I want something that does the low mids well. I'm thinking that this essentially amounts to a two way speaker. I don't need to go too low. Extension to about 50Hz or so should be plenty. Could always add a mono sub for more boost down low.
Was planning to build. I figured that this is not so typical that there'd be an off the shelf solution.

I'm sure those would sound nice, but that's a project of a completely different dimension. I already have the backhorn cabinets. All I'm looking to do is build a supplementary bass system. And it's gotta be fairly compact and work close to the wall. I realize there are inherent compromises in this, but I'm not shooting for the ultimate here - just pleasing reasonably balanced sound for music.
Let me rephrase: Can anyone recommend a modestly priced driver in the 7-8" range, that would give decent performance from around 50-250Hz, in a 10-15L sealed box?

What constitutes a "modest" price?
This one works like crazy in very small boxes ( I have a pair of them running right now in a HT rig):
Creative Sound - Product Details
But $100 each might be a bit steep for this application,
budget options range from
Goldwood GW406D (PE sale @ $11)
Madisound:
Aurasound NS8-385 (Madisound for $20)
Silver Flute WR17R (Madisound approx $35)
Vifa PL18 ($60)
I've not tried any of the budget models above but have personally had very good experience with Fostex FW woofers ( a now long since discontinued model FW227), but the appropriate candidates for your application range from $90 to $200 ea
The only issue with many of these smaller diameter woofers is sensitivity of probably 3-4dB lower than the FE108S, so you'll likely need at least 60-70W PC to provide adequate matching
No doubt there could be other suggestions from the class
Bueller?
Thanks Chris, that's where I'm heading with this. I'll check these out and play with Winsd. Sensitivity is not a problem. I'll use a separate amp - I have too many as it is anyway. I even have the makings of a crossover from already in the preamp. A few component changes, and added pots for level setting, is all I will need to do.
