As the title says, quite keen on making some slim speakers "baffle width" would be about 5" ideally, obvious mid and tweeter are no problem, but finding small woofers suitable for taking over from 450hz is down is proving a problem.
There's no target bass frequency to reach but needless to say lower is better, I know 40hz is way out of reach but maybe -6dB at 55?
Any recommendations would be greatly appreciated, I know tang band make some small sub-woofer type drivers, has anyone here had any experience with them?
thanks

The Tangbands can do the job but would need some help. Best is to make these powered and add a boost for the lowest frequencies. And that means it would be best to separate the upper bass from lower bass (boosted). I`ve thought on using 4 x Monacor SP-100 with a Faital 4FE35 to take on. Something like a FAST but with many small woofers to make the cabinet as slim as possible. The Cheap trick speaker of Klang+Ton claims to be able to do -8db/65Hz with 89db at 2.83V. With 4 of these woofers (they`re cheap) you can do even more impressively.

Peerless 830870. Sims in an ML-TL give F10 near 35 Hz, 6 in the low 40s (note that F3 is meaningless except when you are talking filters).
It is quite startling to hear these when the big drums kick in.
HF response more than good enuff for a 450 Hz XO — we used a 240 Hz PLLXO (1st order).

nannoo, Desktop? Stand? Floorstanding? Close listening? Small room? Normal room? How deep?
Changing your width spec to 6" dramatically increases your front mounting options.
Mounting the woofer on a longer side panel would allow a larger driver.

Just scored the last pair of these in captivity on Aus:
http://www.wavecor.com/WF138WA02-04_specifications.pdf
They model very well on manufacturer's specs, & I've used the 6" version in studio monitors
I think there's a newer version with a different frame,
problem is finding them, Wavecor don't seem to be widely distributed

Building a few to be mounted in corners of wall for a relatively small surround sound set up - hence no open space or baffle step but will have room gain issues I expect. I deliberately side stepped stating that in the OP as I'm looking more explicitly at small drivers that can hit bass notes (there is no sub)
Hence the suggestions for 5.25 simply don't work for this application...

Looks like it could be good, I'll grab a couple and check em out in mini desktop 2-ways first to get a feel for them I expect
have you used them? How do they compare to the other SB stuff? Have worked with there NRX series mid woofers before, they were pretty nice to work with - easy to xo and great sound, but felt a little more like extended midrange drivers than 2-way beasts IYKWIM.Again, it's to go in the corner of two walls. Small cab, small volume, thus small driver is needed. I have a lot open to me in terms of full range or 2-way systems, but I'd like to at least look at what's possible with 3-way.
We're talking about a maximum driver size of about 4" here... currently it looks like trying some tang band micro subs in an active config and some SB12NRX25-4's for comparison.

Looks like the a less expensive driver similar to the Peerless 830870 i suggested. You’d need to do the sims to see if it would fir a smaller box (it has a larger Vas but a lower Qt).

+1 for the Seas. Half the price of the SS, same size frame, more Sd, and kicks like a mule. It's not great for a 2-way because the breakup is low in frequency and propagates even lower in the HD, but is perfect for a small 3-way.

I just finished testing the SB13PFC25-08. Wonderful budget midwoofer. I don't have their more expensive models but I intend to. The sound reminds me of the old Scanspeak.
I checked yesterday I think for 2 drivers in a BR it was approx 10-11 litres. Not bad
