Default New toys but not sure what to do with them

Hey Fellas,

I recently traded some labour with a friend for his Hybrid Audio Technologies Legatia 4" drivers.

Now, these are primarily Automotive drivers. But they have a massive bandwidth. They claim a solid 160 to 16k. I know a few people in the car audio industry who will even forego the use of a tweeter when using these drivers due to their high end reproduction.

I don't really have any use for these little lovelies in my car at the moment since I already have that built. Instead I'd love to find a use for them in my house. I will eventually be using a 25w per channel SIPP tube amp I'm building with a friend on these. We're assembling the powersupply this week. Until that is finished however I will be running them on a small 3-4 watt single ended tube amp.

I listen to a lot of electronic music, including Glitch and Drum & Bass. But I also like my Janis Joplin too, not to describe my musical tastes as an ecclectic mess though . Rest assured I'm not expecting BASS for my techno, but if I can salvage any midbass that would be nice.

I'm looking for a jumping off point, something to work with because I don't really have a lot of knowledge on interpreting T/S parameters.

Overall Diameter φ118 mm (4.65-inch)

Recommended Minimum Crossover Frequency 160 Hz at 24 dB/octave highpass
Pnom Rated Power Input (No Crossover) 30 watts (AES Standard)
Pmax Rated Power Input (No Crossover) 60 watts (AES Standard)
Pmax (With Recommended Minimum Crossover) 150 watts
Frequency Range 90 Hz - 17,000 Hz, +/- 3 dB
Sensitivity 89 dB at 1 watt/1meter
Mms 4.22 g
Cms 706.4 um/N
BL 3.74 T*m
Voice Coil Diameter 25.5 mm (1-inch)
Impedance 4 Ω
DC Resistance 3.4 Ω

Qms 2.61
Qes 0.61
Qts 0.50

Any help would be greatly appreciated.

I could well be wrong, but these are the sort of drivers I thought would work in a Zigmahornet cabinet.

I'm not very enthusiastic about the ZigmaHorn.

I don't see anything in the specs that would preclude using it as a FR.

To help with the lowish xmax, the Frugel-Horn Mk3 might be considered.

Scott Buwalda, the company's creator classifies them as a midrange. However, the frequency response is what really draws me to the driver.

Thank you for the recommendation Dave.

Abob89......if you're not too far from Portland I have a set of Zigmahornets we could throw them in for you to hear before you built a pair.

I'm not far from the river.....at I-84 and I-205. Let me know when you want to cruise down. I can have an amp and source ready or you can bring yours if you'd like.

I thought 3mm one way x-max for a 4" driver was ok?

You'll be able to get down to ~80Hz if run full-range, perhaps a filter at 80Hz to reduce useless excursion at LF.

I mistakenly read 0.3mm. Yes 3mm (ie 6mm p-p) is lots.
