New toys but not sure what to do with them

[Abob89]

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.

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

S'funny my tube friend said they look like that too.

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.

[Abob89]

That would be pretty cool! I'm Vancouver, just across the border

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.
