Hi-vi trinity 6 in a horn enclosure?

[sqlkev]

Anyone know if this driver will work in a horn box??

here are the specs

I just steal these on ebay

You can use most drivers in a horn, assuming it's properly designed. But without knowing Vas (one of the most important driver parameters, which they haven't bothered including on the data sheet) sizing it accutately might be a problem -you'd have to over-size it, and damp it down if necessary

here's some more info of the woofer from partsexpress

Woofer specifications: *Power handling: 40 watts RMS/80 watts max *VCdia: 3" *Znom: 4 ohms *Re: 3.2 ohms *Frequency range: 63-1,200 Hz *Fs: 63 Hz *SPL: 90 dB 2.83V/1m *Vas: .20 cu. ft. *Qms: 2.50 *Qes: .46 *Qts: .38 *Xmax: 2.7 mm.

Yes, you can design a horn easily enough for that.

is there any easy to use modeling program that I can play around with?

many thanks,

Look into the BIB, there was a small discussion using that driver in a BIB, but was not going to fit the appplication after all. There are a few people still lurking around wanting to see the outcomes of a project using that driver.

Thank you for the info,
anywhere I can get some drawings of such BIB?

thank you, Dave!

I'll build these in a couple of days and will report back.

Greets!

FYI, when I reverse calc BL using the published Cms I get a Sd that's considerably larger than the driver (~22.78" effective piston diameter Vs a 17.3 cm published overall dia.) and a BL best suited to compression horn loading, yet the 90 dB sens is about right with the PE specs, so not sure what's going on.

Calc'd based on Cms = 2.409 mm/N (published):

dia = ~22.78 cm/8.9685" ------ o.d. of driver is only 17.3 cm, so the rest are suspect!
Sd = ~407.55 cm^2
Mms = 265.3113 g
BL = 27

Anyway, scaled some dims off the PE picture:

effective outside dia. = ~13.1934 cm/5.1942"
effective inside dia. = ~7.252 cm/2.855"

calc'd:

Sd = 136.711 cm^2 - 41.305 cm^2 = 95.406 cm^2
BL = 6.3226 N/A
Cms = 4.3963E-04 mm/N
Mms = 14.5169 g

Sim of previously posted BIB: http://www.diyaudio.com/forums/attachment.php?s=&postid=1269969&stamp=1186116360

TC's BIB optimized for the T6:

L = 138"
zdriver = 30"
Sm = ~30.758"^2 (recommend ~4.687" W x 6.562" D)
a-b-c = ~3.281"

GM,
do you think the odd piston area is due to the large diameter mid/high area? That threw me off when calculating too. It seems to have the effective area of about a 4 incher.

No doubt, but the published Cms spec doesn't make any sense regardless.
