eclipse titanium info

[mikegett 10+ year member]

Does anyone have the driver parameters for the Eclipse Titanium series 12 inch woofer or the eclipse SW7100 series 12inch woofer? I am currently trying to decide between the two. I would like to go with the Ti 12's, but box space is a issue. If the Ti's 10 inch woofer would save alot of space I may concider it over the 7100's. Thanks any help.

Here are the SW9122 T/S parameters:

Fs 27.68 Hz

Qms 5.0

Qes 0.351

Qts 0.328

Re 5.9 ohms

Vas 32.4 liters

Sd 430 cm^2

Xmax 23.15 mm

Bl 28 Tm

Pe 1000Wrms

^all with voicecoils wired in series

Here are the SW7124DVC T4

Fs 27 Hz

Qms 8.58

Vas 2.24 ft^3

Xmech 34 mm

Sd 245 ? (this must be a typo, im guessing its around 460 cm^2 or so.)

Qes .55

Re 1.9

Bl 10

Pe 450Wrms

Qts .52

^All with voicecoils wired in parallel

If space is at a premium, the Ti is still a good choice as it will work in sealed boxes from 0.5-0.75ft^3 and vented boxes 1.5-2.0ft^3. The SW7100's are very nice woofers but work in slightly larger boxes, around 1.25ft^3 sealed and 1.75-2.25ft^3 vented.

Thanks for the info. In your opinion, do the Ti's sound better in a sealed or vented enclosure?

Sound is so subjective. As far as tonal accuracy the sealed box is the way to go, although the low end will be a little dry and somewhat underemphasized it will be the tightest sounding. The vented boxes, if designed properly sound fantastic and get quite a bit louder. Gun to my head, I would still recommend vented for most applications.

To be honest with you, the best box that I've heard my Ti in so far is a box that I designed years ago for a 12W3 when they first came out. It was 1.58ft^3 (net)tuned to 36Hz with 20in^2 of port area. It was tight, had great low end extension, and off of a 1000Wrms amp got very loud.
