Separate names with a comma.
On/off axis frequency response measurements of both drivers are on page 1 of this thread, T/S parameters for both drivers are on page 2 and...
Everyone who’s posted a build thread on the Vortex-15 loves them. Anytime is see a diyaudio thread lamenting the lack of good coaxial drivers or...
Hi Matt, I’m designing an enclosure for the Vortex-15. I’m looking at doing a transmission line style cabinet with a width of 25” and wondering...
I was reading up a bit on the various Jensen Imperial enclosure designs for their coaxial 12” and 15” drivers and noticed how much their folded...
And as I mentioned in the first post, modeling your provided T/S for these drivers and my measured T/S in WINISD yields ported enclosures...
I should mention that when I do the added mass to get V(as) I orient the driver in an upright position, like it would be oriented on a baffle. I...
R(e) = 4 ohm F(s) = 40.7 Hz Q(ts) = .438 Q(es) = .47 Q(ms) = 6.63 L(e) = 1.23 mH M(ms) = 158.75 g V(as) = 99.3 l SPL (2.83v) = 96.45 dB this is...
Hi Matt, Over at AVSForum you provided the following T/S parameters for the Magnum-15 woofer: Sd = 881 cm^2 f(s)= 35.64 Hz R(e)= 3.93 Ohms...
Finally ordered a pair of these (b-stock sale). I appreciate all the technical info provided here and would love to see distortion data as well,...
I just got the Helix dome MTM kit so the following is an average of the four woofers from that kit. Re: 6.9 Ohms Fs: 44 Hz Qts: .44 Qes: .53...
I think I found the T/S for the 15” from an AVS thread: 15" Specs: Fs: 39.3hz QM: 12.12 Vas: 259.2 liters Cms: .249 mm/N Mms: 66.1 g SD: 856.3...
Since tower flatpacks for these aren’t in the immediate future, are there any T/S parameters we can use to model sealed vs ported?
I have two of the 16 ohm woofers used in the 88-Special. I finally got around to measuring them using DATS. The following is an a average of the...
Thanks erich. MTG’s tower design from post #3 looks most desirable to me, I’m assuming there’s ports placed on the rear for that enclosure. Maybe...
Any ETA regarding the flat packs? I really want to step it up from my Fusion 8 setup.
Even better method requires a very small paint brush (as small as you can find, think watercolor brush), a Dixie cup or similar and a can of flat...
Matt, An associate’s husband plays in a salsa band and want a pair of PAs for live shows. I think these would be perfect. If the Fusion 15 is NLA...
Great points, thank you. FWIW, my intention was to use the Vortex 15. I know you recommended a 18” sub to fill in the low end with the 15”...
I was thinking of a Yung SD500 plate amp powering the MBM. There’s an active crossover on it with a 200Hz maximum LP. The baffle width on the...
Any chance a sealed Vortex 15 could be used atop the MBM-15LX, crossover at 200Hz?
