Sorry, my bad. You worked on E145, which only exists in 4/8/16 ohm versions to my knowledge. The Mmd shown in the table for the unit was taken over from K145. But E145 have a fabric double roll glued...

The Vas you get is in line with what Giskard expected.
Maybe you took K145-8 values into WinISD?

K145 has Re of ca 9 ohms. It is a “12 Ohm“ driver.

But I would expect Vas results to be the...

Hi Frank, the change in Qts requires a re-alignment of the box for the new Q.

Assuming your measurement frequency is at (or a least near) the minimum impedance between those two reflex "humps",...

It's sacrilege, i know. Would still be interested to hear what those that jumped their own shadow have found out, though ;)
New year day is often pretty boring - why not get hold of a pair of...

Qts influences what we hear frequency/impule response-wise. Qts expresses the composite of electrical and mechanical damping near resonance. So even if the amp dampens less, there is still the same...

That two-port 28Hz tuning you like less is very similar to the 30Hz i have here. Instead of changes on the ports my cabs have, i just tried using a beefy transistor amp and gave it a 10ohm resistor...

Hi Frank,

the cabinets are 65cm deep, hence the (pictured, relatively long) Musique Concrète Le Cléac’h 322 horn + 2440 driver combo has ample space on top. I believe even a Jabo 72alu + DH1A...

Hello again,

i got myself two 115 l cabs made from stone (seller said it's polished slate). Unloaded they are 150 kg each. Took me a while to find people willing to help me lift them upstairs. The...

Would be fantastic if your contact could get hold of a C16RE145 or still have one in stock. If it doesn't cause undue effort, let me know if i'm as lucky as you are.




The calculator i have...

I wish you best of success with the new driver. Do you have a NOS recone kit to restore it or is such still available for E145 ?

I took your and Rob's hint at Giskard's remarks on page 2 and for...

==> But that's exactly what you would need to do, if your E145 T/S parameters have stayed firm at factory values over time.

Using the Hoge formulae, i get an f3 of 71 Hz in an optimum tuning...

I just got another K145, this time the later version K145-16. There were auctions for two of these from the same seller, but the second unit looked too battered for my liking.

The sample i got...

Well, K145 values in that table are also a bit off...

I got a pair of K145s recently and after measuring them for T/S, had them re-magged. After re-magging, i would have assumed them to meet table...
