TAD 2404 Build

[Ian Mackenzie]

Have you checked the voltage drive of the crossover on the Tad driver?

It might be going too low

Suggest you inspect the diaphragm.

Are you the original owner?

Thanks a lot for your reply!

Are you certain the original ports used in the TAD 2402 are 105mm in length and 100mm in diameter? Is the internal net volume really as low as 135liters? The enclosure looks bigger and my guess would have been around 150liters or more...
Have you owned this enclosure or where did you find these info´s?

My TL-1603 seems to have pretty similar TSP´s to the TL-1601a in the 2402 enclosure according to TAD´s specs. So it should behave similar in the same enclosure I guess...

TL-1603 TS parameters are the same as the 1601b which requires a bit larger volume than 1601a.

Two ports 100mm diameter and length of 105mm is was is written on plans available on Internet. Taking the Port length formula from the previous page, makes Vb of 129L matching two ports of 100mm diameter and 105mm length for 32Hz.
135L is the volume I estimated from the plans, some people are talking about 125L, so 129L is a credible value, between the two of them.
I tried two ports of 100mm length of 105mm this on my exact clones of 2402 (missing dimensions can be easily deduced, panels thickness is 22mm, bracing 44x60mm) and it was working well, unlike port length found using WinISD.
