Hi All
I am new here and was drawn to the forum when i was searching for mods for the RTL3.
Yes bass is great from this budget speaker, but the highs could be tamed.
Mine are 17 yrs old.

Vikash what tweeter did u settle on. Vifa?
And yr X over mods entailed better components and just the L pad pots?

Vikash ? Which TDL model??
I know that in some with dual woofers they used woofers with different impedances to even out the load on the amplifier, so having a driver with 16 Ohms sounds about right, the other in the box should be 8 Ohms (Nominal)

Greetings all

For anyone who is interested due to a failed bass driver i reworked the speakers completely and this thread was one of the references used so only right and just i post my results back .

Orignal mid/bass units were apparently based on SPH 175's with some changes requested by TDL. As i wanted to "upgrade" i built a config around the SPH176, similar but more powerful unit it received good reviews from a german reference and was used in a setup herre which helped point me in the right direction:

The tweeter was replaced with Morel Cat378, mainly because its the same size, is reasonable priced and its sensitivity matched the twin 176's so the crossover was easier.

The original crossover components were all v cheap and having replaced a burnt crossover not long after purchase i noticed when refurbing that despite being an RTL3 part the cossovers weren't identical! I could only win from there...

I plotted FR and impendance curves from the drivers and used the Bagby spreadsheet to get an understanding of what results different component values gave.

After some listening and tweaking I ultimately built a first order crossover using poly caps and air inductors with zobel for the woofers.

Its fair to say the speakers are far from what they were - very enjoybale, shame i would need to buy a stadium to let them really sing . This was some time ago now but happy to dig out the specifics and photos if anyone's interested.
