Default Morel transmision line with mw166

What do you think about this speaker project?

I need some good sounding speakers for Leach Super amp to replace my B&W 602 S 2 analitical sounding speaker.

Any comments are welcome!

Default looks good

I've never heard morel drivers, but just going by the specs and price and looks and materials used they seem to be one of the very best. I don't like their that some or all of their woofer have stamped steal baskets and foam surrounds. Although I know some people say foam surrounds are more effiencent and therefore sound better.

Dp you have to stuff the line? If so with what?

The Morel drivers have avery good reputation. I'd run the drivers thru Martin King's TL model to determine whether you can squeeze more out of the drivers.

1st order w impedance compensation on the woofer, 2nd order with an LPad on the tweeter. I'm no XO expert. I try to stay with 1st order or active XOs.

What you call stamped steelframe shouldnt be compared with other cheap drivers like the stamped frames of peerless and others.

I have a pair of 166 and a pair of 142. the frames on them is atleast as good as the scanspeaks i have and even harder.

Duct Seal or similar on the outside of the basket -- even cast frames usually need it.

I didn't expect the stuffing to be so simple. I guess the dark stuffing is rubber or something and the lighter stuffing is wool or poly fill or foam? Anyway it's very good, if I had the money and/or time to buy/build the drivers I would definately build it. I asked about the stuffing cause that's a big negative for t-line speakers from my perspective. Who wants to put wool in the first third, polyfil in the second, and polyfil in the last third. And make sure the stuffing gets less dense as you go down the line. Not to mention getting the allround density correct, so it's tuned to the correct frequency. And my personal favorite put in dowls and nets or whatever to make sure it doesn't settle over time. I know the stuffing absorbs resonances, but it's nice to build the line a little bit longer or bigger and keep that happy fluffy stuff to a mininum.
