Dave, can Thirlmere or ThirlmereR be option for CHP70.2? Did you put some low pass on versions with CHBW or EL70 when you used them with small onkens?

Yes.

I am putting the CHBW in mine. The CHBW and the CHP both fit the same boxes.

I just finished the compact series chamber tuned floorstander that Scott posted- I thought the design looked cool and went for it. These are my first full range build and Iím very impressed with the sound given the size of the driver. They have a really nice relaxing sound to them and, to my surprise, they did remarkably well with pop and hip hop at lower to moderate volumes. Awesome!

I have one question though - how exactly does this design work? Ive heard of dual chamber reflex but this seems to be three chambers? Iím pretty sure Iím hearing frequencies as high as 250hz coming out of the port.

I really want to try making something with the 11ms drivers now. I am thinking about the nostromo, water Buffalo, or pensil, but canít decide whether the extra construction efforts for the water Buffalo or pensil would be worth it.

Any thoughts on the SEAS FEA18RCZ 7" driver? I'm curious to here what Scott thinks... Thanks

I suspect the FA18 being smaller may be better mid/top than the FA22 which is quite good.

The response looks a bit ghastly at first glance, but it's plotted on a different (less flattering) graph scale than the FA22, and Seas being Seas, you can more or less guarantee that graph is reasonably accurate, which is more than can be said for some. I'll have a ponder. A number of possibilities.

I appreciate that guys! I have built projects using a number of different full rangers including Jordan Eikona 2, Alpair 7.2, Alpair 7.3, Alpair 10P and recently Alpair 11MS all with good results. I do tend to lean towards more of a laid back sound with warmth and "gushyness". I had read somewhere that the big brother Seas FA22 had that characteristics but the size of cabinet it just a little big for me.. I'm hoping the smaller FEA18 might fit the bill....
Thanks again for your thoughts!

Hey Scott, sorry to bother again.. So how about that Seas FEA18RCZ? I was looking at the 19L slim front baffle version noted on the Seas application note for this driver. Is this the best option, or should I go a bit bigger for a lower Hz tuning?
Thanks

That's definitely not a warm and gushy looking response curve.
