Drool.... New Morel Rohacell driver...

[Chris Roemer]

With the lowest note on a (7 octave) piano being near 30Hz, and a clavichord playing only 5 octaves, I'm guessin' that you lose either 1 (60Hz) or 2 octaves off the bottom end (120Hz), so ... PERFECT (for YOU) !

I actually do listen to chamber music.

[Chris Roemer]

Sealed? OK if you listen to Chamber music, I suppose. I don't think a clavichord can even do 60Hz?
No. Vented, w/a 3"id x 10" long rear port in 1.5cf. F3 in the high 30s. Fc @ 1.6k.

A pair of these woofers would go VERY NICELY with these tweeters, I suspect.

Probably crossover around 1800. Smallest sealed box as possible...

Suppose you were gifted these. And someone was making boxes for you.

It’s like any other speaker you build- how large a cabinet is acceptable.

based on datasheet I’d go with 1.5cu ft with Fb 27 for F3 42Hz;, as a woofer for a 3 way. Taking it up to 600Hz to a Morel 2-4” cone/dome

It would need a low-reacher in a 2-way, but my initial thought was a woofer for the TSCM634 and the Textreme SB tweeter. Maybe the TX tweeter would do it, but that's hard to say...

Wolf, if you're dreaming, how would use this driver and what would you pair it with? That is a beautiful driver, but its pricing makes my eyes water. Glenn.

Unbiasedsound, it's the grocery store that's killing me! And the electric bill and the gas bill and the water bill...

If inflation keeps rising I wont be able to afford anything at P.E. LOL

[Wolf]

Thanh, the high HD is what the driver is missing. The TSCW636 woofers I have measure REALLY low through the mid band. I expect these are no different.

However, I DID notice that the SCW/TSCW moniker drivers from Morel have taken a HUGE price hike. They are up about $120 over the previous retail cost.

Slobber, slobber, drool, drool. Where's that winning Powerball ticket???

Hope Sandy Claws was good to everybody!

Even if I could afford it, what could I do with it, that I couldn’t do with other drivers?

Some odd behaviour between 600-1Khz; and a mild shelf, which really limits it to a woofer use, but not displacement for a subwoofer.

The sensitivity is nice at 90dB/2.83V (8ohm)

I am missing something…

May end up in a lot of wish list but not too many baskets.

[dcibel]

They spelled Titanium wrong in the datasheet.

[DeZZar]

Ouch.

Here's the winISD file if anyone's interested. Change .txt to .wdr.

Get an f3 of around 34hz in 55Ltrs tuned to 32Hz. Max mechanical power of about 35watts.
