that's a very nice response.
if you can post the impedance, that would be great too.

Hello,

I am about to build myself a pair of Small Thor in the following months and I have a few questions I believe you folks can answer for me.

1)

Can I modify/convert the pipe port to make it look like the original? Still on the front though. Here's a picture of what I mean:

Click the image to open in full size.

I suppose the volume of the port itself must be kept the same.
3" x 4" pipe equals 463.33 cm3 or 28.27 inch3
179 x 65 x 40 mm rectangular equals 465.4 cm3 or 28.40 inch3

(23mm MDF: 9" - 2 x 23 =179 mm)

2)

What do you think of an active crossover?
I already have all the amplification needed and a miniDSP 2x4. Using the miniDSP for active xo would save huge money. The miniDSP would also make it easier modifying the xo for one to two midrange drivers.
Does the two midrange drivers get identical signal from the xo or would I need one more miniDSP?
Maybe it's just stupid?

3)

As of now I have the two tweeters and one pair of midrange drivers.
I will not be able to afford the second set of W18E for atleast a month or two: is it possible to use just one set of midrange drivers in the Small Thor cabinet? Ofcourse I don't expect the performance of a Thor, but it would be nice to put my drivers to use and to get rid of my current speakers.
For this to work I expect a different crossover and that would not be a problem with the miniDSP.

Thanks in advance

Björn, Sweden

I think usualy in MTM configuration the signal is the same for the two midrange. You can use a miniDSP 2x4 and 2 way advanced plugin for this configuration. If you go for active,you must be able to measure your speaker with a microphone, a PC and a software like REW or ARTA.

Yes. You must maintain the area & cross-section, not the volume. It should be noted that the original had the terminus on the back at the top.

Off-set needs to be maintained, you can't push the drivers up to the top as pictured in the Usher you posted.

Sounds a good idea. You'll have some work to get all the details right.

You could do a halfThor by having the cross-section of the line & the terminus.

Uhm. Maybe someone could draw me an idiot friendly .bmp?
It seems I'm having difficulties with techy talk.
So if it's not the volume of the port that affects performance, what is it really?

Default What size Amps for the Thors?

Hey guys,
I've been thinking........................

I'm driving my Thors with an F5, not the turbo model. I was given a pair of Carver A-220s and just for fun hooked 'em up and listened for the difference.
The "drive" is so much greater with the carver I was shocked. But, there is a "Live" presence with the F5 that almost brings tears to my eyes when listening to Alison Krauss' s voice.

Dave, you stated that we should use 750Watts for optimum performance earilier. Whoa. That's a lot more than the F5 is capable of.

What are you'all driving the Thors with? and what is your wattage?

Any opinons on the Carver's quality? I could even use them as Mono blocks @ 375W each.

Thoughts?

Ron

Ron -- did you adjust for gain -- a few tenths of a dB will make a difference.
