How do they sound?

Re: Introducing SALT a SB13-Infinity 2-way

very nice. at first, that tweeter seemed a bit fatiguing, but I smoothed it out. that little sb13 really has some nice bass.

Re: Introducing SALT a SB13-Infinity 2-way

Also the Infinity tweeter appears to be quite sensitive. What is the estimated sensitivity of that tweeter? Do you think it can be crossed at 1500 hz as in Infinity Cascade models 3c and 3v?

Can you elaborate your LCR network in the tweeter pass. What is its effect?

Thanks in advance.

Re: Introducing SALT a SB13-Infinity 2-way

without the network, there was a huge peak around 7k. it is very sensitive. would have been better to use it in a mtm.

I didn't see how low it could go. fs is 1600 on one of them, a bit lower on the other.
I did do a distortion measurement and the tweeter looks good where I have it.

digging the white texture Arlis - I guess those are the CNC baffles you talked about.
You're right about the SB13 bass. Pretty amazing, really.

Yes, enough to be enjoyable. I spent a few hours listening to them yesterday. The others are on top of my thin towers in the living room for now.
I have two of the 6.5 .tangband subs and a couple small plate amps so, eventually, these will be in a 2.1 setup.

Nice post , thanks for sharing
Any plans for an MTM ?
I picked up a pair of those Infinity tweeters but they haven't made it off the shelf yet

Infinity Prelude Forty also has an 1" CMMD tweeter in a waveguide, which is similar in appearance to the one used here.

According to the test results.

Even at 100 db spl level the tweeter distortion appears to be down 50 db(0.3% ?)

It appears that Revel has taken over the highend of Infinity brand in recent years!

no, but I bet BDaniels could make some baffles for you. Mine didn't have room for paint spills!
I probably could work up a crossover if needed.

Re: Introducing SALT a SB13-Infinity 2-way

Lowell, they look great! Looking closer at the baffle, you could probably eliminate the LCR notch on the tweeter with some judicious use of felt around the faceplate of the tweeter. I imagine it would smooth out considereably. Some gray felt would not appear out of place (too much anyways) on that baffle. You could trim it to roughly mimic the shape of the SB woofer.

Thanks for the heads up Arlis_ but I think I can do the baffles okay , just the crossover has me stymied .
I bought DATS . the Omnimic and a Galaxy Sound Meter along with Excel but between watching the grandchild , classes , homework and maintaining the estate I haven't made any progress so far.
Right now I'm working on a new birch baffle for some Seas 8 inch full rangers for a 2.8 ft. cabinet for the living room . Simple contour circuit by Seas and an impedance flattening network. My SET amp will like them.
I've got the Infinity tweets in storage for a future project.A pair of the buyout Klipsch Tractrix horns too .
I'd like to find an efficient paper woofer to match these to that will play nice with my tube amp.
Do you think the SB13's are a match for the Peerless 83075's ?

Re: Introducing SALT a SB13-Infinity 2-way

the 830875 has a big breakup kind of low ie distortion. the sb will go higher. I guess if I had a tweeter that would cross low, I would use the 830875.

I tried a 1/2 inch piece around it. It was a little lumpy and this morning it had come off. I also tried a large piece and had a hell of a time cutting it to match. I don't mind the notch so much. The holes do bug me though. I might try some more. I have some light grey as well as dark grey.
