I want to replace my existing JBL Studio center. I wanted a 3Way center with an AMT tweeter, but my size restraints has made that nearly impossible, so I started designing a two way instead. I liked what I saw so much that I also designed side surrounds with the same drivers.
Tweeter: HiVi RT2H-A which is sort of like a horn loaded ribbon which might sound close enough to the Mundorf AMT tweeters in the L&R mains and can be crossed fairly low at 1700 hz. This is the closest thing I can find to a spec sheet.
HiVi RT2H-A Speaker Driver Isodynamic Ribbon Tweeter Shielded 30W 8 Ohm - Audiophonics
Woofers: 2 SBAcoustics SB15CAC30-8 5" ceramic woofer- 8 ohms in 5.7 liter sealed chambers. I'm using the same mid woofers as mid range in the fronts so they should match up nicely. Here the spec sheet.

The side surrounds will use the same HiVi and one of the SBAcoustics mid woofers.
Has anybody used the HiVi tweeter before? If it is good as it modeled I will go with it. I was able to get a LR4 acoustic slope with a single cap and a parallel notch filter. The mid woofers only needed a 2nd order electrical filter to match up almost perfectly. At this point I'm using traced FRD and ZMA files so it will require buying and measuring the drivers on baffles to be sure.

Looks like this is a no go, the HiVi needs to be crossed much higher, I will see if the Aurum Cantus AST2560 will work instead.
That HVI RT2H-A was only 30 W rated anyway. 5 db down @ 14 Khz up.
I'm listening now to a pair of Peavey RX22 compression drivers that are 8 ohms, rated at 60 W, and are 5 db down @ 17 khz. They are crossed at 2000 hz and the speakers are rated 500 W rms. SP2(2004)
In the SP2-XT same CD but crossed at 1200 hz, the speaker rms watt rating is 300.
Real ones are only about $160 + freight here instead of E99. You have to buy a suitable 1 3/8" threaded horn. I got my two horns used with 2 used drivers, $140 on ebay.
Lots of "replacement" RX22 on ebay, probably not ferrifluid cooled and probably not titanium diaphragm. Probably not Peavey QA either. You'll have Peavey dealers in the UK Mine here in the US are parts-express.com and tubesandmore.com
BTW I love the sound. Most accurate piano reproduction I've heard in this flyover city.

I don't have room for a CD and horn in these designs. I'm now looking at the Beyma TPL-75, the spec sheet recommends a 1200hz or higher XO, it should be OK with an 18db XO at 1700 hz. Each driver change is bumping the cost up by $100.00 but I'll pay if it does what I need.
