I am looking for some wedges. Requirements: bi-amp capable(unless they a powered, which I am not opposed to), does not need to meet riders but if they do thats a plus, moderately priced ($1000 each), not too large because I end up on a lot of small stages(I was thinking 12''), pole mount would be a plus but is not a deal breaker, no rat fur. Thanks guys!

Check your pm's.



I'll be providing for a fundraiser next Sunday on the north side of Chicago if you want to come down and check them out.



Best regards,



John

Re: Wedgies

I have heard great things about the JBL srx712Ms and I think they are in your range if you already have the power to drive them.

I currently use 4 JBL PRX612Ms and 2 PRX615Ms and I am real happy with them. They do fit your criteria and are well worth a listen. The 615M sounds better than the 612 and is a bit louder too but both are plenty loud. The 615 is significantly bigger than the 612 though - I dont know what your definition of ''not too large'' is.
 
Re: Wedgies

Chris,

What is your timeframe on this?



If you are DIY inclined, we're currently working on a DIY coaxial wedge collaboration project in the DIY section here. Still in the planning/design stages, but likely something that will fit your bill at a reasonable cost.



If interested, check the thread out. For everyone else who might not have noticed this, feel free to share your input.

I'd check out the Yamaha DSR 112

Haven't heard them yet although based on Yami's track record I'm definitly excited to. They are low profile and come in a reasonable bit under your budget. No rat fur and are pole mountable.

And they have FIR processing and multi-band dynamics! Seems that the processing once primarily used in higher end offerings is entering the mainstream.
 
Re: Wedgies

I presume they'd try to keep it reasonable. Crossover point is on the higher side, 1.7K, so that works in their favor with FIR latency.



That's right, lower points require more taps don't they? That is a very high x-over point. And that 134dB of peak output is really high. Of course, I'm sure that's calculated and of course no frequency spec is given. So the reality it that it's probably really 126dB measured and at 3kHz

Yep, that's the reason you don't really see FIR's in use much below 500Hz. The latency quickly becomes unusable as the frequency is lowered.



Agreed 134 peak is probably meaningless from a real world perspective.

A 134 dB peak requires about a 107 dB sensitivity in the HF driver, getting 450 watts.

Hot, but certainly in the usual range for a 90 x 60 HF horn midband.



If the LF driver is about 96 dB sensitivity, it should peak at about 125 dB with 850 watts. 95 to 100 dB sensitivity for a 12 is typical.



I have buried my RS meter (126 dB) with a pair of front loaded Eminence Kappa 10'' with around 1000 watts of 200Hz sine wave at one meter. This matches with the 95 dB spec (+6 dB for two cones driven FTB) so the Yamaha specs look reasonable to me. Even with dead phones on, that level hurt, and the dB meter would not stay put on the table. The speakers did smell a bit, but sine waves have way more average power than most music, with normal music peaks in the 125 dB all day long should be possible for a high power 12''.
