Peerless Tymphany 830880 5.25" 6mm xmax passive radiator

[Mike Cason]

I use 4 of these passive radiators in my Bang and Olufsen RL 60 modification but Tymphany has recently discontinued them.

I have been in touch with the Tymphany Company in China and they are building a large quantity for me at this time. They work in other applications as well, especially desktop speakers for computers and Ipods needing the extra bass extension and are also used in small mains and surround sound speakers.

Leveraging the best in Danish craftsmanship, but manufactured to be very affordable, these audio transducers are ideal for use in small surround sound systems, but can also be used in a wide variety of end user products and applications.

I've recently purchased 16 of these passive radiators and should have them in stock by 10-26-09.

Tymphany should have my order finished by November 30. I should have them here at my facility around Jan 1st.

My shipment came in and I've already sold out of these passives. I'm having my freight company deliver them to me quicker. I'm hoping to have them around December 12th or so.

They model out well with my A3s and soon to be released woofers; both the 5" and 6". What an excellent choice for a small full range cabinet with some very good bass.

I've made a major score. I've purchased the last 75 passive radiators that a distributor had held back.

I should receive them on Monday. My order from China will go by boat to save some money.

Below are a couple of graphs using the 830880 passive radiators. These are preliminary software results.

The bottom graph is using the Tymphany passive radiators with our soon to be released Audience W6 woofer.
Here is a quote from Audience's engineer: A one foot outside dimension cube with 1 W6 driver and 3 of your PR’s all properly tuned now will do the following, see graph. (The zero point is 102db) That is 111db @ 22Hz for a stacked stereo pair near a rear wall. Audience's much bigger stacked cube 12” driver sub has slightly more output capabilities but only down to 25Hz. As you can see this small sub will go down to less than 22Hz, a 12% improvement! And all this without overdriving the drivers or the PR’s. This is a serious output level. Of course it requires a serious amount of input power as well. A lot of efficiency is given up in the tuning.This is some exciting stuff!

The first graph is a graph showing what a Pr will do with 2 Audience A3’s(in red and without the PR’s in gray). This is a 5db boost from 75-100Hz!
