my peerless pipes

geitmans · 27th October 2003, 04:15 PM

Finally my speakers are finished. This is my first pair off speakers I build. As a student I needed something I could build on a small budget and these where relative sheap to build. These peerless units are a good deal price/ performance. I'm using the shielded version off the wa10.

First impressions: Real powerfull bass , more than enough for a small (12 m²) student room. The highs are less pronounced for the moment. But I need to find some decent measurement equipment so i can change the crossover a bit. I couldn't find any decent priced non inductive resistors here so I just used the white wirewound types maybe this is a part off the problem. I was thinking using a few 2 watt metalfilms in parallel. Anyone done this?

I'm drving them with my aleph 5. Next on the todo list X-bosoz.

I'd like to thank Bob for sharing his design.

the making off

I used asphalt roofing for interior damping and adding weight.

the crossover

Round over was done by sawing 45 degree cut and sanding.

I used some regular inexpensive satin-gloss black paint from local diy shop.

Nice set of speakers. Can't you find some mox resistors for the crossover? Paralleling filmresistors is an option, but you need at least 4 watt and 8 -10 watt is recommended to reduce the heat.

I finished my Peerless Pipe two weeks ago, although mine does not look nearly as cute. I emailed Bob Brines, he recommended to change L1 to .15 mH to smooth out a "peak" at 4.5k or something like that. The new cross over make the high more lively. However, if played loud, the high can be a little aggressive to my uneducated ears. The Peerless pipe is a very good speaker considering the cost of the drivers. The bass is incredible for a smaller woofer. Wonder what it can sound like with a more fancy tweeter.
I also like to take this opportunity to thank Bob for making this project available.
