Default Peerless 830987 3" full range in dipole

Hi Folks,

I am experimenting with a small OB design and would appreciate your feedback. My goals were to develop a room friendly dipole by using a 3" full range driver. A helper woofer is used to address dipole cancellation.

I am very pleased with the Peerless 830987 (inverted surround version of 830986) and have documented my findings below. Even though my project might be considered a 2-way, I thought this might be helpful to those of you who are looking for an inexpensive apt driver for true single driver application.

Love the simple baffle design. I was thinking about something similar using the 'full range' PE buyout for $10 but my sims were somewhat disappointing with similar baffle dimensions. It may sound better in real life tho... Your project is inspiring!

My experience with software simulation in dipoles has been somewhat hit-or-miss, much more so than with conventional designs. I built a simple test baffle with panels that slide on both axis allowing for multiple height/width combos. Of course this is only helpful when you have the driver in hand, but it seems to be a good way to model a baffle in the particular environment your working in. I wouldn't be surprised if PE buyout sounds better than it actually modeled.

Hi matevana,

I checked your design using MJK:s program... Seems you made a good design (compare with my simulations). Noticed the low FR corner that can be extended with a good monopole sub..See the T-TQWT using an additional Alpine woofer.

I just recently (this week) bought some of the Lagan beech counter top from Ikea, and can say that it seems well constructed, solid and fairly heavy in its sheet form. Its going to be used for a flexy table/rack build coming soon. It seems like it would be great for dipoles, or any front baffle...

The write up looks great, and is filled with useful information. Did you consider any other 10" woofers?
