Sir Handyman,

That's a really nice DIY speakers. I've seen it in the audio fair. Can you pm me how much would it cost me for a bookshelf design for a fostex 167e and for a TL design of for the 207. Can you also make a similar design as the omega speakers, yung parang fostex 167E ang driver na naka display doon sa fair. If possible pati sana yung front cover ganun din.

Thanks.

Sir Jerix, you can buy the lumber as is.. called laminated pinewood, they are actually factory joined pieces of pinewood. if you are referring to finish..i use polyurethane for the finish using either brush or cloth.

@sir Handy man

tanong ko lang po kung effective ang cork as damping material sa subwoofer? if not ano po masusuggest nyo na da best material for damping... thanks..

timn8ter · « **Reply #162 on:** Nov 23, 2004 at 09:19 PM »

If you are talking about cabinet damping the best is good solid bracing. In most cases that is all that is needed. If you need more, floor tile or ceramic backing board can be used, covered with 10 to 20mm of foam rubber.
BTW, all the drivers to make the speakers in Bon's pictures are available in PI at

relay_70 · « **Reply #163 on:** Nov 23, 2004 at 10:11 PM »

yup its for cabinet damping, good solid bracing lang pala ang kailangan... thanks for the info sir...

Thanks Tim.

If you have questions about DIY speaker stuff. Please don't hesitate to ask Mr. Tim Forman. He'd be happy to answer all our questions...Right Tim?

timn8ter · « **Reply #165 on:** Nov 24, 2004 at 12:41 PM »

I will do my best.

jerix · « **Reply #166 on:** Dec 07, 2004 at 03:03 PM »

Mr. Tim -- or anybody

I got a non-ported surplus speaker and being non-ported, it is alil bit hard to drive--- so,, i am thinkin of drilling a hole in its back panel -- maybe 2" wide to allow flow of air... what do u think guys, will this work? thnks

av_phile1 · « **Reply #167 on:** Dec 07, 2004 at 03:33 PM »

Not adviseable from my view.. Drivers meant for air suspension type baffles may not perform as well or better in a ported enclosures. The driver compliance is often matched to the baffle volume and resonance traits so that putting a port will not necessarily enhance the efficiency or the LF extension. There is also such a thing as tuning the port using different tube lengths and port sizes that are derived from some equations in speaker designs ordinarily using computer aided design software. Let this not dampen your tweaking efforts, just don't expect dramatic improvements, if at all. Anyway, you can always cover up the hole if it doesn't work.

Just my thoughts.

Nope, the speaker baffles you got were designed that way - let it stay that way. If its hard to drive then it is assumed that the sensitivity of the speakers you got are low - you will need an amp with more juice to drive your speakers.

Cheers.

There's no way to know what the results will be since we don't know the electrical or mechanical specifications of the driver. Even if the driver were acceptable for use in a vented enclosure that enclosure would most likely be a different size than the sealed one. Then, as av_phile1 says, we don't know what size the port should be.

jerix · « **Reply #171 on:** Dec 08, 2004 at 07:21 AM »

Jagner, tim: thnx for your insights too bros.

I will surely be guided by these principles once i will make my final decision to open or not to open.

This is a variant of Martin King's Project 5 http://www.quarter-wave.com. Similar performance in a more interesting shape and the addition of a horn super-tweeter.

Superman · « **Reply #173 on:** Dec 12, 2004 at 04:17 PM »

tim, this is great especially for SET-lovers!...are you also going to do something similar to this???

timn8ter · « **Reply #174 on:** Dec 12, 2004 at 09:53 PM »

That is the pair I built for myself. Yes, it is an excellent design for tube amps.
