How can I make this design more SQtastic (yes I made it up)

Audiophilenoob · 29th May 2005, 04:39 AM

here's a pic of my design I'm starting on:

http://feandil.tripod.com/PartII/my_dream_towers.JPG

it's a 2 tower line array per side

it contains:

4 15" Lambda TDX midbasses tuned to 35 hz or so in a black finish (professionally painted)

8 Audax PR17 midranges in sealed with a 18" deep chamber

1 DIY ribbon linesource with about 106-109 db efficency using a planar aluminum sandwich...

xovers are all active... with a Behringer Digital...

2450 watts to midbasses..
2450 watts to midranges
400 watts per side to ribbons (max)

xover points are 300 hz LP for Lambdas, 2-2.5 Khz for midranges, then up
any way to improve the SQ here?... I'm going for perfect SQ

well as close as I can get

I'll be more than happy to provide you with advice that will easily make this pair of speakers worth at least $100,000 . You have some significant design flaws and since we'd be skipping the Ebay commission, I'll assist in the design for the bargain fee of only $999 and shipping is free anywhere in the world. For a limited time, I will include a set of plans for a compact bass horn array absolutely free. Why go ported when you can get more bass output with a smaller cab using more economical drivers using a bass horn array ?

With the efficiency of those speakers, this much power is ridiculous... as has been very well established there is a fairly solid inverse correclation between amplifier output quality & quantity...

you have an opportunity to use some really nice small amps here.... why blow the sonics by using welders?

If he can't provide a decent link, I'm not interested. I'm not going to jump thru hoops.

PS if you don't already have the Llambdas you are probably out of luck, and the PR17s, it seems, won't be around muh longer.
