[/quote] Been busy doing a combination of DIY and nothing the last week or so - so the build is no further on. However, am hoping to have it making noise by the weekend.

alexclaber Posted March 31, 2008 Author Share Posted March 31, 2008 Right, I will get back to the woodwork tomorrow, I promise! The car is an '03 Honda Civic 5-door - very spacious for its size. Alex Link to comment Share on other sites More sharing options...

Just had a breakthrough on the design of an improved crossover which takes into account impedance and phase variations. Alex Link to comment Share on other sites More sharing options...
barneythedog Posted March 31, 2008 Share Posted March 31, 2008 Sounds like good progress being made Alex! I've been playing with WInISD myself recently, and was just wondering if there were any anticipated issues with group delay? This may of course be a totally stupid question, as I'm not really sure what I'm talking about Link to comment Share on other sites More sharing options...

[/quote] Yes sir! Just had a bright idea for a compact cab using the 2510-II for low SPL use. Pluggable ports for three different alignments (normal tuning, low tuning and sealed) to reduce the lows in small boomy spaces (i.e. my drummer's loft when we're recording) or gigs with big PA subs. No tweeter or midrange but some cunning circuitry to reduce the midrange and extend the treble, so it'll be pretty directional but that's what you want in a personal monitor.

The Funk Posted April 15, 2008 Share Posted April 15, 2008 Looking good! Really intrigued by how this will sound. It makes a lot of sense to have a mid-range speaker and not bother with a tweeter. Link to comment Share on other sites More sharing options...

Certainly the Omni15 without the HF elements sound lifeless to me (even with the horn loaded mid range driver), howevor some other users dont even notice if the horn is on or off. I am just replacing the HF element in my Omni 15 with a slightly more sensitive HF melded array to lift up the top end a little more. Cant wait to see the finished box Alex !

I am just replacing the HF element in my Omni 15 with a slightly more sensitive HF melded array to lift up the top end a little more.[/quote] I've decided to initially try this box without any padding on the midrange driver, so the response will rise by about 3dB above 750Hz: i.e. the plot will follow the light blue line until the purple line rises higher and then it'll follow the purple line. Either way the midrange ends up -3dB @ 5-6kHz and -10dB @ 9kHz. Obviously it won't have that tweeter sparkle but it should have enough treble for most bassists. The Omni 15's midrange speaker being horn loaded doesn't go as high (horn acts as a bandpass filter) so I'd expect that to have more need of a tweeter, which the no tweeter plot confirms. Am thinking I should have just used a strap handle, this cab's so light that recessed bar handles are overkill. Alex Link to comment Share on other sites More sharing options...

I think we're looking at easily under 40lbs complete, which will be amazing! I bet the Omni 15TB has that same psychological affect of feeling even lighter than it is because you don't expect such big boxes to be light. My RIM Custom 5 is like that too - maybe an ounce or two lighter than my Warwick but feels lighter because it's that much bigger. Alex Link to comment Share on other sites More sharing options...

I have three words for this evening: ****ing tee nuts. What a ****ing pain in the ****ing neck. Wood screws into three layers of 9mm ply in future methinks... Also, been fitting the port and it seems to need to be much longer than the calculated length to get the original planned tuning frequency. Bizarre.
