DIY110 practice cab...

I'm going to build two very small 110 cabs using my BP102's, along with one Goldwood GT-1025 tweeter in each cab.

The BP102's SPL is 92 and the Goldwood tweeters are 90. The BP102's range from 40 to 2000 Hz. The Tweeters go from 1800 to 30,000 Hz.

From what I gather I can wire the tweeters in parallel with the BP102's without using a crossover, correct? Let me know if not.

These cabs aren't going to be anything other than very small cabs to take back and forth to practice, or rehearsing on my own...or maybe small, coffee house type gigs.

I am NOT going to use any other speakers, so please don't waste my thread with suggestions of other speakers, as I already have the BP102's and want to make use of them in some small cab. I also have a limited budget (read; I really don't want to spend anything, except what I absolutely need).

For my purposes, I just want some opinions on the following...

Tweets can be wired in parallel with no crossover? Please no reference to website info that reads like SPAM novels. Thanks.

Would you make a ported or sealed cab with the BP102's? Remember I want these to be SMALL cabs, not necessarily loud, or low.

If you did port them, would you tune them to 40 Hz (I play a four string), or perhaps 60Hz and get the mid bump?

Any other info aside from suggestions for other speakers would be greatly appreciated. These are just for basically practice and I'm looking to utilize my existing speakers in something extremely portable, as I already have small, kick ass 115 neos for gigs.

Mucho thanks.

 

What do the cap and resistor accomplish? Does it force the tweeter into accepting ONLY frequencies above a select point? It appears (from what I've read) that tweeters do accept some lower frequencies, but at such a minimal amount as to not even be noticeable. Perhaps I'm wrong on that, but it's hard to get through the technobabble.

Yes, the ones I'm looking at are Piezos.

 

What cheap amp are we talking about?

Is it necessary to use a resistor IN MY CASE?

I simply want to wire up a small 110 cab with a piezo tweeter. Anything wrong with wiring my BP102 with Goldwood GT-1025 in parallel?

 

I'll be using my Superfly head (4 ohms per side...and the BP102's are 4 ohm speakers). What the heck is a plate amp? I don't think I would ever buy an amphead from partsexpress anyway.

 

Thank you. Makes sense for a a subwoofer in a car stereo or home theater.

I wouldn't use one for practice though.

 

Yup. In a couple of other threads I posted. I am aware of other cabs. Thanks, but I'm just looking for answers to my specific questions.

 

Yes, I've been playing around with WinISD for this. I just like to hear other's thoughts on it. Sometimes a person relies too much on software and less on their ears, so anyone who's built small 110 cabs might offer up some opinions on what's worked and what hasn't.

I know I can get that mid bass hump by tuning it a certain way, and BP102's have low sensitivity, so I'm messing around with all kinds of scenarios.

 

The Omni 10.5 (110) is only 16" deep by 20" wide and 13" tall. It's half of a full Omni 10. Hard to get any smaller than that. The full Omni 10 is twice as tall...same other dimensions though (which is pretty small for a full 210 cab).

But if I build a sealed 110, it would be smaller than that. Even a ported front loaded 110 would be quite small. Even at that, it wouldn't be much smaller than an Omni 10.5, and more than likely not as loud as that either.

But Bill himself says the BP102 isn't the best driver for an Omni and I want to use the speakers I already have.
