I wasnt quite sure what the phase is doing between the tweeter annd the woofer. Thats why u ran some simulations. Crossover frequency is 1.9kHz. Obove is tweeter air motion transformer AMT, thats why purely resistive. Below is the woofer, having 0,7mH inductance and 5.8 Ohm active reistance...

This sub was from a good company that went under, and the sub woofer is a down firing. The sub seems to be changed and the amplifier is gone because it broke. Was one of the common faults with this subwoofer. Thanks!

Hi there again, Anybody who in one way or the other has been viewing any of my projects mite has noticed that I’m a great friend of powerful colours like my standard project colours of Mellon Yellow & Charcoal. Now as my project season is starting up again and I’m here in New Zealand going into...

Sorry to ask this yet again I did do a search but a lot of the info was posted years back and is unclear. There has been quite a few updates to REW since then. Is there a clear written guide on how to use REW to determine if Duel Subs are both in phase with each other. One is located Front...

A major problem in all my DIY work is the waiting for parts & items from overseas due to delays in freighting, availability or simple only through the unavailability of things here in NZ as well as of course everything cost down here so much more or just getting it here to NZ can get difficult...

Today we hooked up the bass bins only. We bypassed the Dirac, and crossover and ran the cable straight from my Yamaha CX-A5100 preamp to the Crest Audio amp. Can anyone explain to me why we have this result? Granted it is a 50db range, but is it normal for a Single woofer to respond like this on...

Beringer DCX 2496. How to sum channels A and B low frequencies to sub woofer? When using a single subwoofer as I am, isn't it better to have both the left-hand and right-hand low frequencies going to the single subwoofer? Please correct me if I am wrong. At the moment only the right hand...

Hello Gentlemen On a quality 6.5 LF driver, at what area is it best to cross it over at? The tweeters I'm working with start at 2.5 kHz. Finding it difficult to find a crossover that has 500 Hz, and 2.5 kHz crossover points. Have not been able to. Is it possible to connect two passive...

Pretty sure of it. Was listening at -4db levels of some pink floyd and pooof.... the right 8" woofer on the left speaker scratches on kick drum punches at anything louder than -8db now. it was after a calibration too. Not sure whats up. Gotta touch base with SVS on monday and look into if...

Hi guys Looking for advice on 18" woofer drivers. I'm about to under take (what I hope) will be my end game sub build for my two channel and HT setup. The project will be somewhat of a hybrid DYI and custom build in so far as I believe I've got the skills to build the cabinet but will look for...

Hi. I am helping a friend who wants to do a diy build. he is looking for a ported or sealed setup and has 400w @ 4ohm to provide to it, he wants to go 15" for that big deep bass. Hoping you may have some options for him without spending too much on a woofer Some we have found are Orion...

I am having trouble locating an audio cable connector. My friend has an older Cambridge Sound sub woofer. It has two inputs, left and right. I remember my first Boston Acoustic subwoofer also had two inputs. I remember using a Y connector with two short cables. Is this something that I can...

I am starting my next build. It is for a new center channel. The one I have is good it's not adequate to match my new mains. This center will contain (2) 10" woofers for use within the range of 150hz to 5000hz or somwhere in that range. I will also utilize a JBL D2 1.5" compression driver, and...

Hi, I am new to this area. Recently I got JBL 8" sub-woofer speaker and like to design a sealed sub woofer box for it. I would like to make it a powered speaker since I have sub woofer amp and power supply in hand. I read that box size matters for sealed box design. How do I decide the...

Just set up my HT, Onkyo TX-NR818 with a 7.1 speaker system, ATT DVR. All equipment is plugged into a Monster surge power strip. A coaxial cable feeds the tv signal to the DVR bypassing the monster power strip which I could use. I am getting a whump thru all woofers when changing channels or...

I dont see much on this subject around much.http://www.danmarx.org/audioinnovation/theories.htmlI have always thought it to be a superior way to do a subwoofer so I built 2 of them using some boston acoustics 10" drivers rated at 5 ohms each.Unfortunatly I could not find any other info on them...

All, I bought an Creative Sound Solutions(CSS) SDX15 while I was in college thinking that I would use it for a few months and then set it up wherever I move. Since then I have been in rentals and am moving in with my wife to a small house with our newborn. That means that it is unlikely that I...

My receiver has 1 preamp out for the sub but my sub has a left and right connection. Should I use a splitter and plug into both left and right for better sound?
