crossover

Hello all. I added a subwoofer to my setup, and I am doing measurements with REW and a Umik-1 to help me set the crossover and generate some EQ filters. I was hoping I could get some input on the measurements I've made and see if anyone can provide their input or guidance on how to choose...

Hi All, I've only discovered this awesome forum earlier in the year, it has been great fun reading through all the detailed reviews and forum discussions. My background is in car audio (many years ago), which is probably why I am asking this question. About 6 months ago, I started researching...

Hey everybody. In my fairly large room (l-w-h 26’11” x 22’4” x 8’10” or in the metric system 8m22 x 6m82 x 2m70) I have sincere modal issues. I will try to see what I can do with using multiple subs to combat these. This however would imply crossing over the subs pretty high (80, more likely 90...

Hi everyone, I have some thoughts/questions about creating filters for my new speakers. I built the kingroy mk3 kit by seas and want to use the fir capability of the hypex amps. Right now I use the dsp preset 1 provided by Seas. I used the mmm technique to measure a sphere around my listening...

Hello, I've a pair of replica JBL 4345 which I've been 4-way actively bi-amping with the DEQX Pre-8. I'd like to add 2 subwoofers to the mix, and that means I'll have to free up 2 of the 8 channels from the Pre-8. My idea is to make a passive crossover for the horn (JBL LE 85, 8 Ohm) and...

hi there, this forum was quite useful to me during the setup of my as precise and neutral as possible 2.1 system setup so far. It is a desktop setup which i wanted to share with you since it somewhat reached a level where i thought there may be other people who share the passion and want to give...

Imagine an interesting new product: Two sets of analog inputs (when I say sets, I mean each set has single-ended and also balanced), one volume attenuator that controls output synchronously BY WAY OF TWO SETS OF SYNCHRONIZED RESISTOR LADDERS (analog-domain attenuation, not digital) between the...

I'm building the CSS Audio's 3TD-X and was planning on laying out the circuits just like they are on their 3D printed board (see attached photos), and thought it'd be fun to replicate Gabster's crosstalk experiments. I have a small speaker wired to an 0.75mH air core inductor (litz wire , but I...

This is my first post and just created my account today to post this. Here's all I got to say.... DAC/PRE-AMP WITH BALANCED outputs and a SUB OUT with HIGH PASS for the MAINS. Imagine a world where us simpletons with active studio monitors could integrate home theater subs without dodgy multi...

Hello, first post on this forum. I have a pair of Totem Staff tower speakers and am guessing they are from the late 90s/early 00s. I am generally happy with the sound but am tempted to tinker. There is sand in the mass loading chamber in the bottom, but the inside does not have any polyfil or...

Hi everyone, this evening I reconnected the Martin Logan Quest and as always I had difficulties. Used in monowiring they sound decent, although perhaps the panels should be cleaned, I almost never use them. Used in bi-wiring, moved the rear selector, one of the two speakers sounds lower. So...

Hi all, I have a really "simple" question about crossovers settings on a receiver (in my case it's a Denon x3800h) that I can not find answer to. So, when I a set a crossover let's say 60hz (my mains reach easily 25hz), all the frequencies between 25hz and 120hz (provided I left the LPF at...

It has served me well, but I've grown tired of my current crossover. Today, I noticed that I hadn't listened to music in weeks, and when that happens I usually suspect something amiss in my rig that is keeping me away from sour. I noticed two woofers on the left channel were not really...

Picking up a speaker restoration I started last year, but had to stop due to a death in the family. Technics SB-R3 rebuild thread Midrange driver on one of the pair is deffo sub-optimal, and I'm looking to replace it/them. There's only so much you can patch up, rebuild, refoam, recolour...

As mentioned elsewhere I've just upgraded to a pair of JBL 705Ps. To feed them I've assembled PiCorePlayer on a Pi4 with a HifiBerry SPDIF HAT. This feeds the AES input nicely. So it's an all-digital signal path. Or is it? Does anyone here have an insight into the internals of the 70x series...

Has any serious testing been done on the Dayton Audio DSP-408? It seems to have amazing capabilities and at a fraction of the cost of corresponding Minidsp products. I would like to know if my old ears could tell the difference, I assume others have to be considering it. I don't mind a little...

Refurbishment over the last 5 years. Woofers refoamed. Midrange drivers refoamed. Ferrofluid replaced in HF tweeters. File Image Crossover capacitors replaced like for like, bipolar electrolytics from HifiCollective, back in 2018. Mundorfs and some others which are a nice green colour. Speaker...

Hi, I am quite happy with my Wharfedale Lintons, Marantz model 30 combo, however I'm thinking that a Sub could improve overall sound and improve distortion at higher volumes (95+dB). My thinking is that if possible, I use a HPF for RCA preamp line into the model 30, and a LPF for line to Sub...

Amir measured a dead spot at the cross over frequency right above the tweeter axis. This is readily apparent when playing a ~1.5 kHz tone and results in a musical reproduction that lacks presence: subjectively sound comes from around the speaker, not coherently from within the speaker...
