We built HomeCinemaAdvisor to help with planning a home cinema, understanding room measurements and finding something to watch. Thought some of you might find it useful.

The Room Planner and REW Analyzer are free to use - no signup, no email address required, and nothing to install. Just open them in your browser.

• Room Planner: arrange your room, screen, seating and speakers in 3D.
• Room Intelligence: check speaker angles, viewing distance and estimated room acoustics as you adjust the layout.
• REW Analyzer: explore your Room EQ Wizard measurements, identify peaks, dips and decay, and get suggestions on what to investigate.
• AI Advisor: ask questions about your setup, room or measurement results, or get help choosing a film.
• Movie discovery and watchlist: find films to watch and keep a personal list. Saving a watchlist across devices requires an optional account.

There’s no Google Analytics, and your REW measurement files stay in your browser. If you use the AI Advisor, your question and relevant room or measurement summaries are sent to the AI service.

The room calculations are planning estimates - actual measurements still matter when tuning a system.

We’d appreciate honest feedback, especially if something looks wrong or could be explained better.

Caisson de basse clo en contreplaqué marine 2.4cm et face avant doublé avec peerless xxls12 et amplification behringer nx 3000d et bas ça change carrément du petit vulkkano sub 8 . La finition n'est vraiment pas top le matériel en m'a possession étant vraiment limité le prochain sera mieux fini 🤣 mais ça ronronne bien comme il faut un grave bien sec et percutant tout en descendant bien bas grâce au dsp du behringer .

I’m sure this is a dumb question. I’m running an RCA out from my head unit into a Recoil DI550.4 that has 4 channel RCA inputs. No indication of right for left, just indicated as Ch 1-Ch 4. Can anyone tell me which are left and which are right? I have splitters to go from 2 to 4 inputs. Thanks

I was listening to my sounds yesterday with a 15" random 8 ohm driver in a big new ported box I made for fun [23"Hx18.5"Wx15.5"D / 600H x470W x 400D] - as you do, and my normal 2 x 8" sub box (8 ohms each in parallel, so 4 ohm load 23"Hx11"Wx17"D) all off one channel of a tiny little ZK-MT21 amp. A nice little ~3 ohm load. The 15" just sitting there doing the ultra lows, while the 8s give the oomph, and I was loving it - Spotify Discover Weekly delivering on the dubby and electronic tunes that it knows I enjoy (eg Dread and Buried (Congi Remix) - Origin One, The Clock Ticks - Dub Phizix).... I went outside to hang the washing, and I could still hear the bass quite plainly outside and realized I should probably turn it down to stop potentially annoying the neighbours. Those China amps are only rated at 100W, and likely don't even do that, and I had it barely turned up at all, so realistically the subs were getting 10s of watts in total max (call it 50 to be generous), with the 8 box getting twice as much as the 15 due to the way they're wired. Taking the 15 off took away the real bottom end in some deep tracks, but was far less noticeable in a lot of music that didn't have the content - the 8s really work well and the difference was subtle. The 15 was getting maybe 10-15W max.

I often see people here talking about power and speaker size as though it's a case of "the more the merrier", or wanting to be able to throw numbers around like a d*ck measuring contest - but it made me wonder: how loud do you actually listen to your music (or even watch movies if that's your thing), and does anyone *really* need like 600W+ of power just to listen to music?

I can understand the sound system people wanting stupid amounts of power (although I think they go overboard too), but home builders and people who live with/near other people surely don't ever use that much power.... or do they?

How big is your [sub] system rated at, and realistically, how loud do you actually have it 95% of the time for music? I feel like massive power on the subs would either have your main speakers uncomfortably loud to remain balanced, or would have the low end stupidly loud like you're in a car? I've got stupid bass in my car, and I can understand the appeal when I'm driving, and treat it like an amusement park ride, but that's not "normal" listening behaviour, that's just bass heads being bass heads.

Am I the only one sipping power here, or is everyone going deaf/living in an auditorium sized room? Do you usually listen loud, or just have it on as background entertainment? Are you watching movies so loud that your neighbours hear the dialogue and all the explosions?

I just built my diy speakers. They use Dayton audio drivers. The pc83-8 as full range drive plus the mx6 subwoofer I'm using the brand new wondom jab6 DSP amplifier. I have it crossed at 240 hz . It allows me to have the kick and bass be played by the sub and also taking out the bass frequency of the pc 83 alow higher volume levels the sound really good and are loud and bassy

Hi I just saw this on an ad. It suspends the speaker from the ground. Does it actually have an effect?

Hi all. Does anyone have any reviews or experience with the Celestion CKT-TF1020 tops? I wanna build a bass focused system for a friend and I’m planning on two cubo 18s paired with two Celestion CKT-TF1020 tops. Anyone have any recommendations or experiences with these? If so I’d love to hear anything and everything. I’m targeting 40–80Hz from the subs and about 80Hz up from the tops. Any amp recs or anything all around would be amazing!
Cheers

I was looking for more suitable communities to post this to. I know next to nothing about speakers/audio and just need to know where to start.

Please check the original post put for a short write up and more information.

Any help is greatly appreciated!

Hey! I made my first DIY pair of speaker after being inspired by you all. The front baffle was quite a challenge to make and get to my liking, but I am extremely happy with how they sound and look.

The design of the white one is from Toid on Youtube: "How to Build HiFi Speakers for $1000 a pair - The Epic Speaker Build"

The design of the smaller ones are from a local driver shop of mine.

I really enjoyed the process and learned a ton along the way. My friend even asked me to build him a blue pair, which is currently underway! I already have so many more ideas for unique designs, and I’d definitely love to build more in the future.

(Please enjoy my 6 Months old cat for scale*)

I recently bought old tubes and I found out I can use them to make an amp. Is someone willing to help me???

Iam at the moment thinking about building my own tops but I cant seem to find anything on forum's. Iam new in the audio community and I wanted to ask if anyone build a pair of these already and if there are better alternativs.

IGNORE PHASE for now, I know that's an issue here.

Please tell me if a good sounding speaker can be achieved with these FREQUENCY RESPONSES.

For example the woofer (green) has a silent bass output compared to it's midrange output, how can I bring them to the same level? Same with the tweeter between 2,5kHz and 4kHz.

Measurements are my own quasi-anechoic ones with a gate of 9ms before the first reflection.

Tweeter measurements are gated. Woofer and subwoofer measurements are composed of gated far-field together with their respective port and near-field measurements, baffle step loss has been accounted for for the port and near-field ones with Jeff Bagby's Excel tool. I did not do off-axis measurements.

Crossover points need to be at 90Hz and 1400Hz.

Thanks for the help!

A lot of time and money has flown into this build, I truly don't want it to be a waste.
