    Hi everyone,

    I'm thinking of making a 2 way, self powered center channel for home based on sale items at Madisound.

    The speaker has to be relatively low profile, so it sits in front of my TV, so I'm going to try the Eton 4" that's on sale and an undecided tweeter.

    I'll be trying out the Hypex 2 way plate amp with DSP. This way I don't have to have a new amplifier. This also gives me a lot of flexibility in tuning the crossover, and no chance at all to use boutique capacitors in the crossover. :)

    Do any of you have opinions after listening to the following? Good or bad?

    Vifa XT25BG60-04
    SEAS Excel T25CF-001
    Audax TW025A28
    Fountek NeoCD 1

    Also, part of my problem is I really have no access to a woodshop anymore, so whatever I do it will have to be easy with hand tools. I have a router and circle guide though. And I'll probably only make 1 of these. I already have surrounds and amps for them.

    I'm really curious about the Fountek, since I do like my esoteric tweets.

    Best,


    Erik

    A small diameter face plate dome + 6" midbass can often have equal height to a typical 4" diameter dome faceplate + 5" midbass.
    ----low cost center channel----
    SBAcoustics has the $25 SB16PFC25-8 6" Paper Cone Woofer. F3~37Hz in ported 0.9cuft (short but wide)
    SBAcoustics has the $20 SB19ST-C000-4 dome where the plastic face plate can be trimmed to 70mm. Fs=980Hz
    SBAcoustics $33 SB26STCN-C000-4 dome faceplate can be cut down to 62mm Fs=960Hz great sound!

    I've used both tweeters mentioned above, both are excellent values.

    Hi Face,

    Thanks for the advice, that is of course the best way to go about this.

    I used to work in theater sound, for one of Dolby's competitors. I know more about Dolby Surround than probably anyone left at Dolby. My technical knowledge ends there though, I was long gone by the time DTS and Dolby Digital came out. 20 years later the bastards are still making my life miserable by building next to my apartment and using jackhammers all weekend long.... but I digress.

    If money were no object, your suggestion would of course be ideal, but I really blew my budget on my mains, ended up costing around $3,000 for the pair and I'd like to avoid spending $1,500 on the center. Part of it is just being cheap. Part of it is that after observing what happens when I stream, only a few movies and TV shows actually have 5.1 content. The rest don't use the center at all. This may have to do with how the Oppo handles a phantom center. So, about 70% of the time the center is just going to be sitting there looking pretty.

    After having some experience with a 3rd party speaker, in my home, I have to say that timbre matching matters more than driver matching. My main speakers use Mundorf AMT's and ScanSpeak Revelators. Using a small, and really cheap center that happens to be well made and have a very flat mid to treble I was really happy. I was actually surprised in a home with a screen much smaller than 40' across a center channel mattered at all.

    Actually I was so happy I had to measure them, and discovered that they are a very good match for my mains. Canadian company that is now out of business, but measurably and internally, what great little speakers.

    Now I want to make a center though, and re-purpose that speaker for the surrounds. Also, I want it to be powered so I can avoid buying another amplifier and I am looking forward to playing with DSP crossover and equalization. Looking at the FR charts for the SB tweeters it seems they'd be a great match.

    I could of course re-work my current designs into a 2 way center. Using the same tweeter, with a 5" ScanSpeak for instance. It's an option, but an expensive one. :) Plus, I want to play with other drivers now. I know how good the Mundorf/SS combo is, now I want to play with Eton woofers.

    Best,


    Erik
