Building my first set of speakers.

Hmm, what exactly does that graph mean?

Hi,

the graph compares the Lyra bass response in a 50L sealed cabinet
version and the bass response in a 100L (floorstanding) reflex version.

Thanks for the replies guys.
The partsexpress kit looks a bit too simple...I have couple sets of 'nice' speakers that I enjoy...Wharfdale, Speakercraft, some Polks....The speakercrafts are my favorite...I don't know the model, but I just enjoy their sound.
Would this kit be comparable, better? To be honest, I want to WOW myself with the speakers I build. Would the partsexpress do this?

I don't mind spending a little time and money for something that I'll really enjoy. The Lyra design looks interesting....looks like something I could do. i've also been considering these t-lines http://www.geocities.com/bunkie21/frontview.html

Would this be suitable for the type of music i listen to?

Sorry, I'm a total freshie when it comes to speaker design, just looking for the best possible design, if it works out well who knows what this'll lead to. He tends to cross his tweeter way too low. In the Lyra, the xover point from his frequency respond was somewhere down below 1K which is way too low for a 2in tweeter. Unless you want sharp and bright stuffs, you would be better off finding some other design.



Any ideas?

You should think twice before building the Lyra. His speakers tend to sound really bright. I had a chance to build the Eros but it sounds really, really bright such that I ended up listen to the tweeter most of the time. He tends to cross his tweeter way too low. From the respond graph, the 2in tweeter was crossed over at somewhere below 1K which is way too too low. A 2in. tweeter is never supposed to go that low. This is simply a law of physics.
Unless you want bright and harsh stuff, please look somewhere else.

Hi,

I find your analysis a little simplistic. The Eros was optimised for
listening to on the end of a 300B valve amp chain and voiced
accordingly, I don't know what system you have.



The croosover point of domes very much depends on the electrical
slopes of the crossover. 1KHz is way too low for a 1" dome, not a 2".

You really can't say how low a mid-dome can go without knowing
its excursion capability and by implication distortion vs. frequency.

Have you personally heard the Eros? When you have finally listen to them then we can talk about it.

Sure an 2in may have an excursion ability to go below 1K but how well it can go that low is another matter. Just as a 7in. driver can be used with a 1in. tweeter in a two way system but a 7in. is probably not ideal to handle anything above 2khz.

I have the dayton BR-1 PE kit and must say that if you're into loud, there are better things you can get. And please skip those golden boys. I'd look for another 2-way to avoid high cost of woofer to mid xovers. I think this should fit in your budget.
